Detection of polarized quasi-periodic microstructure emission in millisecond pulsars
Kishalay De, Yashwant Gupta, Prateek Sharma
Microstructure emission, involving short time scale, often quasi-periodic, intensity fluctuations in subpulse emission, is well known in normal period pulsars. In this letter, we p…
AGN jet-driven stochastic cold accretion in cluster cores
Deovrat Prasad, Prateek Sharma, Arif Babul
Several arguments suggest that stochastic condensation of cold gas and its accretion onto the central supermassive black hole (SMBH) is essential for active galactic nuclei (AGN) f…
Clusters of galaxies and the cosmic web with SKA
Ruta Kale, K. S. Dwarakanath, Dharam Vir Lal +7
The intra-cluster and inter-galactic media (ICM, IGM) that pervade the large scale structure of the Universe are known to be magnetised at sub-micro Gauss to micro Gauss levels and…
Clues to the origin of Fermi Bubbles from OVIII/OVII line ratio
Kartick C. Sarkar, Biman B. Nath, Prateek Sharma
We constrain the origin of Fermi Bubbles using 2D hydrodynamical simulations of both star formation driven and black hole accretion driven wind models. We compare our results with…
Molecular outflows in starburst nuclei
Arpita Roy, Biman B. Nath, Prateek Sharma +1
Recent observations have detected molecular outflows in a few nearby starburst nuclei. We discuss the physical processes at work in such an environment in order to outline a scenar…
How radiation affects superbubbles: Through momentum injection in early phase and photo-heating thereafter
Siddhartha Gupta, Biman B. Nath, Prateek Sharma +1
Energetic winds and radiation from massive star clusters push the surrounding gas and blow superbubbles in the interstellar medium (ISM). Using 1-D hydrodynamic simulations, we stu…
