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.

London, May 14: Fugitive liquor baron Vijay Mallya on Thursday urged the Central government to accept his offer to repay 100 per cent of his loan dues and close the case against him.

While congratulating the Centre for introducing Rs 20 lakh crore relief package to boost the economy amid the coronavirus lockdown, Mallya, lamented that his repeated attempts to pay back his dues have been ignored by the Indian government.

"Congratulations to the Government for a Covid 19 relief package. They can print as much currency as they want BUT should a small contributor like me who offers 100% payback of State-owned Bank loans be constantly ignored? Please take my money unconditionally and close," he tweeted.

Earlier this month, Mallya had sought permission to appeal against a ruling ordering his extradition to India in Britain's highest court the UK Supreme Court.

The application comes two weeks after the High Court in London - the UK's second-highest court - dismissed Mallya's appeal against a lower court ruling that he be sent to India to face charges of defrauding a consortium of Indian banks of more than Rs 9,000 crores relating to the collapse of Kingfisher Airlines in 2012.

Noida, Jan 6: A fire broke out at the ESIC Hospital in Noida on Thursday morning and firefighting was underway, officials said.

The blaze broke out in the basement of the seven-storey hospital building located in Sector 24, a police official said.

Fire tenders were rushed to the spot after the Fire Department was alerted about it around 8 am, the official said.

After that, a search was done to see if anyone was trapped in the building, he said.

The cooling process is now underway.

He said the fire had engulfed the ground, first and second floors of the building, except the basement.

Police said they received information about fire at Kaveri printing press at 2:45 am, when the manager Yogesh called them. The press owners have been identified as Atul and Anuj Goyal, residents of Sukhdev Vihar, they said.

The man who died in the fire has been identified as Phool Dev, from Bihar, who used to work as a help there. Dev went inside the building in the night to sleep before the fire started and died due to suffocation, the fire department official said.

The body has been kept at Lal Bahadur Shastri Hospital and the post-mortem will be done once the family reaches here, police said.

New Delhi, Jan 15: A Delhi court on Wednesday granted bail to Bhim Army chief Chandrashekhar Azad in connection with the Daryaganj violence case.

The court has ordered him not to hold any protest in Delhi till February 16th.

While hearing the case, the Judge had asked Azad's counsel to read out some of his social media posts.

Advocate Mehmood Pracha, representing Azad, had on Tuesday said that the petitioner was sent to jail without any evidence in connection with anti-CAA protests in Delhi's Darya Ganj area last year.

"I think the court's comments should become a precedent for the country. The Public Prosecutor at the behest of police tried to make this a communal issue. We told the court that the government has a problem with Azad because he made the CAA-NPR-NRC an issue for everyone. 
The Court also sought evidence," Pracha told ANI after Delhi's Tis Hazari court deferred the bail plea of Azad till today.

On Wednesday, the court pulled up the Delhi Police for failing to show any evidence against Azad.

Azad was arrested on December 21 last year after he led a march from Jama Masjid against the Citizenship (Amendment) Act. He was sent to judicial custody till January 18 at Tihar jail.

The Bhim Army chief was charged with rioting, unlawful assembly and inciting the mob to indulge in violence after vandalism in Delhi's Daryaganj area.
