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, Feb 2: The Congress on Sunday released its manifesto for Delhi polls, promising to implement unemployment allowance of Rs 5,000-7,500 per month and cashback schemes for water and power consumers, if voted to power.

Presenting the manifesto, Delhi Congress chief Subhash Chopra said the party will provide free power up to 300 unit per month.

The manifesto also committed to spend 25 per cent budget each year on fighting pollution and improving transport facilities.

An unemployment allowance of Rs 5,000 for graduates and Rs 7,500 for post graduates per month will be provided under the Yuva Swabhiman Yojna, he said.

The Congress will launch flagship cashback schemes for power and water supply to benefit consumers saving these resources. The party, if voted to power, will open 100 Indira Canteens to provide subsidised meals at Rs 15, Chopra said.

The Congress will challenge the Citizenship Amendment Act (CAA) in the Supreme Court and demand the Centre to withdraw the law. The party will also not implement the National Register of Citizens (NRC) and the existing form of the National Population Register (NPR), if voted to power in Delhi.

New Delhi, Feb 24: The shared values between India and the US are "discrimination, bigotry, and hostility towards refugees and asylum seekers", Amnesty International USA said in a joint statement with Amnesty International India ahead of US President Donald Trump's visit to India on Monday.

Trump, accompanied by his wife Melania, daughter Ivanka and son-in-law Jared Kushner as well as senior officials of his administration, landed in Ahmedabad on the first leg of his two-day visit to India.

"Anti-Muslim sentiment permeates the policies of both U.S. and Indian leaders. For decades, the U.S.-India relationship was anchored by claims of shared values of human rights and human dignity. Now, those shared values are discrimination, bigotry, and hostility towards refugees and asylum seekers,” Margaret Huang, Amnesty International USA’s executive director, was quoted as saying in the statement.

It was a reference to the anti-CAA protests in India, the internet lockdown in Jammu and Kashmir and the Muslim ban expansion by President Trump affecting Nigeria, Eritrea, Myanmar, Kyrgyzstan, Sudan and Tanzania, the statement said.

It added that Amnesty International USA’s researchers travelled to Lebanon and Jordan to conduct nearly 50 interviews with refugees that as a result of the previous version of the ban have been stranded in countries where they face restrictive policies, increasingly hostile environments, and lack the same rights as permanent residents or citizens.

The statement also came down hard on the Indian government, hitting out at the Citizenship (Amendment) Act (CAA) 2019 and saying it legitimises discrimination based on religious grounds.

It criticised statements such as “identify them (the protestors) by their clothes” or “shoot the traitors” by Prime Minister Modi and his party workers. Such remarks "peddled the narrative of fear and division that has fuelled further violence", it said.

“The internet and political lockdown in Kashmir has lasted for months and the enactment of CAA and the crackdown on protests has shown a leadership that is lacking empathy and a willingness to engage. We call on President Trump and Prime Minister Modi to work with the international community and address our concerns in their bilateral conversations,” Avinash Kumar, executive director, Amnesty International India said in the statement.

Mar 16: An investigation into Coffee Day Enterprises Ltd., initiated by its board after the death of founder V.G. Siddhartha, is likely to conclude that at least Rs 2,000 crore is missing from its accounts, according to people familiar with the matter.

The months-long probe following the suicide of Siddhartha in July examined the financial transactions of India’s largest coffee chain and its dealings with dozens of private companies owned by the entrepreneur. The draft report, running more than a hundred pages, points to thousands of rupees that have gone missing, said the people, asking not to be named because the details aren’t public. It also details hundreds of transactions between the founder’s listed and personal businesses that were not conducted at arm’s length, they said.

Though the report is in its final stages, the precise details could change before its release, expected as early as this week, the people said. The missing funds could total more than Rs 2500 crore, one person said.

“The investigation report is still a work in progress, and not finalized,” a spokesman for the company said. “The board of directors and the company are unaware of its content at this point of time. Hence it would be premature to speculate on the investigation findings.”

The priority for management and Siddhartha’s family “is to keep the business running in a challenging environment and meet all stakeholder commitments, including 30,000 jobs associated with the group,” the spokesman added.

The disappearance of the 59-year-old founder last year stunned India’s business community. He had last been seen telling his driver he was going for an evening walk along a bridge in southern India; his body was found by local fishermen two days later. A letter delivered to Coffee Day’s board and employees, which appeared to be signed by Siddhartha, described massive debts and complained of pressure from lenders and tax authorities. It claimed he bore sole responsibility for the company’s financial transactions.

The probe began about a month later when the company brought in Ashok Kumar Malhotra, a retired senior official from India’s federal enforcement agency, to investigate. A senior lawyer practicing in India’s top court is assisting, the company said in a regulatory filing at the time.

The publicly traded Coffee Day was supposed to be India’s answer to Starbucks Corp. More than 1,500 of its Café Coffee Day outlets blanketed cities and highways, with affordable options for the country’s aspiring middle classes. The chain’s tagline: “A lot can happen over coffee.”

But the empire has been battered since the founder’s death. Its shares plummeted about 90% and its market value dropped to about $80 million. Trading was suspended in February.

India’s regulators are tracking the situation and may use the company’s final report as part of a deeper dive into its internal affairs, the people said. Coffee Day showed about Rs 2400 crore in cash and cash equivalents on its balance sheet as of March 2019, the most recent figures the company has issued.

After the death of Siddhartha however, the company faced a severe liquidity crunch and had “zero cash in the bank,” according to one of the people. It struggled with day-to-day expenses and paying salaries has been a strain, the person said.

The draft report details personal guarantees by Siddhartha for loans taken by Coffee Day, and his unsecured loans at high interest rates from local money lenders, the people said. It also probes Coffee Day’s defaults to coffee growers and other vendors, they said.

A related issue is that coffee estates owned by Siddhartha and several employees had been used as collateral for bank loans. The report found that valuations for properties were inflated to get the loans, one person said.

Investigators have examined several theories about what happened to the company’s money, including whether Coffee Day was manipulating its finances to show cash and profit and whether Siddhartha was taking cash out of the listed company to pay off a large investor to whom he had guaranteed a return, the person said. From the filings of his listed and private companies, the entrepreneur’s loans had totaled more than Rs 10,000 crore, and he had been squeezed by borrowing to repay interest on earlier loans, the person said.

In the letter purportedly from Siddhartha, the entrepreneur said he had tried his best but failed as an entrepreneur. “I am solely responsible for all mistakes,” the letter read. “Every financial transaction is my responsibility. My team, auditors and senior management are totally unaware of all my transactions. The law should hold me and only me accountable, as I have withheld this information from everybody including my family.”

As the report nears release, Coffee Day is finalizing a deal with Blackstone Group Inc. for real estate assets. A large tranche of the payment is due in about a week, one person said.

Coffee Day said it is working to reduce its debt load by divesting non-core enterprises.

“The aim is to save employment and preserve this iconic Indian brand,” the spokesman said.
