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.

New Delhi, Jan 28: Stepping up attack on Chief Minister Arvind Kejriwal, Union Home Minister Amit Shah on Monday dared the AAP chief to visit the anti-CAA protest site at Shaheen Bagh so that the people of Delhi can decide whom to vote for in the assembly election.

Addressing a rally in Rithala in northwest Delhi, Shah said Kejriwal and Congress leader Rahul Gandhi were against the construction of Ram temple, the scrapping of provisions of Article 370 and not bothered about the country's image and soldiers.

The opposition fears that they will upset their vote bank, he said and asked, "Are you their vote bank? Where is their vote bank?" To this, the crowd replied, "Shaheen Bagh".

The BJP leader claimed that the Delhi Police has booked Sharjeel Imam, a JNU student, on the charge of sedition for his comment of "trying to cut chicken's neck" and breaking the North East from the rest of the country.

"I want to ask Kejriwal whether he is in favour of apprehending Sharjeel Imam or not? Whether you are with the people of Shaheen Bagh or not, please tell the people of Delhi," Shah said.

Imam was one of the initial organisers of the Shaheen Bagh protest.

Hitting back at the BJP, Kejriwal alleged that the saffron party does not want to open the Shaheen Bagh stretch of the Kalindi Kunj road as it is doing "dirty politics" over it.

He said law and order in the national capital lies entirely with the Centre and "if they are saying that they need permission from me, I am giving them permission, open the road in one hour".

"I can give it to you in writing, the BJP does not want to open the route in Shaheen Bagh. The Shaheen Bagh route will remain closed till February 8 (election day) and it will open February 9," Kejriwal told reporters.

Calling Kejriwal a member of the 'tukde tukde' gang, a term used by the BJP to attack groups it accuses of working to promote violent leftists and separatism, Shah sought to return fire and said the protesters of Shaheen Bagh will not listen to his party.

"They will not listen to us. You people (AAP leaders) say that you are with Shaheen Bagh, if you have the guts then go and sit with them and let Delhi decide," Shah said.

At another election rally in Janakpuri, Shah accused Gandhi and Kejriwal of doing politics of "vote bank" on national issues and "supporting" the protest at Shaheen Bagh while instigating riots and vandalism.

"The Modi government will not spare anti-national elements," he warned.

Upon mentioning the recent Supreme Court judgment on Ayodhya, Shah was greeted with cheers and chants of 'Jai Shri Ram'.

The home minister further said that this was the first Republic Day in Jammu and Kashmir after the abrogation of Article 370 and the tricolour was unfurled there with enthusiasm and without any bloodshed.

The former BJP president also attacked the Kejriwal government for not fulfilling promises like regularising temporary employees, providing free wifi, opening new schools and colleges, constructing roads and cleaning the Yamuna.

"Kejriwal government is in power since five years but till today there is no clean drinking water in the city. There are no good schools or hospitals as claimed by him. When I visited a Delhi government school, I saw that it was operating from a building that was illegally built and falls in the list of those that to be erased," Shah said.

He claimed that Kejriwal came to power with the help of Anna Hazare's anti-corruption movement but "completely changed" later on.

"He had said that he would not take any government accommodation or vehicles and other facilities but after becoming chief minister he availed all these facilities," Shah said.

He also slammed the Delhi government for not sanctioning the prosecution of former JNU students' union leader Kanhaiya Kumar in a sedition case.

Shah said if the national capital comes under the leadership of Modi, it will become the best city in the world.

The BJP has a vision for development of Delhi and cleaning the Yamuna river will be on top of our agenda, he said.

"Yamuna river is still dirty as against his (Kejriwal) claims of cleaning the river... Modi and Yogi (Adityanath) have cleaned Ganga river as promised. We will make Yamuna Riverfront like Sabarmati riverfront in Ahmedabad," Shah said.

However, a sizeable majority of those present at the public meeting was not convinced by the claims and promises made by Shah.

