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.

Washington, Feb 16: India and the United States share "unshakeable" ties, said US Principal Deputy Assistant Secretary (PDAS), Alice Wells, on Sunday, adding that the upcoming visit of President Donald Trump will further strengthen the relationship between the two countries.

"The U.S. and #India enjoy a close partnership that grows stronger day by day. Together, we are breaking records. For example, we welcomed a record number of Indian exchange students to the US last year and hope to receive even more this year," said Bureau of South and Central Asian Affairs in a tweet attributed to Alice Wells.

"The ties between our countries are unshakeable, and we look forward to an even warmer relationship as @narendramodi hosts @POTUS later this month," it added.

Trump will pay a two-day state visit to India from February 24 at the invitation of Prime Minister Narendra Modi.

"India is at the heart of the Indo-Pacific region and plays an increasingly prominent role on the world's stage. The U.S. looks forward to partnering with #India at every step of the way, " Alice Wells further said.

According to the Ministry of External Affairs (MEA), Trump is expected to attend an event at the Motera Stadium in Ahmedabad on the lines of the ''Howdy Modi'' function that was addressed by the US President and PM Modi in Houston in September last year. Trump is slated to pay a two-day visit to India from February 24.

During the visit, Trump, who will be accompanied by First Lady Melania, will attend official engagements in New Delhi and Ahmedabad, and interact with a wide cross-section of the Indian society, the MEA said in a statement.

The announcement of Trump's first official visit to India was earlier made by the White House on Monday, which, in its statement, said that the US President and Modi had agreed during a recent phone conversation that the trip will "further strengthen the United States-India strategic partnership and highlight the strong and enduring bonds between the American and Indian people".

Mumbai, Jul 30: Counterfeiting incidents have increased 24 per cent in the country in 2019 over the previous year, creating an over Rs 1 lakh crore hole in the economy, according to a report.

The report also said counterfeiters are having a free run due to the pandemic-driven disruptions to organised supply chains and the resultant spike in consumer demand.

According to the report by ASPA, a self-regulated industry body of anti-counterfeiting and traceability solutions providers, counterfeiting has risen steadily in the last few years, and exploiting the pandemic as a cover for their activities.

Between February and April 2020, over 150 incidents of counterfeiting cases were reported, mostly about fake PPE kits, sanitisers and masks taking advantage of the high demand for these products, it noted.

"There was a 24 per cent increase in counterfeiting in 2019 over 2018, leading to the loss of more than Rs 1 lakh crore to the overall economy," said Nakul Pasricha, president of Authentication Solution Providers Association.

The association works with global authorities like the International Hologram Manufacturers Association, Counterfeit Intelligence Bureau of the Interpol, and domestic industry lobbies like Ficci, he said.

Counterfeiting is a universal issue and is 3.3 per cent of global trade, according to the OECD data, impacting social and economic development across the world.

The report lists the currency, FMCG, alcohol, pharma, documents, agriculture, infrastructure, automotive, tobacco, lifestyle and apparel, as the 10 sectors impacted most by counterfeiting.

Among these, currency, alcohol and FMCG continue to be the top three sectors with the highest counterfeiting in the last two years. The FMCG sector is most vulnerable, as counterfeit incidents rose 63 per cent between 2018 (79) and 2019 when the reported cases jumped to 129.

Within the states, the fakers have a free run in Uttar Pradesh, Bihar, Rajasthan, Madhya Pradesh, Bengal, Punjab, Jharkhand, Delhi, Gujarat, and Uttarakhand, calling for urgent actions to frame anti-counterfeiting policy measures.

According to the report, UP continues to be on top followed by Bihar, Rajasthan, and together these three states represent almost 45 per cent of all counterfeiting reported in the last two years.

What is more alarming is that counterfeiting is not limited to high-end luxury items today, as common everyday items as fake cumin seeds, mustard cooking oil, ghee, hair oils, soaps, baby care vaccines and medicines are aplenty in the markets.

"There is an urgent need for building and nurturing authentication ecosystems in the country with the active involvement and active participation of all stakeholders," said Pasricha.

New Delhi, Jun 29: A disturbing video of a Covid-19 patient, speaking his last words, after his oxygen supply was allegedly cut off, has surfaced on social media. The patient reportedly died after indicating that the oxygen supply to him was cut off despite his requests.

The video has a 35-year-old Covid-19 patient bidding good-bye to his family, from a government hospital bed in Hyderabad. The patient Ravi Kumar can be seen speaking out against the negligence of of the medical staff in providing ventilator support to him when he needed it the most.

The video has led to social media outrage as it attracted public attention towards plight of patients in government hospitals

"I am not able to breathe, I pleaded but they did not continue oxygen for the last three hours. I am not able to breathe anymore daddy, it's like my heart has stopped, Bye daddy. Bye to all, daddy," these were apparently the final words of the man, who spoke in his local dialect, and shared on social media.

Several reports have claimed that the man had been admitted to government Chest hospital, after several private hospitals refused to admit him. His ventilator support was allegedly taken off in the hospital, after which he recorded the video message.

The victim’s family shared the video message for the public to know of the negligence.

Reports have it that Ravi’s covid-19 report, which testes positive, was given to family a day after his death, when 30 of his family members performed the final rites, thus making all of them vulnerable to the virus. Ravi’s father has alleged that the test was done on June 24 and Ravi died on June 26, while the report was given to them on June 27.
