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 [...]

Nano-Sponges of Solid Acid Transforms Carbon Dioxide to Fuel and Plastic Waste to Chemicals

The primary cause of climate change is atmospheric CO2, whose levels are rising every day. There is, therefore, a great need to find ways to reduce CO2 levels. On other hand, an excessive amount of plastic waste has become a serious environmental problem. In this work, researchers dealt with both these problems at one stroke, by developing nano solid acids which transform CO2 directly to fuel (dimethyl ether) and plastic waste to chemicals [...]

Sero-surveillance: Random Community Testing to Assess Prevalence of COVID-19 Infection in Mumbai

In a joint venture between Tata Institute of Fundamental Research (TIFR), Translational Health Science and Technology Institute (THSTI, Faridabad), University of Chicago, Duke University, ATE Chandra Foundation (Mumbai), Kasturba Hospital (Mumbai) and IDFC Institute (Mumbai), under the aegis of the NITI Aayog, a pilot project was launched on 29 June 2020 to understand the extent to which the population in Mumbai has already been exposed to [...]
