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.

Mar 11: In a bid to keep its flock together, the crisis-hit Madhya Pradesh Congress has decided to shift its 92 MLAs either to Jaipur or some other place.

The move comes after 22 Congress MLAs loyal to former Union minister Jyotiraditya Scindia resigned on Tuesday, pushing the 15-month-old Kamal Nath government to the brink of collapse.

"We are going to take our 92 MLAs and those supporting our Madhya Pradesh government to a hotel," a senior Congress leader said on Wednesday.

The legislators would be taken either to Jaipur or some other Congress-ruled state like Chhattisgarh, a party source said.

Apart from its own MLAs, the Congress is also keeping a close watch on four Independents who are supporting the party-led state government.

On Tuesday, 22 Congress MLAs from Madhya Pradesh resigned soon after Scindia quit the party.

The development reduced the Congress government in the state to minority.

The state Congress unit is now making all efforts to save the Kamal Nath-led government.

The BJP on Tuesday night shifted its MLAs to Manesar at Gurugram in Haryana, sources in the saffron party said.

The Congress, whose tally before the rebellion was 114, has a wafer-thin majority in the Madhya Pradesh Assembly whose current effective strength is 228.

It also has the support of four Independents, two BSP legislators and one SP MLA, but some of them are now likely to switch sides to the BJP.

The BJP has 107 seats in the state Assembly.

Karachi, May 29: Investigators and rescue officials have found around Rs 3 crore in cash in the wreckage of the Pakistan International Airlines' aircraft that crashed wth 99 people on board, killing 97 people, including nine children.

Flight PK-8303 from Lahore to Karachi crashed in a residential area near Karachi International Airport on Friday, with only two passengers miraculously surviving the crash.

Investigators and rescue officials have found currencies of different countries and denominations worth around Rs 30 million from the aircraft's wreckage, an official said on Thursday.

"An investigation has been ordered into how such a huge amount of cash got through airport security and baggage scanners and found its way into the ill-fated flight," the official said.

He said that the amount was recovered from two bags in the wreckage.

"The process of identifying the bodies and their luggage which will be handed over to their families and relatives is going on," he said.

A total of 97 people including the aircraft crew died in the crash, one of the most catastrophic aviation disasters in Pakistan's history.

A government official said on Thursday that the identification of 47 bodies had been completed, while 43 bodies were handed over for burial.

Friday's accident was the first major aircraft crash in Pakistan after December 7, 2016 when a PIA ATR-42 aircraft from Chitral to Islamabad crashed midway. The crash claimed the lives of all 48 passengers and crew, including singer-cum-evangelist Junaid Jamshed.
