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.

Jan 21: Indian policymakers may make it easier for companies to tap foreign funding, as a prolonged cash squeeze makes it tough for firms to borrow at home.

Investors are speculating about potential steps Finance Minister Nirmala Sitharaman could unveil when she presents the nation’s budget on Feb. 1. These measures may include freeing up firms to borrow at higher rates and offering tax breaks to global funds.

“The government will need to relax local rules to make it easier for Indian companies to raise debt overseas and tide over the funding crunch in the onshore market,” said Raj Kothari, London-based head of trading at Jay Capital Ltd. “At the same time, they need to ensure that the borrowers tapping offshore markets abide with stricter corporate governance so as to avoid further defaults.”

A prolonged crisis in India’s shadow bank sector and a pile of bad loans at traditional lenders is making it expensive for Indian companies, other than the best-rated firms, to access funding. The government has tried a series of measures to spur domestic credit, including providing so-called credit enhancement and allowing tiny firms to restructure debt.

Here are some steps Sitharaman may consider to spur foreign borrowing:

• She could raise the cap of 450 basis points above Libor, which limits overall foreign debt costs for Indian companies

• This could help lower-rated firms sell bonds abroad. Indian companies rated BBB currently borrow at more than 10%, about 3.8 percentage points more than their top-rated peers;

• Sitharaman could waive the withholding tax foreign investors need to pay on holdings of rupee-denominated debt sold by Indian companies abroad

• The waiver was offered between September 2018 to March 2019, but wasn’t extended as the highest global interest rates since the financial crisis deterred Indian borrowers. Since then, the three-month Libor has dropped by about 1 percentage point

• She could permit Indian property developers and housing finance lenders to sell overseas bonds for reasons beyond affordable housing projects

• New funding lines to the real estate sector, arguably ground zero of India’s economic slowdown, could help kickstart consumption and investment as the industry is the nation’s biggest job-creator.

Srinagar, Jan 15: The Jammu and Kashmir administration on Tuesday evening allowed mobile Internet in parts of Jammu region and broadband in establishments providing essential services, days after the Supreme Court ordered a review of the curbs imposed in the Union Territory.

The order comes into effect from January 15 and shall remain in force for seven days, a government communication said.

In a three-page order, the administration asked Internet service providers to offer broadband facility (with Mac binding) to all institutions dealing with essential services such as hospitals, banks and government offices.

In order to facilitate tourism, the broadband Internet services would be provided to hotels and tour and travel establishments, the order said.

Mac Binding essentially means to enforce a client machine to work from a particular Internet Protocol address.

"Prior to giving such facility, the service providers have been asked to install necessary firewalls and carry out white-listing of sites that would enable government websites and website dealing with essential services like e-banking," the order said.

However, all social media sites remain out of bounds. "There shall be complete restrictions on social media applications allowing peer-to-peer communication and virtual private network applications for the time being," the order said.

The institutions and government offices that are being provided Internet access shall be responsible to prevent misuse, according to the order.

It said the 2G mobile connectivity on post-paid mobiles for accessing white-listed websites including e-banking will be allowed in districts of Jammu, Samba, Kathua, Udhampur and Reasi -- all in the Jammu region.

The order said that the police has brought material relating to the terror modules operating in Jammu and Kashmir including handlers from across the border who are attempting to aid and incite people by transmission of fake news and targeted messages through use of Internet.

The relaxation came days after the Supreme Court said access to the Internet is a fundamental right under Article 19 of the Constitution.

The SC verdict had come on Friday on a batch of pleas challenging the curbs imposed in Jammu and Kashmir after the Centre's abrogation of provisions of Article 370 on August 5 last year.

The court had also asked the Jammu and Kashmir administration to review within a week all orders imposing curbs in the Union Territory.

It had asked the J-K administration to restore Internet services in institutions such as hospitals and educational places providing essential services.

The J-K administration's Tuesday communication said that in view of the Supreme Court directions, the situation has been reviewed and Internet has been opened whereever it was possible keeping in view the security consideration.

In Kashmir, 400 additional Internet kiosks will be established, besides the 900 terminals which are already operational in the Valley.

Dubai, Apr 26: The Central Bank of the UAE (CBUAE) has instructed financial institutions in the country to search and freeze all bank accounts of Indian billionaire BR Shetty and his family along with those of companies where he has a stake.

The apex bank has also blacklisted several firms associated with Shetty along with their entire senior management.

In an advisory issued last week, CBUAE cited decisions of the Federal Attorney General and asked financial institutions to search and freeze any bank accounts, deposits or investments in the name of Shetty or his family members.

Financial institutions have been directed to stop transfers from these accounts and deny access to deposit boxes.

Currently in India and facing a string of charges, Shetty is the founder of NMC Health.

The heathcare provider was placed into administration by a UK court recently following an application by the Abu Dhabi Commercial Bank (ADCB) which alone has an exposure of $981 million (Dh3.6 billion).

Overall, UAE banks have a combined exposure of more than Dh8bn to NMC which owes money to Oman-based banks and financial institutions as well.

Probing credit facilities
The Central Bank has sought information about credit facilites extended to the Shettys along with details of their safe deposit boxes and the financial transfers they have made till date.

A similar advisory has been issued for NMC Healthcare and NMC Holding, based on the decision of the Head of Plenary Fund Prosecution.

The Central Bank has also blacklisted several companies associated with Shetty. Key staff members of these firms have been similarly blacklisted.
