Probing cold gas and dust in quiescent galaxies across cosmic time
Anita Zanella, Sirio Belli, Belen Alcalde Pampliega +35
The discovery of massive quiescent galaxies at high redshift by JWST has revealed that star formation can cease rapidly in the early Universe, yet the physical mechanisms responsib…
Unveiling the Baryon Cycle Through Cosmic Time
Manuel Aravena, Leindert A. Boogaard, Jorge González-López +28
Galaxy evolution is governed by the baryon cycle: gas accreted from the cosmic web and circumgalactic medium condenses into molecular gas, forms stars, and is redistributed by stel…
What fuels the growth of stars and black holes in galaxies through cosmic time? The physics and chemistry of the interstellar medium in distant galaxies
Leindert A. Boogaard, Manuel Aravena, Matus Rybak +25
The interplay between the baryonic matter in galaxies (gas, dust, stars) has a fundamental role in our understanding of galaxy formation and evolution through cosmic time. The (sub…
The dawn of the first galaxies
Livia Vallini, Tanio Diaz Santos, Belen Alcalde Pampliega +56
Understanding how the first galaxies assembled their stellar mass at cosmic dawn is a central frontier of modern astrophysics. JWST has now revealed an unexpected population of ult…
Vz-GAL Dusty Star-Forming Galaxies: Revisiting the CO-H2 Conversion Factor Tension
Prachi Prajapati, Axel Weiss, Dominik Riechers +17
The CO luminosity-to-H mass conversion factor () remains a debated uncertainty in determining molecular gas masses of high-redshift dusty star-forming galaxies (DSFGs).…

A summary of instruments proposed for observing pulsating variables from the Mt. Abu Observatory
Anwesh Kumar Mishra, Deekshya Roy Sarkar, Prachi Prajapati +3
Pulsating variables play a significant role in shaping modern astronomy. Presently it is an exciting era in observational study of variable stars owing to surveys like OGLE and TES…
HerS-3: An Exceptional Einstein Cross Reveals a Massive Dark Matter Halo
P. Cox, K. M. Butler, C. R. Keeton +24
We present a study of HerS-3, a dusty star-forming galaxy at zspec = 3.0607, which is gravitationally amplified into an Einstein cross with a fifth image of the background galaxy s…
Vz-GAL: Probing Cold Molecular Gas in Dusty Star-forming Galaxies at z=1-6
Prachi Prajapati, Dominik Riechers, Pierre Cox +20
We present the first results of Vz-GAL, a high-redshift CO(J=1-0) large survey with the Karl G. Jansky Very Large Array, targeting 92 Herschel-selected, infrared-luminous, dusty st…
Study of Wolf-Rayet stars using uGMRT
Anindya Saha, Anandmayee Tej, Santiago del Palacio +4
In recent years, systems involving massive stars with large wind kinetic power have been considered as promising sites for investigating relativistic particle acceleration in low r…
Optical polarisation study of Galactic Open clusters
Namita Uppal, Shashikiran Ganesh, Santosh Joshi +3
Dust is a ubiquitous component in our Galaxy. It accounts for only mass of the ISM but still is an essential part of the Galaxy. It affects our view of the Galaxy by obscurin…
Search for particle acceleration in two massive Wolf-Rayet stars using uGMRT observations
Anindya Saha, Anandmayee Tej, Santiago del Palacio +4
Large wind kinetic power of Wolf-Rayet (WR) stars make them ideal targets in low radio frequencies to search for non-thermal emission due to relativistic particle acceleration. In…
