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.

Jammu, Jan 6: Union Minister Jitendra Singh on Sunday said India is the only shelter for religiously persecuted Hindus, Sikhs and other minorities who come from Pakistan, Bangladesh or Afghanistan, for the safety of their life and honour.

"India owes responsibility towards the minorities living in these countries which proclaim Islam as their state religion," Singh said here while launching the BJP's countrywide 10-day mass contact drive to spread awareness about the Citizenship Amendment Act (CAA).

Accompanied by senior party colleagues, including former deputy chief minister Kavinder Gupta and former minister Sat Sharma, he began by visiting the house of veteran columnist, writer and Padmashri awardee K L Pandita, where he spent time with them discussing the Act.

Later, he visited prominent social activist Amjad Mirza, eminent Sikh religious leader Baba Swaranjit Singh, retired High Court judge Justice G D Sharma, veteran journalist and former bureau head of Hind Samachar group Gopal Sachar, retired principal of Jammu government medical college Subhash Gupta, social activist and president of Peoples' Forum Ramesh Sabharwal, among others.

During his interaction with them, the Minister of State in the Prime Minister's Office claimed that Congress leaders and their allies protesting against the Act are doing so without "conviction".

He opined that if a "survey" was conducted among the family members of these Congress leaders, then, even they would not support their "anti-CAA stand".

"The tragedy of Congress party and contemporary leaders of Congress is that either they do not read their own history or are blissfully ignorant of the statements made by their own party patriarchs and former prime ministers," he said.

The minister recalled that the Nehru-Liaquat Pact of 1950 was inspired by the realisation on the part of the then Congress government headed by prime minister Jawaharlal Nehru that minorities, particularly Hindus, were not getting a fair deal in Pakistan.

"In 1949, Nehru had written a letter expressing concern about people coming in from then East Pakistan, which is now Bangladesh, and while doing so, he had referred to Hindus coming from there as 'refugees' and Muslims arriving here as 'immigrants'," Singh said.

Further, Nehru had stated that India owed a "responsibility" to these refugees, the minister said.

Referring to the opposition of senior Congress leaders Rahul Gandhi and Priyanka Gandhi to the amended legislation, the minister said someone should show them records of proceedings of the winter session of Parliament in 1950 when their great-grandfather (Nehru) had himself said that they deserved to be given citizenship and if the law was inadequate for it, then, the law should be changed.

"PM Modi should actually be given credit for showing courage and conviction to carry forward the task, which the Congress government lacked, to accomplish this," the minister opined.

Singh reiterated that a false fear psychosis against Muslims is being sought to be manufactured when there is no place as safe and comfortable to live for the community as India.

Turning the tables on the opposition to the National Population Register(NPR) and proposed National Register of Citizens (NRC), Singh pointed out that PM Modi and Union Home Minister Amit Shah have been stating that the exercise on NRC is yet to begin.

He also said that it was then Union home minister P Chidambaram, who had stated in Parliament in 2010 that NPR could be a basis for NRC.

Mumbai, Mar 8: A day after the Enforcement Directorate registered a money laundering case against Yes Bank founder Rana Kapoor and raided his premises, he was taken to the agency's office in Mumbai on Saturday for further questioning.

Kapoor, who was grilled by central agency's officials on Friday night at his Samudra Mahal residence in Mumbai, was shifted to the ED office in the metropolis around 12.30 pm.

ED officials said Kapoor was questioned throughout the night, with some rest time.

A senior ED official connected with the probe told IANS: "Kapoor will be questioned about Yes Bank loans to Dewan Housing Finance Limited (DHFL)."

The official said that during searches a lot of incriminating documents were found and the agency wanted to grill him on his links with DHFL promoters and other companies.

Kapoor's alleged role in the disbursal of loan to a corporate entity and kickbacks reportedly received in his wife's bank account are also under probe.

The ED had filed the money laundering case against Kapoor and raided his residence, apart from issuing a look-out circular so that he does not flee the country.

The ED registered a money laundering case against Kapoor as a continuation of its probe against the DHFL wherein it was allegedly found that Rs 12,500 crore was diverted to 80 shell companies using one lakh fake borrowers. The transactions with these shell companies date back to 2015.

An ED official in New Delhi told IANS that the DHFL probe revealed that funds diverted by the DHFL originated from Yes Bank.

He said that the searches at Kapoor's residence on Friday night were meant to find out any irregularity in grant of loans to the DHFL by the Yes Bank.

The ED has accused Kapil and Dheeraj Wadhawan of DHFL of purchasing shares in five firms -- Faith Realtors, Marvel Township, Abe Realty, Poseidon Realty, and Random Realtors -- after which they were amalgamated with Sunblink.

The outstanding loans of these five firms, totalling around Rs 2,186 crore till July 2019, were allegedly appropriated onto the books of Sunblink to cover up the diversion of loans acquired from DHFL.

The ED's action comes after the RBI superseded Yes Bank Board for 30 days and appointed an administrator, putting a cap of Rs 50,000 on withdrawals by account holders for a month.

The RBI said that the bank's board was superseded "owing to serious deterioration in the financial position of the bank".

Former SBI CFO Prashant Kumar was appointed as administrator of Yes Bank, which has over 1,000 branches and 1,800-plus ATMs across the country.

On Thursday, Union Finance Minister Nirmala Sitharaman said that the bank was on watch since 2017 and developments relating to it were monitored on a day-to-day basis.

Mar 19: Amidst spiralling cases of COVID-19 in the country, Union Minister of State for Health and Family Welfare Ashwini Kumar Choubey on Thursday advocated "absorbing sunlight" as a possible precaution against coronavirus that has claimed over 8,000 lives globally.

Speaking to reporters outside parliament, Choubey said 10-15 minutes in the sun would build immunity as sunlight provides Vitamin D.

"From 11 am to 2 pm the sun is shining brightly. We should spend at least 10-15 minutes to absorb sunlight so that we get vitamin D which improves the immunity of our body and also kills such viruses. All should be aware of (this fact)," he said when asked about the spread of coronavirus.

COVID-19 cases in India climbed to 169 on Thursday after 18 fresh cases were reported from various parts of the country, according to the Union health ministry.

The cases include 25 foreign nationals -- 17 from Italy, 3 from the Philippines, two from the UK, one each belonging to Canada, Indonesia and Singapore.

The figure also includes three deaths reported from Delhi, Karnataka and Maharashtra so far.

According to the World Health Organisation, the novel coronavirus has killed over 8,000 people globally and infected more than two lakh.
