[vc_row][vc_column][vc_column_text]A team of Indian astronomers have identified an extremely large supercluster of galaxies and have named it Saraswati.

This previously unknown, extremely large supercluster of galaxies, was discovered by a team of astronomers from the Inter University Centre for Astronomy & Astrophysics (IUCAA), and Indian Institute of Science Education and Research (IISER), both in Pune, India, and members of two other Indian universities. The team was led by Joydeep Bagchi from IUCAA, while others included Shishir Sankhyayan, a PhD student at IISER, Pratik Dabhade, an IUCAA research fellow, Joe Jacob of the Newman College, Kerala, and Prakash Sarkar of the National Institute of Technology, Jamshedpur.

The discovery comes close on the heels of another, reported on July 1, of “a large sample of giant radio galaxies” by the same institution. A six-member team of Indian astronomers led by Pratik Dabhade from IUCAA had reported the discovery of 25 extremely rare kind of galaxies called giant radio galaxies (GRGs), known to be the largest known galaxies in the universe. Bagchi was also part of the team.

Saraswati supercluster, located in the direction of constellation Pisces, is one of the largest known structures in the nearby Universe, and is at a distance of 4,000 million (400 crore) light-years away from us. Our own galaxy is part of a Supercluster called the Laniakea Supercluster, announced in 2014 by Brent Tully at the University of Hawaii and collaborators.

Superclusters are the largest coherent structures in the Cosmic Web. A Supercluster is a chain of galaxies and galaxy clusters, bound by gravity, often stretching to several hundred times the size of clusters of galaxies, consisting of tens of thousands of galaxies. The newly discovered ‘Saraswati’ supercluster, for instance, extends over a scale of 600 million light-years and may contain the mass equivalent of over 20 million billion suns. \

The Saraswati supercluster has a total of 43 clusters of galaxies. The typical size of a galaxy here is around 250,000 light years.

Two most massive clusters of galaxies in the Saraswati supercluster : “ABELL 2631” cluster (left) and “ZwCl 2341.1+0000” cluster (right). “ABELL 2631” resides in the core of the Saraswatisupercluster. The Saraswati supercluster has a total of 43 clusters of galaxies.

In a press statement, Joydeep Bagchi from IUCAA, the lead author of the paper and co-author Shishir Sankhyayan (PhD scholar at IISER, Pune) said, “We were very surprised to spot this giant wall-like supercluster of galaxies, visible in a large spectroscopic survey of distant galaxies, known as the Sloan Digital Sky Survey (see figure above). This supercluster is clearly embedded in a large network of cosmic filaments traced by clusters and large voids.”

Previously only a few comparatively large superclusters have been reported, for example the ‘Shapley Concentration’ or the ‘Sloan Great Wall’ in the nearby universe, while the ‘Saraswati’ supercluster is far more distant one. “Our work will help to shed light on the perplexing question; how such extreme large scale, prominent matter-density enhancements had formed billions of years in the past when the mysterious Dark Energy had just started to dominate structure formation,” said Bagchi.

“Saraswati” (or “Sarasvati”), a word that has proto-Indo-European roots, is a name found in ancient Indian texts to refer to the major river around which the people of the ancient Indian civilization lived. It is also the name of the celestial goddess who is the keeper of the celestial rivers. In modern India, Saraswati is worshipped as the goddess of knowledge, music, art, wisdom and nature – the muse of all creativity.

Their finding will be published in the latest issue of The Astrophysical Journal, one of the premier research journals of the American Astronomical Society.[/vc_column_text][/vc_column][/vc_row]

Rahul Gandhi is right, Gautam Adani should be arrested: RJD president Lalu Yadav

“Rahul Gandhi is right. Adani should be arrested,” said Prasad, who is an old ally of the Congress and a staunch opponent of the BJP, to which Adani is said to be close.

RJD president Lalu Prasad Yadav on Friday spoke in support of Congress leader Rahul Gandhi’s demand for immediate arrest of Gautam Adani, after the Industrialist was charged in the US for alleged bribery and fraud.

Gandhi, the Leader of Opposition in the Lok Sabha, said on Thursday that Gautam Adani should be arrested immediately, and his protector Madhabi Puri Buch should be investigated

The former Congress chief claimed that the recent developments vindicate his long-standing allegations against Gautam Adani. He took a sharp dig at Prime Minister Narendra Modi and alleged that Modi is protecting Adani, and is also involved in corruption. 

Yadav, the former chief minister of Bihar, was responding to queries from journalists here about Gandhi’s statement on the previous day, in the backdrop of charges of bribery and fraud against the Adani group in the US.

“Rahul Gandhi is right. Adani should be arrested,” said Prasad, who is an old ally of the Congress and a staunch opponent of the BJP, to which Adani is said to be close.

The RJD supremo, who incidentally has been convicted in several fodder scam cases and is on bail, was also asked about prospects of the INDIA bloc, of which his party is a part, in Jharkhand, where the counting of votes for assembly polls is scheduled on Saturday.

Speaking to PTI, the ailing septuagenarian replied, “I would like to remain focused on my statement that Adani must be arrested. I am not worried much about a new government (in Jharkhand) where we are already in power.” Jharkhand witnessed a straight battle between the INDIA bloc and the BJP-led NDA, which included the JD(U) headed by Nitish Kumar, Prasad’s arch-rival and the current Chief Minister of Bihar.

Addressing a press conference on Thursday, Gandhi further said that Chief Ministers have been jailed for scams of Rs 10-15 crore, but Adani, who has committed a scam of Rs 2000 crore is walking free.

Cash for votes row: BJP leader Vinod Tawde sends legal notice to Rahul Gandhi, Mallikarjun Kharge, asks them to apologise or face defamation

BJP leader Vinod Tawde, accused of distributing cash to influence voters, has sent a legal notice to Congress leaders Mallikarjun Kharge, Supriya Shrinate and Rahul Gandhi over the controversy. The BJP leader has demanded their apologies or face a Rs 100-crore defamation case.

Vinod Tawde’s legal notice came after regional party Bahujan Vikas Aghadi (BVA) leader Hitendra Thakur on Tuesday accused him of distributing Rs 5 crore at a hotel in Virar in Palghar district, 60 km from Mumbai, to woo voters.

In the legal notice, the BJP leader said the allegations against him were false, baseless and made with malafide intentions. He claimed that he demanded an apology from the three Congress leaders for their remarks against him in the cash-for-votes row or he would be forced to initiate criminal proceedings against them.

Just a few hours before the Assembly Elections, a video went viral on Tuesday showing BVA workers storming into the hotel in Palghar during a meeting between Vinod Tawde and Rajan Naik, the BJP candidate from the Nalasopara seat. The BVA workers alleged that Tawde was caught red-handed with Rs 5 crore cash.

In the viral video, the BVA workers were seen taking out bundles of cash from a bag, while Tawde was sitting at a distance. The BVA workers also took pictures and videos of him on their phones. Amid these allegations, BVA leaders said that Rs 5 crore cash was distributed, an election official on Tuesday said Rs 9.93 lakh cash was recovered from the hotel rooms.

However, Vinod Tawde denied the allegation, saying he was only providing guidance to party workers on poll procedures and said he was not stupid enough to distribute money at his opponent’s hotel. Speaking to the media, he said that the Vivanta Hotel is owned by the Thakurs, and he is not stupid to go to their hotel and distribute money there.

The Police registered two FIRs against Tawde, BJP candidate Naik and others in connection with the controversy. Additionally, the Election Commission filed three FIRs against Tawde.
