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.

New Delhi, Jan 30: In a major shift of strategy ahead of the Delhi assembly polls, the Bharatiya Janata Party (BJP) has decided to rope in its senior leaders for massive public rallies.

Its star campaigners like Prime Minister Narendra Modi, Union Home Minister Amit Shah, BJP chief JP Nadda, Uttar Pradesh Chief Minister Yogi Adityanath, and other union ministers would now be addressing massive public rallies in addition to ongoing neighbourhood meetings.

"The big rallies would begin from February 1. While 'Nukkad' meetings will take place till the last day of campaigning, there would be big rallies of the top leadership of the party, " informed a senior party leader.

Sources said the BJP has changed its strategy after the success of its grassroots contact programme as the party wants to consolidate its gains.

"As part of the reworked strategy the BJP has asked its various Mandals to organise public meetings of 10,000-15,000 people in each assembly segment to reach out to the masses," sources added.

While there are two planned for Prime Minister Modi, two have been planned for JDU chief and Bihar Chief Minister Nitish Kumar along with Nadda and Amit Shah. Yogi Aadityanath too would be addressing 12 rallies.

The party is leaving no stone unturned to secure massive gains, which it feels can be converted to victory in the forthcoming polls.

Party sources feel that the relentless campaigning under the guidance of Amit Shah and Nadda has ensured that the morale of party cadre is at an all-time high.

"The neighbourhood meetings have ensured that we have been able to make the people of Delhi aware of the lack of work under the Arvind Kejriwal led Aam Aadmi Party government. They have also been apprised about the anti-national views of the opponents and we think that this is expected to turn the polls into our favour," sources added.

Delhi is scheduled for assembly polls on February 8 and the results for the 70 constituencies will be declared on February 11.

As part of the new strategy, senior leaders like JP Nadda, Amit Shah, Uttar Pradesh chief minister Yogi Adityanath, ministers like Rajnath Singh and Smriti Irani would be holding public rallies in various parts of the city. Several other chief ministers from various BJP ruled states are also expected to be roped in for the campaign.

The strategy for reach out to the masses is an attempt at weakening the hold of AAP on Delhi. With positive feedback coming after the success of the neighbourhood meetings in the past week, the BJP is now looking to increase its potential reach with polls just days away.

Till now the party had deployed 70 union ministers to hold at least one public meeting and one 'padayatra' each as part of the campaign.

An Indian national was killed and four others injured in alleged firing by Nepal police personnel along the India-Nepal border in Bihar's Sitamarhi district today.

Sources said the firing took place after a clash between the Indians and personnel of Nepal police at the Lalbandi-Janki Nagar border in Pipra Parsain panchayat under Sonebarsha police station of the district.

Jitendra Kumar, the additional director general of police (headquarters), confirmed the death and injuries. The place of firing falls under Nepal jurisdiction.

Locals said Vikesh Kumar Rai, 25, died on the spot and Umesh Ram and Uday Thakur received bullet injuries when they were working in an agricultural field. Another person, Lagan Rai, is said to have been detained by the Nepali police.

Injured persons were rushed to Sitamarhi Sadar Hospital for better treatment.

Vikesh Kumar Rai’s father, Nageshwar Rai, said that his agriculture land falls under Narayanpur in Nepal where his son was working.

On May 17, Nepal police had fired blank rounds to disperse dozens of Indians trying to cross the border. It was not clear if they were also farmers.

The district magistrate and the superintendent of police of Sitamarhi have rushed to the spot.

Nepal shares a 1,850-kilometre (1,150-mile) open border with India and people travel across it for work and to visit family. It had closed its international borders on March 22 amid the coronavirus pandemic.

Washington, May 29: US President Donald Trump while speaking with reporters at the White House on Thursday said that he is more liked in India than the media in his own country --the United States.

"I know. And they like me in India. I think they like me in India certainly more than the media likes me in this country, " Trump told reporters at his Oval office.

"And I like Modi (Prime Minister Narendra Modi). I like your prime minister a lot. He's a great gentleman. A great gentleman," he added further while briefing the reporters.

But when asked over ties between India and China, the US President said, "They have a big conflict going with India and China. Two countries with 1.4 billion people. Two countries with very powerful militaries. And India is not happy, and probably China is not happy."

Reiterating his offer to mediate between India and China on the border issue, Trump said that he spoke to Prime Minister Narendra Modi, who is not in "good mood" about the ongoing situation with Beijing.

However, informed sources from the Ministry of External Affairs told ANI on Friday that there has been no recent contact between Prime Minister Modi and the US President. The last conversation between them took place on April 4, 2020, on the subject of hydroxychloroquine.

Asked about his Wednesday's tweet regarding his offer to mediate between India and China, Trump said, "I would do that. If they (China and India) thought it would help." However, Trump did not clarify when did he speak to Modi.

Trump on Wednesday tweeted that he is "ready, willing and able to mediate" between India and China."We have informed both India and China that the United States is ready, willing and able to mediate or arbitrate their now raging border dispute," the US President said.

In response to Trump's mediation offer, India said on Thursday that it is engaged with the Chinese side to resolve the border issue peacefully.

India's Ministry of External Affairs spokesperson Anurag Srivastava said that the two sides have established mechanisms both at military and diplomatic levels to resolve situations that may arise in border areas peacefully through dialogue and "continue to remain engaged through these channels."

Indian and Chinese field commanders have been holding talks on de-escalating the tensions.

China has also struck a conciliatory tone on the border issue with India, saying the two countries pose no threat to each other and should resolve their differences through communication, while not allowing them to overshadow bilateral relations.

"We should never let differences overshadow our relations. We should resolve differences through communication. China and India should be good neighbours of harmonious coexistence and good partners to move forward hand in hand," said Chinese Ambassador to India, Sun Weidong, on Wednesday.

The tensions escalated between India and China following a number of confrontations between soldiers of both armies.

Troops of India and China were engaged in two face-offs in Eastern Ladakh and North Sikkim along the disputed Line of Actual Control (LAC), where troops from both sides suffered injuries early this month.

Studies over the anti-malarial drug, which is believed to cure the highly contagious coronavirus, have shown side-effects, according to the Centers for Disease Control and Prevention and the World Health Organisation. But Trump continues to defend his decision to take hydroxychloroquine saying he believes that it gives an additional level of safety.
