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.

Kathmandu, Jul 14: After staking claim to Indian territories of Lipulekh-Kalapani in  a new controversial map,  Nepal Prime Minister KP Sharma Oli on Monday claimed that Ayodhya, the birthplace of Lord Rama, is in Nepal and Lord Rama was Nepali.

“Although real Ayodhya lies at Thori, city in the west of Birgunj, India has claimed that Lord Rama was born there. Due to these continuous claims, even we have believed that deity Sita got married to Prince Rama of India. However, in reality, Ayodhya is a village lying west of Birgunj,” Oli claimed at an event organised at Prime Minister's residence in Kathmandu.

The Prime Minister also blamed India of cultural encroachment by “creating a fake Ayodhya.”

“Balmiki Ashram is in Nepal and the holy place where King Dashrath had executed the rites to get the son is in Ridi. Dashrath’s son Ram was not an Indian and Ayodhya is also in Nepal,” he claimed.

In an attempt to save self from criticism, Oli questioned how Lord Rama could come to Janakpur to marry Sita when there were "no means" of communication. He further said that it to be impossible for Lord Rama to come to Janakpur from present Ayodhya that lies in India.

“Janakpur lies here and Ayodhya there and there is talk of marriage. There was neither telephone nor mobile then how could he know about Janakpur,” Oli said.

New Delhi, Mar 6: Union Finance Minister Nirmala Sitharaman on Friday will move the Insolvency and Bankruptcy Code (Second Amendment) Bill, 2019 for consideration and passing in Lok Sabha.

In December last year, the Union Cabinet had approved a proposal to promulgate an ordinance to amend the Insolvency and Bankruptcy Code (IBC) 2016.

The amendments will remove certain ambiguities in the IBC 2016 and ensure smooth implementation of the code, an official statement said.

The move is aimed at easing the insolvency resolution process and promoting the ease of doing business. Aimed at streamlining of the insolvency resolution process, the amendments seek to protect last-mile funding and boost investment in financially-distressed sectors.

Under the amendments, the liability of a corporate debtor for an offence committed before the corporate insolvency resolution process will cease.

The debtor will not be prosecuted for an offence from the date the resolution plan has been approved by the adjudicating authority if a resolution plan results in change in the management or control of the corporate debtor to a person who was not a promoter or in the management or control of the corporate debtor or a related party of such a person.

The amendments are aimed at providing more protection to bidders participating in the recovery proceedings and in turn boosting investor confidence in the country's financial system.

London, Jan 11: Former cricketer Sachin Tendulkar's famous lap around the Wankhede Stadium after the World Cup 2011 win has been nominated in Laureas's list for the most inspiring sporting event in the last twenty years.

The moment featuring Tendulkar has been described as "Carried on the shoulders by a nation".

On his sixth attempt at the World Cup and with India not having won the competition since 1983, Tendulkar finally became a part of the team that lifted the coveted trophy. Carried on the shoulders of the Indian team, he made a lap of honour, shedding tears of joy after the victory was sealed in his home city.

The 2011 World Cup was also the first time, in which a host nation ended up winning the trophy.

Apart from Tendulkar, England's Andrew Flintoff is the only other cricketer to feature in the list. In 2005, England managed to defeat Australia in an Ashes Test, but Flintoff chose to first shake hands with Brett Lee rather than celebrate with his side.

Matthias Steiner (weightlifting), Natalie du Toit (swimming), Sky Brown (skateboarding), Alistair and Jonathan Brownlee (triathlon), Xia Boyu (mountaineering) have been nominated in the list.

Female tennis stars also feature in the list for coming up with an equal play, equal pay campaign. After pressure from Venus Williams and others, Wimbledon announced that female tennis players would receive prize money equal to the men's.

German international footballer Miroslav Klose was playing for Lazio in Italy's Serie A in 2012 against Napoli when he rose for a ball in the early moments of the game.

The ball came spiraling off his hand and skirted into the back of the net and a goal was awarded. While most players would carry on as if nothing had happened, Klose was honest with the referee and admitted that he handled the ball.

As a result, he also finds a place on the list.

The Laureus Sporting Moment Award celebrates the moments where the sport has unified people in the most extraordinary way.

This campaign has shortlisted 20 sporting stories from the last 20 years that have left their mark on the world.

The winner will be decided on the basis of public voting. It has already started, and the final date to cast the vote is February 16.

Finally, the result will be declared on February 17.
With three knock-out rounds, the top-20 moments will be whittled down to ten then five, with the top-five moments going head-to-head.
