Astronomers discover 83 supermassive black holes 13 billion light-years away

Washington, Mar 15: Astronomers have discovered 83 quasars powered by supermassive black holes 13 billion light-years away from the Earth, from a time when the universe was less than 10 per cent of its present age.

“It is remarkable that such massive dense objects were able to form so soon after the Big Bang,” said Michael Strauss, a professor at Princeton University in the US.

“Understanding how black holes can form in the early universe, and just how common they are, is a challenge for our cosmological models,” Strauss said in a statement.

This finding, published in The Astrophysical Journal, increases the number of black holes known at that epoch  considerably, and reveals, for the first time, how common they are early in the universe’s history.

In addition, it provides new insight into the effect of black holes on the physical state of gas in the early universe in its first billion years.

Supermassive black holes, found at the centers of galaxies, can be millions or even billions of times more massive than the Sun.

While they are prevalent today, it is unclear when they first formed, and how many existed in the distant early universe.

A supermassive black hole becomes visible when gas accretes onto it, causing it to shine as a “quasar.” Previous studies have been sensitive only to the very rare, most luminous quasars, and thus the most massive black holes.

The new discoveries probe the population of fainter quasars, powered by black holes with masses comparable to most black holes seen in the present-day universe.

The team used data taken with “Hyper Suprime-Cam” (HSC) instrument, mounted on the Subaru Telescope of the National Astronomical Observatory of Japan, which is located on the summit of Maunakea in Hawaii.

The researchers selected distant quasar candidates from the sensitive HSC survey data.

They then carried out an intensive observational campaign to obtain spectra of those candidates, using three telescopes: the Subaru Telescope; the Gran Telescopio Canarias on the island of La Palma in the Canaries, Spain; and the Gemini South Telescope in Chile.

The survey revealed 83 previously unknown very distant quasars.

United Nations, Jan 2: Nearly 400,000 babies were born around the world on New Year's Day with India recording the highest number of these births worldwide at 67,385, the UN children's agency said.

An estimated 392,078 babies were born around the world on New Year's Day, according to UNICEF. Of this, an estimated 67,385 babies were born in India, the most globally. China comes in second with 46,299 births.

The beginning of a new year and a new decade is an opportunity to reflect on our hopes and aspirations not only for our future, but the future of those who will come after us,” UNICEF Executive Director Henrietta Fore said.

As the calendar flips each January, we are reminded of all the possibility and potential of each child embarking on her or his life's journey—if they are just given that chance.”

Fiji in the Pacific most likely delivered 2020's first baby, while the US, the last of the New Year's Day. Globally, over half of these births were estimated to have taken place in eight countries - India (67,385), China (46,299), Nigeria (26,039), Pakistan (16,787), Indonesia (13,020), United States of America (10,452), Democratic Republic of Congo (10,247) and Ethiopia (8,493).

Each January, UNICEF celebrates babies born on New Year's Day, an auspicious day for child birth around the world, it said. However, for millions of newborns around the world, the day of their birth is far less auspicious.

In 2018, 2.5 million newborns died in just their first month of life; about a third of them on the first day of life. Among those children, most died from preventable causes such as premature birth, complications during delivery, and infections like sepsis. In addition, more than 2.5 million babies are born dead each year.

UNICEF said over the past three decades, the world has seen remarkable progress in child survival, cutting the number of children worldwide who die before their fifth birthday by more than half. But there has been slower progress for newborns. Babies dying in the first month accounted for 47 per cent of all deaths among children under five in 2018, up from 40 per cent in 1990.

UNICEF's Every Child Alive campaign calls for immediate investment in health workers with the right training, who are equipped with the right medicines to ensure every mother and newborn is cared for by a safe pair of hands to prevent and treat complications during pregnancy, delivery and birth.

Too many mothers and newborns are not being cared for by a trained and equipped midwife or nurse, and the results are devastating,” said Fore. “We can ensure that millions of babies survive their first day and live into this decade and beyond if every one of them is born into a safe pair of hands.”

India is projected to surpass China as the world's most populous country around 2027. According to UN estimates, India is expected to add nearly 273 million people between 2019 and 2050, while the population of Nigeria is projected to grow by 200 million. Together, these two countries could account for 23 per cent of the global population increase to 2050.

