AstroSat detection of Lyman continuum emission from a z=1.42 galaxy
Kanak Saha, Shyam N. Tandon, Charlotte Simmonds +10
One of the outstanding problems of current observational cosmology is to understand the nature of sources that produced the bulk of the ionizing radiation after the Cosmic Dark Age…
Fate of stellar bars in minor merger of galaxies
Soumavo Ghosh, Kanak Saha, Paola Di Matteo +1
Minor merger of galaxies are common during the evolutionary phase of galaxies. Here, we investigate the dynamical impact of a minor merger (mass ratio 1:10) event on the final fate…
Wobbly discs -- corrugations seen in the dust lanes of edge-on galaxies
Chaitra A. Narayan, Ralf-Juergen Dettmar, Kanak Saha
We report the detection of small scale bending waves, also known as corrugations, in the dust lanes of five nearby edge-on disc galaxies. This phenomenon, where the disc mid-plane…
Bar rejuvenation in S0 galaxies?
Sudhanshu Barway, Kanak Saha
Based on the colour measurements from a multi-band, multi-component 2D decomposition's of S0 and spiral galaxies using SDSS images, we found that bars are bluer in S0 galaxies comp…
