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.

Mangaluru, Nov 24: The original departure time of 11.10 pm was a distant memory for scores of Dammam-bound passengers at Mangaluru International Airport last Friday night, as their Air India Express flight was abruptly cancelled at the eleventh hour, sparking hours of frustration and chaos.

The flight, IX 885, initially scheduled to depart at 11.10 pm on November 22, was subject to two back-to-back reschedules—first pushed to 11.45 pm and then significantly postponed to 1.40 am—before the final, crushing announcement of cancellation was made. For the travellers, many of whom are likely expatriate workers with tight schedules, the last-minute change marked the beginning of a distressing ordeal.

"There was no drinking water, no food, and absolutely no proper guidance. We were left stranded like refugees," complained a stranded passenger.

According to multiple passenger accounts, the airline's ground staff failed to provide adequate support or essential amenities following the cancellation. Complaints poured in about the total absence of drinking water, food provisions, and any reliable guidance from the carrier's representatives. Travellers alleged they were left stranded for a considerable period, with no immediate arrangements or clear communication offered regarding accommodation or alternative travel to send them back home.

The incident has highlighted serious concerns over the carrier's contingency planning and customer service protocols during flight disruptions at one of India's key international gateways. The airline is yet to issue a comprehensive statement addressing the alleged lapse in passenger care.

Udupi, Dec 1: A horrific case of alleged rape has unfolded in Udupi, where a worker from a Hindutva organisation, previously arrested and released on bail for harassing a young woman, is now accused of waylaying and sexually assaulting her.

The arrested individual has been identified as Pradeep Poojary (26), a member of the Hindu Jagarana Vedike's Nairkode unit in Perdur.

Poojary had allegedly been relentlessly harassing the young woman, pressuring her to marry him. When she bravely stood up to him and refused his demands, she filed a formal complaint at the Hiriyadka police station. He was subsequently arrested in that initial harassment case but was later granted bail.

According to police reports, driven by the same malicious grudge, Poojary allegedly intercepted the woman again on November 29. While she was walking through a deserted area, the accused is claimed to have threatened her by grabbing her neck. When she again refused to marry him, he allegedly proceeded to rape her.

The survivor immediately informed her family about the traumatic assault. Following this, her parents lodged a complaint at the Udupi women’s police station.

Police arrested Poojary again and produced him before the court. He has since been remanded to judicial custody.

Bengaluru: The Vokkaligara Sangha on Thursday issued a stern warning to the Congress, saying the party could face serious electoral repercussions if Deputy Chief Minister D.K. Shivakumar is not appointed as Chief Minister.

The warning follows the public backing of Shivakumar’s chief ministerial ambition by top Vokkaliga pontiff Nirmalanandanatha Swami, who urged the Congress high command to honor his claim.

“The community supported Congress in the 2023 Assembly elections only because Shivakumar had a real chance to become CM. If he is cheated, we’ll teach the party a big lesson,” said newly elected Sangha president L. Srinivas. He added that Vokkaligas would organize protests under the guidance of community leaders.

General Secretary C.G. Gangadhar pointed out that Congress won more seats in the Vokkaliga-dominated Old Mysuru region due to Shivakumar’s influence, adding, “If Congress wants to retain power, Shivakumar should be made the CM.”

Outgoing president Kenchappa Gowda emphasized Shivakumar’s contribution to Congress’ victory. “Our community voted for Congress thinking he would become CM. Siddaramaiah has also served the party well, but Shivakumar should now be given a chance,” he said.

Former general-secretary Konappa Reddy appealed to Sonia and Rahul Gandhi to recognize Shivakumar’s loyalty and service, saying, “Congress is known to keep its promises. We hope it won’t break the promise made to him.”
