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.

Dubai, Apr 26: Families were shattered as the three dead bodies of UAE-based Indian expats were returned to the country from New Delhi, India.

Family members waited outside the Indira Gandhi International Airport for hours, but they were later told to go back home as the remains of expats Jagsir Singh, Sanjeev Kumar and Kamlesh Bhatt were flown back to Abu Dhabi, following a new order implemented by India's Ministry of Home Affairs.

Inderjeet, brother-in-law of Sanjeev based in Al Ain, said their family in Punjab was devastated.

"This is a non-coronavirus death. We had a death certificate as proof and all necessary documents from Indian Embassy. But the body was returned while our family members waited outside the airport. This is very shocking," Inderjeet said.

"The body shouldn't have been returned. It's difficult to travel across states due to Covid-19 restrictions and also to arrange the ambulance," he added.

"Now the embassy has told me to come on Sunday. They said hopefully things will be sorted out in a day or two."

Meanwhile, the family of Kamlesh resides in the Indian state of Uttarakhand. This means, with existing travel restrictions, they had to secure permits from different states to reach New Delhi.

Dubai-based social worker Girish Pant, who is in touch with the family, said they are all depressed with the unfortunate turn of events.

"His brother Vimlesh had to return home without the remains. They are all clueless and in pain. With the new order from the Ministry of Home Affairs, I have informed the family that the body will reach them within 48 hours. I am also coordinating with the Indian Embassy," Pant said.

Washington, May 29: Reiterating his offer to mediate on the border dispute between India and China, US President Donald Trump has said that he spoke with Narendra Modi about the "big conflict" and asserted that the Indian Prime Minister is not in a "good mood" over the latest flare-ups between the two countries.

Speaking with the reporters in the Oval Office of the White House on Thursday, Trump said a "big conflict" was going on between India and China.

"I like your prime minister a lot. He is a great gentleman," the president said.

"Have a big conflict …India and China. Two countries with 1.4 billion people (each). Two countries with very powerful militaries. India is not happy and probably China is not happy," he said when asked if he was worried about the border situation between India and China.

"I can tell you; I did speak to Prime Minister Modi. He is not in a good mood about what is going on with China," Trump said.

A day earlier, the president offered to mediate between India and China.

Trump on Wednesday said in a tweet that he was "ready, willing and able to mediate" between the two countries.

Responding to a question on his tweet, Trump reiterated his offer, saying if called for help, "I would do that (mediate). If they thought it would help" about "mediate or arbitrate, I would do that," he said.

India on Wednesday said it was engaged with China to peacefully resolve the border row, in a carefully crafted reaction to Trump's offer to arbitrate between the two Asian giants to settle their decades-old dispute.

"We are engaged with the Chinese side to peacefully resolve it," External Affairs Ministry Spokesperson Anurag Srivastava said, replying to a volley of questions at an online media briefing.

While the Chinese Foreign Ministry is yet to react to Trump's tweet which appears to have caught Beijing by surprise, an op-ed in the state-run Global Times said both countries did not need such a help from the US President.

"The latest dispute can be solved bilaterally by China and India. The two countries should keep alert on the US, which exploits every chance to create waves that jeopardise regional peace and order," it said.

In Beijing, Chinese Foreign Ministry spokesman Zhao Lijian said on Wednesday that both China and India have proper mechanisms and communication channels to resolve the issues through dialogue and consultations.

Trump previously offered to mediate between India and Pakistan on the Kashmir issue, a proposal which was rejected by New Delhi.

The situation in eastern Ladakh deteriorated after around 250 Chinese and Indian soldiers were engaged in a violent face-off on the evening of May 5 which spilled over to the next day before the two sides agreed to "disengage" following a meeting at the level of local commanders.

Over 100 Indian and Chinese soldiers were injured in the violence.

The incident in Pangong Tso was followed by a similar incident in north Sikkim on May 9.
