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.

Mumbai, Mar 9: India's Yes Bank will not be merged with State Bank of India, which is set to infuse funds in the beleaguered lender, the newly appointed administrator leading the rescue plan said in a television interview on Monday.

"There is absolutely no question of a merger," Prashant Kumar, the administrator, told the CNBC TV18 channel.

The Reserve Bank of India (RBI) on Thursday took control of Yes Bank, after the lender - which is laden with bad debts - failed to raise the capital it needs to stay above mandated regulatory requirements.

Placing Yes Bank under a 30-day moratorium, the central bank imposed limits on withdrawals to protect depositors and said it would work on a revival plan. The move spooked depositors, who rushed to withdraw funds from the bank.

Kumar, a former finance chief at SBI, assured depositors their money was safe and that the moratorium on Yes Bank might be lifted much before the deadline on April 3 and normal banking operations might resume as early as Friday.

He also mentioned that the withdrawal limit of Yes Bank may be removed by March 15, 2020.

SBI Chairman Rajnish Kumar said on Saturday the state-run bank would need to invest up to 24.5 billion rupees ($331 million) to buy a 49% stake in Yes Bank as part of the initial phase of the rescue deal, adding that the survival of troubled lender was a "must".

Jan 15: Uttar Pradesh Chief Minister Yogi Adityanath said on Tuesday that the Muslim population in India increased manifold since the partition because they were given special rights and facilities, according to a report by The Indian Express.

"The Muslim population in India has increased manifold since 1947, it has gone up by seven to eight times. No one has any objection. If they, as citizens of the country, work for development, they are welcome. Their population has increased because they have been given special rights and facilities. All possible steps were taken to ensure their growth," Adityanath said while addressing a rally in Gaya organised by the BJP in support of the Citizenship (Amendment) Act.

He asked the audience, "But what happened in Pakistan?" Claiming that the Hindu population in Pakistan had decreased since 1947, he asked why it was so.

Yogi said that the countrywide anti-CAA protests are a "conspiracy" hatched from afar by those resentful of a united and grand India and these are being aided by a "crooked" opposition. He further charged that those opposing the legislation were committing the "paap" (sin) of working against national interests.

"For taking such a step, Prime Minister Narendra Modi and Home Minister Amit Shah deserve acclaim. Instead, they are being attacked", Yogi lamented.

He himself contradicts his statements. He claims the Muslim population rose 8-9 (according to him) times since 1947. If he was educated its simple 73 years have passed the population grows. Still, the Muslim population is only a minority against the majority. He talks about special rights and facilities given yes agreed but not by him it's by the Constitution of India and for all the minorities. So it's not you its Constitution of India.  The majority of the people are against the act CAA is against the very fundamental of the Constitution of India which PM & HM are taking away from the people. If you disagree, disrespect, go against it then you are against the country itself in Hindi deshdruhi.

Lucknow, Jun 20: A media body on Saturday described as "an act of intimidation" the filing of an FIR in Uttar Pradesh against a journalist over a report on the impact of the lockdown on a village, saying it was part of an "established pattern" of harassment of independent scribes.

In a statement, the Media Foundation put on record its strong protest over the FIR filed by the Uttar Pradesh government against Supriya Sharma, executive editor of news portal Scroll.in.

The case was filed against Sharma for allegedly misrepresenting facts in a report on the impact of the lockdown in a village adopted by Prime Minister Narendra Modi, police sources had said on Thursday.

The FIR against Sharma and the Scroll editor-in-chief is an "an act of intimidation and a case of abuse of process", intended to discourage honest and critical reporting, the Media Foundation said.

The Media Foundation was started in 1979 with the aim of upholding freedom of speech, expression and information.

The FIR against Sharma is only the latest instance of similar coercive actions against professional journalists, part of "an established pattern of harassment and humiliation of independent journalists", it said,

"It is an unacceptable encroachment on press freedom," said the foundation, whose chairperson is veteran journalist Harish Khare.

The Media Foundation called upon the judiciary, and central and state governments to uphold the spirit of freedom of speech and expression as guaranteed in the Constitution.
