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, 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.

Jeddah, May 1: The government of India and its diplomatic missions in the Gulf Cooperation Council (GCC) States have begun elaborate preparations for the massive evacuation of their nationals stranded or needing to return once the lockdown travel restrictions are lifted.

The Indian missions in Saudi Arabia, the United Arab Emirates (UAE), Kuwait, Bahrain, Oman and Qatar have started registration for the return of their nationals. The move coincides with the directive of New Delhi to the Indian Air Force and Navy to get their big engines ready to bring back citizens stuck in the GCC states.

India’s External Affairs Minister S. Jaishankar has stated that the Indian missions in the GCC states have been liaising with local authorities for repatriation of Indians. More than eight millions Indians work and live in the Gulf countries.

The Indian Embassy in Saudi Arabia said that it has issued directives to their nationals who seek repatriation to India to fill an application form so as to facilitate their travel when the authorities lift the travel restrictions. Similar advisories have also been issued by the embassies in other Gulf States.

The Riyadh Embassy said in a press statement that the purpose is only to collect data and no decision has been taken yet regarding resumption of flights to India.

The Embassy will make an announcement with regard to repatriation of Indian nationals when the government of India takes a decision in this regard, the statement said, adding that separate forms have to be filled for each individual, including Indian worker or his or her family members.

The Embassy is in the process of working out the modalities of evacuation of stranded Indians in line with the directions of the government of India, the statement pointed out.

The Embassy and the Consulate General in Jeddah are closely monitoring the situation and are taking all the required measures to ensure the welfare of Indian citizens.

The missions have taken all the necessary measures for the supply of food, medicines and other emergency assistance to Indians in need and that is in coordination and cooperation with volunteers of major community organizations across the Kingdom.

These initiatives have been accelerated following the interactions of Ambassador Dr. Ausaf Sayeed with community volunteers and social workers from all parts of the Kingdom. The Embassy has also been in touch with all major companies in the Kingdom that employed Indian workers to carry out regular monitoring of the workers’ health, especially in labor camps, and take all other precautionary and preventive measures to ensure their health and safety.

According to the plan drawn up by the government of India, the first commercial flights from the Gulf could start after May 3, if the nationwide lockdown restrictions are not extended.

INS Jalashwa, an amphibious assault ship, and two Magar class tank-landing ships are being readied for the evacuation purposes, India’s IANS reported.

These ships, which have a total capacity of 2,000 people, have started making arrangements as per the standard protocols laid out to deal with suspected coronavirus cases like social distancing and sanitization.

The Indian Air Force has been evacuating citizens from coronavirus hit countries such as China, Japan, Iran, Italy and Kuwait since January. The force has stated that it has kept C-17 Globemaster and C-130s on standby which can be used whenever they are required.

Apart from them, Air India flights are also being kept on standby to pick up stranded Indians from the GCC countries.

15 Indian fatalities in western region

Speaking to Saudi Gazette, Indian Consul General Mohammed Noor Rahman Sheikh said that as of Thursday a total of 15 Indian coronavirus fatalities were reported in the western region.

These included seven cases in Makkah, six in Madinah and two in Jeddah. Around 140 Indians have tested positive in the region where most of the coronavirus cases in the Kingdom have been reported.

He said that permission was not accorded from the Ministry of Haj and Umrah to use the Indian Haj mission facility in Makkah as the center to assist the community members with regard to the coronavirus related cases.

“Our medical in charge is in Makkah and with the support of some other staffers, he has been actively involved in lending a helping hand to those Indian nationals who are in distress,” he said.

“We are in regular contact with the Ministry of Health officials in ensuring quick medical assistance to those who are tested positive.” He said preparations are under way for repatriation of Indians once permission is ready to take them home. “We are maintaining a database of all those who contacted the consulate with a request for their repatriation,” he added.

Meanwhile, the bodies of two Indians from the southern state of Kerala who succumbed to the pandemic were buried in Makkah. Naletil Muhammad from Ancharakkandi of Kannoor district, a restaurant worker in Makkah, gave samples at King Faisal Hospital a few days ago after developing symptoms of the disease.

When the hospital authorities advised him to remain in medical isolation, he reportedly preferred to remain in isolation at his residence where he succumbed to the pandemic after a few days.

Muhammad’s two sons, who are working in Riyadh, alerted his colleagues when they failed to contact him over phone. They found him dead at his residence on Monday. Eventually, Ministry of Health officials sent all his six colleagues to medical isolation.

Kottuwala Ippu Musliyar from Thennala, Vengara in Malappuram district, was a well-known social worker in Makkah. He died of coronavirus at Hira Hospital on Wednesday after undergoing treatment for a couple of days.

Mujeeb Pukkottoor, a prominent Indian social worker and general secretary of Makkah chapter of Kerala Muslim Cultural Center, was authorized by their spouses to carry out their burial procedures.

Accordingly Muhammad was buried on Wednesday and Ippu Musliyar on Thursday at the designated area for the coronavirus deceased persons at Sharaie Cemetery in Makkah.
