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.

New Delhi, Jan 1: Prevention of Money Laundering Act (PMLA) court in Mumbai has allowed banks that lent money to embattled liquor tycoon Vijay Mallya to utilize seized assets, news agency reported today quoting sources from the Enforcement Directorate (ED). The court also said all parties affected by the order can appeal at the Bombay High Court till January 18.

Last month, a consortium of Indian banks petitioned a London court for ex-billionaire Vijay Mallya to be declared bankrupt over ₹9,000 crore in unpaid debts. It comes as Mallya, who founded the now defunct Kingfisher Airlines Ltd, faces extradition to his home country of India.

Mallya had fled India in March 2016 and has been living in the United Kingdom since then. The 64-year-old former Kingfisher Airlines is fighting extradition to India in relation of fraud and money laundering allegations arising out of the debt acquired from the banks.

Mallya remains on bail pending the UK High Court appeal hearing in the extradition proceedings brought by India in relation to fraud and money laundering charges amounting to ₹9,000 crores. He had been arrested on an extradition warrant back in April 2017 and has been fighting his extradition in the UK courts since then.

He was granted permission to appeal against his extradition order, which is scheduled in the Royal Courts of Justice in London for February.

Mar 10: Indian energy tycoon Mukesh Ambani is no longer Asia’s richest man, relinquishing the title to Jack Ma after oil prices collapsed along with global stocks.

The rout, exacerbated by mounting fears that the spread of the novel coronavirus will thrust the world into a recession, erased $5.8 billion from Ambani’s net worth on Monday and pushed him to No. 2 on the list of Asia’s richest people, according to the Bloomberg Billionaires Index. Ma, the Alibaba Group Holding Ltd. founder who relinquished the No. 1 ranking in mid-2018, is back on top with a $44.5 billion fortune, about $2.6 billion more than Ambani.

Oil plunged the most in 29 years on Monday as Saudi Arabia and Russia vowed to pump more in a struggle for market share. The slump comes just as the coronavirus is spurring the first decline in demand in more than a decade. That raises questions about whether Ambani’s flagship Reliance Industries Ltd. will be able to cut net debt to zero by early 2021, as he has pledged. The plan hinges on a proposal to sell a stake in the group’s oil and petrochemicals division to Saudi Arabian Oil Co., the world’s biggest crude producer.

While the coronavirus has curtailed some of tech giant Alibaba’s businesses, the damage has been mitigated by increased demand for its cloud computing services and mobile apps.

Reliance Industries, by comparison, has no such silver lining. The Indian conglomerate’s shares plunged 12% on Monday, the most since 2009, extending this year’s decline to 26%. Alibaba’s American depositary receipts have slipped 6.8% so far in 2020.

Ma reclaims crown after Reliance shares were pummeled in 2020.

Few of the world’s billionaires fared well in Monday’s collapse as the S&P 500 Index and Dow Jones Industrial Average each plunged more than 7.5%, the most since the 2008 financial crisis, threatening to end the longest bull market in history. But no one did worse than those whose fortunes are underpinned by oil. Wildcatter Harold Hamm’s fortune was cut almost in half to $2.4 billion and fellow oil magnate Jeff Hildebrand lost $3 billion, bumping both from Bloomberg’s 500-member wealth ranking.

In a pivot toward new businesses such as telecommunications, technology and retail, Ambani’s Reliance Industries has piled on billions of dollars of debt over the years.

It spent almost $50 billion -- most of it funded by borrowings -- to build Reliance Jio Infocomm Ltd., which became India’s No. 1 wireless carrier within about three years of its debut. As the mobile venture took off, Ambani also unveiled plans for an e-commerce empire to rival Amazon.com Inc. in India.

Addressing concerns over the liabilities, Ambani pledged in August to cut the group’s net debt to zero from about $21 billion as of last March. The Aramco deal is crucial to that plan for which Reliance Industries has valued its oil-to-chemicals division at $75 billion including debt, implying a $15 billion valuation for the 20% stake that’s for sale.

Signs of a potential delay to that deal unnerved some investors, hammering the stock since it touched a record high on Dec. 19.

Reliance Industries expected the Aramco transaction to be completed by March, but people familiar with the matter said in February that talks were still ongoing to bridge differences between the two parties over the deal’s structure.

Adding to the uncertainty, Indian Prime Minister Narendra Modi’s administration has petitioned a court to halt the proposed stake sale, threatening a key source of funds needed to pare net debt.

But Ambani, 62, may soon bounce back from the setback, said Harish H.V., managing partner at ECube Investment Advisors in Bengaluru, India.

“The game isn’t over,” he said. “Ambani has successfully built a robust business model which would keep him in the game. Moreover, his telecom business will start yielding results in coming years.”
