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.

Puttur: The long-cherished dream of a government medical college in Puttur has moved a decisive step closer to reality, with the Karnataka State Finance Department granting its official approval for the construction of a new 300-bed hospital.

Puttur MLA Ashok Kumar Rai announced the crucial development to reporters on Monday, confirming that the official communication from the finance department was issued on November 27. This 300-bed facility is intended to be the cornerstone for the establishment of the government medical college, a project announced in the state budget.

Fast-Track Implementation

The MLA outlined an aggressive timeline for the project:

•    A Detailed Project Report (DPR) for the hospital is expected to be ready within 45 days.

•    The tender process for the construction will be completed within two months.

Following the completion of the tender process, Chief Minister Siddaramaiah is scheduled to lay the foundation stone for the project.

"Setting up a medical college in Puttur is a historical decision by the Congress government in Karnataka," Rai stated. The project has an estimated budget allocation of Rs 1,000 crore for the medical college.

Focus on Medical Education Department

The MLA highlighted a key strategic move: requesting the government to implement the hospital construction through the Medical Education Department instead of the Health and Family Welfare Department. This is intended to streamline the entire process of establishing the full medical college, ensuring the facilities—including labs, operation theatres, and other necessary infrastructure—adhere to the strict guidelines set by the Medical Council of India (MCI). The proposed site for the project is in Bannur.

Rai also took the opportunity to address political criticism, stating that the government has fulfilled its promise despite "apprehensions" and "mocking and criticising" from opposition parties who had failed to take similar initiatives when they were in power. "Chief Minister Siddaramaiah has kept his word," he added.

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.

Domestic carrier IndiGo has cancelled over 180 flights from three major airports — Mumbai, Delhi and Bengaluru — on Thursday, December 4, as the airline struggles to secure the required crew to operate its flights in the wake of new flight-duty and rest-period norms for pilots.

While the number of cancellations at Mumbai airport stands at 86 (41 arrivals and 45 departures) for the day, at Bengaluru, 73 flights have been cancelled, including 41 arrivals, according to a PTI report that quoted sources.

"IndiGo cancelled over 180 flights on Thursday at three airports-Mumbai, Delhi and Bengaluru," the source told the news agency.

Besides, it had cancelled as many as 33 flights at Delhi airport for Thursday, the source said, adding, "The number of cancellations is expected to be higher by the end of the day."

The Gurugram-based airline's On-Time Performance (OTP) nosedived to 19.7 per cent at six key airports — Delhi, Mumbai, Chennai, Kolkata, Bengaluru and Hyderabad — on December 3, as it struggled to get the required crew to operate its services, down from almost half of December 2, when it was 35 per cent.

"IndiGo has been facing acute crew shortage since the implementation of the second phase of the FDTL (Flight Duty Time Limitations) norms, leading to cancellations and huge delays in its operations across the airports," a source had told PTI on Wednesday.

Chaos continued at several major airports for the third day on Thursday because of the cancellations.

A spokesperson for the Kempegowda International Airport (KIA) in Bengaluru said that 73 IndiGo flights had been cancelled on Thursday.

At least 150 flights were cancelled and dozens of others delayed on Wednesday, airport sources said, leaving thousands of travellers stranded, according to news agency Reuters.

The Directorate General of Civil Aviation (DGCA) has said it is investigating IndiGo flight disruptions and has asked the airline to submit the reasons for the current situation, as well as its plans to reduce flight cancellations and delays.

It may be mentioned here that the pilots' body, Federation of Indian Pilots (FIP), has alleged that IndiGo, despite getting a two-year preparatory window before the full implementation of new flight duty and rest period norms for cockpit crew, "inexplicably" adopted a "hiring freeze".

The FIP said it has urged the safety regulator, the DGCA, not to approve airlines' seasonal flight schedules unless they have adequate staff to operate their services "safely and reliably" in accordance with the New Flight Duty Time Limitations (FDTL) norms.

In a letter to the DGCA late on Wednesday, the FIP urged the DGCA to consider re-evaluating and reallocating slots to other airlines, which have the capacity to operate them without disruption during the peak holiday and fog season if IndiGo continues to "fail in delivering on its commitments to passengers due to its own avoidable staffing shortages."
