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, Jan 22: Defence Minister Rajnath Singh on Wednesday said Indian values consider all religions equal, and that is why the country is secular and never became a theocratic state like Pakistan.

Speaking at the NCC Republic Day Camp in Delhi, Singh said: "We (India) said we would not discriminate among religions. Why did we do that? Our neighbouring country has declared that their state has a religion. They have declared themselves a theocratic state. We didn't declare so."

"Even America is a theocratic country. India is not a theocratic country. Why? Because our saints and seers did not just consider the people living within our borders as part of the family, but called everyone living in the world as one family," the minister said.

Singh underlined that India had never declared its religion would be Hindu, Sikh or Buddhist and people of all religions could live here.

"They gave the slogan of 'Vasudev Kutumbakam' -- the whole world is one family. This message has gone to the whole world from here only," he added.

Very thoughtful and eye-catching statement by Defense Minister, Rajnath Singh.

Sir, I kindly request you to convey this beautiful message to your Party’s comrades, who are deprived of this dosage for long times and are badly need of this.  

Also, for those from your Party, who are, time and again, spitting the venomous rhetoric against Dalits, Muslims, Christians and others alike.

Yashwant Sinhaji is now doing a wonderful job in this regard.

You will also follow his suit for sure in the days to come; that’s what your honest statement indicates.

New Delhi, Feb 3: In the third such incident inside of a week, two unidentified persons opened fire outside Gate No. 5 of Jamia Millia Islamia on Sunday night, the Jamia Coordination Committee (JCC) said.

A statement issued by the committee, a group comprising students and alumni of the university formed to protest against the Citizenship Amendment Act, said the attackers were on a red Rcooty.

No one was injured in the attack. One of the miscreants was wearing a red jacket, the statement said.

"Firing has taken place at Gate No.5 of Jamia Millia Islamia right now by two unidentified persons. As per report, one of them was wearing a red jacket and driving a red Scooty having vehicle no. 1532 or 1534," the statement said.

Police said they were verifying the JCC's claims.

Asim Mohammed Khan, former Congress MLA from Okhla, said the incident occurred around 11.30 pm. "We heard the gunshot. That is when we stepped out to see and the two men left on a Scooty," a student said.

"We have taken down the vehicle number and called police," he added.

This is the third firing incident in the Jamia Nagar area in a week.

On Thursday, a minor fired at anti-CAA protesters marching towards Rajghat, injuring a student.

Two days later, a 25-year-old fired two rounds in air in Shaheen Bagh in Jamia Nagar. No one was hurt in the incident.

The incident on Sunday night triggered panic in the area. A police vehicle had reached the spot after the incident but was chased away by angry students.

Hundreds of students and locals gathered outside the university.

Many raised slogans against the Delhi Police. They also staged a dharna outside the Jamia Nagar police station.

Shezad Ahmed, a JMI student and resident of Zakir Nagar, said they were not even allowed to protest peacefully.

"We are not going to be deterred by such incidents. We will continue with our protest," he added.
