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.

Mathura, Mar 2: Union Minister of state Sadhvi Niranjan Jyoti on Sunday said after the Citizenship (Amendment) Act (CAA), the Centre might bring a population control law.

Jyoti claimed that she has already spoken to Prime Minister Narendra Modi in this regard.

She said she believes that this issue is under the prime minister's consideration and he himself has discussed the importance of bringing this law.

Jyoti arrived here on Sunday to attend a tribute meeting held at Swami Vamdev Jyotirmath in Chaitanya Vihar. Unnao MP Sakshi Maharaj was also present at the event.

"There was a time when abrogation of Article 370 in Jammu and Kashmir was impossible. It was feared that if such thing happens, there will be bloodbath. No one will be hold the national flag in Kashmir. But this government can bring any law in favour of the nation," Jyoti said.

"Now, everyone believes that if Article 370 can be removed...Prime Minister Narendra Modi can bring any law which is important for the country," she added.

New Delhi, Feb 23: Dreaded underworld don Ravi Pujari, operating from overseas, has been reportedly arrested in South Africa and efforts are on for his deportation to India.

Pujari, who parted ways with underworld don Chhota Rajan, had jumped bail from Senegal, last year and had escaped to South Africa, where he was involved in big-time drug trafficking and extortion racket.

Sources in Indian Intelligence said that Ravi Pujari, who was hiding with a false identity of Anthony Fernandes, a Burkina Faso passport holder, was located in a remote village in South Africa.

On a tip-off from Indian external intelligence agency, the Senegal police air dashed South Africa last week. Pujari, 52, wanted in over 200 cases of heinous crimes, including murder and extortion, was detained with the help of South African agencies.

Sources in Mumbai Police said that Pujari's arrest has not yet been confirmed officially but Ministry of External Affairs is in touch with its mission in South Africa. An official in MEA refused to speak on the issue. Embassy of Senegal in Vasant Vihar, New Delhi, also did not respond to IANS' queries in connection with Pujari's arrest.

The mafioso first came into news in early 2000 when he started extorting huge amounts from famous Bollywood personalties and builders. He was involved in an attempt to murder case, aimed at killing a prominent lawyer of Mumbai.tip-off

Pujari's wife Padma and three children also fled India and some of them hold Burkina Faso passport. His son who was recently married in Australia reportedly holds an Australian passport.

Earlier last year Ravi Pujari, living under the identity of Anthony had jumped bailed from a Senegal court through fraudulent means. IANS had accessed the don's new passport. Pujari now goes under the name of Anthony Fernandes and is a citizen of Burkina Faso, a West African country, his date of birth is shown as 25.1.1961.

Pujari, a movie junkie influenced by Amitabh Bachchan's portrayal as Anthony Gonsalves in 'Amar Akbar Anthony' was using the name, Anthony Fernandes. This passport was issued on 10.7.2013 and is valid till 8.7.2023. The passport showed his profession as Agent Commercial which means that he is designated as a businessman running a chain of restaurants Namaste India in Senegal, Burkina Faso and neighbouring countries.

Pujari's lawyers in Senegal had argued in the court citing that he is Anthony Fernandes, a businessman from Burkina Faso as mentioned in his passport and not a fugitive as claimed by the Indian Government.

Clearly indicating a collision between top government functionaries of Burkina Faso and Pujari in which an influential Indian businessman, who is his partner in a restaurant chain, may have played the role of a conduit.

Mumbai, Mar 9: India's Yes Bank will not be merged with State Bank of India, which is set to infuse funds in the beleaguered lender, the newly appointed administrator leading the rescue plan said in a television interview on Monday.

"There is absolutely no question of a merger," Prashant Kumar, the administrator, told the CNBC TV18 channel.

The Reserve Bank of India (RBI) on Thursday took control of Yes Bank, after the lender - which is laden with bad debts - failed to raise the capital it needs to stay above mandated regulatory requirements.

Placing Yes Bank under a 30-day moratorium, the central bank imposed limits on withdrawals to protect depositors and said it would work on a revival plan. The move spooked depositors, who rushed to withdraw funds from the bank.

Kumar, a former finance chief at SBI, assured depositors their money was safe and that the moratorium on Yes Bank might be lifted much before the deadline on April 3 and normal banking operations might resume as early as Friday.

He also mentioned that the withdrawal limit of Yes Bank may be removed by March 15, 2020.

SBI Chairman Rajnish Kumar said on Saturday the state-run bank would need to invest up to 24.5 billion rupees ($331 million) to buy a 49% stake in Yes Bank as part of the initial phase of the rescue deal, adding that the survival of troubled lender was a "must".
