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.

People lost trust in Judiciary because of such horrible criminals.

 

He betrayed the whole nation. Unless he is booked, the judiciary will not restore the lost faith. 

 

 

The loss may be momentary in nature, It is the promise of the Almighty, He will ensure the justice is served to everyone.

New Delhi, Feb 10: The government is set to privatise Central Electronics Ltd, a CPSE under the Department of Science and Technology, by selling its 100% stake with management control and has invited the Expression of Interest for the same by March 16.

The selected bidder will be required to lock in its shares for a period of three years during which it cannot undertake the sale of its stake in CEL, the PIM (Preliminary Information Memorandum) said.

"The government of India has 'in-principle' decided to disinvest 100 per cent of its equity shareholding in CEL (which is equivalent to 100 per cent of the total paid up equity share capital of CEL) through Strategic Disinvestment with transfer of management control (Strategic Disinvestment or Transaction)," DIPAM, the Disinvestment Department, said.

The process for the transaction has been divided into two stages, namely, Stage I and Stage II.

After BPCL and Air India, this is yet another CPSE which government is slated to privatise if it gets offers from bidders.

The government has set a challenging target of Rs 2.1 lakh crore disinvestment proceeds from CPSE sell-offs and IPOs, OFSs (Offer for sale) in the next fiscal and it going out all guns blazing to meet that target after revising this fiscal target of Rs 1.05 lakh crore to Rs 65,000 crore.

The Interested Bidders (which can also include employees of CEL) must have a minimum net worth of Rs 50 crore as on March 2019. DIPAM has released complete invitation Preliminary Information Memorandum (PIM) of CEL. Resurgent India Limited is the advisor to the Transaction.

CEL is a pioneer in the country in the field of Solar Photovoltaic (SPV) with the distinction of having developed India's first Solar cell in 1977 and first Solar panel in 1978 as well as commissioning India's first solar plant in 1992.

More recently, it has developed and manufactured the first crystalline flexible solar panel especially for use on the passenger train roofs in 2015.

Its solar products have been qualified to International Standards IEC 61215/61730. CEL is further working on development of a range of new and upgraded products for signaling and telecommunication in the railway sector.

In the SWOT analysis of the CPSE, DIPAM has stated under weakness that "the company has weak financial loss due to past losses, high manufacturing cost and non payment of dues by state nodal agencies affecting the financial position of the company".

The CPSE has adequate land for expansion, the SWOT analysis said adding "the CPSE faces threat of dumping of solar cells at very low rates which makes solar PV manufacturing industry unviable".

Entry of new players in the market for solar products and railway signalling systems also is cited as a threat.
