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.

Dubai/Washington, Jan 7: Iran's Supreme Leader Ayatollah Ali Khamenei wept in grief with hundreds of thousands of mourners thronging Tehran's streets on Monday for the funeral of military commander Qassem Soleimani, killed by a U.S. drone on U.S. President Donald Trump's orders.

The coffins of General Qassem Soleimani and Iraqi militia leader Abu Mahdi al-Muhandis, who also died in Friday's attack in Baghdad, were draped in their national flags and passed from hand to hand over the heads of mourners in central Tehran.

Responding to Trump's threats to hit 52 Iranian sites if Tehran retaliates for the drone strike, Iran's President Hassan Rouhani pointedly wrote on Twitter: "Never threaten the Iranian nation." And Soleimani's successor vowed to expel U.S. forces from the Middle East in revenge.

Khamenei, 80, led prayers at the funeral, pausing as his voice cracked with emotion. Soleimani, 62, was a national hero in Iran, even to many who do not consider themselves supporters of Iran's clerical rulers.

Aerial footage showed people, many clad in black, packing thoroughfares and side streets in the Iranian capital, chanting "Death to America!" - a show of national unity after anti-government protests in November in which many demonstrators were killed.

The crowd, which state media said numbered in the millions, recalled the masses of people that gathered in 1989 for the funeral of the Islamic Republic's founder, Ayatollah Ruhollah Khomeini. Soleimani, architect of Iran's drive to extend its influence across the Middle East, was widely seen as Iran's second most powerful figure behind Khamenei.

His killing of Soleimani has prompted concern around the world that a broader regional conflict could flare.

Trump on Saturday vowed to strike 52 Iranian targets, including cultural sites, if Iran retaliates with attacks on Americans or U.S. assets, and stood by his threat on Sunday, though American officials sought to downplay his reference to cultural targets. The 52 figure, Trump noted, matched the number of U.S. Embassy hostages held for 444 days after the 1979 Iranian Revolution.

Rouhani, regarded as a moderate, responded to Trump on Twitter.

"Those who refer to the number 52 should also remember the number 290. #IR655," Rouhani wrote, referring to the 1988 shooting down of an Iranian airline by a U.S. warship in which 290 were killed.

Trump also took to Twitter to reiterate the White House stance that "Iran will never have a nuclear weapon" but gave no other details.

'ACTIONS WILL BE TAKEN'

General Esmail Ghaani, Soleimani's successor as commander of the Quds Force, the elite unit of Iran's Revolutionary Guards charged with overseas operations, promised to "continue martyr Soleimani's cause as firmly as before with the help of God, and in return for his martyrdom we aim to rid the region of America."

"God the Almighty has promised to take martyr Soleimani's revenge," he told state television. "Certainly, actions will be taken."

Other political and military leaders have made similar, unspecific threats. Iran, which lies at the mouth of the key Gulf oil shipping route, has a range of proxy forces in the region through which it could act.

Iran's demand for U.S. forces to withdraw from the region gained traction on Sunday when Iraq's parliament passed a resolution calling for all foreign troops to leave the country.

Iraqi caretaker Prime Minister Abdel Abdul Mahdi told the U.S. ambassador to Baghdad on Monday that both nations needed to implement the resolution, the premier's office said in a statement. It did not give a timeline.

The United States has about 5,000 troops in Iraq.

Soleimani built a network of proxy militia that formed a crescent of influence - and a direct challenge to the United States and its regional allies led by Saudi Arabia - stretching from Lebanon through Syria and Iraq to Iran. Outside the crescent, Iran nurtured allied Palestinian and Yemeni groups.

He notably mobilised Shi'ite Muslim militia forces in Iraq that helped to crush ISIS, the Sunni militant group that had seized control of swathes of Syria and Iraq in 2014.

Washington, however, blames Soleimani for attacks on U.S. forces and their allies.

The funeral moves to Soleimani's southern home city of Kerman on Tuesday. Zeinab Soleimani, his daughter, told mourners in Tehran that the United States would face a "dark day" for her father's death, adding, "Crazy Trump, don't think that everything is over with my father's martyrdom."

NUCLEAR DEAL

Iran stoked tensions on Sunday by dropping all limitations on its uranium enrichment, another step back from commitments under a landmark deal with major powers in 2015 to curtail its nuclear programme that Trump abandoned in 2018.

In response, European signatories may launch a dispute resolution process against Iran this week that could lead to a renewal of the United Nations sanctions that were lifted as part of the deal, European diplomats said on Monday.

