Understanding the emissions in Black hole binaries
Yash Bhargava from Inter-University Centre for Astronomy and Astrophysics (IUCAA), Pune, takes us through the journey of the death of a star in this wonderful article about his work.
Anyway the plasma moves - it does really matter!
Light when seen correctly provides rich information on what happens in the cosmos. In this article, we showcase our work on identifying signatures of the solar wind in the solar chromosphere – far lower in the solar atmosphere than what...
SARAS 3 telescope refutes astrophysical origins of the claimed cosmic dawn signal
SARAS 3 experiment, designed and developed at Raman Research Institute, has conclusively refuted the claim of detection of the signal from cosmic dawn by EDGES experiment. It has become the first experiment worldwide to reach the required sensitivity and cross-verify...
Bending of Cosmic fountains, giving birth to a peculiar X-shaped galaxy
When observed with a radio telescope, a giant peculiar X-shaped morphology is seen in some galaxies. It is difficult to understand what gives rise to such peculiar morphology; And, to date, this is a topic of debate among astronomers themselves....
How much Metal does the Quiet Sun Corona contain?
XSM onboard Chandrayaan-2 observed the Sun during the deepest solar minimum of the past century from in 2019-2020. By studying the XSM spectra for the days when the Sun was very quiet, researchers have found that the abundances of all...
EARTH-SIZED TELESCOPES FOR ASTRONOMICAL OBSERVATIONS IN THE LOW RADIO FREQUENCIES
The study of the cosmos is only complete when we can receive and analyse data from the entire electromagnetic spectrum, ranging from picometer-sized gamma rays to several meters long radio waves. This realization is what led to the advent of...
