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, Nov 26: Karnataka is taking its first concrete steps towards lifting a three-decade-old ban on student elections in colleges and universities. Deputy Chief Minister D.K. Shivakumar announced Wednesday that the state government will form a small committee to study the reintroduction of campus polls, a practice halted in 1989 following incidents of violence.

Speaking at a 'Constitution Day' event organised by the Karnataka Congress, Mr. Shivakumar underscored the move's aim: nurturing new political leadership from the grassroots.

"Recently, (Leader of the Opposition in Lok Sabha) Rahul Gandhi wrote a letter to me and Chief Minister (Siddaramaiah) asking us to think about restarting student elections," Shivakumar stated. "I'm announcing today that we'll form a small committee and seek a report on this."

Student elections were banned in Karnataka in 1989, largely due to concerns over violence and the infiltration of political party affiliates into campus life. The ban effectively extinguished vibrant student bodies and the pipeline of young leaders they often produced.

Mr. Shivakumar, who also serves as the Karnataka Congress president, said that former student leaders will be consulted to "study the pros and cons" of the re-introduction.

Acknowledging the history of the ban, he added, "There were many criminal activities taking place back then. We’ll see how we can conduct (student) elections by regulating such criminal activities."

The Deputy CM reminisced about his own journey, which began on campus. He recalled his political activism at Sri Jagadguru Renukacharya College leading to his first Assembly ticket in 1985 at the age of 23. "That's how student leadership was at the time. Such leadership has gone today. College elections have stopped," he lamented, adding that for many, college elections were "like a big movement" where leaders were forged.

The move, driven by the Congress high command's push to cultivate young talent, will face scrutiny from academics and university authorities who have, in the past, expressed concern that the return of polls could disrupt the peaceful academic environment and turn campuses into political battlegrounds.

Mangaluru, Dec 3: A group of Congress workers gathered at the Mangaluru International Airport on Wednesday to welcome AICC general secretary K C Venugopal, but the reception quickly turned into a display of support for Deputy Chief Minister D K Shivakumar.

Venugopal arrived in the city to participate in the centenary commemoration of the historic dialogue between Mahatma Gandhi and Narayana Guru. The event, organised by the Sivagiri Mutt, Varkala, in association with the Mangalore University Sri Narayana Guru Study Chair, is being held on the university’s Konaje campus.

KPCC general secretary Mithun Rai and several party workers had assembled at the airport to receive Venugopal. However, the moment he stepped out, workers began raising slogans backing Shivakumar.

The university programme will be inaugurated by Chief Minister Siddaramaiah.

This show of support comes just a day after Siddaramaiah remarked that Shivakumar would lead the government “when the high command decides.” The chief minister made the comment after a breakfast meeting at Shivakumar’s residence—another public display of camaraderie between the two leaders amid ongoing attempts by the party high command to downplay their leadership rivalry.

Bengaluru: 'Nati koli saaru' (country chicken curry) considered one of Chief Minister Siddaramaiah’s favourites along with steaming hot idlis was on the breakfast menu at Deputy CM D K Shivakumar’s residence on Tuesday, according to official sources.

The spread also included 'nati koli' fry, vada and pongal, among other items, they said.

In an apparent show of unity, Siddaramaiah visited Shivakumar’s residence for breakfast, just days after the two leaders shared a meal amid a simmering power tussle in the state Congress.

Siddaramaiah drove to the Deputy CM’s residence in Sadashivanagar, where he was received by Shivakumar and his brother D K Suresh, who is a former Congress MP.

Suresh and Kunigal MLA H D Ranganath, a relative of Shivakumar, joined them for breakfast, which featured a mix of vegetarian and non-vegetarian dishes.

Speaking to reporters later, Siddaramaiah said Shivakumar had invited him during his visit to the CM’s residence for breakfast on Saturday.

Asked about the difference between the two meals, the chief minister said, "At his (Shivakumar’s) house it was non-veg, while at my house it was veg. He is a vegetarian, I am a non-vegetarian. I had not prepared non-veg. I told DK to get chicken from the village as you won’t get the original in Bengaluru."

Shivakumar said he had initially invited Siddaramaiah to his residence, but the CM had suggested visiting his place first and reciprocating later. "It was a vegetarian breakfast at the CM’s house on Saturday," he noted.

"Today, I invited him (the CM) to my house. He enjoyed the breakfast, which had his Mysuru taste," Shivakumar added. At this point, Siddaramaiah remarked that Shivakumar’s wife is also from Mysuru.

Saturday’s breakfast at Siddaramaiah’s official residence, held as part of efforts by the Congress high command to ease tensions in the leadership dispute between the two, reportedly included idlis and sambar, according to official sources.
