In orbit performance of UVIT over the 5 years
S. K. Ghosh, P. Joseph, A. Kumar +21
Over the last 5 years, UVIT has completed observations of more than 500 proposals with ~ 800 unique pointings. In addition, regular planned monitoring observations have been made a…
More insights into bar quenching. Multi-wavelength analysis of four barred galaxies
Koshy George, P. Joseph, C. Mondal +3
The underlying nature of the process of star formation quenching in the central regions of barred disc galaxies that is due to the action of stellar bar is not fully understood. We…
The role of environment on quenching, star formation and AGN activity
Bianca M. Poggianti, Callum Bellhouse, Tirna Deb +10
Galaxies undergoing ram pressure stripping in clusters are an excellent opportunity to study the effects of environment on both the AGN and the star formation activity. We report h…
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…