Bablu Yadav, a migrant and resident of Janakpuri said, "Shah and Modi can only talk but Kejriwal knows how to perform. They keep raking up issues like Ayodhya, Kashmir, Muslims and Pakistan... what are they waiting for if they want to attack Pakistan? They are in power, so why don't they destroy it instead of telling us how wrong Pakistan is?"

Another local Deepak Shrivastava who attended the Janakpuri meeting said, "All we hear from Modi and Shah are pep talks. I am an engineer from BHU and searching for a job. This government has failed the country's youth."

"Now, they have a problem with protests in universities but it is the same youth who brought them to power in 2014. The same youth will ensure their defeat," he added.

The public meeting in Janakpuri witnessed two incidents of pick-pocketing as the thieves managed to steal Rs 37,500 in cash and a mobile phone, police said.

New Delhi, Mar 15: Dozens of Hindu activists held a cow urine party in New Delhi on Saturday to protect themselves from the new coronavirus, as countries around the world struggle to control the deadly pandemic.

Members and supporters of the All India Hindu Mahasabha staged fire rituals and drank from earthen cups to fight the Covid-19 virus at the gathering in New Delhi dubbed a "gaumutra (cow urine) party".

"Whoever drinks cow urine will be cured and protected," Hari Shankar Kumar, a volunteer at the event, said as he served the remedy in brown clay cups.

Governments and scientists have said no medicine or vaccine is available to protect or cure people of the infection that has killed more than 5,400 people and infected nearly 150,000 across six continents.

Two people have died in India while more than 80 have fallen ill, and the government has ordered the closure of some land routes into the country and cancelled all visas to stop the spread of the virus in the world's second most populous country.

Members draped in saffron clothes chanted Hindu hymns at the fire ritual as devotees sang paeans for the sacred animal.

"We have gathered here and prayed for world peace and we will make an offering to the corona (virus) to calm it," Chakrapani Maharaj, the group's leader, told reporters before gulping down a cup of urine.

He then offered a glass to a devil-shaped caricature of the virus to "pacify" it.

He urged people to adopt the "tried and tested" practice of drinking cow urine to ward off diseases, and desist from killing animals and eating meat.

"The coronavirus is also a bacteria and cow urine is effective against all forms of bacteria that harm us," claimed Om Prakash, a participant from the neighbouring state of Uttar Pradesh.

One legislator from the BJP last week suggested use of the urine as well as cow dung can cure the coronavirus.

If your faith is scientific, simply go to Corona infected patients and cure it.

 

If you are successful, Not only India the whole world will be Hindus. 

 

If you cant, you will never do it with cow urine or any other urine. People will losse faith on your type of Hinduism.

Facebook will introduce a new notification screen on its platform that will warn users if the article they are about to share is over 90 days old, the company announced on Thursday.

“We’re starting to globally roll out a notification screen that will let people know when news articles they are about to share are more than 90 days old,” Facebook wrote in a blog post.

The social media platform had previously introduced a context button in 2018 that provides information about the sources of articles in the News Feed. Building upon that, the new feature will inform users about the timeliness of the article.

“To ensure people have the context they need to make informed decisions about what to share on Facebook, the notification screen will appear when people click the share button on articles older than 90 days, but will allow people to continue sharing if they decide an article is still relevant,” Facebook said.

The social media giant stated that timeliness is important in understanding the context of an article and curbing the spread of misinformation on the platform.

“News publishers, in particular, have expressed concerns about older stories being shared on social media as current news, which can misconstrue the state of current events. Some news publishers have already taken steps to address this on their own websites by prominently labelling older articles to prevent outdated news from being used in misleading ways,” Facebook added.

Apart from this, the platform will also be testing a similar notification screen for information related to the global Covid-19 pandemic. The notification screen will provide information about the source of the link shared in a post if the link is related to information on Covid-19. It will also direct people to its previously introduced Covid-19 information centre for “authoritative” health information, it said.
