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 1: Union Minister Prakash Javadekar launched a scathing attack on the Aam Aadmi Party and the Congress for allegedly inciting violence in Delhi against the Citizenship (Amendment) Act. Mr Javadekar said the violence over the amended citizenship law that broke out in areas like Jamia Nagar, Seelampur and Jama Masjid "cannot be forgiven".

"In Jamia, the Congress' Asib Khan and AAP's Amanatullah Khan delivered inciting speeches. They spread disinformation. The law is to give citizenship to people and not take citizenship away," Mr Javadekar told reporters.

He said the people of India understand the plans of the Congress and the AAP and both parties should apologise.

"We will bring out the truth. The fight is between anarchists and those who oppose them. Our agenda would be wholesome development of Delhi. The AAP strangulated municipal corporations' attempt on development. Rs 900 crore was not given. Today, the people of Delhi are surprised that the AAP slept through all these 4.5 years and in the remaining six months they have launched schemes," Mr Javadekar said.

"The work is done by someone else and the credit is taken by a different individual," the Union Minister said, referring to allegations that the government led by Chief Minister Arvind Kejriwal took credit for work done by BJP-ruled municipal agencies.

"Who did fogging in dengue season? Our corporations organised an awareness drive against water accumulation and dengue cases went down. During corporation polls, Kejriwal said don't choose BJP as dengue will claim lives. Now he is also claiming credit for decrease in dengue cases because of the work done by these corporations," Mr Javadekar said.

"I am an environment minister. We worked on pollution control. There is no limit to their (AAP's) lies. About unauthorised colonies, the AAP says we have not regularised it. We made a law signed by the President, yet they spread lies," Mr Javadekar said.

The election in Delhi will be held before the end of February.

New Delhi, Jan 4: In more troubles for the former Finance Minister and senior Congress leader P Chidambaram, the Enforcement Directorate (ED) on Friday questioned him for over six hours in its probe into the Air India aircraft deal case, first time since his release from Tihar jail almost a month ago.

A senior ED official told IANS, "We questioned Chidambaram for over six hours today in the ongoing probe into the Air India deal with Airbus."

According to financial probe agency officials, Air India had planned to buy over 111 aircraft from Airbus and Boeing during the erstwhile United Progressive Alliance (UPA) government in 2009. This is the first time the ED has questioned the senior Congress leader in the Air India deal case.

The questioning of Chidambaram came for the first time since his release from the Tihar jail where he spent 106 days in connection with the INX Media money laundering case. He was released from Tihar on December 4 last year after he was granted bail by the Supreme Court. The former finance minister is also being investigated by the ED in a separate money-laundering cases of Aircel-Maxis deal.

An ED official said the contract to buy 43 aircraft from Airbus was finalised by a panel of ministers headed by Chidambaram in 2009. According to the ED, when the proposal to buy 43 aircraft from Airbus was sent to the Cabinet Committee on Security (CCS), there was a condition that the aircraft manufacturer would have to build training facilities and MRO (Maintenance, Repair and Overhaul) centres at a cost of Rs 70,000 crore. But later, when the purchase order was placed, the clause was removed.

The name of another UPA minister, Praful Patel, had also come up in the alleged scam in a charge sheet filed by the ED against corporate lobbyist Deepak Talwar on March 30 last year. Talwar was arrested last year by the ED after he was deported from the UAE.

The ED is probing the Air India-Indian Airlines merger; purchase of 111 aircraft from Boeing and Airbus at Rs 70,000 crore; ceding profitable routes and schedules to private airlines, and opening of training institutes with foreign investment.

New Delhi, Feb 13: The BJP's Amit Shah today said statements like "goli maaro" and "Indo-Pak match" should not have been made by BJP leaders ahead of the Delhi elections.

The BJP may have suffered in the elections because of hate statements made by party leaders, he said, reported news agency Press Trust of India.

The party, he said, had distanced itself from such remarks.
