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.

Bengaluru: In a fresh development in the alleged Hassan sex abuse case, JD(S) MLA H D Revanna, who was accused of sexually harassing his house help, has been booked for kidnapping a victim allegedly sexually assaulted by his son, Hassan MP Prajwal Revanna. The case was filed late Thursday evening at the KR Nagar police station in Mysuru.

The 20-year-old complainant from KR Nagara accused one Sathish Babanna of taking his mother away forcibly and keeping her in an unknown location at the behest of Revanna.

As per the FIR, Revanna has been named as accused 1 while Babanna was accused 2. The duo were booked under IPC Sections 364A (kidnapping for ransom), 365 (kidnapping or abducting with intent secretly and wrongfully to confine a person) and 34 (acts done by several persons in furtherance of common intention).

The complainant claimed that his mother, whose name and age were not revealed, had worked as a help in Revanna’s house and farm in Holenarasipura for six years, quit the job three years ago and returned to KR Nagara. She then worked for daily wages.

“Nearly three to four days before the Lok Sabha election, Sathish Babanna, who is known to us and hailed from our native place, took my mother to Holenarasipura after saying that Bhavani Revanna, the wife of MLA Revanna, had asked for her,” the complainant alleged, adding that Babanna dropped her back on the day of the polls.

Babanna allegedly told the victim’s mother and father to remain silent and evade the police if they came looking for them and to inform him of the developments.

On April 29, at around 9 pm, when the complainant was home, the suspect Babanna arrived, told the complainant’s mother that Revanna had asked for her and took her away on his motorcycle. The complainant claimed that he wasn’t aware of where Babanna took his mother and he had told him that if the police found her, a case would be registered and they would all go to jail.

On May 1, two of the complainant’s relatives called him on the phone and told him that there was a video of his mother being sexually assaulted by Prajwal and that it was a huge case, the FIR noted. He was also informed by his two friends of his "mother's videos being circulated".

When he asked Babanna later that night, he was allegedly told that there was a photo of his mother standing with a stick when Prajwal had quarrelled with someone earlier and an FIR had been registered. Babanna told the complainant that his mother would have to be released on bail, the FIR noted.

“Babanna told me not to speak on the matter on my phone and asked me to talk from a different phone,” he said, seeking action from the police.

The case has been transferred to the Special Investigation Team (SIT) set up to probe the Hassan sex scandal as per the government order.

Mysuru, Apr 29: Veteran politician and incumbent Chamarajanagar MP V Srinivas Prasad breathed his last at 76.The stalwart BJP leader, who had been battling health issues, succumbed to a severe heart attack, leaving behind a void in Karnataka's political arena.

A Dalit leader in the Old Mysuru region, Prasad was in Congress but joined the Bharatiya Janata Party before the 2018 Karnataka Assembly elections following a fallout with Chief Minister Siddaramaiah. The two had recently met in Mysuru and discussed the political scenario in the state.

Prasad extended support to the Congress in the Lok Sabha election 2024 and this is being seen as a crucial factor in the SC-reserved Chamarajanagar constituency, which Prasad represented in Parliament. On April 2, Prasad’s relatives and supporters joined Congress.

He served as a Union minister from 1999 to 2004 as the Loka Jana Shakthi MP. In the Karnataka Assembly elections, he was elected twice as an MLA and served as the state’s revenue minister.

Prasad, known for his distinguished political career spanning over five decades, was admitted to Manipal Hospital in Bengaluru due to urinary tract-related complications and age-related ailments.

However, his condition deteriorated rapidly, leading to his untimely demise in the wee hours of Monday.

Born on August 6, 1947, in Ashokapuram, Mysuru, Prasad's political journey was marked by significant milestones. He represented Chamarajanagar constituency as MP for an unprecedented seven terms and had derved as MLA from Nanjangud constituency twice.

He had held key ministerial portfolios including Minister for Food and Civil Supplies in the Atal Bihari Vajpayee government and Minister for Revenue and Muzrai in the Siddaramaiah-led Karnataka government.

He had joined the BJP officially in December 2016 and was elected as MP from Chamarajanagar again in 2019, showcasing his enduring popularity among constituents.

Prasad's demise has plunged the political fraternity and his supporters into mourning. His family members, political associates, and well-wishers are gathering to pay their final respects as his mortal remains are being transported from Manipal Hospital to his residence in Jayalakshmipuram, Mysuru.

The Exhibition Grounds in Mysuru will witness a stream of mourners as Prasad's mortal remains will be kept for public viewing, allowing people from all walks of life to bid farewell to their beloved leader.

Prasad's name had come up in the 'Tehelka tapes' controversy, after the sting operation by magazine Tehelka to expose defence deals under the Atal Bihari Vajpayee-led NDA government. The tapes showed Samata Party leader Jaya Jaitley allegedly telling an arms dealer to deposit money with Prasad, who was then in Bengaluru. However, Prasad denied these claims, saying he was in Mysuru at the time, and also sued Tehelka for defamation.

Canadian Police said they have arrested three Indians they suspect were part of the alleged hit squad that had killed Hardeep Singh Nijjar, a Sikh separatist leader involved with the Khalistan movement, which calls for an independent Sikh state.

Nijjar's killing had become the epicentre of a diplomatic row between India and Canada last year after Prime Minister Justin Trudeau alleged the role of "Indian agents" in the murder. India had rejected the charge as "absurd" and "motivated".

The three arrested Indians - Karan Brar, 22, Kamalpreet Singh, 22, Karanpreet Singh, 28 - were living as non-permanent residents in Alberta for three to five years, said Superintendent Mandeep Mooker, who leads the Integrated Homicide Investigation Team. The police have also released their photos.

They have been charged with first-degree murder and conspiracy to commit murder, showed court documents.

Police said that none of the suspects were known to them earlier and they were investigating their possible ties to the Indian government.

The murder remains "very much under active investigation," Royal Canadian Mounted Police (RCMP) Assistant Commissioner David Teboul told a press conference on Friday.

"There are separate and distinct investigations ongoing into these matters, certainly not limited to the involvement of the people arrested today, and these efforts include investigating connections to the government of India," CTV News quoted him as saying.

Nijjar, a Canadian citizen who was wanted in India on various terror charges, was shot dead outside a gurdwara in Surrey on June 18, 2023. Trudeau's charge against India sparked a massive row later that year with both countries expelling diplomats of the other country.

A fresh row erupted earlier this week after separatist slogans on 'Khalistan' were raised at an event addressed by Trudeau, prompting New Delhi to summon their Deputy High Commissioner and lodge a strong protest.

On the sidelines of the event, Trudeau told reporters that Nijjar's killing had created a "problem" that he could not have ignored.

India rejected his comment and said it once again showed Canada provides political space given to separatism, extremism, and violence. "This not only impacts India-Canada relations but also encourages a climate of violence and criminality in Canada to the detriment of its own citizens," foreign ministry spokesperson Randhir Jaiswal said.
