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.

New Delhi, Mar 6: Shares of YES Bank and State Bank of India came under huge selling pressure on Friday as developments unfolded regarding SBI picking stake in the private lender. Shares of the lender hit record low of Rs 5.55, plunging 85 per cent, and were trading below its previous low of Rs 8.16 hit on March 9, 2009.

SBI, on the other hand, slumped 11 per cent to Rs 257.35 on the BSE. The benchmark S&P BSE Sensex was trading with a cut of over 3 per cent at 37,251.37 level.

In the past three months, share price of the private lender has plunged 41 per cent, while the state-owned lender has slipped 14 per cent. In comparison, the S&P BSE Sensex has dipped 5.6 per cent till Thursday.

On Thursday, the Reserve Bank of India superseded the board of troubled private sector lender YES Bank and imposed a 30-day moratorium on it “in the absence of a credible revival plan” amid a “serious deterioration” in its financial health.

During the moratorium, which came into effect from 6 pm on Thursday, YES Bank will not be allowed to grant or renew any loans, and “incur any liability”, except for payment towards employees’ salaries, rent, taxes and legal expenses, among others.

This is the first time that a bank of this size will be put under a moratorium by the RBI.

“The financial position of YES Bank had undergone a steady decline “largely due to inability of the bank to raise capital to address potential loan losses and resultant downgrades, triggering invocation of bond covenants by investors, and withdrawal of deposits,” RBI said in a statement.

“After the moratorium, the next step will be to infuse to money and keep the bank afloat. So from shareholders’ point of view, the future is certainly hazy as the capital requirement is huge. The good part, however, is that the RBI has stepped in and depositors don't have to worry,” says Siddharth Purohit, a research analyst at SMC Securities.

Meanwhile, analysts at Nomura believe that placing the Bank under moratorium implies that equity value in the bank would be negligible, and that the chances of private capital participating in future capital raising plan are near zero.

"Any resolution for Yes Bank is more proposed from the perspective of deposit holders and systemic stability, and not from the perspective of Yes Bank equity investors or even perpetual bond holders," they wrote in a note dated March 6.

In another development, SBI’s Board Thursday gave in-principle approval to consider an “investment opportunity” in YES Bank, even as it said “no decision had yet been taken to pick up stake in the bank”.

According to a  report, highly-placed sources indicated a rescue plan involving SBI and Life Insurance Corporation of India (LIC) was being discussed and an announcement in this regard might be made soon.

“While the finer details of the deal are being worked out, it is anticipated that both SBI and LIC together will take a 51 per cent stake in the bank, with a one-year lock-in period,” the report said.

Most analysts believe it is a positive step for the Indian financial sector as the government has tried to avoid a repeat of IL&FS-like crisis.

“The move is a positive step for the financial sector as a whole. By this, the government has tried to avoid a repeat of IL&FS-like crisis and has saved the depositors,” said AK Prabhakar, Head of Research at IDBI Capital. While we know that YES Bank has a huge pile of bad loans, SBI is the only bank that has the capacity to absorb it, he added.

However, the valuation at which YES bank would be taken over remains a cause of concern.

Global brokerage firm JP Morgan Thursday cut its target price for YES Bank on Thursday to Rs 1 per share, taking into account the potential fall in the lender’s net worth due to stressed assets.

“We believe forced bailout investors will likely want the bank to be acquired at near-zero value to account for risks associated with the stress book and likely loss of deposits. We think the bank will need to be recapitalised at nominal equity value and could test dilution of additional tier 1 (AT1) capital. We remain underweight and cut our target price to Rs 1 as we believe net worth is largely impaired,” JP Morgan said in a note.

Global brokerage firm Nomura estimates a need of Rs 25,000-44,000 crore and adjusted for Rs 7,400 crore of current coverage, if the current stress of Rs 65,000-70,000 crore faces 70 per cent loss given default (LGD).

"It implies Rs 18,000-37,000 crore needed for provisioning against the current net worth of Rs 25,700 crore Also, to run as going concern, the bank would require over Rs 20,000 crore of CET-1 capital as well," the note said.

YES Bank has registered slippages of Rs 12,000 crore so far in FY20, while it has placed Rs 30,000 crore of loan assets under the watch list. Its deposits stood at Rs 2.09 trillion on September 30, 2019, while its advances totalled Rs 2.24 trillion. The bank has delayed publishing its December quarter results by a month to March 14.

Lucknow, Jan 6: Undeterred by the large scale protests that claimed as many as 20 lives in the state, Uttar Pradesh government has started the process of implementing the controversial Citizenship (Amendment) Act.

According to sources in the government, the district magistrates have been directed to identify the migrants from Pakistan, Bangladesh and Afghanistan, who have been living in their districts.

Sources said that the state home department has given oral instructions to the district magistrates. ''No written orders have been issued,'' said a senior official here preferring anonymity.

The official said that the district magistrates would be preparing a list containing names of those minorities, who had migrated from these countries following their persecution and had been living without obtaining the citizenship of India.

According to sources, the government expected that the migrants, who could be eligible for the Indian citizenship in accordance with the CAA, could be more in number in the districts, including Rampur, Ghaziabad, Shahjahanpur, Lucknow and some others.

''The list will be sent to the union home ministry,'' the official added.

Sources said that the state government will also inform the centre about the ''illegal Muslim migrants'' for their ultimate deportation to their countries of origin.

Different parts of UP had witnessed large scale violence last month during the protests against the CAA. At least 20 people, mostly youngsters, were killed allegedly in police firing and many others were injured. The state government had denied the charge. 

Alleged police excesses during and after the protests triggered a nationwide outrage with several rights organisations and activists slamming the BJP government and demanding a high-level probe into the allegations.
