Collisionless whistler heat-flux instability in ultra-high- plasmas
Rhisiart Davies, Prakriti Pal Choudhury, Archie F. A. Bott
Kinetic instabilities, notably the whistler heat-flux instability (WHFI), are known to suppress thermal transport significantly in the moderate- to high- plasmas relevant to man…
Latent thermal instability
Prakriti Pal Choudhury, Archie F. A. Bott
Multiscale temperature fluctuations are abundant in the intracluster medium (ICM) outside of galaxy cluster cores (). Their origin is often attributed to turbul…
Modeling transport in weakly collisional plasmas using thermodynamic forcing
Prakriti Pal Choudhury, Archie F. A. Bott
How momentum, energy, and magnetic fields are transported in the presence of macroscopic gradients is a fundamental question in plasma physics. Answering this question is especiall…
Cold fronts in galaxy clusters I: A case for the large-scale global eigen modes in unmagnetized and weakly magnetized cluster core
Prakriti Pal Choudhury, Christopher S. Reynolds
Galaxy clusters show large-scale azimuthal X-ray surface brightness fluctuations known as cold fronts. Cold fronts are argued to originate due to sloshing driven by sub-halo passag…
Acoustic waves and g-mode turbulence as energy carriers in a viscous intracluster medium
Prakriti Pal Choudhury, Christopher S. Reynolds
Many recent works on the observed galaxy clusters in the X-rays highlight broadly two classes of exclusive energy carriers - sound waves and turbulence. In order to understand this…
Shatter or not: role of temperature and metallicity in the evolution of thermal instability
Hitesh Kishore Das, Prakriti Pal Choudhury, Prateek Sharma
We test how metallicity variation (a background gradient and fluctuations) affects the physics of local thermal instability using analytical calculations and idealized, high-resolu…
A 1-dimensional hydrodynamic model for accretion, cooling and heating of gas in dark matter halos from to
Prakriti Pal Choudhury, Guinevere Kauffmann, Prateek Sharma
We study an idealized 1D model for the evolution of hot gas in dark matter halos for redshifts . We introduce a numerical setup incorporating cosmological accretion of gas…
Cold gas in cluster cores: Global stability analysis and non-linear simulations of thermal instability
Prakriti Pal Choudhury, Prateek Sharma
We perform global linear stability analysis and idealized numerical simulations in global thermal balance to understand the condensation of cold gas from hot/virial atmospheres (co…
