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.

Mumbai, Jan 7: Facing criticism from social media and political quarters for holding a 'Free Kashmir' poster during a protest against violence at Jawaharlal Nehru University (JNU), Mehak Prabhu, a Mumbai-based storyteller, on Tuesday clarified that she meant to highlight the restrictions imposed in Jammu and Kashmir and wishes to see peace in the region, adding she had no other motive behind her actions.

"At around 7 pm yesterday, I reached where the protest was happening at the Gateway of India. Like anybody else who believes in democracy, I also joined that protest. We were standing for justice to the JNU students," Prabhu said in a video posted on Facebook.

"I saw a bunch of people who were painting placards on every issue like NRC, CAA and for JNU students. There was a placard lying on the side which said 'Free Kashmir'. The first thing which came to my mind when I saw that placard was about the basic constitutional rights of Kashmiris," she said.

Prabhu also said that she was not a Kashmiri and was brought up in Mumbai. She outlined that she was standing with a flower in her hand and asserted that the entire matter was "completely blown out of proportion".

"I was quietly standing with a flower in my hand. This means we need to make peace together. That was my only intention in holding that placard. The narrative that has been put out is absolutely wrong," she said, describing the reactions to the matter was "crazy".

The Mumbai-based storyteller underlined that the incident is scary and urged the people to spread the words of what she said and not hatred.

"The way it has gone, it is very scary. I am a simple person. As a woman, it is very scary for my safety right now. Spread this side of my story and let's stop it here. Let us not spread the hate. It has happened to me, it can happen to anyone. We should not live in fear," Prabhu further said.

Lucknow, Jun 20: A media body on Saturday described as "an act of intimidation" the filing of an FIR in Uttar Pradesh against a journalist over a report on the impact of the lockdown on a village, saying it was part of an "established pattern" of harassment of independent scribes.

In a statement, the Media Foundation put on record its strong protest over the FIR filed by the Uttar Pradesh government against Supriya Sharma, executive editor of news portal Scroll.in.

The case was filed against Sharma for allegedly misrepresenting facts in a report on the impact of the lockdown in a village adopted by Prime Minister Narendra Modi, police sources had said on Thursday.

The FIR against Sharma and the Scroll editor-in-chief is an "an act of intimidation and a case of abuse of process", intended to discourage honest and critical reporting, the Media Foundation said.

The Media Foundation was started in 1979 with the aim of upholding freedom of speech, expression and information.

The FIR against Sharma is only the latest instance of similar coercive actions against professional journalists, part of "an established pattern of harassment and humiliation of independent journalists", it said,

"It is an unacceptable encroachment on press freedom," said the foundation, whose chairperson is veteran journalist Harish Khare.

The Media Foundation called upon the judiciary, and central and state governments to uphold the spirit of freedom of speech and expression as guaranteed in the Constitution.

Jaipur, Jul 14: In a show of strength, Deputy Chief Minister Sachin Pilot-led Rajasthan Congress camp on Monday released a video showing at least 16 MLAs sitting together.

This comes hours after the Congress held a legislature party meeting. Party leaders said 106 of 122 MLAs attended, a claim contested by the Pilot camp.

The 10-second video was shared late at night on Pilot's official WhatsApp group.

In the video, at least 16 MLAs are seen sitting together in a close circle. Pilot is not seen in the video.

Six other people can be seen in the video but they could not be identified.

Some of the MLAs seen in the video are Indraraj Gurjar, Mukesh Bhakar, Harish Meena.

Tourism Minister Vishvendra Singh tweeted the video with the caption "Family".

Ladnun MLA Mukesh Bhakar tweeted, "...Loyalty in Congress means Ashok Gehlot's slavery. That is not acceptable to us."

Pilot has been upset since he was denied the Rajasthan chief minister's post after the December 2018 assembly elections.

On Sunday, he claimed to have the backing of 30 Congress MLAs and "some independents".

Those close to him disputed Gehlot's claim that his government had a majority, and said this is proven in the assembly and not at the CM's house.

Sources close to him have also ruled out the possibility of Pilot joining the BJP.

In the 200-member Rajasthan Assembly, the Congress has 107 MLAs and the BJP 72. In the past, the ruling party has claimed the support of 13 independents, two MLAs each from the CPM and the Bharatiya Tribal Party, and one from the Rashtriya Lok Dal.
