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.

The Covid-19 pandemic has made an unprecedented impact on the Indian businesses, particularly small and medium enterprises (SMEs) and startups. According to a joint survey by FICCI and Indian Angel Network (IAN), the pandemic has hit the businesses of around 70% startups.

With uncertainty in the business environment and an unexpected shift in priorities of the government as well as corporates, many startups are struggling to survive, it says.

In a nationwide survey on the 'Impact of Covid-19 on Indian Startups' involving 250 startups, 70% participants said their businesses had been impacted by Covid-19 and around 12% had shut operations.

The survey shows only 22% startups have cash reserves to meet the fixed cost expenses over the next 3-6 months, and 68% are reducing operational and administrative expenses.

Around 30% of the companies said they would retrench employees if the lockdown was extended too long. The 43% startups have already started 20-40% salary cuts over April-June.

Over 33% startups said investors had put the investment decision on hold and 10% said the deals had been scrapped. Only 8% startups had received funds as per the deals signed before Covid-19 outbreak, the survey revealed.

The reduced funding has forced startups to put a hold on business development and manufacturing activities, which has resulted in loss of projected orders.

The survey highlights the need of an urgent relief package for startups, including possible purchase orders from the government, tax relief and swifter tax refunds, and immediate fiscal support measures, including grants, soft loans and payroll grants.

Besides 250 startups, 61 incubators and investors also participated in the survey.

While 96% of investors accepted that their investments in startups had been impacted by Covid-19, 92% said their investments in startups would continue to be low over the next six months.

Around 59% investors said they would prefer to work with the existing portfolio firms in the coming months. Only 41% said they would consider new deals.

"A comparison of priority investment sectors before and during Covid-19 shows 35% investors are now looking at investments in healthcare startups, followed by EdTech, AI/Deep Tech, FinTech and Agri," said the survey.

Around 44% incubators surveyed said their day-to-day operations had been considerably hit by Covid-19. Most incubators are now supporting their portfolio firms by providing them virtual platforms to interact with mentors, investors and industries.

Dilip Chenoy, FICCI Secretary General, said, "The startup sector is stressed for survival at the moment. The investment sentiment is also subdued and is expected to remain so in the coming months. Lack of working capital and cash flows may lead to major layoffs over the next 3-6 months."

Indian startups needed an enabling ecosystem and flow of funds to continue operations, the survey said.

Padmaja Ruparel, President, Indian Angel Network & Co-Chair of FICCI Startup Committee, said, "In these uncertain times, as investors, we must play an important role to provide the Indian startups funding, mentoring and hand-holding support to stay afloat and come out at the other end of this crisis."

To that end, IAN recently announced a debt fund to help IAN portfolio companies raise working capital and ensure business continuity by partnering with debt providers.

This must be replicated on a wider scale, so a larger number of startups are provided the capital support to make it during these tough times, Ruparel said.

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.
