The GMRT CAT1-COSMOS Survey: HI 21 cm emission from star-forming galaxies at in the COSMOS field
Balpreet Kaur, Nissim Kanekar, Aditya Chowdhury +1
We report a 216-hr upgraded Giant Metrewave Radio Telescope (GMRT) Band-4 MHz observation of the COSMOS field, using 7 GMRT pointings to cover an area of sq. deg.,…
The HI Mass Function of Star-forming Galaxies at
Aditya Chowdhury, Nissim Kanekar, Jayaram N. Chengalur
We present the first estimate, based on direct HI 21 cm observations, of the HI mass function (HIMF) of star-forming galaxies at , obtained by combining our measurement…
The Gas Accretion Rate of Galaxies over
Aditya Chowdhury, Nissim Kanekar, Jayaram N. Chengalur
We present here estimates of the average rates of accretion of neutral gas onto main-sequence galaxies and the conversion of atomic gas to molecular gas in these galaxies at two ke…
Atomic Gas Scaling Relations of Star-forming Galaxies at
Aditya Chowdhury, Nissim Kanekar, Jayaram Chengalur
We use the Giant Metrewave Radio Telescope (GMRT) Cold-HI AT (CAT) survey, a 510 hr HI 21cm emission survey of galaxies at , to report the first measur…
Atomic Gas Dominates the Baryonic Mass of Star-forming Galaxies at
Aditya Chowdhury, Nissim Kanekar, Jayaram N. Chengalur
We present a comparison between the average atomic gas mass, (including HI and He), the average molecular gas mass, , and the aver…
The Giant Metrewave Radio Telescope Cold-HI AT Survey
Aditya Chowdhury, Nissim Kanekar, Jayaram N. Chengalur
We describe the design, data analysis, and basic results of the Giant Metrewave Radio Telescope Cold-HI AT (GMRT-CAT1) survey, a 510-hour upgraded GMRT HI 21 cm emis…
Insufficient Gas Accretion Caused the Decline in Cosmic Star-Formation Activity 8 Billion Years Ago
Aditya Chowdhury, Nissim Kanekar, Jayaram N. Chengalur
Measurements of the atomic hydrogen (HI) properties of high-redshift galaxies are critical to understanding the decline in the star-formation rate (SFR) density of the Universe aft…
Giant Metrewave Radio Telescope Detection of HI 21 cm Emission from Star-forming Galaxies at
Aditya Chowdhury, Nissim Kanekar, Barnali Das +2
We report a -hour Giant Metrewave Radio Telescope (GMRT) search for HI 21 cm emission from star-forming galaxies at in seven fields of the DEEP2 Galaxy…
HI 21-centimetre emission from an ensemble of galaxies at an average redshift of one
Aditya Chowdhury, Nissim Kanekar, Jayaram Chengalur +2
The baryonic processes in galaxy evolution include gas infall onto galaxies to form neutral atomic hydrogen (HI), the conversion of HI to the molecular state (H), and, finally,…
Giant Metrewave Radio Telescope detections of two high-opacity HI 21cm absorbers at
Aditya Chowdhury, Nissim Kanekar, Jayaram Chengalur
We report the discovery of two remarkable high-opacity HI 21cm absorbers against low-luminosity active galactic nuclei (AGNs), at towards J0229+0044 and at …
A High Resolution Study of Carbon Radio Recombination Lines towards Cassiopeia A
Aditya Chowdhury, Jayaram N. Chengalur
Carbon Radio Recombination Lines trace the interface between molecular and atomic gas. We present GMRT observations of Carbon Radio Recombination Lines (CRRL), C244-C250 towa…
A Dearth of Atomic Hydrogen in NGC1052-DF2
Aditya Chowdhury
The recently claimed discovery of an ultra-diffuse galaxy lacking dark matter has important implications for alternate theories to dark matter as well as models of galaxy formation…
Angular Momentum Content in Gas Rich Dwarf Galaxies
Aditya Chowdhury, Jayaram N. Chengalur
We derive the specific baryonic angular momentum of five gas rich dwarf galaxies from HI kinematics complemented by stellar mass profiles. Since the gas mass of these galaxies is m…
