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.

Jeddah, May 18: Saudi Arabia’s Grand Mufti and head of the Council of Senior Scholars and the Department of Scientific Research and Ifta Sheikh Abdul Aziz Al Asheikh ruled that it is permissible to perform Eid Al-Fitr prayer at home under exceptional circumstances similar to the current pandemic situation. The prayer consists of two rakats with reciting more numbers of takbeer and without a sermon.

Speaking to Okaz/Saudi Gazette, he said that Zakat Al-Fitr could be distributed through charitable societies if they are reliable ones, with the condition that it should be distributed before the day of Eid. The Grand Mufti urged parents to bring joy and happiness to their children and their families by spending more on them.

Meanwhile, Sheikh Abdul Salam Abdullah Al-Sulaiman, member of the Council of Senior Scholars and the Standing Committee of Fatwa, said that Eid prayer could be performed individually or in congregation.

Speaking to Okaz/Saudi Gazette, he said that the worshiper will recite takbeer to start salat and then follow it with six more takbeer in the first rakat before reciting Fatiha loudly and then it is ideal to recite Surah Al-Qaf.

In the second rakat, there will be five takbeer after the takbeer at the start of the rakat before starting to recite Surah Fatiha and then Surah Al-Qamar, following the example of the Prophet (peace be upon him). It is also ideal to recite Surah Al-A’la and Al-Ghashiya instead of Al-Qaf and Al-Qamar in each rakat respectively.

Sheikh Al-Sulaiman also cited the example of Anas Bin Malik, a prominent companion of the Prophet (pbuh). When Anas (May Allah be pleased with him), was at his home in Zawiya, a place near Basra, he did not find any Eid congregation prayer and therefore he performed prayer along with his family members and his aide Abdullah Bin Abi Otba.

The scholar said that the time for Eid prayer begins after sunrise and the best time is after the sun rises by the height of one or two spears as agreed by most scholars. This means 15 or 30 minutes after sunrise and its time continues until the end of the time of the Duha prayer; that is before the Zuhr prayer begins.

The prayer is forbidden at the moment when the sun rises, and the majority of jurists, including the schools of thought of Shafi, Maliki, and Hanbali opposed prayer at sunrise and favored to perform the prayer only after the sun rises by the height of one or two spears in the sky.

Regarding the recitation of takbeer on the occasion of Eid Al-Fitr, Sheikh Al-Suleiman said that it should begin during the night of the Eid and continue until the beginning of the Eid prayer.

Feb 22: Prime Minister Narendra Modi is unlikely to accompany US President Donald Trump and his family members during their visit to the Taj Mahal in Agra on Monday, official sources said.

The US President will arrive in Ahmedabad at around noon on February 24 for a less that 36-hour visit to India. He will be accompanied by a high-level delegation including First Lady Melania Trump, the President's daughter Ivanka Trump, son-in-law Jared Kushner and a galaxy of top US officials.

After attending an event at Ahmedabad, the Trumps will travel to Agra on Monday afternoon to visit the Taj Mahal before arriving at the national capital for the main leg of the visit.

When asked about reports that Modi may accompany Trump to Agra, official sources said there was no such plan.

They said the visit to the Taj Mahal in Agra by the US President and his family members will afford them the opportunity to view the historical monument suitably. Therefore, no official engagements or presence of senior dignitaries from the Indian side is envisaged there, the sources said.

Washington, Jul 7: The US military "will continue to stand strong” in relationship to a conflict between India and China or anywhere else, a top White House official said on Monday, after the navy deployed two aircraft carriers to the South China Sea to boost its presence in the region.

"The message is clear. We're not going to stand by and let China or anyone else take the reins in terms of being the most powerful, dominant force, whether it's in that region or over here,” White House Chief of Staff Mark Meadows told Fox News.

“And the message is clear. Our military might stands strong and will continue to stand strong, whether it's in relationship to a conflict between India and China or anywhere else,” Meadows said in response to a question.

He was told that India banned Chinese apps because Indian soldiers were killed by Chinese troops last month and asked what's mission of the two aircraft carriers - the Ronald Reagan and the Nimitz - and what's America's mission.

The troops of India and China are locked in an eight-week standoff in several areas in eastern Ladakh including Pangong Tso, Galwan Valley and Gogra Hot Spring. The situation deteriorated last month following the Galwan Valley clashes that left 20 Indian Army personnel dead as the two sides significantly bolstered their deployments in most areas along the LAC.

The Chinese military on Monday began withdrawing troops from the Galwan Valley and Gogra Hot Spring after National Security Advisor Ajit Doval and Chinese Foreign Minister Wang Yi held lengthy talks on Sunday. Doval and Wang are also the special representatives on the India-China boundary talks.

The United States has sent two of its aircraft carriers to the South China Sea. “Our mission is to make sure that the world knows that we still have the preeminent fighting force on the face of the globe,” Meadows said.

President Donald Trump has invested more in the US military, more in not only the hardware, but the men and women who serve so sacrificially each and every day, he said. “He (Trump) continues to do so,” he added.

China is engaged in hotly contested territorial disputes in both the South China Sea and the East China Sea. Beijing has built up and militarised many of the islands and reefs it controls in the region. Both areas are stated to be rich in minerals, oil and other natural resources and are vital to global trade.

China claims almost all of the South China Sea. Vietnam, the Philippines, Malaysia, Brunei and Taiwan have counter claims over the area.

Appearing on the same Fox News on Monday talk show with host Brian Kilmeade, influential Republican Senator Tom Cotton said that the US aircraft carriers are headed to the South China Sea to thwart off any Chinese misadventure against Taiwan or other countries in the region.

"That's one of the reasons why we have those aircraft carrier groups in the South China Sea. I mean, look what China did in the southwest. It's essentially invaded India over the last few weeks and killed Indian soldiers,” Cotton said.

"No country on China's periphery, right now, is safe from Chinese aggression. All those countries want a close relationship with the United States. We ought to have one,” Cotton said.
