Chennai, Jun 22: Commuting the death sentence to life imprisonment for five convicts, the Madras High Court on Monday set free Chinnasamy, the main convict, who had also been sentenced to death in the Udumalpet Shankar honour killing case.

A Division Bench comprising Justice M. Sathyanarayanan and Justice M. Nirmal Kumar also dismissed the appeal by the state police against the acquittal of three persons by a lower court.

The Bench ordered the five convicts sentenced for life to undergo a jail term of not less than 25 years.

In 2016, V. Shankar, who had married C. Kausalya, was killed by a gang in Udumalpet in Tamil Nadu. The gang also injured Kausalya in the attack.

It was alleged the parents of Kausalya -- Chinnasamy, Annalakshmi -- were against the marriage.

P. Pandidurai, the uncle of Kausalya at the behest of Chinnasamy and Annalakshmi had hired a gang to kill Shankar.

The gang killed Shankar in broad daylight in a public place and Kausalya too got injured in the attack as she tried to save her husband.

The Principal District and Sessions Court in Tiruppur had convicted and sentenced to death six accused persons -- Chinnasamy, P. Jagadeesan, P. Selvakumar, M. Manikandan, M. Mathan alias Michael and P. Kalaithamilvaanan.

The court also sentenced two other accused, K. Dhanraj for life and Manikandan to a five year jail term, while acquitting Annalakshmi, Pandidurai and Prasanna.

The convicts had filed an appeal against their sentence in the Madras High Court while the police filed an appeal against the acquittal of three persons.

New Delhi, Mar 7: The Union government has issued a Global Invite for Expression of Interest for disinvestment in Bharat Petroleum Corporation Limited (BPCL) from prospective bidders with a minimum net worth of $10 billion as of Saturday.

The EoI submissions can be made till May 2, whereas investor queries will be entertained till April 4.

Another condition pertains to a maximum of four members are permitted in a consortium, and the lead member must hold 40 per cent in proportion. Other members of the consortium must have a minimum $1 billion net worth.

The EOI allows changes in the consortium within 45 days, though the lead member cannot be changed.

The GoI proposes to disinvest its entire shareholding in BPCL comprising 1,14,91,83,592 equity shares held through the Ministry of Petroleum and Natural Gas, which constitutes 52.98 per cent of BPCL's equity share capital, along with the transfer of management control to the strategic buyer (except BPCL's equity shareholding of 61.65 per cent in Numaligarh Refinery Limited (NRL) and management control thereon).

The shareholding of BPCL in NRL will be transferred to a Central Public Sector Enterprise operating in the oil and gas sector under the Ministry and accordingly is not a part of the proposed transaction.

Washington D.C., Feb 6: An international team of astronomers has found an unusual monster galaxy that existed about 12 billion years ago when the universe was only 1.8 billion years old.

The team of astronomers was led by scientists at the University of California, Riverside.

Dubbed XMM-2599, the galaxy formed stars at a high rate and then died. Why it suddenly stopped forming stars is unclear.

"Even before the universe was 2 billion years old, XMM-2599 had already formed a mass of more than 300 billion suns, making it an ultra massive galaxy," said Benjamin Forrest, a postdoctoral researcher in the UC Riverside Department of Physics and Astronomy and the study's lead author.

"More remarkably, we show that XMM-2599 formed most of its stars in a huge frenzy when the universe was less than 1 billion years old and then became inactive by the time the universe was only 1.8 billion years old," Forrest added.

The team used spectroscopic observations from the W. M. Keck Observatory's powerful Multi-Object Spectrograph for Infrared Exploration or MOSFIRE, to make detailed measurements of XMM-2599 and precisely quantify its distance.

The study results appear in the Astrophysical Journal.

"In this epoch, very few galaxies have stopped forming stars, and none are as massive as XMM-2599," said Gillian Wilson, a professor of physics and astronomy at UCR in whose lab Forrest works.

"The mere existence of ultramassive galaxies like XMM-2599 proves quite a challenge to numerical models. Even though such massive galaxies are incredibly rare at this epoch, the models do predict them."

"The predicted galaxies, however, are expected to be actively forming stars. What makes XMM-2599 so interesting, unusual, and surprising is that it is no longer forming stars, perhaps because it stopped getting fuel or its black hole began to turn on. Our results call for changes in how models turn off star formation in early galaxies," the professor stated.

The research team found XMM-2599 formed more than 1,000 solar masses a year in stars at its peak of activity -- an extremely high rate of star formation. In contrast, the Milky Way forms about one new star a year.

"XMM-2599 may be a descendant of a population of highly star-forming dusty galaxies in the very early universe that new infrared telescopes have recently discovered," said Danilo Marchesini, an associate professor of astronomy at Tufts University and a co-author on the study.

"We have caught XMM-2599 in its inactive phase," Wilson said, who led the W. M. Keck Observatory data acquisition
Co-author Michael Cooper, a professor of astronomy at UC Irvine, said this outcome is a strong possibility.

"Perhaps during the following 11.7 billion years of cosmic history, XMM-2599 will become the central member of one of the brightest and most massive clusters of galaxies in the local universe," he said.

"Alternatively, it could continue to exist in isolation. Or we could have a scenario that lies between these two outcomes," he stated.

The study was supported by grants from the National Science Foundation and NASA.
