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, May 4: No major crowds were seen in the coastal city of Mangaluru today except in front of the liquor shops after the district administration relaxed the lockdown norms for 12 hours a day (between 7am and 7pm).

There was no mad rush of vehicles either on city roads when the relaxed lockdown began. There were fewer people to buy essentials in front of grocery and vegetable shops as they had time till late evening.

There was no let down in the number of police pickets as well as curbs on vehicular movement across the city either. 

The government has allowed sale of liquor in CL2 (standalone wine shops) and CL 11 (MSIL outlets) to mop up revenues when Lockdown-3 commenced from Monday. Compared the other parts of Karnataka, the size of queues in front of liquor shops in Mangaluru were smaller. 

Like other parts of the country, the lockdown was imposed in the coastal district on March 24 to prevent the spread of Covid-19. Prior to that, a curfew was imposed in the district from March 22 midnight. The lockdown did not apply to essential services such as sale of food, groceries, milk, vegetables, fruits, and meat and fish. Gradually the district administration had to intensify the lockdown and allow those shops to remain open only between 7 a.m. and 12 noon. 

With the lockdown relaxation extending till 7 p.m., Mangaluru today witnessed people and private vehicles moving freely in the afternoon for the first time in more than a month. However, only those who had to go for work and do other essential activities were seen on roads. After 7 p.m. movements of all kinds of vehicles will be prohibited. 

The relaxation was to facilitate economic activities that had come to a standstill during the first two phases of lockdown. Mangaluru City Police Commissioner Dr P S Harsha, meanwhile, warned the people against misusing lockdown relaxation and venturing out without any genuine reason.

New Delhi, Mar 16: Due to the coronavirus pandemic, most airlines in the world will be bankrupt by the end of May and only a coordinated government and industry action right now can avoid the catastrophe, said global aviation consultancy firm CAPA in a note on Monday.

"As the impact of the coronavirus and multiple government travel reactions sweep through our world, many airlines have probably already been driven into technical bankruptcy, or are at least substantially in breach of debt covenants," it stated.

Across the world, airlines have announced drastic reduction in their operations in the wake of the coronavirus outbreak. For example, Atlanta-based Delta Air Lines stated on Sunday that it would be grounding 300 aircraft in its fleet and reduce flights by 40 per cent.

The US has suspended all tourist visas for people belonging to the European Union, the UK and Ireland. Similarly, the Indian government has suspended all tourist visas and e-visas granted on or before March 11.

CAPA, in its note on Monday, said, "By the end of May-2020, most airlines in the world will be bankrupt. Coordinated government and industry action is needed - now - if catastrophe is to be avoided."

Cash reserves are running down quickly as fleets are grounded and "what flights there are operate much less than half full", it added.

"Forward bookings are far outweighed by cancellations and each time there is a new government recommendation it is to discourage flying. Demand is drying up in ways that are completely unprecedented. Normality is not yet on the horizon," it said.

India's largest airline IndiGo -- which has around 260 planes in its fleet -- said on Thursday that it has seen a decline of 15-20 per cent in daily bookings in the last few days.

The low-cost carrier had stated that it expects its quarterly earnings to be materially impacted due to such decline.

CAPA said the failure to coordinate the future will result in protectionism and much less competition.

"The alternative does not bear thinking about. An unstructured and nationalistic outcome will not be survival of the fittest.

"It will mostly consist of airlines that are the biggest and the best-supported by their governments. The system will reek of nationalism. And it will not serve the needs of the 21st century world. That is not a prospect that any responsible government should be prepared to contemplate," the consultancy firm said.
