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.

According to sources quoted by PTI news agency, the MEA told the  Pakistan's Charge d'affaires to India that the responsibility of safety and security of Indian personnel in Islamabad "lays squarely with Pakistani authorities."

"Pakistan was asked to ensure return of two Indian officials along with official car to Indian High Commission in Islamabad immediately," sources added. 

The incident comes after two Pakistani officials at the Pakistani High Commission in New Delhi were accused of espionage and deported.

The two officials have been missing since Monday morning. Officials said the issue has been taken up with the Pakistan government.

Earlier, a vehicle of India's Charge d'affaires Gaurav Ahluwalia was chased by Inter-Services Intelligence (ISI) member.

In March, the Indian High Commission in Pakistan sent a strong protest note to the foreign ministry in Islamabad protesting against the continuing harassment of its officers and staff by Pakistani agencies.

Washington D.C., Jan 20: An American bride asked for money from her invitees so that they can be on the 'exclusive guest list'.

Weddings can be surely expensive. But is it feasible for one to charge the guests to make up for the expenses?

According to Fox News, that is exactly what happened in a recent American wedding. A 19-year-old shared on Reddit that her cousin was getting married on Sunday and announced that she would charge 50 dollars to those who wanted to attend her wedding.

"She said that they can Venmo her money so there won't be no [sic] problems and everyone who paid will be added onto the 'exclusive guest list' which basically means you won't have to wait in line while other guests pay," wrote the user named DaintySheep.

While she refused to pay for entry into her cousin's wedding the bride-to-be contacted the elders in the family which ended up in an embarrassing situation.

"She wanted to get the money she spent on her special day back. I told her I wouldn't be able to come because this was outrageous and that I wish her well on her special day. She contacted my aunt and my aunt called me cheap and rude. My parents offered to pay for my entry, but I refused," continued the disheartened girl.

While in almost every nook and cranny of the world gifting the bride-groom with money is a tradition, asking for money from friends and family to replenish the money spent on a wedding is can be said to be a rare scenario.

New Delhi, Feb 5: Over five crore farmers were yet to get the third instalment of money under the Centre's ambitious PM-Kisan scheme, aimed at providing direct support of Rs 6,000 annually to them, according to the latest Ministry of Agriculture and Farmers' Welfare data.

The total amount of the scheme, which came into effect on December 1, 2018, is to be paid in three equal instalments of Rs 2,000 every four months.

The data showed about 2.51 crore farmers have not got even the second instalment and 5.16 crore of them were yet to get the third instalment.

Over 9 crore farmers have registered themselves under the scheme between December 2018 and November 2019, it said.

Of these, 7.62 crore or 84 per cent of farmers have received the first instalment.

The money through the second instalment was given to nearly 6.5 crore farmers and the amount under the third instalment was given to 3.85 crore beneficiaries, according to the data received in response to an RTI query filed by this PTI journalist.

The agriculture ministry, in its response, gave three sets of data mentioning the benefits given to farmers under the scheme between December 2018 and November 2019.

It said 4.74 crore farmers were registered between December 2018 and March 2019.

Of them, 4.22 crore received the first instalment, 4.02 crore the second and 3.85 crore the third.

There was no mention why nearly 50 lakh, 70 lakh and 90 lakh registered farmers during this period did not get the first, second and third instalment respectively.

There was no registered beneficiary in West Bengal and Sikkim, hence no amount was disbursed during this period, according to the data.

Giving details of the 3.08 crore farmers registered between April and July last year, it said 2.66 crore and 2.47 crore beneficiaries have got their first and second instalments respectively.

The RTI reply did no mention why around 40 lakh and 61 lakh registered farmers during this period did not get their first and second instalment respectively.

"The beneficiaries are eligible for the instalment for the period in which he/she gets registered and subsequent periods, thereafter. Therefore, the third instalment is not due for the beneficiaries registered in the period April 2019-July 2019," the ministry said.

There was no registered beneficiary during this period in West Bengal, Punjab and Chandigarh and therefore nobody was paid first and second instalments.

The ministry said around 1.19 crore beneficiaries were registered between August and November 30, 2019, of these nearly 73.66 lakh farmers have been given the first instalment.

There was no mention of payment of first instalment to over 45 lakh eligible beneficiaries during the period.

"The beneficiaries are eligible for the instalment for the period in which he/she gets registered and subsequent periods, thereafter. Therefore, the second and third instalments are not due for the beneficiaries registered in the period August 2019 to November 2019," it said.

The ministry was asked to provide the total number of farmers, state-wise, and the amount received by them under the Pradhan Mantri Kisan Samman Nidhi or PM-Kisan scheme.

"PM-Kisan Samman Nidhi scheme has been implemented from December 1, 2018. It is stated that PM-Kisan is a continuous and ongoing scheme, in which the financial benefits are transferred to the bank accounts of the identified beneficiaries as and when their correct and verified data is uploaded by the concerned states/union territories on PM-Kisan web portal," the ministry said in the RTI response vide its letter dated December 26, 2019.

The data of beneficiaries so uploaded by them undergoes a multi-level verification, including by banks, and only then the amount is released to the beneficiary, it said, adding that www.pmkisan.gov.in website can be accessed to get more details on the operational guidelines of the scheme.

According to the data updated on the website on February 3, around 8.82 crore farmers have been registered and 8.41 crore have received the first installment, 7.56 crore the second instalment, 6.19 crore the third and 3.03 crore have received the fourth installment.