Diplomats said France, Britain and Germany could make a decision ahead of an EU foreign ministers' meeting on Friday that would assess whether there were any ways to salvage the deal.

After quitting the deal, the United States imposed new sanctions on Iran, saying it wanted to halt Iranian oil exports, the main source of government revenues. Iran's economy has been in freefall as the currency has plunged.

Trump adviser Kellyanne Conway said on Monday that he was still confident he could renegotiate a new nuclear agreement "if Iran wants to start behaving like a normal country."

Tehran has said Washington must return to the existing nuclear pact and lift sanctions before any talks can take place.

The United States advised American citizens in Israel and the Palestinian territories to be vigilant, citing the risk of rocket fire amid heightened tensions. As a U.S. ally against Iran, Israel is concerned about possible rocket attacks from Gaza, ruled by Iranian-backed Palestinian Islamists, or major Iran proxy Hezbollah in Lebanon.

Democratic critics of Trump have said the Republican president was reckless in authorising the strike, with some saying his threat to hit cultural sites amounted to a vow to commit war crimes. Trump also threatened sanctions against Iraq and said Baghdad would have to pay Washington for an air base in Iraq if U.S. troops were required to leave.

New Delhi, Jul 30: India's gold demand in 2020 is expected to fall to the lowest level in 26 years with domestic bullion prices hitting a record high and as falling disposable incomes could curtail retail purchases, the World Gold Council (WGC) said on Thursday.

Lower demand by the world's second-biggest bullion consumer could limit a rally in global prices, which hit a record high earlier this month, although it could also reduce India's trade deficit and support the ailing rupee.

"Fast rising gold prices could act as headwinds," said Somasundaram PR, the managing director of WGC's Indian operations.

Local gold futures have jumped 35% so far this year after rising a quarter in 2019.

India's gold consumption in the first half of 2020 plunged 56% on-year to 165.6 tonnes. Meanwhile, the coronavirus-triggered lockdown also slashed demand by 70% in the June quarter to 63.7 tonnes, the lowest in more than a decade, the WGC said in a report published on Thursday.

Millions of Indians have lost their jobs or taken a pay cut after the country imposed a lockdown on its 1.3 billion people to curb the spread of the virus that has infected more than 1.5 million Indians.

Consumption is generally high during the June quarter due to weddings and key festivals such as Akshaya Tritiya, but lockdown restrictions kept shoppers indoors this year.

The weak demand in the first half could drag down India's gold consumption in 2020 to the lowest since 1994, when demand stood at 415 tonnes, Somasundaram said, adding that it is still difficult to provide an estimate for full-year demand as the coronavirus crisis is still unfolding.

"Indian demand has previously jumped as much as 300 tonnes in a quarter. Latent demand could come out in the second half," Somasundaram said.

Pune/Mumbai, Feb 21: A BJP youth wing leader from Pune on Thursday submitted a complaint application to the police against AIMIM leader Waris Pathan for his controversial remarks made recently in Karnataka.

Pathan has claimed he has been quoted out of context.

Parismal Deshpande, a BJYM worker, submitted the written application at the Deccan Gymkhana police station, demading action against Pathan for allegedly promoting enmity between different groups and outraging religious feelings of a community.

Deshpande, in his complaint stated, that Pathan reportedly said "15 crore hai lekin 100 crore pe bhari hai' (We are 15 crore but we can dominate 100 crore).

"The statement by Pathan promotes violence and create a divide between two communities.

"Because of such statements, there are possibilities of atmosphere getting vitiated. Hence, he should be booked under IPC sections 153A (promoting enmity between different groups, 295A (outraging religious feelings), and 504 (provoking breach of the peace)," Deshpande said in the complaint.

An officer from the Deccan police station confirmed receiving the application.

Meanwhile, in Mumbai, the BJP slammed Pathan.

The saffron party on Thursday tweeted @BJP4Maharashtra saying, "Waris Pathan, who are you threatening to? Shiv Sena led government may tolerate your comments; but BJP and people of Maharashtra will teach you a lesson that your hate- mongering speeches will be shut."

However, Pathan has issued a statement to the media, saying he has been quoted out of context.

"I hereby wish to state that the media reports on TV channels showing my statement made in the public meeting at Gulbarga five days back have totally quoted me out of context," Pathan claimed on late Thursday evening.

"I wish to reiterate that I can never say anything intentionally or unintentionally that hurts the sentiments of any caste, community or gender. I am a proud Indian and respects the plurality of this country," he said.
