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.

New Delhi, Jun 25: Union Home Minister Amit Shah on Thursday hit out at Congress for "unceremoniously sacking" its spokesperson and said that leaders in the opposition party are "feeling suffocated".

To substantiate his point, Shah referred to the recent Congress Working Committee (CWC) meet in which senior members and younger members raised a few issues, however, they were "shut down".

Taking to Twitter, Shah posted two English dailies' articles titled -- "Not scared of PM Modi, but many in the party dodge him: Rahul at Congress Working Committee meet" and "Congress removes Sanjay Jha as party spokesperson after critical article".

Last week, Jha was dropped as AICC spokesperson and Abhishek Dutt and Sadhna Bharti appointed as National Media Panelist of Congress party.

"During the recent CWC meet, senior members and younger members raised a few issues. But, they were shouted down. A party spokesperson was unceremoniously sacked. The sad truth is - leaders are feeling suffocated in Congress," the Union Minister tweeted.

Meanwhile, Shah also targetted Congress on the completion of 45 years of emergency, which was imposed by former Prime Minister Indira Gandhi on June 25, 1975 and asked the party to self introspect.

"As one of India's opposition parties, Congress needs to ask itself: Why does the Emergency mindset remain? Why are leaders who do not belong to 1 dynasty unable to speak up? Why are leaders getting frustrated in Congress? Else, their disconnect with people will keep widening," he wrote.

Jha the spokesperson, tried to be under the payroll of BJP, so disciplinary action was imminent.

 

Discipline has no compromise.

Feb 4: Amid the agitations against Citizenship Amendment Act, National register of Citizens and National Population Registration across the country, Prime Minister Narendra Modi on Monday said that there is a "political design" behind all these protests including in Delhi's Jamia and Shaheen Bagh to ruin the harmony of the nation.

"Be it Seelampur, Jamia or Shaheen Bagh, protests held over the past several days regarding the Citizenship Amendment Bill. Is this just a coincidence? No. This is an experiment," said Prime Minister Narendra Modi in his first election rally for Delhi polls at Karkardooma.

"There is a political design behind all these protests including Jamia and Shaheen Bagh. These protests are a conspiracy to divide India. These protests are going to ruin the harmony of the nation," he asserted.

Lambasting the opposition parties including Congress and Aam Aadmi Party for supporting the ongoing protests, he said: "But AAP and Congress are provoking people. Constitution and tricolor are being kept in front and attention is being diverted from the real conspiracy."

"These people were doubting the ability of our forces during surgical strikes. Do citizens of Delhi want such people in power? These people are saving those who want to break India into pieces," he added.

People have been protesting at Jamia and Shaheen Bagh against CAA, NRC and NPR. Members of the Opposition have deemed CAA "discriminatory and anti-Constitution" while the Centre has maintained that the new law has no effect on Indian citizens.

Recently, two firing incidents took place near Jamia Millia Islamia University.On Sunday night, the firing incident was reported near gate number five at the university following which people including some students of the varsity gathered outside the Jamia Nagar police station. They returned from the Jamia Nagar police station after their complaint was registered.

Earlier, a student sustained injuries after a young man fired at the protestors near Jamia.

Once again incorrect statement and only to divert people attention.  Every one knows who is ruining image of our nation.   this govt has completely failed in all aspects and trying to survive by misguiding the citizens.  Economy is reaching zero and GDP is coming down day by day, Banks and industries on getting closed. youths are unemployed due to no chance.   However, Govt is giving false statement that nothing to worry and our economy if growing.   this govt has brought black bills of CAA and MPR only to divide the society and keep them engaged and forget the falling economy.   If this situation continues, our nation will be one of the poorest countries in the world.   This govt is trying to sell all Govt hold units like Railway, Insurance, etc to private companies only to help the industrialists and to get commission from them.    LIC was running in profit till 4 to 5 years back, but now its running in loss.   Huge amount of money from LIC is taken by Govt to hide the downfall of economy.   Only God can save our country from the hands of present looters + decoits.

Bidar, Jan 31: In a disturbing development, the police have arrested two women – a schoolteacher and mother of two students – in connection with staging a play against the Citizenship Amendment Act and National Register of Citizens at a prestigious school in Karnataka’s Bidar.

The arrested have been identified as Farida Begum, headmistress of Shaheen Urdu Medium Primary School, and Navida, the mother of a student who played a role in the play.

The development comes days after police filed a sedition case against the management of Shaheen School following a complaint lodged by the ABVP claiming that play contained objectionable dialogues against Prime Minister Narendra Modi. The drama was performed during an annual function of the school on January 21.

Bidar SP Sreedhara T confirmed the arrest of Farida Begum and Navida, and said the accused were remanded to judicial custody on Thursday.

Sreedhara said that based on the complaint by one Neelesh Rakshal, the police filed an FIR under sedition charges, initially against the headmistress and management of the school on Saturday. He said that the police have questioned about 50 people, including the members of the management committee of Shaheen Urdu Medium Primary School, staff of the school, audience, parents and students. Based on the statements and evidence, the headmistress and the parent have been arrested.

The SP said that as per the statements and evidence collected, they came to know that the headmistress played a major role in organising the controversial play. The students practised the drama for a week and the headmistress knew about its script containing controversial dialogues against the Prime Minister and senior BJP leaders.

Considering this, she has been booked for creating communal disharmony and abetting sections. The SP said that when a dialogue of slapping the Prime Minister was said on the stage, Navida gave her chappals to the child, to be used while saying the dialogue. She has been arrested for abetting.

Expressing shock over sedition case and arrests, Dr Abdul Qadeer, the chairman of Shaheen Group of Institutions, said that the school management would fight out legally.

About Shaheen Group

Founded by Dr Abdul Qadeer, Shaheen Group has spread its wings through nine states of India and runs 43 institutions and related units. It has also been running a unique course for Huffaz named as ‘Hifz Ul Quran Plus’ in which Huffaz are prepared to appear and excel in competitive exams (NEET-JEE(IIT)).
