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 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.

Ahmedabad, Feb 29: The presence of two feral pigeons onboard a GoAir flight at the airport in Ahmedabad in Gujarat created a flutter among the amused passengers, even though the avian surprise did not lead to any untoward incident or delay in the flight.

The incident took place on Friday when the passengers were boarding the Ahmedabad-Jaipur flight.

"Two pigeons had found their way inside the flight G8 702 while the passengers were boarding," an airline statement said on Saturday.

"The crew immediately shooed away the birds. The flight took off at its scheduled time at 5 p.m.," it added.

New Delhi, Feb 14: Senior Congress leader P Chidambaram on Thursday said there must be a "huge mass movement" if any Muslim was sent to detention camps in case the Supreme Court upheld the validity of the Citizenship Amendment Act (CAA).

Speaking at the JNU campus, the former Union minister said the CAA was an outcome of the "NRC fiasco" in Assam that left 19 lakh people out of the document.

The CAA was brought to accommodate the 12 lakh Hindus among the 19 lakh people who could not be included in the National Register of Citizens (NRC) in Assam, he claimed.

Replying to a question by a student on the best course of action if the CAA was upheld by the apex court, Chidambaram said, "When they touch the excluded...they will only be Muslims, to identify and throw them out, declare them stateless, there must be a huge mass movement, resisting any Muslim being thrown out or kept in detention camps."

He also said the Congress believed that the CAA must be repealed and there should be a political struggle so that the National Population Register (NPR) was pushed beyond 2024.

Claiming that the NRC, CAA and NPR were "closely connected" to each other, Chidambaram said, "The CAA was brought due to the NRC fiasco in Assam and the opposition to the CAA gave way to the NPR."

He asserted that the Congress was protesting against the CAA and the NRC across the country, but had consciously avoided going to Shaheen Bagh, as in that case, the ruling Bharatiya Janata Party (BJP) would brand the demonstration against the amended citizenship law as a "political" one.

"See, we are not going to Shaheen Bagh because that would be falling into the BJP's trap. If we go there, they (BJP) will say it is political," the senior Congress leader said.

Slamming the CAA and the NRC as instruments undermining the very basis of the formation of India, he said the country, instead, needed a "broad law" on refugees.

Speaking at an event against the NRC, CAA and NPR hosted by the Congress's student wing, NSUI, at the Jawaharlal Nehru University (JNU), Chidambaram accused the BJP of spreading lies against Opposition parties.

"The BJP says the Congress, the Left and other liberal parties are against citizenship to persecuted Hindus, Sikhs from Pakistan, Bangladesh. But we are not against those included, our opposition is against exclusion," he said.

Questioning the rationale behind the CAA, the former finance minister said it excluded people on the basis of religion.

"Why only three countries, what about other neighbouring countries — Nepal, Bhutan, China? What about others treated much worse? The Ahmadiyas and Shias of Pakistan, the Rohingyas of Myanmar, Tamil Hindus are equally persecuted, why are they left out?" he questioned.

Chidambaram also said the CAA did not cover persecution based on language, political ideology and economic deprivation.

Slamming the NRC, he wondered which country would accept those left out of the document.

"Which country is going to accept them? How will they go? Where will you send them? (Home Minister) Amit Shah saying that they are termites and he will throw them out by 2024 is talking through his hat," the senior Congress leader said.
