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 23: Pakistan's Prime Minister Imran Khan called on Wednesday for the United Nations to help mediate between nuclear armed India and Pakistan over the disputed territory of Kashmir.

"This is a potential flashpoint," Khan said during a media briefing at the annual meeting of the World Economic Forum in Davos, Switzerland, adding that it was time for the "international institutions ... specifically set up to stop this" to "come into action".

The Indian government in August revoked the constitutional autonomy of Indian-administered Kashmir, splitting the Muslim-majority region into two federal territories in a bid to integrate it fully with the rest of the country.

Kashmir is claimed in full by both India and Pakistan. The two countries have gone to war twice over it, and both rule parts of it. India's portion has been plagued by separatist violence since the late 1980s.

Khan said his biggest fear was how New Delhi would respond to ongoing protests in India over a citizenship law that many feel targets Muslims.

"We're not close to a conflict right now ... What if the protests get worse in India, and to distract attention from that, what if ..."

The prime minister said he had discussed the prospect of war between his country and India in a Tuesday meeting with US President Donald Trump. Trump later said he had offered to help mediate between the two countries.

Khan said Pakistan and the United States were closer in their approach to the Taliban armed rebellion in Afghanistan than they had been for many years. He said he had never seen a military solution to that conflict.

"Finally the position of the US is there should be negotiations and a peace plan."

In a separate on-stage conversation later on Wednesday, Khan said he had told Trump in their meeting that a war with Iran would be "a disaster for the world". Trump had not responded, Khan said.

Khan made some of his most straightforward comments when asked why Pakistan has been muted in defence of Uighurs in China.

China has been widely condemned for setting up complexes in remote Xinjiang province that Beijing describes as "vocational training centres" to stamp out ""extremism and give people new skills.

The United Nations says at least one million ethnic Uighurs and other Muslims have been detained.

When pressed on China's policies, Khan said Pakistan's relations with Beijing were too important for him to speak out publicly.

"China has helped us when we were at rock bottom. We are really grateful to the Chinese government, so we have decided that any issues we have had with China we will handle privately."

New Delhi, Feb 18: India emerged as the world's fifth-largest economy by overtaking the UK and France in 2019, says a report.

A US-based think tank World Population Review in its report said that India is developing into an open-market economy from its previous autarkic policies.

"India's economy is the fifth-largest in the world with a GDP of $2.94 trillion, overtaking the UK and France in 2019 to take the fifth spot," it said.

The size of the UK economy is $2.83 trillion and that of France is $2.71 trillion.

The report further said that in purchasing power parity (PPP) terms, India's GDP (PPP) is $10.51 trillion, exceeding that of Japan and Germany. Due to India's high population, India's GDP per capita is $2,170 (for comparison, the US is $62,794).

India's real GDP growth, however, it said is expected to weaken for the third straight year from 7.5 per cent to 5 per cent.

The report observed that India's economic liberalisation began in the early 1990s and included industrial deregulation, reduced control on foreign trade and investment, and privatisation of state-owned enterprises.

"These measures have helped India accelerate economic growth," it said.

India's service sector is the fast-growing sector in the world accounting for 60 per cent of the economy and 28 per of employment, the report said, adding that manufacturing and agriculture are two other significant sectors of the economy.

The US-based World Population Review is an independent organisation without any political affiliations.

Feb 6: India has been ranked 40th out of 53 countries on a global intellectual property index, even as the country has shown improvement in terms of scores when it comes to the protection of IP and copyright issues, a top American industry body said on Wednesday.

India was placed at 36th position among 50 countries in 2019.

India's score, however, increased from 36.04 per cent (16.22 out of 45) in 2019 to 38.46 per cent (19.23 out of 50) in 2020, a 2.42 per cent jump in an absolute score.

However, India's relative score increased by 6.71 per cent, according to the International IP Index released by Global Innovation Policy Center or GIPC of the US Chambers of Commerce.

This year, it finds itself on the 40th place among 53 countries. Two new Index economies (Greece and the Dominican Republic) scored ahead of India. The Philippines, and Ukraine leapfrogged India.

"Since the release of the 2016 National IPR Policy, the government of India has made a focused effort to support investments in innovation and creativity through increasingly robust IP protection and enforcement," the GIPC said.

Since 2016, India has improved the speed of processing for patent and trademark applications, increased awareness of IP rights among Indian innovators and creators, and facilitated the registration and enforcement of those rights, it added.

According to the eighth edition of the annual report, India's score on the Chamber's International IP Index demonstrates the country's growing investment in IP-driven innovation and creativity. The Index specifically highlights a number of reforms over the last year that strengthen India's overall IP ecosystem, it said.

"In 2019, the Delhi High Court used dynamic injunctions to disable access to copyright-infringing content online, resulting in an increase in India's score on two of the copyright-related indicators," it said.

"The use of these injunctions places India alongside global leaders in copyright enforcement, including Singapore and the UK. As a result, India scores ahead of 24 other economies in the copyright indicators," the report said.

The Delhi High Court also issued a series of judgements that provide clarity on existing statutes related to trademark protection online, resulting in a score increase on one of the trademark-related indicators, it added.

The courts issued two precedential rulings that raised the bar for the damages awarded in IP-infringement cases and may provide a deterrent for future infringement. This resulted in an increase in score on one of the trademark-related indicators, it said.

Global Innovation Policy Center or GIPC said India also continues to score well in the Systemic Efficiency indicator, scoring ahead of 28 other economies in these indicators.

"This is a result of a concerted effort by the Indian government to consult with stakeholders during IP policy formation and create greater awareness about the importance of IP protection,” it said adding that India also remains a leader in the use of targeted incentives and IP assets for small and medium-sized enterprises (SMEs).

“To continue this upward trajectory, much work remains to be done to introduce transformative changes to India’s overall IP framework and take serious steps to consistently implement strong IP standards," the report said.

GIPC has identified several challenges for India. Prominent among them being patentability requirements, patent enforcement, compulsory licensing, patent opposition, regulatory data protection, transparency in reporting seizures by customs, and Singapore Treaty of Law of TMs and Patent Law Treaty.

"We are encouraged that Indian policymakers seem to recognize this Index as a valuable resource in their efforts to strengthen the country’s promising innovation ecosystem and enhance its competitiveness in an increasingly knowledge-based global economy,” the report said.

Observing that no other economy stands to gain more from strong Indian IP than India itself, the report said for example, no industry has been hurt more by copyright violations in India than the country’s own Bollywood industry, which loses almost USD3 billion to piracy each year.

"The number one way the Modi administration can demonstrate its commitment to the success of the Atal Innovation Mission, Accelerating Growth for New India’s Innovations, Make in India, Digital India, and Startup India is to strengthen its IP framework in ways that promote the legal and regulatory certainty necessary for greater R&D investment, high-value jobs, and greater innovative and creative outputs,” it said.

"Strong IP standards can further solidify India's position as the world’s fastest-growing economy, bolstering its reputation as a destination for doing business, foreign businesses’ ability to invest and make in India, thereby supporting the growth of India’s own innovative and creative industries," the report said.
