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.

London, Feb 14: Liquor tycoon Vijay Mallya once again asked the Indian banks to take back 100 per cent of the principal amount owed to them at the end of his three-day British High Court appeal on Thursday against an extradition order to India.

The 64-year-old former Kingfisher Airlines boss, wanted in India on charges of fraud and money laundering amounting to an alleged Rs 9,000 crores in unpaid bank loans, said the Enforcement Directorate (ED) and the Central Bureau of Investigation (CBI) are fighting over the same assets and not treating him reasonably in the process.

“I request the banks with folded hands, take 100 per cent of your principal back, immediately,” he said outside the Royal Courts of Justice in London.

“The Enforcement Directorate attached the assets on the complaint by the banks that I was not paying them. I have not committed any offenses under the PMLA (Prevention of Money Laundering Act) that the Enforcement Directorate should suo moto attach my assets," he said.

"I am saying, please banks take your money. The ED is saying no, we have a claim over these assets. So, the ED on the one side and the banks on the other are fighting over the same assets,” he added.

Asked about heading back to India, he noted: “I should be where my family is, where my interests are.

"If the CBI and the ED are going to be reasonable, it’s a different story. What all they are doing to me for the last four years is totally unreasonable.”

Lord Justice Stephen Irwin and Justice Elisabeth Laing, the two-member bench presiding over the appeal, concluded hearing the arguments in the case and said they will be handing down their verdict at a later date after considering the oral as well as written submissions in the “very dense” case over the next few weeks.

On a day of heated arguments between Mallya’s barrister, Clare Montgomery, and Crown Prosecution Service (CPS) counsel Mark Summers, arguing on behalf of the Indian government, both sides clashed over the prima facie case of fraud and deception against Mallya.

“We submit that he lied to get the loans, then did something with the money he wasn’t supposed to and then refused to give back the money. All this could be perceived by a jury as patently dishonest conduct,” said Summers.

“What they [Kingfisher Airlines] were saying [to the banks] about profitability going forward was knowingly wrong,” he said, as he took the High Court through evidence to counter Mallya’s lawyers’ claims that Westminster Magistrates Court Judge Emma Arbuthnot had fallen into error when she found a case to answer in the Indian courts against Mallya.

Mallya, who remains on bail on an extradition warrant, is not required to attend the hearings but has been in court to observe the proceedings since the three-day appeal opened on Tuesday. A key defence to disprove a prima facie case of fraud and misrepresentation on his part has revolved around the fact that Kingfisher Airlines was the victim of economic misfortune alongside other Indian airlines.

However, the CPS has argued that “there is enough in the 32,000 pages of overall evidence to fulfil the [extradition] treaty obligations that there is a case to answer”. “There is not just a prima facie case but overwhelming evidence of dishonesty… and given the volume and depth of evidence the District Judge [Arbuthnot] had before her, the judgment is comprehensive and detailed with the odd error but nothing that impacts the prima facie case,” said Summers.

At the start of the appeal, Mallya’s counsel claimed Arbuthnot did not look at all of the evidence because if she had, she would not have fallen into the multiple errors that permeate her judgment. The High Court must establish if the magistrates’ court had in fact fallen short on a point of law in its verdict in favour of extradition.

Representatives from the Enforcement Directorate (ED) and Central Bureau of Investigation (CBI), as well as the Indian High Commission in London, have been present in court to take notes during the course of the appeal hearing.

Mallya had received permission to appeal against his extradition order signed off by former UK home secretary Sajid Javid last February only on one ground, which challenges the Indian government's prima facie case against him of fraudulent intentions in acquiring bank loans.

At the end of a year-long extradition trial at Westminster Magistrates’ Court in London in December 2018, Judge Arbuthnot had found “clear evidence of dispersal and misapplication of the loan funds” and accepted a prima facie case of fraud and a conspiracy to launder money against Mallya, as presented by the CPS on behalf of the Indian government.

Mallya remains on bail since his arrest on an extradition warrant in April 2017 involving a bond worth 650,000 pounds and other restrictions on his travel while he contests that ruling.

Jakarta, Mar 15: Indonesia's transport minister is in intensive care after testing positive for the novel coronavirus, an official has said, as schools and tourist attractions were ordered to close over the health threat.

Transportation Minister Budi Karya Sumadi was receiving treatment at an army hospital in Jakarta, State Secretary Pratikno said on Saturday.

A hospital spokesman said Sumadi was encountering difficulty breathing but that his condition was improving.

