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, Jun 23: In an unexpected development, the pump price of diesel is all set to surpass the petrol price in the capital, making it the most expensive transport fuel for the first time in a long time.

Globally, diesel is priced slightly above petrol prices due to the very nature of the product that has a higher cost of production. But in India, due to the lopsided taxation structure, diesel attracts lesser of the tax between the two auto fuels keeping its prices lower than petrol for last several years.

Diesel is currently priced at Rs 79.40 a litre in the Capital, just 36 paise short of petrol price that is being retailed at Rs 79.76 a litre. Going by the trend of price movement in the two products for the last few days where diesel prices have consistently increased by 50-60 paise per litre while the daily increase in petrol prices have fallen to just 20 paise on Tuesday, it is set to surpass petrol prices in next few days.

"Diesel price movement is sharper in international market and if oil companies follow the global price trend, diesel prices will surpass that of petrol later this week. It will be after many years that this would happen and is expected to sustain for some time unless government changes the tax structure of the petroleum products again," said an oil sector expert from one of the big four audit and advisory firms asking not to be named.

Interestingly, even in India the base price of diesel is expensive than petrol. According to the Indian Oil Corporation (IOC), while the base price of petrol in Delhi currently comes to Rs 22.11 per litre, the same for diesel is higher at Rs 22.93 per litre (effective from June 16, 2020). This has been the case for a long time, but retail price of petrol can be higher than diesel due to central and state taxes.

What has now brought diesel prices to a whisker of petrol prices in the capital is the Delhi government's decision early May to increase the Value Added Tax on diesel from 16.75 per cent to 30 per cent and on petrol from 27 per cent to 30 per cent. This increased the retail price of diesel and petrol in Delhi by Rs 7.10 and Rs 1.67 a litre respectively. With Central taxes on the two products already reaching identical levels, the Delhi governments move hastened price parity between petrol and diesel.

Currently, the Central excise on petrol is Rs 32.98 a litre while that on diesel it is Rs 31.83 a litre. The VAT on petrol in Delhi is Rs 17.71 a litre and that on diesel is Rs 17.60 a litre.

While the movement of retail pricing is being seen with a sigh of relief by vehicle owners whose cars run on petrol, those buying the relatively expensive diesel cars are now repenting on their decision. The development is also being seen with caution by automobile companies who have spent millions to ramp up their facilities for diesel run vehicles. The expectation is that demand for such cars will now fall, causing more damage to companies where sales are already impacted due to persistent economic slowdown and now the spread of COVID-19 pandemic.

"The pricing development would push automobile companies to strategies being followed by companies in the western markets where diesel run cars are not sold on fuel pricing differential, but on overall make and quality that puts them ahead of petrol run cars," the expert quoted earlier.

Yes, but for commercial vehicle sector the rising price of diesel had not been welcomed. In fact, the commercial transport sector had time an again threatened strike against the move to raise fuel prices.

With petrol and diesel retail prices closing, the case for adultering fuel has also gone down much to the relief of vehicle owners.

New Delhi, Jun 18: Reliance Industries Ltd on Thursday said it has sold a 2.32 per cent stake in its digital unit to Saudi Arabia's Public Investment Fund (PIF) for Rs 11,367 crore, taking the cumulative fund raising to about Rs 1.16 lakh crore in two months.

Starting with Facebook Inc on April 22, Reliance has sold almost 25 per cent of equity in Jio Platforms - the maximum reports suggest the company intends to dilute to financial investors.

The investment by Saudi sovereign wealth fund is "at an equity value of Rs 4.91 lakh crore and an enterprise value of Rs 5.16 lakh crore", the company said in a statement.

With this investment, Jio Platforms has raised Rs 115,693.95 crore from some of the leading global investment powerhouses at a time when the world is deeply impacted by the coronavirus pandemic, resulting in a recession kind of environment for the global economy.

"With the addition of PIF's investment, Jio Platforms has established partnerships with a marquee set of global financial investors, who will contribute to establishing the Digital Society vision for India," the statement said.

