ABSTRACT We apply a turbulence-regulated model of star formation to calculate the rate (SFR) dense star-forming clouds in simulations jet–interstellar medium (ISM) interactions. The method isolates individual clumps and accounts for impact virial parameter Mach number on activity. This improves upon other estimates SFR jet–ISM interactions, which are often solely based local gas density, neglecting turbulence. this framework results suite interaction study how jet regulates both globally...
Relativistic jets are believed to have a substantial impact on the gas dynamics and evolution of interstellar medium (ISM) their host galaxies. In this paper, we aim draw link between simulations observable signatures jet-ISM interactions by analyzing emission morphology kinematics resulting from jet-induced shocks in simulated disc spherical systems. We find that laterally expanding forward shock energy bubble sweeping through ISM causes large-scale outflows, creating shocked high-velocity...
It has long been suspected that powerful radio sources may lower the efficiency with which stars form from molecular gas in their host galaxy, but so far, alternative mechanisms, particular related to stellar mass distribution massive bulges of galaxies, are not ruled out. We present new ALMA CO(1-0) interferometry cold nearby (z=0.0755), (M_stellar=4x10^11 M_sun), isolated, late-type spiral galaxy 2MASSX J23453269-044925, is outstanding for having two pairs powerful, giant jets, and a...
Complex turbulent motions of magnetized gas are ubiquitous in the interstellar medium. The source this turbulence, however, is still poorly understood. Previous work suggests that compression caused by supernova shockwaves, gravity, or cloud collisions, may drive turbulence to some extent. In work, we present three-dimensional (3D) magnetohydrodynamic (MHD) simulations contraction turbulent, clouds from warm neutral medium (WNM) ISM formation cold dense molecular clouds, including radiative...
ABSTRACT 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) regulate star formation. To explore this scenario, we perform a suite hydrodynamic simulations model interaction between turbulent star-forming clouds highly pressurized AGN-driven outflows, focusing on effects self-gravity. Our results demonstrate that cloudlets fragmented wind can become gravitationally bound,...
We compute the one-point PDF of an initially Gaussian dark matter density field using spherical collapse (SC). compare results to other forms available in literature and also PDFs $Λ$CDM model with early energy (EDE) model. find that skewed log-normal distribution provides best fit non-linear from SC for both cosmologies, $a=0.1$ 1 scales characterized by comoving width Gaussian: $σ_G = 0.5, 1, 2$. To elucidate effect cosmology, we examine linear growth rates through test cases. For...
Abstract We present a novel implementation of an iterative solver for the solution Poisson’s equation in PLUTO code astrophysical fluid dynamics. Our relies on relaxation method which convergence is sought as steady-state parabolic equation, whose time discretization governed by Runge–Kutta–Legendre (RKL) method. findings indicate that RKL-based Poisson solver, both fully parallel and rapidly convergent, has potential to serve practical alternative conventional solvers such Gauss–Seidel...
