Star-dust geometry main determinant of dust attenuation in galaxies
Sonali Sachdeva, Biman B. Nath
Analysing a large representative sample of local galaxies (8707), we find that the variation in the shape of their dust attenuation curves is driven primarily by their structure, i…
Correlation of structure and stellar properties of galaxies in Stripe 82
Sonali Sachdeva, Luis C. Ho, Yang A. Li +1
Establishing a correlation (or lack thereof) between the bimodal colour distribution of galaxies and their structural parameters is crucial to understand the origin of bimodality.…
Formation of disc galaxies around z~2
Sonali Sachdeva, Rupjyoti Gogoi, Kanak Saha +2
We present combined evolution of morphological and stellar properties of galaxies on the two sides of z=2 (2.0<z<4.0 and 1.5<z<2.0) in CDFS, with ground-based spectroscopic redshif…
Bright Compact Bulges (BCBs) at intermediate redshifts
Sonali Sachdeva, Kanak Saha
Studying bright (), intermediate-redshift (), disc dominated () galaxies from HST/ACS and WFC3 in Chandra Deep Field South, in rest-frame B and I-band,…
Growth of bulges in disc galaxies since
Sonali Sachdeva, Kanak Saha, Harinder P. Singh
We investigate the growth of bulges in bright () disc galaxies since , in rest-frame B and I-band, using images from HST ACS and WFC3 in GOODS-South for high redsh…
Survival of pure disk galaxies over the last 8 billion years
Sonali Sachdeva, Kanak Saha
Pure disk galaxies without any bulge component, i.e., neither classical nor pseudo, seem to have escaped the affects of merger activity inherent to hierarchical galaxy formation mo…
Thirty Meter Telescope International Observatory Detailed Science Case 2024
Warren Skidmore, Bob Kirshner, David Andersen +168
The Thirty Meter Telescope (TMT) International Observatory (TIO) will be a revolutionary leap forward in astronomical observing capabilities, enabling us to address some of the mos…
The evolution of disc galaxies with and without classical bulges since z~1
Sonali Sachdeva, Dimitri A. Gadotti, Kanak Saha +1
Establishing the relative role of internally and externally driven mechanisms responsible for disc and bulge growth is essential to understand the evolution of disc galaxies. In th…
Magnitude and size evolution of bulgeless galaxies
Sonali Sachdeva
We examine the magnitude and size evolution of bulgeless (discs with no-bulge or pseudo-bulge) galaxies up to z~0.9 in rest-frame B-band. Their evolution is compared to that of nor…
