Star-forming S0 Galaxies in SDSS-MaNGA: fading spirals or rejuvenated S0s?
Himansh Rathore, Kavin Kumar, Preetish K. Mishra +2
We investigate the origin of rare star-formation in an otherwise red-and-dead population of S0 galaxies using spatially resolved spectroscopy. Our sample consists of low reds…
Predicting bulge to total luminosity ratio of galaxies using deep learning
Harsh Grover, Omkar Bait, Yogesh Wadadekar +1
We present a deep learning model to predict the r-band bulge-to-total light ratio (B/T) of nearby galaxies using their multi-band JPEG images alone. Our Convolutional Neural Networ…
Connecting galaxy structure and star formation: the role of environment in formation of S0 galaxies
Preetish K. Mishra, Yogesh Wadadekar, Sudhanshu Barway
In this work, we investigate the reason behind the increased occurrence of S0 galaxies in high density environments. Our sample comprises of 2500 spiral and 2000 S0 g…
Why are classical bulges more common in S0 galaxies than in spiral galaxies?
Preetish K. Mishra, Yogesh Wadadekar, Sudhanshu Barway
In this paper, we try to understand why the classical bulge fraction observed in S0 galaxies is significantly higher than that in spiral galaxies. We carry out a comparative study…
Detection of Low Metallicity Warm Plasma in a Galaxy Overdensity Environment at z ~ 0.2
Anand Narayanan, Blair D. Savage, Preetish K. Mishra +3
We present results from the analysis of a multiphase O VI - broad Ly-alpha absorber at z = 0.19236 in the HST/COS spectrum of PG 1121+422. The low and intermediate ionization metal…
Age bimodality in the central region of pseudobulges in S0 galaxies
Preetish K. Mishra, Sudhanshu Barway, Yogesh Wadadekar
We present evidence for bimodal stellar age distribution of pseudobulges of S0 galaxies as probed by the index. We do not observe any bimodality in age distribution for…
