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.

Jan 27: Bollywood Film Director Anurag Kashyap, who has been vocal about his political views on social media, slammed Union Minister Amit Shah and accused him of being 'cheap'.

"How timid our Home Minister is. Its own police, its own goons, its own army and security increases and invades unarmed protestors. Amit Shah has crossed the extent of cheapness and inferiority. History will spit on this animal," Kashyap tweeted.

The film director has taken an active part in the anti-Citizenship Act protest rallies and was against the Jawaharlal Nehru violence. He also came in support of his contemporary Deepika Padukone when the latter faced backlash for showing up at JNU in support of the students.

New Delhi, Feb 3: The Allahabad High Court on Monday granted bail to former BJP leader Swami Chinmayanand in the alleged rape case of a law student. He was arrested in September last year after the 23-year-old woman accused him of sexual harassment and blackmail.

The woman was a student of the Chinmayanand-controlled SS Law College in Shahjahanpur in Uttar Pradesh.

Chinmayanand is facing charges under Sections 376C (sexual intercourse by a person or persons taking advantage of their official position), 354 D (stalking), 342 (wrongful confinement) and 506 (criminal intimidation) of the Indian Penal Code (IPC).

The case is being investigated by a Special Investigation Team (SIT) formed on the directions of the Supreme Court.

The case came to light after the woman posted a video on August 23 last year on social media alleging that “a senior leader of the saint community” was harassing and threatening to kill her. The law student went missing a day later, after which her father lodged a complaint, accusing Chinmayanand of harassing his daughter.

Chinmayanand was expelled from the BJP after his arrest.

The SIT had, on November 6, submitted chargesheet in the case.

In a parallel case, the woman was charged with trying to extort money from Chinmayanad. The Allahabad High Court granted her bail in that case in December last year.

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.
