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.

Riyadh, Feb 28: Saudi Arabia on Thursday (Feb 27) suspended visas for visits to Islam's holiest sites for the "umrah" pilgrimage, an unprecedented move triggered by coronavirus fears that raises questions over the annual hajj.

The kingdom, which hosts millions of pilgrims every year in the cities of Mecca and Medina, also suspended visas for tourists from countries with reported infections as fears of a pandemic deepen.

Saudi Arabia, which so far has reported no cases of the virus but has expressed alarm over its spread in neighbouring countries, said the suspensions were temporary. It provided no timeframe for when they will be lifted.

"The kingdom's government has decided to take the following precautions: suspending entry to the kingdom for the purpose of umrah and visit to the Prophet's mosque temporarily," the foreign ministry said in a statement.

"Suspending entry into the kingdom with tourist visas for those coming from countries, in which the spread of the new coronavirus (COVID-19) is a danger."

The move comes as Gulf countries implement a raft of measures, including flight suspensions and school closures, to curb the spread of the disease from people returning from pilgrimages to Iran.

Even as the number of fresh coronavirus cases declines at the epicentre of the disease in China, there has been a sudden increase across the Middle East.

Since its outbreak, the United Arab Emirates has reported 13 coronavirus cases, Kuwait has recorded 43, Bahrain has 33 and Oman is at four cases.

Iran has emerged as a major hotspot in the region, with 19 fatalities from 139 infections - the highest death toll outside China, where COVID-19 originated.

While no cases have been reported in Saudi Arabia, one citizen is reported to be infected in Kuwait along with four Saudi women in Bahrain - all of whom had returned from Iran.

'UNPRECEDENTED' MOVE

The umrah, which refers to the Islamic pilgrimage to Mecca that can be undertaken at any time of year, attracts millions of devout Muslims from all over the globe each year.

There was no clarity over how the move would affect the annual hajj pilgrimage due to start in late July.

Some 2.5 million faithful travelled to Saudi Arabia from across the world to take part in last year's hajj - one of the five pillars of Islam.

The event is a key rite of passage for Muslims and a massive logistical challenge for Saudi authorities, with colossal crowds cramming into relatively small holy sites.

"This move by Saudi Arabia is unprecedented," Ghanem Nuseibeh, founder of London-based risk consultancy Cornerstone Global Associates, told news agency.

"The concern for Saudi authorities would be Ramadan, which starts at the end of April, and hajj afterwards, should the coronavirus become a pandemic."

The holy fasting month of Ramadan is considered a favourable period by Muslim pilgrims to perform the umrah.

Saudi Arabia's custodianship of Mecca and Medina - Islam's two holiest sites - is seen as the kingdom's most powerful source of political legitimacy.

But a series of deadly disasters over the years has prompted criticism of the Sunni kingdom's management of the pilgrimage.

In September 2015, a stampede killed up to 2,300 worshippers - including hundreds of Iranians - in the worst disaster ever to strike the pilgrimage.

The pilgrimage forms a crucial source of revenue for the government, which hopes to welcome 30 million pilgrims annually to the kingdom by 2030.

De facto ruler Crown Prince Mohammed bin Salman's Vision 2030 reform plan seeks to shift the economy of Saudi Arabia - the world's top crude exporter - away from oil dependency towards other sources of revenue, including religious tourism.

Amid the rapid spread of the novel coronavirus (COVID-19), which has infected 73 people in India and killed more than 4,500 individuals globally, doctors have advised that in addition to regularly washing hands, one should also disinfect their smartphone every 90 minutes with alcohol-based hand sanitizer.

Ravi Shekhar Jha, Head of Department at Fortis Escorts Hospital in Faridabad said the best method to disinfect your smartphone is to use regular doctor spirit or the alcohol-based hand sanitizer at least every 90 minutes.

"Avoid touching your eyes, mouth, or nose. The best option is to use a phone cover or a Bluetooth device and try to touch your phone as less as possible. We would also recommend cleaning your phone at least twice a day," Jha told IANS.

