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.

Social media platform WhatsApp assured the Supreme Court on Wednesday that it will not roll out its payment services without complying with all payment regulations and norms in the country.

A bench headed by Chief Justice S.A. Bobde and comprising Justices Indu Malhotra and Hrishikesh Roy took up the matter through video conferencing. Senior advocate Kapil Sibal, representing the social media platform, said "WhatsApp Inc makes a statement on behalf of his client that they will not go ahead with the payments' scheme without complying with all the regulations in force."

The statement was made during the hearing of a petition seeking a ban on payment through WhatsApp, as it does not conform to the data localization norms. The top court took the assurance made by WhatsApp on record.

WhatsApp made the statement during the hearing of a plea seeking a ban on its payment service, for not being in line with data localization norms.

In 2018, WhatsApp was granted a beta licence to launch its payment service, but a dedicated and separate app is yet to be launched. A petition was moved in the apex court that WhatsApp's existing model for its payments service should be declared inconsistent with the Unified Payment Interface (UPI) Scheme, as a separate dedicated app has not been offered by the company.

The petitioner NGO, Good Governance Chambers, argued that the National Payments Corporation of India (NPCI) and the Reserve Bank of India (RBI) must change its model on the lines of the UPI payment scheme, and its operations may be suspended until these conditions are met.

The apex court today asked the Centre, Facebook and WhatsApp to file their replies within three weeks and it will take up the matter thereafter. The court noted that the government may process the applications filed by WhatsApp in accordance with the law and there is no stay on the same. Facebook was represented by senior advocate Arvind Datar.

The petitioner argued that lapses have been found in relation to WhatsApp's claims of having a secure and safe technological interface for securing sensitive user data.

Jan 24: India’s economy appears to be shaking off a slump, as activity in the services and manufacturing sectors expanded for a second straight month in December.

The needle on a gauge measuring so-called animal spirits signaled the economy may be taking a turn for the better, as five of the eight high-frequency indicators tracked by Bloomberg News came in stronger last month. The dial was last at the current position in August.

“Animal spirits” is a term coined by British economist John Maynard Keynes to refer to investors’ confidence in taking action, and the gauge uses the three-month weighted average to smooth out volatility in the single-month numbers.

The nascent recovery would need a helping hand, with expectations building that Finance Minister Nirmala Sitharaman will provide some stimulus when she presents the budget Feb. 1. Official forecasts show the economy is set to expand at 5% in the year ending March 2020 -- the weakest pace in more than a decade.

Here are the details of the dashboard:

Business Activity

The dominant services index rose to the highest level in five months in December as improving new work orders helped boost activity. The seasonally adjusted Markit India Services PMI index climbed to 53.3 from 52.7 in November, helping post a strong end to the calendar year.

India’s manufacturing PMI also rose -- to 52.7 from 51.2 a month ago -- boosted by the fastest increase in new orders since July. A reading above 50 means expansion while anything below that signals contraction.

The uptick in business confidence was accompanied by a rise in inflationary pressures, the survey showed. That trend may keep monetary policy makers from resuming interest-rate cuts anytime soon, leaving most of the heavy-lifting to boost growth with the government.

“The relative stability in macro indicators over the past two months suggests that the worst is behind, but the recovery is likely to be prolonged,” said Teresa John, an economist at Nirmal Bang Equities Pvt. in Mumbai. “Still, sluggish growth and rising inflation indicate that India may well remain in stagflation for most of 2020.”

Exports

Exports remained a laggard, falling 1.8% in December from a year ago. The drag was mainly because of a fall in export of engineering goods, which constitute a third of India’s non-oil exports.

Capital goods imports continued to contract and was lower by 16.5% year-on-year in December after a 22% drop in November. This was the seventh consecutive month of continuous decline, underscoring the weakness in the capex cycle, according to IDFC First Bank.

Consumer Activity

Weakness in demand for passenger vehicles persisted, with local sales falling 1.2% in December from a year ago, according to the Society of Indian Automobile Manufacturers. That capped the worst yearly passenger vehicle sales on record. A Nielsen study on demand for fast-moving consumer goods showed volume growth dropped to 3.5% in the last quarter of 2019 from 3.9% in the same period of 2018.

Funding conditions held out hope, showing considerable improvement in December, according to the Citi India Financial Conditions Index. Credit growth remained tardy though, with demand for loans rising at a slower 7.1% pace from a year ago compared with a nearly 8% growth in November.

Industrial Activity

Industrial output rose for the first time in four months in November. The pick up was broad-based, led by mining, manufacturing and electricity. Mining and manufacturing, in particular, posted a second month of sequential growth. Production of consumer goods also rose after a few months of contraction.

The index of eight core infrastructure industries, which feeds into the index of industrial production, however, declined 1.5% in November from a year ago -- the fourth straight month of contraction. That was on account of shrinking production of electricity, steel, coal, natural gas and crude oil. Both the core sector and industrial output numbers are reported with a one-month lag.

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.
