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 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.

Raipur, Mar 13: Calling Jyotiraditya Scindia a "power-hungry" leader, Chhattisgarh Minister and Congress leader TS Singh Deo on Friday said that if someone joins another party to occupy the top position of the state that he should never become a Chief Minister.

When enquired if Deo has any plans to join the BJP in the future, he quickly said that he would never be able to relate himself with the "ideology" of the party.

"People may make claims but I will never join BJP, even if I get 100 lives I will never associate with that ideology. A person who joins BJP for not being able to become Chief Minister should never become a Chief Minister," he said while speaking to media in Raipur.

"A single person does not remain as captain forever, Kapil Dev got his chance when Gavaskar was there. Currently, Virat Kohli is the captain but in T20 there are different captains. Will Kohli join Pakistan's team if he is not made the captain? This is beyond understanding."

On Wednesday, Scindia joined BJP in New Delhi in the presence of party President JP Nadda. He had resigned from Congress a day earlier after meeting Union Home Minister Amit Shah and Prime Minister Narendra Modi.

He will file his nomination for the Rajya Sabha elections on March 13.

Jaipur, Jan 26: Rajasthan on Saturday on Saturday became the third state in the country to pass a resolution urging the Centre to repeal the Citizenship Amendment Act (CAA).

he resolution was passed in the state Assembly amid opposition by the BJP which accused the ruling Congress of pursuing appeasement politics.

It is the second Congress-ruled state to pass such a resolution after Punjab. The Kerala Assembly too had passed such a resolution against the CAA moved jointly by the ruling Left Front alliance and the opposition Congress-led UDF.

The Rajasthan Assembly resolution, passed by voice vote, also asked the Centre to withdraw the new fields of information that have been sought for updation of the National Population Register (NPR) 2020.

"It is evident that the CAA violates the provisions of the Constitution. Therefore, the House resolves to urge upon the government of India to repeal the CAA to avoid any discrimination on the basis of religion in granting citizenship and to ensure equality before law for all religious groups of India," the state's parliamentary affairs minister Shanti Dhariwal said, moving the resolution.

Leader of the opposition Gulab Chand Kataria of the BJP questioned the state's right to challenge the Act.

"Granting citizenship is a matter for the Centre. In such a situation do we have the right to challenge the CAA? The Congress should stop doing appeasement and vote bank politics," he said.

Salute to Rajasthan Govt for rejecting communal and black CAA bill.   This bill is agaisnt the teach of our Constitution and bjp has never done anything as per our constitutin.   Its trying its best to scrap the constitution and restore it with RSS agenda.    We should oppose any move by bjp against the value of constitution.   As bjp has no respect to our constitution, it has no right to be in power.    Many of bjp leaders are giving statemetns against the value of constitution and such leaders should be treated as anti indians and action be taken on them.