China, with 1.43 billion people in 2019, and India, with 1.37 billion, have long been the two most populous countries of the world, comprising 19 and 18 per cent, respectively, of the global total in 2019. Through the end of the century, India is estimated to remain the world's most populous country with nearly 1.5 billion inhabitants, followed by China with just under 1.1 billion, Nigeria with 733 million, the US with 434 million, and Pakistan with 403 million inhabitants.

Dubai, May 7: As India begins the world’s largest evacuation mission by repatriating its overseas citizens stranded due to COVID-19, as many as 354 of them from the UAE will fly into their home country in the first two flights to Kerala today.

An Air India Express flight, which is scheduled to take off from Abu Dhabi to Kochi at 4.15 pm is the first flight, which will be followed by a Dubai-Kozhikode flight of the same airline at 5.10pm. The Indian missions in the UAE finalised the list of passengers, who were chosen based on the compelling reasons they submitted while registering their names.

Selection criteria

These include pregnant women and their accompanying family members in some instances, people with medical emergencies, workers and housemaids in distress, families with cancelled visas, bereaved family members who couldn’t attend funerals back home, a few students and stranded visitors and tourists including two brothers who got stranded in Dubai International Airport for 50 days, the missions said.

Short-listing the first passengers from among a database of more than 200,000 applicants, who include around 6,500 pregnant women, has been a mammoth task which posed several challenges for the missions, Neeraj Agrawal, Consul Press, Information and Culture at the Indian Consulate in Dubai told Gulf News.

He said the consulate set up an operations room in a tie-up with community volunteers from Kerala Muslim Cultural Centre, Indian Association Ajman, AKCAF Task Force, the BAPS Mandir, Indian People’s Forum, and Tamil Ladies’ Sangam.

 “We are trying to accommodate as many deserving people as possible. We expect the understanding of the people. It has been very difficult to sort out everyone’s urgency.”

“We cannot do a lottery system in this and we had to make sub- categories to ensure there is a mix of people with different types of urgencies.”

“Though we want to give priority to pregnant women, it is practically not possible and not good for the health and safety of the applicants to allot a lot of them on the same flight.”

He said 11 pregnant women have been issued tickets on the Dubai-Kozhikode flight.

“That is the threshold we can allow on a flight.”

Volunteer support

The consul appreciated the support of the volunteers in finalising the flight manifest.

“But our response ratio was very less. Many people whose names came up on top of the list were not willing to go on the first flights.”

Due to various constraints like this and sometimes the details of accompanying persons not readily being available, he said the mission was not able to quickly reach out to who might be really in need.

“However, we have given due consideration to people who got in touch with us with their emergency needs. At the time of issuing tickets, we had about 20 such cases.”

He said the Consul General of India in Dubai Vipul led the entire operation and Pankaj Bodkhe, consul, education, was in charge of the Dubai flight.

A big challenge

“It has been a big challenge. Our only concern is that despite our best efforts, sometimes people with more compelling reasons might have got left out on the first flights because of the volume of people who have reached out to us.”

Since there is a chance that some passengers with tickets might not be allowed to fly if they fail the medical screening including blood tests to check antibodies for COVID-19, he said some applicants in the waiting list have been asked to be on standby at the airport.

People with emergencies wishing to fly to other destinations also could not be included, he pointed out.

“We had to ask them to wait. We are unable to send them to other destinations. We can see their desperation. We feel sorry and desperate.”

He said the government is trying to add more flights to un-chartered destinations and a new flight from Dubai to Kannur has been added on May 12.

Passengers of today’s flights have been urged to reach the airport four to five hours prior to departure to facilitate the medical screening.

New Delhi, Feb 10: Former finance minister P Chidambaram on Monday tore into the Modi government's handling of the economy, saying it was close to collapse and was been attended by "very incompetent doctors."

Initiating the debate on the Union Budget for 2020-21, he said rising unemployment and falling consumption was making India poorer.

The economy, he said, is facing demand constraints and is investment starved. The economy is facing fall in consumption and rising unemployment.

"Fear and uncertainty prevails in the country," he added.

He said the chief economic advisor to the BJP government for four years, Arvind Subramanian has stated that the economy is in the ICU. But "I would say the patient has been kept out of ICU and incompetent doctors are looking at the patient," Chidambaram said.