Jio Platforms houses India's biggest telecom firm by subscribers, Reliance Jio. With more than 388 million users, Jio has forced out several rivals and driven consolidation in the sector since entering the market in 2016 with free voice services and cut-price data.

Over the past two months, billionaire Mukesh Ambani's oil-to-telecom conglomerate has announced the sale of about $14 billion of assets, completed a Rs 53,124 crore rights issue and slowed the run rate of new investment by a quarter.

These will help Reliance meet its target of paying off Rs 1.61 lakh crore of net debt by the end of the year.
This is PIF's largest investment into the Indian economy to date.

Ambani, chairman and managing director of Reliance Industries, said, "We at Reliance have enjoyed a long and fruitful relationship with the Kingdom of Saudi Arabia for many decades. From oil economy, this relationship is now moving to strengthen India's New oil (data-driven) economy, as is evident from PIF's investment into Jio Platforms."

Yasir Al-Rumayyan, governor of PIF, commented: "We are delighted to be investing in an innovative business which is at the forefront of the transformation of the technology sector in India. We believe that the potential of the Indian digital economy is very exciting and that Jio Platforms provides us with an excellent opportunity to gain access to that growth."

"This investment will also enable us to generate significant long-term commercial returns for the benefit of Saudi Arabia's economy and our country's citizens, in line with our mandate to safeguard and grow the national wealth of the Kingdom," he said.

The transaction is subject to Indian regulatory and other customary approvals.

Morgan Stanley acted as financial advisor to Reliance Industries and AZB & Partners and Davis Polk & Wardwell acted as legal counsels.

Prior to this deal, Reliance had sold 22.38 per cent of Jio Platforms to investors including Facebook Inc, securing Rs 104,326.95 crore in eight weeks.

Facebook kicked off the party, investing Rs 43,573.62 crore for a 9.99 per cent stake on April 22. This was closely followed by a further Rs 60,753.33 crore in investment.

Silver Lake - the world's largest tech investor - bought a 1.15 per cent stake in Jio Platforms for Rs 5,665.75 crore on May 4. It invested another Rs 4,546.80 crore for additional 0.93 per cent stake on June 5, taking its total holding to 2.08 per cent
Private equity KKR and Vista Equity Partners have taken 2.32 per cent stake each for Rs 11,367 crore apiece. KKR invested in Jio Platforms on May 22 while Vista invested on May 8.

Abu Dhabi sovereign wealth fund Mubadala Investment Co picked up 1.85 per cent in Jio Platforms for Rs 9,093.60 crore on June 5. Abu Dhabi Investment Authority on June 7 invested Rs 5,683.50 crore for a 1.16 per cent stake in Jio Platforms.

On May 17, global equity firm General Atlantic picked up 1.34 per cent stake in Jio Platforms for Rs 6,598.38 crore.

Global investment firm TPG on June 13 picked up 0.93 per cent for Rs 4,546.80 crore while L Catterton bought 0.39 per cent for Rs 1,894.50 crore.

New Delhi, Jan 11: The Supreme Court is scheduled to hear the curative petition of two death row convicts in 2012 Nirbhaya gang-rape case on January 14.

A five-judge Bench of Justices N V Ramana, Arun Mishra, R F Nariman, R Banumathi and Ashok Bhushan will hear the petition filed by Vinay Sharma and Mukesh.

The duo had moved a curative petition in the top court after a Delhi court issued a death warrant in their name and announced January 22 as the date of their execution.

Besides them, two other convicts named Pawan and Akshay are also slated to be executed on the same day at 7 am in Delhi's Tihar Jail premises.

They were convicted and sentenced to death for raping a 23-year-old woman on a moving bus in the national capital on the night of December 16, 2012.

The victim, who was later given the name Nirbhaya, died at a hospital in Singapore where she had been airlifted for medical treatment.

A curative petition is the last judicial resort available for redressal of grievances. It is decided by the judges in-chamber.

If it is rejected, they are legally bound to move a mercy petition. It is filed before the President who has the power to commute it to life imprisonment.

The court after issuing a black warrant in their name gave them two weeks' time to file both the curative and mercy petition.
