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 26: Assembly Speaker and local MLA U.T. Khader has initiated a high-level push to resolve one of Mangaluru’s longest-standing traffic headaches: the narrow, high-density stretch of National Highway-66 between Nanthoor and Talapady.

He announced on Tuesday that a formal proposal has been submitted to the Union Ministry of Road Transport and Highways (MoRTH) seeking approval to prepare a Detailed Project Report (DPR) for the widening of this crucial corridor.

The plan specifically aims to expand the existing 45-meter road width to a full 60 meters, coupled with the construction of dedicated service roads. Khader highlighted that land for a 60-meter highway was originally acquired during the initial four-laning project, but only 45 meters were developed, leading to a perpetual bottleneck.

"With vehicle density rising sharply, the expansion has become unavoidable," Khader stated, stressing that the upgrade is essential for ensuring smoother traffic flow and improving safety at the city's main entry and exit points.

The stretch between Nanthoor and Talapady is a vital link on the busy Kochi-Panvel coastal highway and connects to major city junctions. The move to utilize the previously acquired land for the full 60-meter width is seen as a necessary measure to catch up with the region's rapid vehicular growth and prevent further traffic gridlocks.

Mangaluru: In a significant step to curb online hate and intimidation, Mangaluru City Police have registered a suo motu case against multiple Instagram accounts accused of circulating alleged provocative and threatening content.

While monitoring social media activity on Tuesday, Kankanady Town PSI Anitha Nikkam identified the Instagram handle ‘team_targetttt_900’ for posting a hate message alongside images of lethal weapons. Another account, ‘team_nagara_900’, allegedly shared a threatening post targeting activist Bharath Kumdelu, tagging additional pages such as KARAVALI-OFFICIAL.

Several other accounts — including ‘immu_bhai.fan’, ‘target_boy_900’, ‘kings_of_manglore’, ‘team_target_boys.900’, ‘arshad_mangalore’, ‘target_ka19_ullal’, ‘team_target__’, ‘troll_tigersz_900’, ‘tr_group_900’, and ‘team_target_900’ — are also under scrutiny for spreading similar inflammatory material, police said.

Authorities have urged citizens, especially young social media users, to report suspicious pages and avoid engaging with groups that glorify violence or threaten individuals. Online hate can quickly escalate into real-world harm, and police stress that sharing or promoting such content can attract legal consequences.

Udupi, Dec 2: A wave of regional pride is sweeping through Udupi district as Shagun S Verma Hegde, a talented Class 9 student from Christ King English Medium High School, Karkala, has been named the captain of the Indian National Team for the Under-15 Girls’ Volleyball Championship.

Shagun holds the unique distinction of being the sole player from Karnataka selected to represent the country in the prestigious international tournament. The championship, organized by the School Games Federation, is scheduled to take place in Shangluo, China, from December 3 to 13, where Shagun will lead the national squad.

A Remarkable Journey to the Top

Shagun’s selection is a testament to her dedication and exceptional skill on the court. Her journey included several rigorous rounds of selection:

•    She was the only player from Udupi district to qualify for the state-level selection camp.

•    Out of eight players from Karnataka who advanced to the national selection camp in Pune, Maharashtra, Shagun was the only one to secure a place in the final national squad.

•    The national camp saw participation from approximately 200 players, which was shortlisted to 23. Shagun not only made the final cut but was also ranked as the second-best player overall, solidifying her leadership role.

Shagun, who is the daughter of Sandesh Verma and Shruthiraj of Kallotte, Karkala, has trained under experienced coaches Santosh D’Souza, Jeevan D’Silva, Jairaj Poojary, and Ramesh. Her selection as the team captain has brought profound honour to her family, school, the Udupi district, and the entire state of Karnataka.
