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.

New Delhi, May 24: New rules for domestic travel during the lockdown were released by the government today, including advising passengers to download the Aarogya Setu application on their mobile devices and asking states to ensure thermal screening at departure point of airports, railway stations and bus terminals. The guidelines were shared by Civil Aviation Minister Hardeep Singh Puri, who also shared new rules for international travel.

The minister had recently said that international flight operations may start by mid-June or end-July if the COVID-19 virus "behaves in a predictable manner".

"Prescribed clinical protocol will be followed in case any domestic or international traveller shows symptoms of COVID-19. States can also develop their own protocol for quarantine and isolation as per their own assessment," Mr Puri said.

The guidelines come a day before the resumption of air travel after nearly two-months hiatus following lockdown to prevent the spread of coronavirus.

The Indian Railways has also issued a list of 100 pairs of trains that it will operate from June 1, putting in operation popular trains such as Durontos, Sampark Krantis, Jan Shatabdis and Poorva Express.

Dos and Don'ts shall be provided along with tickets to travellers by agencies concerned, said the Health Ministry's guidelines for domestic travel (air/train/inter-state bus travel).

Latest guidelines on domestic & international travel have been issued by @MoHFW_INDIA.

I hope travellers strictly follow these self-regulatory norms & strengthen India's hands in this fight against COVID19. Remember, each one of us is a soldier against the pandemic.@MoCA_GoIpic.twitter.com/xVbTG1K44n

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.

Soon, you may be able to withdraw cash from an ATM without touching any part of the machine. AGS Transact Technologies, a provider of cash and digital payment solutions and automation technology, on Monday said it has successfully developed and tested a touchless ATM solution in light of the COVID-19 pandemic.

The ‘contactless' solution, currently under demo at interested banks, enables a customer to perform all the steps required to withdraw cash from an ATM using the mobile app itself. 

The customer simply has to scan the QR code displayed on the ATM screen and follow the directions on their respective bank's mobile application. 

This includes entering the amount and mPIN required to dispense the cash from the ATM machine. 

According to the company, the QR code feature makes cash withdrawals quicker and more secure, and negates the chances of compromising the ATM Pin or card skimming.

"The new Touchless ATM solution is an extension of the flagship QR Cash solution which ensures safety of the users and will provide a seamless cash withdrawal experience with enhanced security," said Ravi B. Goyal, Chairman and MD, AGS Transact Technologies Ltd.

With minimum investment, the banks can enable this solution for their ATM networks by upgrading the existing software.

AGSTTL has so far installed, maintained and managed a network of over 72,000 ATMs across the country and also provides customised solutions to leading banks. 

The company earlier introduced UPI-QR based Cash withdrawal solution in partnership with Bank of India. 

This is how the solution works.

Open the Bank mobile application on your smartphone and select QR Cash Withdrawal. Enter the amount you wish to withdraw on the mobile app and scan the QR code on the ATM screen.

Next, confirm the amount by clicking on ‘proceed' in the app and enter the mPin to authenticate the transaction. Now collect the cash and receipt and you are done.

"The seamless, cardless and touchless withdrawal method is designed to provide easy transaction flow, without the need to touch the ATM screen or enter the pin," said Mahesh Patel, President and Group Chief Technology Officer, AGS Transact Technologies.