According to research, published in 2018 by Insurance2Go, a gadget insurance provider, revealed that smartphone screens have three times more germs than a toilet seat.

One in 20 smartphone users was found to clean their phones less than every six months, said the study.

"In the time of fear of coronavirus, smartphones should also be disinfected with alcohol-based sanitizer rub. Pour few drops of sanitizer on a tiny clean cotton pad and rub it safely on your entire phone," said Jyoti Mutta, Senior Consultant, Microbiology, Sri Balaji Action Medical Institute in New Delhi.

"You can repeat this process every evening coming back home after an entire day out at work and once in the morning before going out," Mutta added.

"Maintain basic cleanliness, and try to avoid using other's phones especially if suffering from respiratory illness or flu-like symptoms as there is no other way to disinfect these regular gadgets," she stressed.

Another study from the University of Surrey in the UK, also found that the home button on your smartphone may be harbouring millions of bacteria - some even harmful.

The World Health Organisation (WHO) declared the novel coronavirus as a global pandemic on Wednesday. The death toll of COVID-19 has crossed the 4,500 marks and confirmed cases globally have touched one lakh as per the reports.

According to Suranjeet Chatterjee, Senior Consultant in Internal Medicine Department of Indraprastha Apollo Hospitals in New Delhi, "We should frequently wash our hands, cover our coughs and it is important to adapt to other good hygiene habits that are most important in such a situation."

"Coronavirus and other germs can live on surfaces like glass, metal or plastics and phones are bacteria-ridden. It is necessary that we sanitize our hands frequently and make sure that our hands are clean all the time," Chatterjee told IANS.

"The emphasis should be laid on sanitising our hands rather than sanitizing the phone - once in a while the phone can be sanitized under the guidance of the makers of the phone," Chatterjee stressed.

According to the global health agency, the most effective way to protect yourself against coronavirus is by frequently cleaning of your hands with alcohol-based hand rub or washing them with soap and water.

The WHO's report showed the virus infects people of all ages, among which older people and those with underlying medical conditions are at a higher risk of getting infected.

People should eat only well-cooked food, avoid spitting in public, and avoid close contact, the WHO said, adding that it is important for people to seek medical care at the earliest if they become sick.

Lukung, Jul 17: Union Defence Minister Rajnath Singh on Friday assured that not an inch of our land can be taken by any power in the world while he interacted with the Indian Army and ITBP personnel at Lukung.

Referring to the India-China border standoff, he said, "Talks are underway to resolve the border dispute but to what extent it can be resolved I cannot guarantee. I can assure you, not one inch of our land can be taken by any power in the world."

Emphasising on finding a diplomatic solution to the standoff, he further said, "If a solution can be found by talks, there is nothing better."
"Recently what happened between troops of India and China at PP14, how some of our personnel sacrificed their lives protecting our border. I am happy to meet you all but also saddened because of their loss. I pay my tributes to them," he added.

Singh interacted with the Army and Paramilitary troops here along with Chief of Defence Staff General Bipin Rawat and Army Chief General MM Naravane.

Earlier today, the Defence Minister witnessed para dropping and scoping weapons here. He also inspected a Pika machine gun.

Indian Army T-90 tanks and BMP infantry combat vehicles carried out the exercise at Stakna, Leh in presence of Singh, Chief of Defence Staff and Army Chief.

Defence Minister is on a two-day visit to Ladakh and Jammu and Kashmir. He will take stock of the situation at both the Line of Actual Control (LAC) and the Line of Control (LOC).

While Pakistan constantly violates ceasefire from across the LoC, China has continued to intrude into Indian territory in Ladakh region in recent past, escalating tensions between India and its eastern neighbour.

On June 15, twenty Indian soldiers laid out their lives during combat with Chinese forces in Galwan valley, leading to tensions between both nations. Chinese soldiers subsequently started moving back following dialogues between two countries through the military level and diplomatic level.

Singh was accompanied by the Chief of Defence Staff General Bipin Rawat and Army Chief General MM Naravane.
