How Magnetic Fields Regulate Cooling and Mixing in Turbulent Radiative Mixing Layers
Rajsekhar Mohapatra, Lachlan Lancaster, Drummond Fielding +2
Turbulent radiative mixing layers (TRMLs) are expected wherever hot and cold gas move past one another, including in the solar corona, galactic winds, and cold filaments in galaxy…
A Comparative Study of Isothermal Turbulence Statistics: Fourier Space Driving vs. Point Source Driving
Tejahni Desire, Chang-Goo Kim, Rajsekhar Mohapatra
The turbulence driving parameter (; the ratio of the density to velocity fluctuations) is widely used to infer the dominant mode of ene…
The Origin of Da Scaling: Suppressed Cooling in Fast-Cooling Mixing Layers
Lachlan Lancaster, Drummond B. Fielding, Rajsekhar Mohapatra +1
In numerical experiments simulating Turbulent Radiative Mixing Layers (TRMLs) it is observed that as the cooling time in the mixed gas, , becomes very short compared…
Ceci n'est pas une Couche de Mélange: The Meaning of Resolved Turbulent Radiative Mixing
Lachlan Lancaster, Rajsekhar Mohapatra, Drummond B. Fielding +1
Turbulent Radiative Mixing Layers (TRMLs) are of fundamental importance to the transport of energy and momentum in multi-phase, astrophysical fluids. We use measurements of the "mi…
Multiphase gas in Circumgalactic cloud complexes: Insights from kiloparsec-scale Magnetohydrodynamic Turbulence Simulations
Rajsekhar Mohapatra, Alankar Dutta, Prateek Sharma
The circumgalactic medium (CGM) is the diffuse gas surrounding a galaxy's halo, and it plays a vital role in the galactic baryon cycle. However, its mass distribution across the vi…
XMAGNET: Velocity structure functions of active galactic nucleus-driven turbulence in the multiphase intracluster medium
M. Fournier, P. Grete, M. Brüggen +5
Significant theoretical and observational efforts are underway to investigate the properties of turbulence in the hot plasma that pervades galaxy clusters. Spectroscopy has been us…
The Type Ia Supernova and Asymptotic Giant Branch Stellar Ejecta-regulated Interstellar Medium of Massive Galaxies
Rajsekhar Mohapatra, Eliot Quataert, Drummond Fielding +1
Observations and theory suggest that Type Ia supernovae (SNIa) heating and mass loss from asymptotic giant branch (AGB) stars play a crucial role in the interstellar medium (ISM) o…
Multiphase gas in elliptical galaxies: the role of Type Ia supernovae
Rajsekhar Mohapatra, Eliot Quataert
Massive elliptical galaxies harbor large amounts of hot gas () in their interstellar medium (ISM) but are typically quiescent in star formation. Active-gal…
Multiphase condensation in cluster halos: interplay of cooling, buoyancy and mixing
Rajsekhar Mohapatra, Prateek Sharma, Christoph Federrath +1
Gas in the central regions of cool-core clusters and other massive halos has a short cooling time (). Theoretical models predict that this gas is susceptibl…
Multiphase turbulence in galactic halos: effect of the driving
Rajsekhar Mohapatra, Christoph Federrath, Prateek Sharma
Supernova explosions, active galactic nuclei jets, galaxy--galaxy interactions and cluster mergers can drive turbulence in the circumgalactic medium (CGM) and in the intracluster m…
Velocity structure functions in multiphase turbulence: interpreting kinematics of H filaments in cool core clusters
Rajsekhar Mohapatra, Mrinal Jetti, Prateek Sharma +1
The central regions of cool-core galaxy clusters harbour multiphase gas, with gas temperatures ranging from --. Feedback from active galactic nuc…
Characterising the turbulent multiphase halos with periodic box simulations
Rajsekhar Mohapatra, Mrinal Jetti, Prateek Sharma +1
Turbulence in the intracluster medium (ICM) is driven by active galactic nuclei (AGNs) jets, by mergers, and in the wakes of infalling galaxies. It not only governs gas motion but…
Turbulent density and pressure fluctuations in the stratified intracluster medium
Rajsekhar Mohapatra, Christoph Federrath, Prateek Sharma
Turbulent gas motions are observed in the intracluster medium (ICM). The ICM is density-stratified, with the gas density being highest at the centre of the cluster and decreasing r…
Turbulence in stratified atmospheres: implications for the intracluster medium
Rajsekhar Mohapatra, Christoph Federrath, Prateek Sharma
The gas motions in the intracluster medium (ICM) are governed by stratified turbulence. Stratified turbulence is fundamentally different from Kolmogorov (isotropic, homogeneous) tu…
Turbulence in the intracluster medium: simulations, observables & thermodynamics
Rajsekhar Mohapatra, Prateek Sharma
We conduct two kinds of homogeneous isotropic turbulence simulations relevant for the intracluster medium (ICM): (i) pure turbulence runs without radiative cooling; (ii) turbulent…
