GMRT Archive Processing Project
Shubhankar Deshpande, Yogesh Wadadekar, Huib Intema +7
The GMRT Online Archive now houses over 120 terabytes of interferometric observations obtained with the GMRT since the observatory began operating as a facility in 2002. The utilit…
Outlying H blobs in SDSS IV MaNGA
Omkar Bait, Yogesh Wadadekar, Sudhanshu Barway
We have discovered a population of 29 outlying H emitters which appear like unresolved blobs in the DR14 data release of the SDSS IV MaNGA integral field unit survey. They do no…
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…
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…
