A Self-gravity Module for the PLUTO Code

Autor: Ankush Mandal, Dipanjan Mukherjee, Andrea Mignone

Publikováno v: The Astrophysical Journal Supplement Series, Vol 268, Iss 1, p 40 (2023)

We present a novel implementation of an iterative solver for the solution of Poisson’s equation in the PLUTO code for astrophysical fluid dynamics. Our solver relies on a relaxation method in which convergence is sought as the steady-state solution

Modelling observable signatures of jet-ISM interactionkinematics

Autor: Moun Meenakshi, Dipanjan Mukherjee, Alexander Y Wagner, Nicole P H Nesvadba, Geoffrey V Bicknell, Raffaella Morganti, Reinier M J Janssen, Ralph S Sutherland, Ankush Mandal

Publikováno v: Monthly Notices of the Royal Astronomical Society, 516(1), 766-786. Oxford University Press

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 a link between the simulations and the observable signatures of jet-I

One-point probability distribution function from spherical collapse: early dark energy versus ΛCDM

Autor: Sharvari Nadkarni-Ghosh, Ankush Mandal

Publikováno v: Monthly Notices of the Royal Astronomical Society. 498:355-372

We compute the one-point probability distribution function (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 also compare the PDFs in the Λ-c

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 mechanisms, in particular related to the stellar mass distribution in the massi

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 isolates individual clumps and accounts for the impact of virial parame

Molecular cloud formation by compression of magnetized turbulent gas subjected to radiative cooling

Autor: Bastian Körtgen, Christoph Federrath, Ankush Mandal

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 that compression caused by supernova shockwaves, gravity, or cloud colli
