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.

Mangaluru, Jan 15: The coastal city of Mangaluru witnessed a historic event as a sea of humanity converged at the Shah Gardan Maidan in Adyar-Kannur to register their protest against the Citizenship (Amendment) Act (CAA), National Register of Citizens (NRC) and National Population Register (NPR) besides the “categorical mistreatment” of Muslim community at the hands of the police across the country including in Mangaluru.

The protest is jointly being organised by the various Muslim organisations of Dakshina Kannada and Udupi district under the leadership of Muslim Central Committee. 

The main staged is named after Shaheed Jaleel Kudroli and Shaheed Nausheen, who were ruthlessly gunned down by the police during a chaos that erupted on December 19 in the city due to police batten charge against people during a minor protest against NRC. 

Even thought the police had banned public transport and blocked the highway to reduce the number of protesters, around one-and-a-half lakh people had reached the venue when the historic meeting commenced at 2:30 p.m. By 4 p.m. the number of protesters crossed 2 lakh, according to the organisers.

Both sides of the highway were filled with those who came to witness the rally and traffic went haywire along a five-kilometre stretch of the road. The people who took part in the rally were seen waving national flags.

The protest rally was inaugurated by Udupi Khazi Bekal Ibrahim Musliyar. Dua was offered by Dakshina Kannada Khazi Twaka Ahmed Musliyar. 

Addressing the protesters, former IAS officer and activist Kannan Gopinathan alleged that the Centre wants to create fear among all sections of people and silence them. Society began to protest when the government crossed the limits and put curbs on democratic freedom, he claimed.

The Centre thought that they can get away with CAA and NRC. However, people have realised the truth and have started coming out onto the streets, Gopinathan added.

Activist Harsh Mander said the theme of the protest against the CAA and NRC is "national flag in one hand, Constitution is another and people will march forward with love in their hearts”.

“The fight against NRC is the fight for the protection of our Constitution. The BJP is using NRC as a weapon to divide the people after Article 370 and Ram Mandir construction," he said and warned the Centre: “The more you try to divide us, the stronger and united we’ll be”

Human rights activist Shivasundar said the "chowkidar" appointed by the people is now asking them whether they are the real owners of their houses.

The BJP only delivered hollow promises which is evident from the rising unemployment, fall in GDP, farmers suicides and the economic slowdown, he alleged.

MLA UT Khader, MLC BM Farooq, former MLA Mohiyuddin Bava, Muslim central committee president KS Mohammed Masood, Ullal Qazi Fazal Koyamma Tangal, Dakshina Kannada district Wakf committee president UK Monu Kanachur, Sunni Youth Federation state general secretary Abdul Rashid Zaini and Karnataka Samastha Mushavara state secretary UK Abdul Aziz Darimi were present among others.

useless protest , Modi is not manmohan singh , amit shah is not chidambaram .. they are trained RSS men and once RSS men decide they wont go back .jihadists must understand that they cannot win globe with their mentality , thats why you guys flood christain countries in the name of prosecution and believe only population explosion can achieve your dream of darool uloom .ummah is a total flop and islamic countries are just even unable to face israel , forget about others . as per my observation , hindus were secular before , but nowadays in large no they are quitting this kind of secularism .even 10% of hindus become radicalised then it will be big probelm for anti india forces .muslim organisations are totally misleading muslim community in the name of CAA

New Delhi, Feb 16: RSS chief Mohan Bhagwat on Saturday said everyone is unhappy in the society and constantly agitating notwithstanding a "many-fold rise" in materialistic comforts and pleasures.

Addressing a gathering of Sangh workers and intellectuals here in Gujarat, Mr Bhagwat also said that even political parties who are not in power are also agitating.

"Inspite of increase in comforts and materialistic pleasures, everyone is unhappy and is staging agitations. Be it owner or servant, a party in opposition, the common man students, teachers, everyone is unhappy and dissatisfied," the Rashtriya Swayamsewak Sangh (RSS) chief said.

He was speaking on the topic "India's Role in the Present World Context".

Mr Bhagwat further said that bigotry, violence and terrorism are on the rise in the present world.

"India has to give 'dharma'  (wisdom) to the world so that knowledge spreads but humans do not become robotic. We have always talked about the concept of global family but not global market," he said.

The lecture was organised by "Madhav Smruti Nyas", an organisation backed by the RSS.

"To think that we are living in a better world is a half truth. Facilities are not evenly distributed. Rule of Jungle is prevailing. A capable person is crushing the weak to climb up. Knowledge is used more for the destruction of the world," the Sangh chief said.

Mr Bhagwat said people are also misusing social media by spreading "false information" to create controversies.

He also stated that trying to put "everyone into one uniform" is also a form of bigotry.

"US and Russia are super powers. China would become a super power too. Now, what super power nations did to others? They just took control of other countries for their own selfish agenda. These super powers gave it back only when they were asked to do so. Otherwise, they never gave anything to others," said Mr Bhagwat.

New Delhi, Feb 16: Aam Aadmi Party (AAP) national convener Arvind Kejriwal was on Sunday sworn-in as the Chief Minister of Delhi for the third time in a row at Ramlila Maidan here, after his party registered a massive victory in the recently concluded Delhi Assembly polls.

Kejriwal was administered the oath of office and secrecy by Delhi Lieutenant Governor Anil Baijal.

The sprawling Ramlila Maidan reverberated with sounds of thousands of people cheering for the AAP leader.

Kejriwal who received a hero's welcome here had extended an invitation to the people of Delhi urging them to attend the swearing-in ceremony to witness "the son of Delhi" taking oath today.

The AAP nearly repeated its 2015 performance in the elections, sweeping the Assembly polls winning 62 seats in the 70-member Assembly, in the face of a high-voltage campaign by the BJP, which fielded a battery of Union Ministers and Chief Ministers in its electioneering spearheaded by Home Minister Amit Shah.
