A Massive Galaxy at the Edge of Feedback-Free Efficiency
K. Aditya, Kartick C. Sarkar
The efficiency with which galaxies convert their available baryonic reservoir into stars sets a fundamental ceiling on stellar mass assembly in the early Universe and encodes the c…
Feeding and Feedback in Dwarf Galaxies (FeeD) -- I. Evidence of nuclear ultra-fast and galaxy-scale outflows in the dwarf galaxy Arp 151
Santanu Mondal, Ankit Patel, Mar Mezcua +5
Feeding and feedback regulated by supermassive black holes (SMBHs) play a central role in galaxy growth and evolution, yet these processes remain poorly understood in low-mass gala…
HI 21 cm observations and dynamical models of superthin galaxies
K Aditya
The primary objective of this thesis is to identify the key dynamical mechanisms responsible for the superthin stellar discs. We use HI 21cm radio-synthesis observations and stella…
\HI{} 21cm observations and dynamical modelling of the thinnest galaxy: FGC 2366
K. Aditya, Arunima Banerjee, Peter Kamphuis +3
Superthin galaxies are bulgeless low surface brightness galaxies with unusually high major-to-minor axes ratio of the stellar disc, i.e.,. We present Giant Metrewave Rad…
How "cold" are the stellar discs of superthin galaxies?
K. Aditya, Arunima Banerjee
Superthin galaxies are a class of bulgeless, low surface brightness galaxies with strikingly high values of planar-to-vertical axes ratio , possibly indicating t…
