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.

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.

New Delhi, Jan 11: Islamic preacher Zakir Naik has revealed that the Bharatiya Janata Party-led government offered to drop false money-laundering charges against him and provide with a "safe passage to India" in return for his support to the government's move to revoke Article 370 of the Constitution.

In a statement issued by Naik's PR team on Saturday, the Islamic preacher said that he was approached by a representative of the Indian government in September, who offered him the said deal on Kashmir, which he refused.

"Three and a half months before, the Indian officials approached me for a private meeting with a representative of the Indian government. When he came to Putrajaya (a Malaysian city), in the fourth week of September 2019, to meet me, he said that he is coming after personally meeting and under the direct instructions of the Prime Minister of India Narendra Modi and the Home Minister of India Amit Shah," Naik said in a video statement released by his Mumbai-based PR team.

Naik, who has been living in Malaysia for the last three years, is facing charges of inciting communal disharmony and committing unlawful activities in India.

"(The representative) said that he wanted to remove the misconceptions and miscommunications between myself (Naik) and the Indian government, and wants to provide me a safe passage to India," he added. "He (the representative) said that he would like to use my connections to better the relationship between India and the other Muslim countries."

"The meeting lasted for several hours. He told me that he wanted me to support the BJP government when they revoked Article 370 in Kashmir. And I flatly refused," he added.

Naik said that after he refused the offer, he was further asked to not make public statements against the BJP or Prime Minister Narendra Modi.

Facebook on Monday launched a new consumer marketing campaign in India titled 'More Together'. India is the first country in the Asia Pacific region where such a campaign is being rolled out.

It is also the first time that Facebook is rolling out a 'high decibel campaign of this stature in India', the company said in a statement.

It is also the first time that Facebook is rolling out a 'high decibel campaign of this stature in India', the company said in a statement.

"India is at the heart of Facebook and one of our focus areas this year is to tell the exciting story of a service that is deeply embedded in the fabric of India," said Ajit Mohan, Vice President and Managing Director, Facebook India.

The campaign would have multiple campaigns over the next few weeks in eight languages and the one will be set in the context of Holi.

Facebook in 2019 introduced a new company logo to further distinguish the company from the Facebook app.

The company recently announced the appointment of Avinash Pant as the Marketing Director for India operations, to drive the consumer marketing efforts across the family of apps.
