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.

Bhopal, Mar 13: The Madhya Pradesh Economic Offences Wing (EOW) on Thursday decided to verify facts afresh in a complaint against former Union Minister Jyotiraditya Scindia and his family, in which they are accused of falsifying a property document while selling land.

The development came after Mr Scindia quit the Congress and joined the BJP on Wednesday. 22 MLAs who belong to his camp also resigned, threatening the survival of the Kamal Nath government in the state.

"Yes, an order has been given for re-verification of facts in the complaint filed by Surendra Shrivastava," an Economic Offences Wing official told PTI.

An EOW release said Mr Shrivastava on Thursday filed a new complaint against Mr Scindia and his family, alleging that by falsifying a registry document, they sold him a piece of land at Mahalgaon which was smaller by 6,000 sq feet than the original agreement in 2009.

He had lodged the complaint first on March 26, 2014. But it was investigated and closed in 2018, the EOW official said. "As he again petitioned us today, we will re-verify the facts," the officer said.

Jyotiraditya Scindia's close aide Pankaj Chaturvedi alleged that it was political vendetta.

"The case had been closed for want of evidence. Now for vengeance, it is being reopened. We have full faith in the Constitution and law. We will get justice and Kamal Nath government a befitting reply," Mr Chaturvedi said.

New Delhi, Jan 28: Stepping up attack on Chief Minister Arvind Kejriwal, Union Home Minister Amit Shah on Monday dared the AAP chief to visit the anti-CAA protest site at Shaheen Bagh so that the people of Delhi can decide whom to vote for in the assembly election.

Addressing a rally in Rithala in northwest Delhi, Shah said Kejriwal and Congress leader Rahul Gandhi were against the construction of Ram temple, the scrapping of provisions of Article 370 and not bothered about the country's image and soldiers.

The opposition fears that they will upset their vote bank, he said and asked, "Are you their vote bank? Where is their vote bank?" To this, the crowd replied, "Shaheen Bagh".

The BJP leader claimed that the Delhi Police has booked Sharjeel Imam, a JNU student, on the charge of sedition for his comment of "trying to cut chicken's neck" and breaking the North East from the rest of the country.

"I want to ask Kejriwal whether he is in favour of apprehending Sharjeel Imam or not? Whether you are with the people of Shaheen Bagh or not, please tell the people of Delhi," Shah said.

Imam was one of the initial organisers of the Shaheen Bagh protest.

Hitting back at the BJP, Kejriwal alleged that the saffron party does not want to open the Shaheen Bagh stretch of the Kalindi Kunj road as it is doing "dirty politics" over it.

He said law and order in the national capital lies entirely with the Centre and "if they are saying that they need permission from me, I am giving them permission, open the road in one hour".

"I can give it to you in writing, the BJP does not want to open the route in Shaheen Bagh. The Shaheen Bagh route will remain closed till February 8 (election day) and it will open February 9," Kejriwal told reporters.

Calling Kejriwal a member of the 'tukde tukde' gang, a term used by the BJP to attack groups it accuses of working to promote violent leftists and separatism, Shah sought to return fire and said the protesters of Shaheen Bagh will not listen to his party.

"They will not listen to us. You people (AAP leaders) say that you are with Shaheen Bagh, if you have the guts then go and sit with them and let Delhi decide," Shah said.

At another election rally in Janakpuri, Shah accused Gandhi and Kejriwal of doing politics of "vote bank" on national issues and "supporting" the protest at Shaheen Bagh while instigating riots and vandalism.

"The Modi government will not spare anti-national elements," he warned.

Upon mentioning the recent Supreme Court judgment on Ayodhya, Shah was greeted with cheers and chants of 'Jai Shri Ram'.

The home minister further said that this was the first Republic Day in Jammu and Kashmir after the abrogation of Article 370 and the tricolour was unfurled there with enthusiasm and without any bloodshed.

The former BJP president also attacked the Kejriwal government for not fulfilling promises like regularising temporary employees, providing free wifi, opening new schools and colleges, constructing roads and cleaning the Yamuna.

"Kejriwal government is in power since five years but till today there is no clean drinking water in the city. There are no good schools or hospitals as claimed by him. When I visited a Delhi government school, I saw that it was operating from a building that was illegally built and falls in the list of those that to be erased," Shah said.

He claimed that Kejriwal came to power with the help of Anna Hazare's anti-corruption movement but "completely changed" later on.

"He had said that he would not take any government accommodation or vehicles and other facilities but after becoming chief minister he availed all these facilities," Shah said.

He also slammed the Delhi government for not sanctioning the prosecution of former JNU students' union leader Kanhaiya Kumar in a sedition case.

Shah said if the national capital comes under the leadership of Modi, it will become the best city in the world.

The BJP has a vision for development of Delhi and cleaning the Yamuna river will be on top of our agenda, he said.

"Yamuna river is still dirty as against his (Kejriwal) claims of cleaning the river... Modi and Yogi (Adityanath) have cleaned Ganga river as promised. We will make Yamuna Riverfront like Sabarmati riverfront in Ahmedabad," Shah said.

However, a sizeable majority of those present at the public meeting was not convinced by the claims and promises made by Shah.

Bablu Yadav, a migrant and resident of Janakpuri said, "Shah and Modi can only talk but Kejriwal knows how to perform. They keep raking up issues like Ayodhya, Kashmir, Muslims and Pakistan... what are they waiting for if they want to attack Pakistan? They are in power, so why don't they destroy it instead of telling us how wrong Pakistan is?"

Another local Deepak Shrivastava who attended the Janakpuri meeting said, "All we hear from Modi and Shah are pep talks. I am an engineer from BHU and searching for a job. This government has failed the country's youth."

"Now, they have a problem with protests in universities but it is the same youth who brought them to power in 2014. The same youth will ensure their defeat," he added.

The public meeting in Janakpuri witnessed two incidents of pick-pocketing as the thieves managed to steal Rs 37,500 in cash and a mobile phone, police said.

Singapore, Mar 23: Oil prices fell at the open in Asia on Monday after a trillion-dollar Senate proposal to help the coronavirus-hit American economy was defeated and death tolls soared across Europe and the US.

US benchmark West Texas Intermediate initially tumbled more than three percent but then pulled back some ground to trade 1.5 percent lower, at $22 a barrel.

Brent crude, the international benchmark, fell 4.9 percent to $25 a barrel.

Prices have fallen to multi-year lows in recent weeks as lockdowns and travel restrictions to fight the virus hit demand, and top producers Saudi Arabia and Russia engage in a price war.

The latest drop came after a trillion-dollar Senate proposal to rescue the US economy was defeated after receiving zero support from Democrats, and with five Republicans absent from the chamber because of virus-related quarantines.

The bill had proposed funding for American families, thousands of shuttered or suffering businesses and the nation's critically under-equipped hospitals.

Coronavirus deaths soared across Europe and the United States at the weekend despite heightened restrictions.

The death toll from the virus -- which has upended lives and closed businesses and schools across the planet -- surged to more than 14,300 Sunday, according to an AFP tally.

AxiCorp chief markets strategist Stephen Innes said that "total demand devastation" had set it.

"Oil markets collapsed out of the gate this morning as prices react... to stringent containment lockdown measures," he said.