"It is dangerous to have a patient out of ICU and being looked upon by incompetent doctors. What is the point standing around and chanting slogan 'Sab ka saath, sab ka vishwas'," he said, adding every competent doctor the Modi government could ever identify has left the country.

His said a list of such people included former RBI governor Raghurman Rajan, former CEA Arvind Subramanian, former RBI governor Urjit Patel and former NITI Aayog vice chairman Arvind Panagariya.

"Who are your doctors, I want to know," he said, adding the government considers Congress as untouchable and doesn't think of any good about the rest of the opposition and so doesn't consult them.

Chidambaram charged that instead of putting money in the hands of people, the Modi government "put money in hands of 200 corporates" by way of corporate tax.

He said Finance Minister Nirmala Sitharaman in her 160- minute budget speech did not talk of the economy and its management.

"You are living in echo chambers. You want to hear your own voice," he said.

Listing problems with the Modi government, Chidambaram said it refuses to admits in mistakes, lives in denial and has predispositions.

The demonetisation of old 1000 and 500 rupee notes, as well as the hurried implementation of the Goods and Services Tax (GST), are "monumental blunders" that ruined the economy, he said, adding the Modi regime is predisposed to protectionism, a 'strong' rupee and is against bilateral and multilateral agreements.

"It is living in denial," he said, adding the economic growth has fallen for hereto unseen six consecutive quarters.

He wondered on the narrative Finance Minister Nirmala Sitharaman was trying to give after reading out a 160-minute budget speech with few pages left unread.

Her budget neither made any reference to the Economic Survey nor picked up a single idea from it, he said.

Chidambaram, who is credited with presenting a 'dream budget' more than two decades back, said the GDP growth has declined for six consecutive quarters, agriculture is growing by just 2 per cent, while consumer price inflation has risen from 1.9 per cent in January 2019 to 7.4 per cent in a matter of 11 months.

Also, food inflation is at 12.2 per cent. Bank credit is growing 8 per cent with non-food credit rising by 7-8 per cent and credit to industry by just 2.7 per cent. Credit to agriculture has declined from 18.3 per cent to 5.3 per cent and that for MSMEs from 6.7 per cent to 1.6 per cent.

Overall industrial index showed just 0.6 per cent growth. "Every major industry is either near zero or in negative zone," he said, adding thermal power plants are operating at just 55 per cent of the capacity as factories have either closed or are on the verge of closure.

"That gives you a good picture of the state of economy. You don't require MRI," he said. "You are in management for six years. How long can you blame previous managers."

He charged the government with burying unfavourable reports such as the labour survey that put unemployment at 45 -year high of 6.1 per cent at end of 2017-18. Also, consumer expenditure has falling to 3.7 per cent between 2011-12 and 2017-18.

Drilling holes in Budget numbers, he said the 2019-20 budget projected a nominal GDP growth of 12 per cent but ended with just 8.5 per cent. Fiscal deficit was targeted to be shrunk to 3.3 per cent of the GDP but ended by at 3.8 per cent and in the next fiscal it is being targeted at 3.5 per cent.

Revenue deficit was targeted at 2.3 per cent in fiscal ending March 31, 2020 but ended up at 2.4 per cent and in the next it will rise to 2.8 per cent, he said, adding capital expenditure in the next fiscal will shrink to 0.7 per cent from 1.4 per cent in the current.

Net tax revenue in the current fiscal was targeted at Rs 16.49 lakh crore but only Rs 9 lakh crore was collected in first nine months till December 2019 and "you want us to believe this will rise to Rs 15 lakh crore by March 2020," he said.

Similarly, expenditure in 2019-20 was pegged at Rs 27.86 lakh crore but only Rs 11.78 lakh crore spent during April- December and by March this is projected to rise to Rs 27 lakh crore.

"You have no money to spend... and these are masked by numbers," he said. "Numbers are not easily acceptable or believable."

Chidambaram said the government is facing shortfall in all forms of taxes - Rs 1.56 lakh crore on corporate tax, Rs 10,000 crore on personal income tax, Rs 30,000 crore on customs, Rs 52,000 crore on excise and Rs 51,000 crore on GST.

This despite "the extraordinary powers" and "all kinds of power" given to lower level tax officials, he said.

He read of list of heads under which allocation has fallen - food subsidy, agriculture, PM-Kisan, rural roads, mid-day meal scheme, ICDS, skill development, Ayushman Bharat, rural development and MGNEGA.
