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.

Munbai/New Delhi, May 4: India expects bad debts at its banks could double after the coronavirus crisis brought the economy to a sudden halt, a senior government official and four top bankers said.

Indian banks are already grappling with 9.35 trillion rupees ($123 billion) of soured loans, which was equivalent to about 9.1% of their total assets at the end of September 2019.

"There is a considered view in the government that bank non-performing assets (NPAs) could double to 18-20% by the end of the fiscal year, as 20-25% of outstanding loans face a risk of default," the official with direct knowledge of the matter said.

A fresh surge in bad debt could hit credit growth and delay India's recovery from the coronavirus pandemic.

"These are unprecedented times and the way it's going we can expect banks to report double the amount of NPAs from what we've seen in earlier quarters," the finance head of a top public sector bank told Reuters.

The official and bankers declined to be named as they were not officially authorized to discuss the matter with media.

India's finance ministry declined to comment, while the Reserve Bank of India and Indian Banks' Association, the main industry body, did not immediately respond to emails seeking comment.

The Indian economy has ground to a standstill amid a 40-day nationwide lockdown to rein in the spread of coronavirus cases.

The lockdown has now been extended by a further two weeks, but the government has begun to ease some restrictions in districts that are relatively unscathed by the virus.

India has so far recorded nearly 40,000 cases of the coronavirus and more than 1,300 deaths from COVID-19, the respiratory disease caused by the coronavirus.

'RIDING THE TIGER'

Bankers fear it is unlikely that the economy will fully open up before June or July, and loans, especially those to small- and medium-sized businesses which constitute nearly 20% of overall credit, may be among the worst affected.

This is because all 10 of India's largest cities fall in high-risk red zones, where restrictions will remain stringent.

A report by Axis Bank said that these red zones, which contribute significantly to India's economy, account for roughly 83% of the overall loans made by its banks as of December.

One of the sources, an executive director of a public sector bank, said that economic growth had been sluggish and risks had been heightened, even ahead of the coronavirus crisis.

"Now we have this Black Swan event which means without any meaningful government stimulus, the economy will be in tatters for several more quarters," he said.

McKinsey & Co last month forecast India's economy could contract by around 20% in the three months through June, if the lockdown was extended to mid-May, and growth in the fiscal year was likely to fall 2% to 3%.

Bankers say the only way to stem the steep rise in bad loans is if the RBI significantly relaxes bad asset recognition rules.

Banks have asked the central bank to allow all loans to be categorized as NPAs only after 180 days, which is double the current 90-day window.

"The lockdown is like riding the tiger, once we get off it we'll be in a difficult position," a senior private sector banker said.

New Delhi, Mar 19: Former Chief Justice of India Ranjan Gogoi took oath as Rajya Sabha MP on Thursday.

Gogoi's wife Rupanjali Gogoi, daughter, and son in law were also present in Parliament.

Congress staged a walkout from the Rajya Sabha over Gogoi's membership to the House.

Meanwhile, Union Minister Ravishankar Prasad welcomed Gogoi in the Rajya Sabha.

President Ram Nath Kovind had nominated the former CJI to the Rajya Sabha on March 16.

Gogoi served as the 46th Chief Justice of India from October 3, 2018, to November 17, 2019.

On November 9, 2019, a five-judge Bench headed by him had delivered the verdict in the long-pending Ramjanmabhoomi case.

People lost trust in Judiciary because of such horrible criminals.

 

He betrayed the whole nation. Unless he is booked, the judiciary will not restore the lost faith. 

 

 

The loss may be momentary in nature, It is the promise of the Almighty, He will ensure the justice is served to everyone.
