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.

Congress president Mallikarjun Kharge on Thursday announced that he will convene a high-level meeting in New Delhi with senior leaders — including Rahul Gandhi, Karnataka Chief Minister Siddaramaiah and Deputy Chief Minister D.K. Shivakumar — to resolve the escalating leadership turmoil in Karnataka and “put an end to the confusion.”

Kharge said the discussions would focus on the way forward for the ruling party, as rumours of a possible leadership change continue to swirl. The speculation has intensified after the Congress government crossed the halfway mark of its five-year term on November 20, reviving talk of an alleged 2023 “power-sharing agreement” between Siddaramaiah and Shivakumar.

“After reaching Delhi, I will call three or four important leaders and hold discussions. Once we talk, we will decide how to move ahead and end this confusion,” Kharge told reporters in Bengaluru, according to PTI.

When asked specifically about calling Siddaramaiah and Shivakumar to Delhi, he responded: “Certainly, we should call them. We will discuss with them and settle the issue.”

He confirmed that Rahul Gandhi, the Chief Minister, the Deputy Chief Minister and other senior members would be part of the deliberations. “After discussing with everyone, a decision will be made,” he said.

Meanwhile, Siddaramaiah held a separate strategy meeting at his Bengaluru residence with ministers and leaders seen as his close confidants, including G. Parameshwara, Satish Jarkiholi, H.C. Mahadevappa, K. Venkatesh and K.N. Rajanna.
Signalling calm, the Chief Minister told reporters, “Will go to Delhi if the high command calls.”

Shivakumar echoed a similar stance, saying he too would head to the national capital if summoned by the party leadership.

Mangaluru: Police Commissioner Sudheer Kumar Reddy C H has warned of strict action against individuals spreading rumours and attempting to create insecurity within the Muslim community and fuel hatred between Hindus and Muslims through social media.

Referring to a recent social media post alleging that police personnel had entered a masjid premises to check whether beef was being cooked, the commissioner said miscreants were attempting to push their communal agenda. 

“A group of people, both from Mangaluru and abroad, are trying hard to spread rumours. For the past 10 days, they have been attempting to rake up old issues, highlight routine matters as controversies, or fabricate news altogether,” he said.

He reiterated that any such attempts to disturb communal harmony would invite legal action. “Cases will be registered and the accused will be brought to book,” he stated.

Tejas.jpg

An Indian Air Force (IAF) Tejas fighter jet crashed on Friday, November 21, afternoon during its aerial demonstration at the Dubai Air Show, plunging to the ground at around 2:10 pm local time while performing a manoeuvre before thousands of spectators.

The IAF confirmed the incident, stating that a Tejas aircraft participating in the show had crashed and that further details were being gathered. An Air Force spokesperson said more information would be shared after initial assessments.

The crash sent thick black smoke billowing into the sky near the airport, causing panic among visitors, including families and children who had gathered to watch the display. Authorities have not yet confirmed whether the pilot managed to eject before the aircraft went down. Emergency response teams rushed to the scene, and officials have not released information on casualties or damage so far.

The Tejas is a 4.5-generation, multi-role fighter aircraft developed indigenously by Hindustan Aeronautics Limited (HAL). Designed for versatility, it is capable of offensive air support, close combat, ground attack missions and maritime operations. The aircraft family includes single-seat fighters and twin-seat trainers for both the Air Force and Navy.

HAL describes the latest version, the LCA Mk1A, as the most advanced in the series, featuring an AESA radar, an upgraded electronic warfare suite with radar-warning and self-protection jamming, smart multifunction displays, a digital map generator, a combined interrogator–transponder system and a modern radio altimeter. These enhancements significantly improve the aircraft’s combat capability and survivability.

Further updates from IAF and UAE authorities are awaited.
