Biography:
Sameer obtained a B.Sc. (Physics) in 2011, an M.Sc.(Physics) in 2014, and an M.Phil. (Physics) in 2018, all from the Savitribai Phule Pune University. He carried out his doctoral research at the Savitribai Phule Pune University, obtaining his Ph.D. in 2023. He joined NCRA-TIFR in January 2023 as Post-doctoral Fellow.

Research Description:
Observations of diffuse synchrotron radio emissionfrom large-scale structures (LSS's) in the Universe have provided important cluesabout the presence of cosmic magnetic fields and relativistic electrons in the thin intergalactic medium. These observations have raised several crucial questions,such as the mechanism behind particle acceleration, the source of electrons for the acceleration, and the understanding of the magnetic field. The production of various synchrotron radio sources, such as radio halos and relics observedin the intra-cluster medium (ICM), is believed to be linked to cluster mergers. However, the exact physical processes responsible for the origin of such diffusecluster radio sources are still poorly understood, despite most of the current data supporting this hypothesis. The discovery of relaxed and even poor clusters with similar radio structures has been aided by the development of highly sensitive radio telescopes in recent times, even though strong correlations between the cluster radio emission and both the dynamical activity and the cluster mass have been reported in the last decade, disfavouring such observations. To understand this dichotomy, we observe and study such cosmic structures ranging from galaxy groups through low-mass clusters, massive clusters, and up to superclusters, mainly in the radio bands.
