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.

Jul 2: Democratic presidential candidate and former US vice-president Joe Biden has said that if he wins the November elections, strengthening the relationship with India which is America’s "natural partner", will be a high priority for his administration.

"India needs to be a partner in the region for our safety's sake and quite frankly for theirs," he said in response to a question on India-US relationship during a virtual fundraiser event on Wednesday.

At the fundraiser hosted by Chairman and CEO of Beacon Capital Partners Alan Leventhal, the former vice president said that India and the United States were natural partners.

"That partnership, a strategic partnership, is necessary and important in our security," Biden said when asked by an attendee whether India is critical to the US' national security.

Referring to his eight years as the vice president, he said, "In our administration, I was proud to play a role more than a decade ago in securing Congressional approval for the US-India Civil Nuclear Agreement, which is a big deal".

"Helping open the door to great progress in our relationship and strengthening our strategic partnership with India was a high priority in the Obama-Biden administration and will be a high priority if I'm elected president,” Biden said.

Both as the vice president and a senator from Delaware, he was a big supporter of India-US relationship.

About the November polls, Biden said that the character of the country is on the ballot. The upcoming election is the most important poll of a lifetime and that the country is currently engaged in a battle for its soul, he claimed.

Biden also slammed President Donald Trump and his administration over the handling of the coronavirus pandemic.

"Trump ignored warnings from the very beginning, refused to prepare and failed to protect the country. Not just now but throughout his presidency, undermining the very core pillars of ours, what I would argue, moral and economic strength.

"I really do believe that our country is crying out for leadership and maybe even more important, some healing. Today, we have an enormous opportunity not only to rebuild but to build back better than before. To build a better future. That's what America does," he added.

Jan 6: India’s Finance Ministry has delivered a challenge to its revenue collectors: meet tax targets despite $20 billion of corporate tax cuts.

Through a video conference on Dec. 16, officials were exhorted to meet the direct tax mop-up target of 13.4 trillion rupees ($187 billion), a government official told reporters. Collection in the eight months to November grew at 5% from a year earlier, against the desired 17%.

The missive shows Prime Minister Narendra Modi’s urgent need to buoy public finances in a slowing economy where April-November tax collections were half the amount budgeted. Authorities withheld some payments to states and have capped ministries’ expenditure as the fiscal deficit ballooned beyond the target.

The government’s efforts to maintain its deficit goal goes against advice from some quarters, including central bank Governor Shaktikanta Das, who urged more spending to spur economic growth.

It’s uncertain though how much room Modi’s administration has to boost expenditure, given that it may already be borrowing as much as 540 billion rupees through state-run companies, a figure that isn’t reflected on the federal balance sheet. Uncertainty about public finances pushed up sovereign yields in November and December, compelling Das to announce unconventional policies to keep costs in check.

“This is not a time to conceal the fiscal deficit by off-budget borrowing or deferring payments,” said Indira Rajaraman, an economist and a former member of the Reserve Bank of India’s board. “If they were to stick to the target, that would be catastrophic because there is so much pump-priming that is needed right now.”

GDP grew 4.5% in the quarter ended September, the slowest pace in more than six years as both consumption and investments cooled in Asia’s third-largest economy. Only government spending supported the expansion, piling pressure on Modi to keep stimulating.

S&P Global Ratings warned in December it may downgrade India’s sovereign ratings if economic growth doesn’t recover. Government support seems to be waning now, with ministries asked to cap spending in the final quarter of the financial year at 25% of the amount budgeted rather than 33% allowed earlier. This new rule will hamstring sectors including agriculture, aviation and coal, where not even half of annual targets have been disbursed.

As the federal government runs short of money, it’s been delaying payouts to state administrations.

Private hospitals have threatened to suspend cash-less services to government employees over non-payment of dues, while a builder informed the stock exchange about delayed rental payments from no less than the tax office itself.

India is considering a litigation-settlement plan that will allow companies to exit lingering tax disputes by paying a portion of the money demanded by the government, the Economic Times newspaper reported Saturday.

The move will help improve the ease of doing business besides unlocking a part of the almost 8 trillion rupees ($111 billion) caught up in these disputes. The step, which is being considered as part of the annual budget, could also bridge India’s fiscal gap.

Finance Minister Nirmala Sitharaman has refused to comment on the deficit goal before the official budget presentation due Feb. 1.

A deviation from target, if any, “will need to be balanced with a credible consolidation plan further-out,” said Radhika Rao, an economist at DBS Group Holdings Ltd. in Singapore.

Washington, Feb 12: US President Donald Trump said on Tuesday he would sign a trade deal with Prime Minister Narendra Modi if 'it was the right one'.

The two countries have been trying to reach a limited trade pact with lower tariffs, but talks have run into problems over issues with data privacy and e-commerce controls.

Trump further said that he is looking forward to his visit to India later this month where millions of people would welcome him. "He (Modi) is a great gentleman and I look forward to going to India. So, we'll be going at the end of the month," Trump told reporters in his Oval Office, a day after the White House announced dates of his anticipated India trip.

Responding to a question, the president indicated that he is willing to sign a trade deal with India if it is the right one. "They (Indians) want to do something and we'll see... if we can make the right deal, (we) will do it," said Trump, a fortnight ahead of his visit to the country as the 45th US president.

India's new Ambassador to the US, Taranjit Singh Sandhu told PTI that Trump's forthcoming visit is a "reflection of the strong personal rapport" between Trump and Modi. "It also demonstrates their strong desire to take the relationship to new heights," said Sandhu, who had presented his credentials to Trump in Oval Office last week.

Over the last three years, Trump and Modi have developed a personal friendship and in 2019, the duo met four times including their joint address before a strong 50,000 crowd of Indian Americans in Houston.

This year, they have spoken over the phone on two occasions, including the one over the weekend. "Just spoke with Prime Minister Modi," Trump told reporters on Tuesday in response to a question on his India visit.

Excited to travel to India later this month, said Trump referring to his conversation with Modi during which the prime minister apparently told him about the hundreds and thousands of Indians who would be there to welcome him in Ahmedabad.

Trump jokingly told reporters that now he will "not feel good" about the size of the crowd that he addresses in the US which is usually between 40,000 to 50,000. "He (Modi) said we will have millions and millions of people. My only problem is that last night we probably had 40 or 50,000 people... I'm not going to feel so good... There will be five to seven million people just from the airport to the new stadium (in Ahmedabad)," Trump said.

"And you know (it) is the largest stadium in the world. He's (Modi) building it now. It's almost complete and it's the largest in the world," Trump said. The two leaders are expected to joint address a massive public rally at the newly build Motera Stadium in Ahmedabad.

Being built at an estimated cost of USD 100 million, the Motera Stadium with a seating capacity of 100,000 spectators will be the world's largest cricket stadium overtaking the Melbourne Cricket Ground in Australia.
