Main Research Areas: 

Nilkanth Vagshette works mainly in the area of Observational Extragalactic Astronomy. His specific interests are AGN feedback and cooling flow mechanism in groups and cluster of galaxies, star formation activity in early-type galaxies and the evolution of galaxies.


Nilkanth Vagshette obtained an M.Sc. in Physics from the School of Physical Sciences, Swami Ramanand Teerth Marathwada University, Nanded, in 2006. He completed his doctoral studies and obtained a Ph.D. in Physics at the same university in 2012, after which he joined IUCAA, Pune as a project post-doctoral fellow for 3 years. Then moved to the PRL, Ahmedabad for another postdoc under Prof. Sachindra Naik. Also, awarded Young Scientist Award, SERB, Department of Science and Technology, Government of India. In 2018 he joined as Assistant Professor, Maharashtra Udayagiri Mahavidyalaya, Udgir, Latur, India – 413517

Research description:

His research interests are in galaxy groups and clusters. This study is based on multiwavelength data. Currently, involved in the following research topics:

  1. Feedback from active galactic nuclei (AGN):

The issue of AGN feedback is not yet fully understood. Despite extensive discussions in the literature, it is still not clear how an AGN transfers its power to the diffuse ambient plasma. Recently, there has been great interest in the process of “AGN feedback”, its role in galaxy formation, and the possibility that AGN feedback solves the over-cooling problem. Key issues include the effect of AGN feedback in regulating the cooling of the intra-cluster medium, how AGNs are fuelled in groups and clusters, and the physics of the balance between heating and cooling process in the cores of groups and clusters. I am currently involved studies of samples of groups and clusters that that aims to improve our understanding of AGN feedback processes.

  1. X-ray Instrumentation:

He has been involved in developmental work to the Indian space astronomy mission (ASTROSAT). My contribution has mainly been in calibrating the Cadmium Zinc Telluride coded-mask image (CZTI) detector. Which covers hard X-rays from 10 to 150 keV energy band.
