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.

Mumbai, Jul 30: Counterfeiting incidents have increased 24 per cent in the country in 2019 over the previous year, creating an over Rs 1 lakh crore hole in the economy, according to a report.

The report also said counterfeiters are having a free run due to the pandemic-driven disruptions to organised supply chains and the resultant spike in consumer demand.

According to the report by ASPA, a self-regulated industry body of anti-counterfeiting and traceability solutions providers, counterfeiting has risen steadily in the last few years, and exploiting the pandemic as a cover for their activities.

Between February and April 2020, over 150 incidents of counterfeiting cases were reported, mostly about fake PPE kits, sanitisers and masks taking advantage of the high demand for these products, it noted.

"There was a 24 per cent increase in counterfeiting in 2019 over 2018, leading to the loss of more than Rs 1 lakh crore to the overall economy," said Nakul Pasricha, president of Authentication Solution Providers Association.

The association works with global authorities like the International Hologram Manufacturers Association, Counterfeit Intelligence Bureau of the Interpol, and domestic industry lobbies like Ficci, he said.

Counterfeiting is a universal issue and is 3.3 per cent of global trade, according to the OECD data, impacting social and economic development across the world.

The report lists the currency, FMCG, alcohol, pharma, documents, agriculture, infrastructure, automotive, tobacco, lifestyle and apparel, as the 10 sectors impacted most by counterfeiting.

Among these, currency, alcohol and FMCG continue to be the top three sectors with the highest counterfeiting in the last two years. The FMCG sector is most vulnerable, as counterfeit incidents rose 63 per cent between 2018 (79) and 2019 when the reported cases jumped to 129.

Within the states, the fakers have a free run in Uttar Pradesh, Bihar, Rajasthan, Madhya Pradesh, Bengal, Punjab, Jharkhand, Delhi, Gujarat, and Uttarakhand, calling for urgent actions to frame anti-counterfeiting policy measures.

According to the report, UP continues to be on top followed by Bihar, Rajasthan, and together these three states represent almost 45 per cent of all counterfeiting reported in the last two years.

What is more alarming is that counterfeiting is not limited to high-end luxury items today, as common everyday items as fake cumin seeds, mustard cooking oil, ghee, hair oils, soaps, baby care vaccines and medicines are aplenty in the markets.

"There is an urgent need for building and nurturing authentication ecosystems in the country with the active involvement and active participation of all stakeholders," said Pasricha.

New Delhi, June 27: The Prime Minister Narendra Modi-led union government of India is not ready to stop all imports from aggressive China in spite of mount calls to boycott Chinese products in India.

The Centre is reportedly considering to stop only non-essential imports from the neighbouring country.

However, the Inward shipment in sectors such as automobiles, pharmaceuticals, certain electronics and others will continue until a domestic alternative is found.

“India will gradually move towards import substitution. It will not happen overnight. In the meantime, attention has to be paid on production and job creation. We cannot throttle our industry. There are certain absolutely essential imports. Needless to say, those will keep going,” official sources said.

Sources said that both the government and the industry are in the process of identifying products that can be domestically manufactured in the medium term. There are certain chemicals, automotive components, handicrafts, cosmetics, agriculture items and certain consumer electronics, which can be manufactured domestically in the short to medium term. The government is doing all it can to raise the capacity of domestic industries.

However, there are certain other imports in the automobile and the pharmaceutical sectors which cannot be done away within the short to medium term. Their domestic production at the moment may not be that cost-effective.

The six-crore strong traders’ body CAIT has been at the forefront of such a demand and has launched a campaign to celebrate Indian Diwali this year with a total absence of Chinese goods.

“Ease of doing business, capital availability at lower rates and globally competitive logistics and energy costs are some of the prerequisites that the government should look into to ensure the growth of the domestic auto component industry,” according to Automotive Component Manufacturers Association of India (ACMA) Director General Vinnie Mehta.

Maruti Suzuki Chairman R C Bhargava said, “People who are boycotting Chinese goods have to remember that in some cases it may lead to their being asked to pay more for the same product."

Meanwhile, domestic rating agency Acuite Ratings & Research has analysed the current import portfolio from China and found 40 sub-sectors have the potential to lower their import dependency on China. These sectors contribute to $33.6 billion worth of imports from China and about 25% of these imports can be substituted by local manufacturing without any significant additional investments.

Srinagar, Jun 30: On the deadly attack at Karachi Stock Exchange on Monday morning, a Kashmiri social activist and journalist warned that the incident is a stark reminder to all those in Pakistan supporting Jihad and attacked Pakistan prime minister Imran Khan for ignoring development agenda in Balochistan.

Yana Mir, the editor-in-chief of The Real Kashmir News, said, "Karachi Stock Exchange attack is a reminder to all those in Pakistan supporting Jihad. Remember @imrankhan that Youth is restless and they want development agenda. These young boys of BLA are also looking for a life which is settled and peaceful. Wake up Imran Khan and you Kashmiris also. Pakistan is going to finish you. Open your eyes."
Four heavily armed terrorists attacked the busy Pakistan Stock Exchange building in Karachi with grenades today, killing four security guards and a police officer before being shot dead in an exchange of fire, authorities said.

The terrorists, who arrived in a car, stormed the Karachi Stock Exchange building by firing indiscriminately and lobbed grenades at the main gate of the multi-storey building situated in the city's high-security commercial hub.

Balochistan is a well-known region rich in natural resources but the Balochis have always been deprived of basic facilities. No hospitals are available in Balochistan. If there are some then medical facilities and equipment are not available in hospitals. The education system is pathetic and similar is the case with the infrastructure: the roads, water system, agriculture and almost all fields of life.

It is pertinent to mention that enforced disappearances and abductions by the Pakistani military establishment have also been carried out regularly and for innumerable times in Balochistan. Leaders, activists, and vocal members of various student organizations have been detained by the security forces and kept in confinement. While others have been shot dead.

This crime against humanity has been going on for so long and so systematically in Balochistan that it has come to be considered as a normal state of affairs in the province. Many social and human rights activists have flagged the issue of oppression by the Pakistani establishment before the United Nations and other international agencies.

According to the Commission of Inquiry on Enforced Disappearances, an entity established by the Pakistani government, about 5,000 cases of enforced disappearances have been registered since 2014. Most of them are still unresolved.

Independent local and international human rights organisations put the numbers much higher. Around 20,000 have reportedly been abducted only from Balochistan, out of which more than 2,500 have turned up dead as bullet-riddled dead bodies, bearing signs of extreme torture.

Before being elected as Prime Minister, Imran Khan had admitted in multiple interviews about the involvement of Pakistan's intelligence agencies in enforced disappearances as well as extrajudicial killings and vowed to resign if he was unable to put an end to the practice, holding those involved responsible. But times have passed and only reports are available to narrate the true story.
