Additional Calibration of the Ultra-Violet Imaging Telescope on board AstroSat
S. N. Tandon, J. Postma, P. Joseph +20
Results of the initial calibration of the Ultra-Violet Imaging Telescope (UVIT) were reported earlier by Tandon et al. (2017). The results reported earlier were based on the ground…
Calibration of ground based survey data using Gaia: Application to DES
Koshy George, Thomas Vassallo, Joseph Mohr +4
The calibration of ground based optical imaging data to photometric accuracy of 10 mmag over the full survey area and to color uniformity better than 5 mmag on the scale of the VIS…
GASP XXIII: A jellyfish galaxy as an astrophysical laboratory of the baryonic cycle
Bianca M. Poggianti, Alessandro Ignesti, Myriam Gitti +18
With MUSE, Chandra, VLA, ALMA and UVIT data from the GASP programme we study the multiphase baryonic components in a jellyfish galaxy (JW100) with a stellar mass 3.2 X 10^{11} M_su…
Significance of bar quenching in the global quenching of star formation
Koshy George, Smitha Subramanian, K. T. Paul
The suppression of star formation in the inner kiloparsec regions of barred disk galaxies due to the action of bars is known as bar quenching. We investigate here the significance…
Tracing the outer disk of NGC 300: An ultraviolet view
Chayan Mondal, Annapurni Subramaniam, Koshy George
We present an ultra-violet (UV) study of the galaxy NGC~300 using GALEX far-UV (FUV) and near-UV (NUV) observations. We studied the nature of UV emission in the galaxy and correlat…
UVIT view of dwarf irregular galaxy IC 2574 : Is the star formation triggered due to expanding HI shells?
Chayan Mondal, Annapurni Subramaniam, Koshy George
Star forming dwarf galaxies in the local volume are diverse and are ideal test beds to understand details of star formation in a variety of environments. Here, we present a deep FU…
