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.

The US space agency has thrown open a challenge to win over Rs 26 lakh, calling the global community to send novel design concepts for compact toilets that can operate in both microgravity and lunar gravity.

NASA is preparing for return to the Moon and innumerable activities to equip, shelter, and otherwise support future astronauts are underway.

The astronauts will be eating and drinking, and subsequently urinating and defecating in microgravity and lunar gravity.

NASA said that while astronauts are in the cabin and out of their spacesuits, they will need a toilet that has all the same capabilities as ones here on Earth.

The public designs for space toilet may be adapted for use in the Artemis lunar landers that take humans back to the Moon.

"Although space toilets already exist and are in use (at the International Space Station, for example), they are designed for microgravity only," the US space agency said in a statement.

NASA's Human Landing System Programme is looking for a next-generation device that is smaller, more efficient, and capable of working in both microgravity and lunar gravity.

The new NASA challenge includes a Technical category and Junior category and the last date to send designs is August 17.

NASA's Artemis Moon mission will land the first woman and next man on the lunar surface by 2024.

The Artemis programme is part of America's broader Moon to Mars exploration approach, in which astronauts will explore the Moon and experience gained there to enable humanity's next giant leap, sending humans to Mars.

Jan 31: Twenty-three children aged between six months and 15 years, who had been taken hostage by a murder accused after inviting them to his daughter's birthday party, were rescued late on Thursday night after police killed their captor in a village here.

The hostage drama began at Kasaria village in the afternoon and continued for about eight hours.

"The accused was killed and there were about 23 children who were rescued safely," Additional Chief Secretary (Home) Awanish Awasthi told reporters at a hurriedly called press conference at 1.20 am.

"The accused had invited the children for the birthday party of his daughter and held them hostage. It started about 5.45 pm on January 30 and continued for about eight hours," Director General of Police (DGP) O P Singh said, adding that in the entire operation they had tried to "engage" the accused and were successful.

He said the accused, identified as Subhash Batham, had initially released a six-month-old girl by handing her over to his neighbour from a balcony.

Eyewitnesses said a restive crowd gathered outside the house where the children were kept with some women wailing and praying for their safe release.

The crowd broke open the door of the house to rescue the children, they said.

As the accused opened fire, the police retaliated killing him on the spot.

In the exchange of fire, the captor's wife was injured, but none of the children suffered any injury.

A man and two policemen also suffered bullet injuries.

The motive of the accused was not known immediately.

Chief Minister Yogi Adityanath monitored the situation in Farrukhabad, which is nearly 200 km from state capital Lucknow.

"The CM as soon as he got to know about the incident called a meeting of the crisis management group and personally monitored the situation and ensured children are rescued safely," Awasthi said.

Earlier, a team of NSG (National Security Guard) commandos had taken a special aircraft to reach Farukhabad, a senior security official in Delhi said.

Police said Batham, a murder accused, seemed to be mentally unstable.

Inspector-General of Police, Kanpur Range, Mohit Agarwal, said, "The man called the children for a birthday party and held them hostage in the basement of the house. He fired six shots from inside the building."

Batham initially wanted to talk to the local MLA, but refused to speak to the leader when he arrived, Agarwal said.
