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.

Srinagar, Jun 30: On the deadly attack at Karachi Stock Exchange on Monday morning, a Kashmiri social activist and journalist warned that the incident is a stark reminder to all those in Pakistan supporting Jihad and attacked Pakistan prime minister Imran Khan for ignoring development agenda in Balochistan.

Yana Mir, the editor-in-chief of The Real Kashmir News, said, "Karachi Stock Exchange attack is a reminder to all those in Pakistan supporting Jihad. Remember @imrankhan that Youth is restless and they want development agenda. These young boys of BLA are also looking for a life which is settled and peaceful. Wake up Imran Khan and you Kashmiris also. Pakistan is going to finish you. Open your eyes."
Four heavily armed terrorists attacked the busy Pakistan Stock Exchange building in Karachi with grenades today, killing four security guards and a police officer before being shot dead in an exchange of fire, authorities said.

The terrorists, who arrived in a car, stormed the Karachi Stock Exchange building by firing indiscriminately and lobbed grenades at the main gate of the multi-storey building situated in the city's high-security commercial hub.

Balochistan is a well-known region rich in natural resources but the Balochis have always been deprived of basic facilities. No hospitals are available in Balochistan. If there are some then medical facilities and equipment are not available in hospitals. The education system is pathetic and similar is the case with the infrastructure: the roads, water system, agriculture and almost all fields of life.

It is pertinent to mention that enforced disappearances and abductions by the Pakistani military establishment have also been carried out regularly and for innumerable times in Balochistan. Leaders, activists, and vocal members of various student organizations have been detained by the security forces and kept in confinement. While others have been shot dead.

This crime against humanity has been going on for so long and so systematically in Balochistan that it has come to be considered as a normal state of affairs in the province. Many social and human rights activists have flagged the issue of oppression by the Pakistani establishment before the United Nations and other international agencies.

According to the Commission of Inquiry on Enforced Disappearances, an entity established by the Pakistani government, about 5,000 cases of enforced disappearances have been registered since 2014. Most of them are still unresolved.

Independent local and international human rights organisations put the numbers much higher. Around 20,000 have reportedly been abducted only from Balochistan, out of which more than 2,500 have turned up dead as bullet-riddled dead bodies, bearing signs of extreme torture.

Before being elected as Prime Minister, Imran Khan had admitted in multiple interviews about the involvement of Pakistan's intelligence agencies in enforced disappearances as well as extrajudicial killings and vowed to resign if he was unable to put an end to the practice, holding those involved responsible. But times have passed and only reports are available to narrate the true story.

Paris, Mar 2: A global agency says the spreading new virus could make the world economy shrink this quarter, for the first time since the international financial crisis more than a decade ago.

The Organization for Economic Cooperation and Development says Monday in a special report on the impact of the virus that the world economy is still expected to grow overall this year and rebound next year.

But it lowered its forecasts for global growth in 2020 by half a percentage point, to 2.4 per cent, and said the figure could go as low as 1.5 per cent if the virus lasts long and spreads widely.

The last time world GDP shrank on a quarter-on-quarter basis was at the end of 2008, during the depths of the financial crisis. On a full-year basis, it last shrank in 2009.

The OECD said China's reduced production is hitting Asia particularly hard but also companies around the world that depend on its goods.

It urged governments to act fast to prevent contagion and restore consumer confidence.

The Paris-based OECD, which advises developed economies on policy, said the impact of this virus is much higher than past outbreaks because "the global economy has become substantially more interconnected, and China plays a far greater role in global output, trade, tourism and commodity markets."

Jan 18: To mark the 30th anniversary of the mass exodus of Kashmiri Pandits from the Valley, members of the community took to social media to post videos of themselves by narrating the "Hum Aayenge Apne Watan" dialogue from an upcoming flick, 'Shikara', with the hope that they would return to their homeland one day.

On January 19, 1990, lakhs of Kashmiri Pandits were forced to leave their homes in the Valley following a genocidal campaign launched by the terrorists.

Theatre actor Chandan Sadhu participated in the campaign and said that Kashmiri Pandits have shown "unimaginable resilience" and hope to return to the Valley soon.

"As Kashmiri Pandits complete 30 years in exile this weekend, let our cry for justice be finally noticed. We have shown unimaginable resilience, and today we resolve to return home. Kashmiri Pandit friends: please record this video statement and put it up with #HumWapasAayenge," Sadhu tweeted.

The #HumWapasAayenge is trending on Twitter as more and more Kashmiri Pandits joined in the campaign to narrate the "Hum Aayenge Apne Watan" dialogue and a pledge to return to their homes.

Noted political commentator Sunanda Vashisht tweeted a throwback image of herself and said that resolve to go back home has strengthened more.

"I don't have many pictures left of my childhood. Choosing between life and family albums is really no choice at all. When lives were rescued, family albums got left behind. 30 years have passed. Resolve to go back home has only strengthened. #HumWapasAayenge," she tweeted.

Radio personality Khushboo Mattoo tweeted a video repeating the dialogue from Shikara and tweeted, "Said this in a BBC interview three years back. And I am saying it again #HumWapasAayenge #Shikara."

Journalist Rahul Pandita also took to his Twitter and captioned his post saying, "30 years of exile from Kashmir. Let us now pledge that we will return home."

'Shikara' chronicles the exodus of Kashmiri Pandits from the Valley on the night of January 19, 1990. Helmed by Vidhu Vinod Chopra, the movie is slated to release on February 7.

Netizens have supported the initiative and have expressed solidarity with the Kashmiri Pandits.

In July last year, Home Minister Amit Shah said in the Rajya Sabha that the central government is committed to bringing Kashmiri Pandits and Sufis back to the Valley saying a time will come when they will offer prayers at the famous Kheer Bhawani temple.

"Kashmiri Pandits were forced to leave Kashmir. Many of their shrines were demolished. Sufism was targeted in Jammu and Kashmir. Sufism used to talk about unity and harmony but they were attacked. No voice was raised in favour of Kashmiri Pandits and Sufis when they were brutally attacked. Sufis used to talk about the unity among Hindus and Muslims but they were forced to leave the Valley. Narendra Modi-led government is committed to bringing back Kashmiri Pandits, he had said.

The Mata Kheer Bhawani temple is one of the holiest shrines of Kashmiri Pandits, located about 14 kilometres east of Srinagar.

Last September, a delegation of the Kashmiri Pandit community met the Prime Minister in Houston and thanked him for the historic decision to abrogate Article 370 that gave special status to Jammu and Kashmir.

Modi acknowledged the hardships endured by the community following their exodus from their ancestral homeland back in 1989-1990 due to militancy.

"You have suffered a lot, but the world is changing. We have to move ahead together and build a new Kashmir," the Prime Minister had told the delegation.

"I had a special interaction with Kashmiri Pandits in Houston," Modi had tweeted following the interaction.

In October, Union Minister Prakash Javadekar announced that the Centre has decided to provide compensation of Rs 5.5 lakh each to 5,300 displaced families from Pakistan-occupied Kashmir (PoK), who initially opted to move outside Jammu and Kashmir but later on returned.

These families were earlier left out in the rehabilitation package that was approved by the Cabinet on November 30, 2016.

The Prime Minister had announced a reconstruction plan for Jammu and Kashmir in November 2016. His plan included a rehabilitation package for a one-time settlement of 36,384 displaced persons' (DPs) families of PoK-1947 and Chhamb.
