Second time one of the radio images I created has been selected for cover page of A&A @AandA_journal. Here, you can see multifrequency radio images of giant radio galaxy with ~300 kpc jets made using #GMRT data. @NCRA_Outreach
Cover: Barbell GRG: SDSS (yellow), GMRT (red jet and blue) (Dabhade, P., et al., 2022, A&A, 668, A64)

Delighted to share our AASKAII chapter, โTracing the Cosmic Web across Cosmic Time through SKA Observations of Radio Galaxies.โ We outline how the SKA will use radio galaxies to probe large-scale structure, environments and cosmic magnetism.

SKA-India Science Meeting titled โIndia and the SKA: Preparing for a Transformative Era in Astrophysicsโ has just been kick-started today morning (15th Jan 2026) at @IiserMohali . Prof. @yash_gupta_62 of @NCRA_Outreach introduced...(contd.)

What comes after paper I? Paper II, still led by @e_derubeis
In the new paper, a more detailed investigation about the origin of the filaments is done by combining @LOFAR data with new uGMRT and VLA observations at higher frequency

Thin filaments in the tails of A2255, by @e_derubeis+ (w/ myself++)
A2255 is known to be a "mess" (arxiv.org/abs/2006.04808). The new @LOFAR-VLBI images add further complexity in the system, this time revealing small-scale structures in its radio galaxies

SAGAN VI (led by PhD student @MousumiMahato10, Tartu Observatory) is accepted in @AandA_journal
A study linking GRG growth to the cosmic web using full 3D geometry, from sample curation to statistics to some truly elegant visualisation.

The Indian astronomy community mourns the passing of Prof. J.V. Narlikar, a luminary in astrophysics & cosmology, institution builder, science communicator par excellence. His founding of IUCAA & efforts to promote astronomy in universities transformed Indian science.

Donโt miss this chance to explore the forefront of #gravitationalwavescience and see where history is being made! ๐
Last month, it was a pleasure to deliver a seminar at the Jagiellonian University Observatory and interact with Prof. Machalski, Prof. Jamrozy, Dr. Kuลบmicz, and @self_calibrated.
We had productive #GRGs discussions that set plans in motion for exciting future collaborations!
Visited the Nicolaus Copernicus University in Torun (Poland) to deliver a seminar and had the chance to see the 32m radio telescope(part of #EVN) at Piwnice. Grateful to Maciej Koprowski for the invitation and @kasia_malek for suggesting this visit. A truly memorable experience!

Great to be at @camkpan for the Rubin-LSST Polish Consortium Meeting 2024! Knut Olsen (@knutenator of @NOIRLabAstro) gave an insightful overview of the Rubin Observatory @VRubinObs and #LSST. Agnieszka Pollo (of @ncbj_swierk) highlighted Polandโs growing role in LSST. #Astronomy

Astronomers have spotted the biggest pair of black hole jets ever seen, spanning 23 million light-years in total length. That's equivalent to lining up 140 Milky Way galaxies back to back.

Exciting read! This paper by Prof Gopal-Krishna takes us back 40+ years to the origins of 'Gigahertz-Peaked-Spectrum' (GPS) sources, a key subclass of radio galaxies. Read about the discovery, milestones, and recent advances!
