A fast spectral-multigrid Poisson solver in non-Cartesian geometries
Ankush Mandal, Oliver Gressel, Udo Ziegler +1
Accurate and efficient computation of self-gravity is essential in astrophysical fluid dynamics, particularly in spherical and cylindrical geometries where large radial dynamic ran…
Investigating field burial by magnetically confined accretion mounds on Neutron Stars
Saurabh Yeole, Dipanjan Mukherjee, Ankush Mandal
We explore the problem of magnetic confinement of accreted matter forming an accretion mound near the magnetic poles of a neutron star. We calculate the magnetic field geometry of…
Probing the role of self-gravity in clouds impacted by AGN-driven winds
Ankush Mandal, Dipanjan Mukherjee, Christoph Federrath +3
The impact of winds and jet-inflated bubbles driven by active galactic nuclei (AGN) are believed to significantly affect the host galaxy's interstellar medium (ISM) and regulate st…
A self-gravity module for the PLUTO code
Ankush Mandal, Dipanjan Mukherjee, Andrea Mignone
We present a novel implementation of an iterative solver for the solution of the Poisson equation in the PLUTO code for astrophysical fluid dynamics. Our solver relies on a relaxat…
Modelling observable signatures of jet-ISM interaction: thermal emission and gas kinematics
Moun Meenakshi, Dipanjan Mukherjee, Alexander Y. Wagner +6
Relativistic jets are believed to have a substantial impact on the gas dynamics and evolution of the interstellar medium (ISM) of their host galaxies. In this paper, we aim to draw…
Impact of relativistic jets on the star formation rate: a turbulence-regulated framework
Ankush Mandal, Dipanjan Mukherjee, Christoph Federrath +4
We apply a turbulence-regulated model of star formation to calculate the star formation rate (SFR) of dense star-forming clouds in simulations of jet-ISM interactions. The method i…
Jet-driven AGN feedback on molecular gas and low star-formation efficiency in a massive local spiral galaxy with bright X-ray halo
N. P. H. Nesvadba, A. Y. Wagner, D. Mukherjee +6
It has long been suspected that powerful radio sources may lower the efficiency with which stars form from the molecular gas in their host galaxy, but so far, alternative mechanism…
One-point probability distribution function from spherical collapse: Early Dark Energy (EDE) vs. CDM
Ankush Mandal, Sharvari Nadkarni-Ghosh
We compute the one-point PDF of an initially Gaussian dark matter density field using spherical collapse (SC). We compare the results to other forms available in the literature and…
Molecular cloud formation by compression of magnetized turbulent gas subjected to radiative cooling
Ankush Mandal, Christoph Federrath, Bastian Körtgen
Complex turbulent motions of magnetized gas are ubiquitous in the interstellar medium. The source of this turbulence, however, is still poorly understood. Previous work suggests th…
