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…
Woven by the Whirls: The growth and entrainment of cold clouds in turbulent hot winds
Ritali Ghosh, Max Gronke, Prateek Sharma +1
Galactic and intergalactic flows often exhibit relative motion between the cold dense gas and the hot diffuse medium. Such multiphase flows -- involving gas at different temperatur…
Fading in the Flow: Suppression of cold gas growth in expanding galactic outflows
Alankar Dutta, Prateek Sharma, Max Gronke
Multiphase outflows, revealed by multi-wavelength observations, are crucial in redistributing gas and metals within and around galaxies. These outflows are often modelled theoretic…
Misty, patchy, and turbulent: constraining the cool circumgalactic medium with mCC
Mukesh Singh Bisht, Prateek Sharma, Alankar Dutta +1
The circumgalactic medium (CGM) is the largest baryon reservoir around galaxies, but its extent, mass, and temperature distribution remain uncertain. We propose that cool gas ($\si…
Ram pressure stripping in clusters: Gravity can bind the ISM but not the CGM
Ritali Ghosh, Alankar Dutta, Prateek Sharma
We explore the survival of a galaxy's circumgalactic medium (CGM) as it experiences ram pressure stripping (RPS) moving through the intracluster medium (ICM). For a satellite galax…
Beyond radial profiles: Using log-normal distributions to model the multiphase circumgalactic medium
Alankar Dutta, Mukesh Singh Bisht, Prateek Sharma +3
Recent observations and simulations reveal that the circumgalactic medium (CGM) surrounding galaxies is multiphase, with the gas temperatures spanning a wide range at most radii, $…
Cooling flows around cold clouds in the circumgalactic medium: steady-state models & comparison with TNG50
Alankar Dutta, Prateek Sharma, Dylan Nelson
Cold, non-self-gravitating clumps occur in various astrophysical systems, ranging from the interstellar and circumgalactic medium (CGM), to AGN outflows and solar coronal loops. Co…
Growth and structure of multiphase gas in the cloud-crushing problem with cooling
Vijit Kanjilal, Alankar Dutta, Prateek Sharma
We revisit the problem of the growth of dense/cold gas in the cloud-crushing setup with radiative cooling. The relative motion between the dense cloud and the diffuse medium produc…
On modelling CC85 wind in an expanding local box
Alankar Dutta, Prateek Sharma
The Chevalier & Clegg (1985) spherical wind is widely used to model galactic outflows. Efforts are underway to understand the production of multiphase gas in such outflows. Since t…
Mean Occupation Function of High Redshift Quasars from the Planck Cluster Catalog
Priyanka Chakraborty, Suchetana Chatterjee, Alankar Dutta +1
We characterise the distribution of quasars within dark matter halos using a direct measurement technique for the first time at redshifts as high as . Using the Planck Su…
