A team of researchers at the Tata Institute of Fundamental Research, Mumbai and the Indian Institute of Technology, Kanpur have used extremely strong magnetic pulses to line up spins in a magnetic film on a scale never achieved before. They demonstrate beautiful concentric circular patterns of spins as large as hundreds of micrometers. The natural scale for such patterns is typically sub-micrometre. Creation of such large scale ordered spin [...]
Dr. Dharam Vir Lal, a scientist working at the National Centre for Radio Astrophysics of the Tata Institute of Fundamental Research (NCRA-TIFR), Pune, India has discovered a remnant radio galaxy at the peripheral region of a cluster of galaxies named Abell2065, using the upgraded Giant Metrewave Radio Telescope (uGMRT) and the Chandra X-ray Observatory. The research has been published in the 16 July 2021 issue of the Astrophysical Journal.
Great leaps in science and technology have been propelled by recent advances in seeing fast evolving physical phenomena, as they happen. Femtosecond lasers from the infrared to the X-ray region have enabled us to ‘watch’, in real time, atoms dance in molecules and solids on femtosecond and picosecond timescales. Watching such fascinating motions not just in real time but at the spatial locations where they happen, is a bigger [...]
A team of astronomers from the National Centre for Radio Astrophysics (NCRA-TIFR) in Pune, and the Raman Research Institute (RRI), in Bangalore, has used the Giant Metrewave Radio Telescope (GMRT) to measure the atomic hydrogen gas content of galaxies 9 billion years ago, in the young universe. This is the earliest epoch in the universe for which there is a measurement of the atomic hydrogen content of galaxies. The new result is a crucial [...]
Scientists from the National Centre for Radio Astrophysics of the Tata Institute of Fundamental Research (NCRA-TIFR), Pune used the upgraded Giant Metrewave Radio Telescope (uGMRT) to determine that AT 2018cow, the first of a newly discovered class of cosmic explosions, has an extremely patchy environment. Sources like AT 2018cow release an enormous amount of energy, nonetheless fade extremely rapidly. This along with their extremely blue color [...]
