Collisions between galaxies: A frequent phenomenon than we expected earlier
Initially, early-type galaxies were considered aged, evolved systems with a reddish appearance, primarily comprising older stars and lacking young star formation due to limited gas and dust resources. However, contemporary techniques, such as integral field spectroscopy for studying star motion...
Utilization of Navigation with Indian Constellation (NavIC) for space weather and upper atmospheric studies
Ionospheric irregularity studies are important aspects for understanding ionospheric physics and related processes, especially near the low-latitude regions. This work, for the first time, shows the nature of the ionospheric irregularities present during these observation days and sets a path...
Origin of ultra-bright blazar emissions: An astronomer’s glimpse into cosmic volcanoes
Blazars are a rare class of active galactic nuclei (AGN), in which the jets are pointed directly toward our line of sight, making them one of the brightest yet extremely compact sources. Relativistic effects such as beaming makes the jet...
The Ghost of a Star Screams 6 Days After Its Death
Dying heavy stars forms black holes and sometimes emit jets, producing very narrow-angle flashes of gamma rays known as Gamma-Ray Bursts (GRBs). This article summarises the findings from the follow-up of such a GRB 210204A. The GRB showed typical afterglow...
Looking at five radio-quiet AGN through the polarization lens
This article discusses the results from our combined radio polarization and emission line study of five type-2 radio-quiet quasars. We investigate the origin of radio emission in these sources and understand what impact the local gaseous environments have on the...
Investigating the massive plasma blobs from the Sun using an ‘in-situ’ eye
This article is about investigating the characteristics of Interplanetary Coronal Mass Ejections using in-situ observation. ICMEs are well-known to expand as they propagate through the heliosphere. Despite this, their cross-sections are usually modeled as static plasma columns within the magnetohydrodynamics...
