Photometric identification of compact galaxies, stars and quasars using multiple neural networks
Siddharth Chaini, Atharva Bagul, Anish Deshpande +4
We present MargNet, a deep learning-based classifier for identifying stars, quasars and compact galaxies using photometric parameters and images from the Sloan Digital Sky Survey (…
Gravitational interaction signatures in isolated galaxy triplet systems: a photometric analysis
Amira A. Tawfeek, Kanak Saha, Kaustubh Vaghmare +7
Galaxy triplets are interesting laboratories where we can study the formation and the evolution of small and large systems of galaxies. This study aims to investigate signs of inte…
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…
A SALT Spectral Study of S0s Hosting Pseudobulges
Kaustubh Vaghmare, Sudhanshu Barway, Petri Väisänen +3
We present a SALT-RSS spectroscopic study of a sample of S0 galaxies established by Vaghmare et al. (2015) as having pseudobulges using a combination of photometric criteria. We ex…
The MeerKAT Absorption Line Survey (MALS)
N. Gupta, R. Srianand, W. Baan +41
Deep galaxy surveys have revealed that the global star formation rate (SFR) density in the Universe peaks at 1 < z < 2 and sharply declines towards z = 0. But a clear picture of th…
Which bulges are favoured by barred S0 galaxies?
Sudhanshu Barway, Kanak Saha, Kaustubh Vaghmare +1
S0 galaxies are known to host classical bulges with a broad range of size and mass, while some such S0s are barred and some not. The origin of the bars has remained as a long-stand…
