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.

Newsroom, May 5: Following the union government's nod, preparations are afoot to bring back Indian nationals stranded abroad from May 7 onwards.

According to sources, in the first phase from May 7- 14, the government would allow more than 60 “non-scheduled, commercial” flights to operate from about 12 countries to India to bring back 15,000 citizens. At least half of those flights will be from the Gulf region, including UAE, Qatar, Saudi Arabia, Bahrain, Kuwait and Oman, while the rest would bring passengers from the U.S., the U.K., Singapore, Malaysia, Philippines and Bangladesh.

The flights would be spread over 10 States identified as having the largest numbers to return, with Kerala, Tamil Nadu and Delhi (NCR) receiving the maximum number of flights.

A meeting held at the Ministry of Civil Aviation looked specifically at flights, mainly operated by Air India, while it awaits a final plan from countries where Indians need to be airlifted from. The first flights planned at present are from Abu Dhabi, Dubai, Riyadh and Doha, flying directly to Kozhikode and Kochi.

While the full estimate of Indians needing to return home could cross ten lakhs (a million), with more than two lakhs having registered to return from the UAE alone, officials said their return would be “prioritised and staggered”.

Flight plan for return of Indian nationals stranded abroad:

New Delhi, Feb 10: A 44-year-old man allegedly killed his daughter and son before ending his life by jumping in front of a Delhi metro train at Haiderpur Badli Mor station on Sunday, police said.

No suicide note has been recovered, but police claimed that the man, Madhur Malani, was depressed since his sandpaper-manufacturing factory was closed some six months ago due to financial crunch leaving him jobless. Madhur's parents had been supporting his family financially since then.

He used to stay with his wife Rupali, daughter Samiksha (14) and six-year-old son Shraiyans at a rented house in northwest Delhi's Shalimar Bagh area, they said.

Rupali was not at home when Madhur strangled their children. He might have also smothered their daughter but the exact cause of death would be ascertained only after the post-mortem reports arrive, a police official said.

After killing his two children, he jumped in front of an approaching train at Haiderpur Badli Mor Metro station following which he was rushed to a hospital where doctors declared him 'brought dead', the official said.

Metro services on the Yellow Line were briefly delayed due to the incident.

"Delay in services from Samaypur Badli to GTB Nagar due to a passenger on track at Haiderpur Badli Mor," the Delhi Metro Rail Corporation (DMRC) tweeted.

After about 15 minutes, it again tweeted that normal services have been restored. The Delhi Metro's Yellow Line connects Samaypur Badli in Delhi to HUDA City Centre in Gurgaon.

The suicide was reported to the police around 5.40 pm while the Shalimar Bagh Police station received a call about the killings around 6.50 pm.

On reaching the house, police found bodies of the children lying in beds in two rooms. During enquiry, it was learnt that their father has left the house, a senior police officer said.

While police were trying to trace Madhur, they learnt about a suicide at the metro station. On verifying the details, it surfaced that Madhur committed suicide after killing his children, the officer said.

Rupali told police that she had gone to a nearby market around 3 pm and on returning home she found the bodies of her children while her husband was missing.

A case under relevant sections of the IPC has been registered and investigation was underway, Deputy Commissioner of Police (Northwest) Vijayanta Arya said.

Dirbrugarh, Feb 4: Three persons, including two BJP activists, have been arrested for allegedly attacking the residence of Union minister Rameswar Teli during anti-CAA protests in Assam, police said on Monday.

The house of Teli, Union Minister of State for Food Processing, in Upper Assam's Duliajan town was attacked on December 11 during the statewide stir against the contentious Citizenship (Amendment) Act, 2019.

"Based on CCTV footages, Debajit Hazarika, Vicky Sonar and Arup Kahar were arrested. We had picked them up on Sunday," Dibrugarh Superintendent of Police, Sreejith T told PTI.

A total of 18 persons have been arrested so far for allegedly attacking Teli's house, he said.

"These three persons were also involved in pelting stones on a police party during protests in Duliajan," Sreejith said.

A BJP source confirmed that Debajit Hazarika and Vicky Sonar are party activists.

Family members of the accused have given statements to the police on the arrested persons' alleged role in violence and attacking Teli's house, sources said.

When contacted, Teli said, "I do not know for what reasons they were apprehended. But if police arrested them after proper investigation, then there must be some truth. The trio stays near my house. They always attended my programmes with their families."

A total of 88 people have been arrested so far from Dibrugarh district for their alleged involvement in violence during protests against the Act.