Pratikno said Sumadi was involved in virus mitigation efforts, particularly the evacuation of Indonesians from epicenters of the outbreak, and that President Joko Widodo had called for tests to be carried out on other ministers.

Cases of the virus in Indonesia, the world's fourth most populous country, have jumped from zero two weeks ago to 96, with five deaths, according to government spokesperson Achmad Yurianto.

He also said the virus has spread outside Greater Jakarta to Bandung in West Java, Solo in Central Java, Manado in North Sulawesi, Pontianak in West Kalimantan, as well as holiday havens Yogyakarta and Bali.

Following the increase, the government on Saturday established a task force on COVID-19 mitigation.

Jakarta's Governor Anies Baswedan announced that schools would close for two weeks starting Monday, and ordered the closure of city-owned tourist attractions, such as Ragunan Zoo and Ancol beach.

He emphasized that Jakarta would not be locked down but urged people "to be responsible" and called for social distancing when possible.

Similarly, the administration of Solo, Central Java, Friday announced that schools and tourist attractions would close after a coronavirus patient died in the region.

The World Health Organization has said it is particularly concerned about high-risk nations with weaker health systems, which who may lack the facilities to identify cases.

A day after declaring the coronavirus outbreak to be pandemic this week, WHO chief Tedros Adhanom Ghebreyesus called Indonesia's president Widodo and both agreed to "scale up cooperation."

Washington, Jun 6: Washington mayor Muriel Bowser on Friday renamed an area near the White House that has become the epicenter of anti-racism protests over the past week "Black Lives Matter Plaza" -- unveiling a giant street mural.

But in so doing, the African-American mayor piqued the ire of the very movement she was supporting, as well as of President Donald Trump.

The protests are focused on the May 25 death in Minneapolis of 46-year-old black man George Floyd while in police custody. A white officer kneeled on his neck until he lost consciousness.

That officer and three others are now in custody and facing charges -- second-degree murder for the kneeling officer, and aiding and abetting that crime for his colleagues.

Just north of the White House, the words BLACK LIVES MATTER were painted in huge yellow letters along the street leading to the presidential mansion, along with the symbol from the DC flag.

"The section of 16th street in front of the White House is now officially 'Black Lives Matter Plaza'," Bowser tweeted.

A city worker put up a new street sign with the name.

"Determination to make America the land it ought to be," she said on Twitter.

The corner of 16th and H is significant -- in a controversial incident on Monday, peaceful protesters gathered there were dispersed with tear gas.

Shortly afterwards, Trump walked from the White House to a nearby church for a photo op, during which he held the Bible in his hand.

"There was a dispute this week about whose street this is. Mayor Bowser wanted to make it abundantly clear that this is DC's street and to honor demonstrators" who protested on Monday, her chief of staff John Falcicchio tweeted.

Rose Jaffe, one of the artists in the collective that painted the BLACK LIVES MATTER sign, told AFP it was "about reclaiming the streets of DC."

But she added that Bowser "has to do more than just a photo-op -- she must carry on when this is washed away" on issues like police accountability.

Stars Like LeBron James praised her move on Twitter, but the local chapter of the Black Lives Movement balked, calling the mural a "performative distraction from real policy changes."

"This is to appease white liberals while ignoring our demands," it said on Twitter, saying Bowser had "consistently been on the wrong side" of the movement.

'We are well equipped'

The US government deployed a significant contingent of federal officers and National Guard troops from other states -- many of them not wearing any identifying garb or badges -- to handle protests in Washington.

Bowser had called up the local Guardsmen but the Justice Department moved to take partial control of peacekeeping, with Guard troops from as far away as Utah brought in.

In a letter to Trump dated Thursday and tweeted early Friday, Bowser called for "all extraordinary federal law enforcement and military presence" to be removed.

She said their deployment was "inflaming demonstrators and adding to the grievances of those who, by and large, are peacefully protesting for change and for reforms to the racist and broken systems that are killing black Americans."

"These additional, unidentified units are operating outside of established chains of command," she added.

"We are well equipped to handle large demonstrations and First Amendment activities," including the right to assemble, Bowser said.

Trump reiterated on Friday that authorities need to "dominate the streets," and has been unapologetic about the deployment of forces.

And on Twitter, he lashed out at Bowser, calling her "incompetent" and saying the National Guard had saved her from "great embarrassment."

Senator Mike Lee of Utah accused Bowser of evicting Utah National Guard members from area hotels.

She replied: "DC residents cannot pay their hotel bills. The Army can clear that up with the hotel today, and we are willing to help."
