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.

Washington, Feb 19: Sri Srinivasan, a prominent Indian-American judge, has created history by becoming the first person of South Asian descent to lead a powerful federal circuit court considered next only to the US Supreme Court.

Srinivasan, 52, became the Chief Judge of the United States Court of Appeals for the DC Circuit.

An Obama appointee who has already been considered for a Supreme Court seat twice, donned the mantle of the chief judge of the DC federal court circuit on February 12.

Srinivasan succeeded Judge Merrick Garland, who has been a member of the DC Circuit since 1997 and Chief Judge since 2013. He will remain on the bench, a press release said.

Notably, Garland's nomination to the Supreme Court by the then president Barack Obama was blocked by Senate Republicans in 2016.

Srinivasan, was appointed to the US Court of Appeals for the District of Columbia Circuit in May 2013.

He was the first ever Indian-American to be appointed to the second most powerful court of the US.

Neomi Rao, nominated by President Donald Trump, is the second Indian American on this powerful judiciary bench.

History being made on the DC Court of Appeals. Congratulations, Judge Srinivasan! Senator Mark Warner said.

Congratulations to Judge Sri Srinivasan on becoming the Chief Judge of the U.S. Court of Appeals for the D.C. Circuit! A milestone for the Indian-American/Kansan community (and yet another piece of evidence my family can use that I'm underachieving), US Federal Communications Commission Chair Ajit Pai said.

According to The Washington Post, Srinivasan spoke recently about his path to the bench at an event celebrating women in the law, a field where men still dominate leadership positions.

"Everybody doubts their belonging and worthiness in some measure. I definitely did and still do. This is just going to be a part of the thing when you're looking out in the world in which everyone isn't like you. It's natural to doubt whether you belong and whether you're worthy, he said, "but you do belong and you are worthy.

Born in Chandigarh, and raised in Lawrence, Kansas, he received a B.A. from Stanford University, a J.D. from Stanford Law School, and an M.B.A. from the Stanford Graduate School of Business.

Following graduation, he served as a law clerk to Judge J. Harvie Wilkinson III of the US Court of Appeals for the Fourth Circuit, as a Bristow Fellow in the Office of the US Solicitor General, and as a law clerk to US Supreme Court Justice Sandra Day O'Connor.

From 2011 until his appointment to the US Court of Appeals, Judge Srinivasan served as the Principal Deputy Solicitor General of the United States.

He has argued 25 cases before the US Supreme Court. He has also taught appellate advocacy at Harvard Law School as well as a seminar on civil rights statutes and the Supreme Court at Georgetown University Law Center.

The unexpected lockdown to prevent spread of covid–19 has caused a serious damage to the lives of Indian expatriates irrespective of laborers and entrepreneurs in Kingdom of Saudi Arabia. Different stories of expatriates' ordeals are emerging from the region. 

Abdul Razaq, hailing from Udupi in Karnataka has been running small scale business at Jeddah, Saudi Arabia, based on oil refinery projects of the government. He was undergoing medical treatment for his cancer which is in fist stage. He explaines his ordeals caused by lockdown and stopping the flight facility. 

“I was regularly visiting home country for the treatment of cancer. Now I cannot go as international flight service has been stopped. I expect that government will hear problems of expatriates and will arrange facilities to take us back to home”, he said.

Mubeen from Bengaluru was working on temporary basis  for a company in Jubail. He had lost his jobs like some of his colleagues due to the lockdown.

“As everything was alright, I had brought my parents recently to Saudi Arabia on a visit visa. Things changed drastically with covid-19 attack. Continuous lockdown caused burden over the company and they removed temporary employees like me to control possible losses” he said.

“Now owner of the flat has been harassing me for the rent. I do not have money either to pay rent or to cover daily family expenses. I do not know what to do further”, he added. 

Iqbal from Mangaluru left for Saudi Arabia to help his family. He got a job in a juce centre in Dammam recently. Corona lockdown made his life difficult. He is eager to return his home country. 

“I came to Saudi Arbia because of financial difficulties as I had not found any job with good salary there. I thought I can earn well by going to Saudi Arabia. However, here too the salary was not so good. Now juice center is closed due to lockdown and sponsor is giving very small amount of money as salary through which we cannot afford our expenses and our families back in home,” he said.

“Here It is not easy get help of fellow Indians since most of them have their own ordeals. I would like to return home country; there however we can manage to get help of friends and relatives. I am looking forward the help of Indian government to start air facility for stranded NRIs,” he said. 

Mohsin from Mysuru is a taxi driver in Dammam, Saudi Arabia. He was earning on commission basis. Now Saudi government banned movement of taxis in the region, which pushed him and his fellow taxi drivers into trouble.

“We were earning commissions daily on the basis of trips. Now we cannot move outside with taxi since it may cause us to pay the fine of SR.10000. How can I manage my expenses and family members in home?”, he asked.

There are cases of pregnant women who have to return India for delivery. Those who brought family here on visit visa will not have insurance. Delivery charges and any kind of medical facilities without insurance in Saudi Arabia is very expensive. Expatriate Indians with such problems are awaiting government's help.

“I had brought my wife on one year visit visa. Now she is pregnant and I have to send her back to home for delivery. If lockdown continues, it is difficult to send back and we have to spend big amounts for delivery without insurance. It is a big burden to me as I work for small salary in a company”, said Yunus from Hyderabad, who is living in Jeddah, Saudi Arabia.

Lockdown is haunting even entrepreneurs in Saudi Arabia. Most of expatriates in the industrial hub of Jubail are doing business based on Saudi Government’s oil refinery projects. Saudi Arabia temporarily stopped most of the projects as part of public health safety measures to maintain social distance. 

“We are doing business based on oil refinery projects. Now projects are stopped. We brought around 1100 people on work permit visa on temporary basis. And also, we have around 1200 permanent workers. It is a big burden to provide them with food, accommodation and salary. It may cause a big loss for our company”, said owner of expatriates company, Sheikh Mohammed.

Saudi Arabia had reported first corona virus affected case in March 2, 2020. At the end of March, it was 1600 and now it already corssed 6000. Saudi Health ministry has cautioned the number of affected people may rise 10000 to 200,000 and directed for more precautionary measures. In such case, the Indian expatriates may have to face crisis in the region. 

Indian expatriate organizations are demanding for immediate intervention of Indian government to ensure better quarantine facility and treatment of NRIs in Saudi Arabia as the cases are increasing rapidly. The condition of laborers in some of the camps are such that seven to eight people should share a single bed room. 

“Normally if there is a flat, it will consist three to four bed rooms. In single bedroom companies will provide three four bunk beds and six to eight people should share the room. In such cases, if a person affected with virus it will spread quickly to others. Thus, Indian government should ensure quarantine facility for NRIs”, says Wasim Rabbani, president of Indian Social Forum, Eastern Region, Saudi Arabia. 

President of Karnataka Non Residential Indians, A forum for the NRI organizations of Karnataka, Zakaria Muzain says Indian Government should immediately interfere to bring back those stranded NRIs who wish to return home. Government should intervene to pressure Indian embassy to take the issues of troubled expatriates. 

“Government should make special flight arrangement for such NRIs in trouble. It should also arrange quarantine facility for those who return to India. Already there are many Non-Governmental charity organization which have come forward to give their facilities for NRIs”, he said. 

NRIs from all categories are looking forward for the help of Indian government. It is important to Indian government to take quick action as the problem is increasing in Saudi Arabia.
