uGMRT unravels the eclipses of millisecond pulsars in compact binary

Eclipses in spider millisecond pulsars (MSPs) have been known over decades, but the true mechanism for the eclipses was still a mystery. A group of scientists from NCRA-TIFR distinctively identify the physical mechanism behind the frequency dependent eclipses observed in spider MSPs using the wide bandwidth observations using uGMRT for the first time. Using the broadband radio spectra, they also determined some of the physical properties of the [...]

Giant Magnetic Pulse Rounds up Spins Far and Wide

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 [...]

Discovery of a Remnant Radio Galaxy using the GMRT

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.

Watching the Ultrafast Dance Moves of a Laser Plasma

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 [...]

GMRT measures the atomic hydrogen gas mass in galaxies 9 billion years ago

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 [...]
