The Critical Mass in Galaxy Evolution
Preetish K. Mishra, Changbom Park, Jaehyun Lee +4
We investigate the physical origin of critical mass, a threshold where many galaxy properties and scaling relations undergo fundamental transitions, using the Horizon Run 5 simulat…
Chemical signature reveals co-spatial dwarf satellite of an edge-on disc galaxy with MUSE
Devang Somawanshi, Souradeep Bhattacharya, Manish Kataria +2
Integral field unit (IFU) spectroscopic observations of resolved galaxies provide an optimal experimental setting for determination of stellar population properties, in particular…
Emergence of the Galaxy Morphology-Star Formation Activity-Clustercentric Radius Relations in Galaxy Clusters
Sungwook E. Hong, Changbom Park, Preetish K. Mishra +7
We investigate when and how the relations of galaxy morphology and star forming activity with clustercentric radius become evident in galaxy clusters. We identify 162 galaxy cluste…
Stellar mass dependence of galaxy size-dark matter halo radius relation probed by Subaru-HSC survey weak lensing measurements
Preetish K. Mishra, Divya Rana, Surhud More
We investigate the stellar mass-dependence of the galaxy size-dark matter halo radius relation for low redshift galaxies using weak gravitational lensing measurements. Our sample c…
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…
Pseudo bulges in galaxy groups: the role of environment in secular evolution
Preetish K. Mishra, Yogesh Wadadekar, Sudhanshu Barway
We examine the dependence of the fraction of galaxies containing pseudo bulges on environment for a flux limited sample of 5000 SDSS galaxies. We have separated bulges into c…
