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...


'Where’s the Shadow?' - A workshop in preparation for Zero Shadow Day

The Cosmology Education and Research Training Centre (COSMOS) is an upcoming state-of-the-art planetarium, along with a data training centre and resource centre in Mysuru. The Indian Institute of Astrophysics (IIA) has formed an Education and Public Outreach Committee (EPOC) for...


India’s expanding Cosmology community

‘Frontiers in Cosmology’ was a five-day international conference held at Raman Research Institute (RRI) during February 20 – 24, 2023. More than 100 participants including researchers, scientists, students and faculties from around the world attended the meet.
