Upgraded GMRT measures the mass of hydrogen in distant galaxies

A team of astronomers from the National Centre for Radio Astrophysics Pune, and the Raman Research Institute (RRI), Bengaluru, has used the upgraded GMRT to measure the atomic hydrogen content of galaxies 8 billion years ago. This is the earliest epoch in the universe for which there is a measurement of the atomic gas content of galaxies. This research has been published in the 14 October 2020 issue of the journal Nature.

Nano-Silica for RNA Extraction from Viruses

RNA extraction is the first step to perform a coronavirus test. Researchers at Tata Institute of Fundamental Research (TIFR), Mumbai, studied dendritic fibrous nanosilica (DFNS) for RNA extraction from cells. It was shown that RNA from the cells could be extracted by DFNS with higher or equivalent efficiency than commercially available silica. This study has the potential to initiate the development and commercialization of indigenous DFNS based [...]

Cosmic X-rays reveal an indubitable signature of black holes

A black hole is an exotic cosmic object, from within which nothing, not even light, can escape. Definitive proof of the existence of such objects is a holy grail of physics and astronomy. An international team of astrophysicists, consisting of Mr. Srimanta Banerjee, Professor Marat Gilfanov, Professor Sudip Bhattacharyya and Professor Rashid Sunyaev, has found by far the strongest steady signature of stellar-mass black holes to date, from the [...]

Magnetic field with the edge!

This study overturns a dominant six-decade old notion that the giant magnetic field in a high intensity laser produced plasma evolves from the nanometre scale. Instead the field actually originates at macroscopic scales defined by the boundaries of the electron beam that is propagating in the plasma. This could alter our understanding of magnetic fields in astrophysics and laser fusion and may help in designing next generation high energy [...]

Microscopic deformation of a neutron star inferred from a distance of 4500 light-years

Gravitational waves, which are ripples in spacetime, have recently provided a new window to the universe. But continuous gravitational waves, for example from a slightly deformed and spinning neutron star, a star which is incredibly dense, have so far not been detected. A recent research work by Prof. Sudip Bhattacharyya has inferred continuous gravitational waves from a neutron star and has estimated the stellar microscopic deformation from a [...]
