The Local Group on FIRE: dwarf galaxy populations across a suite of hydrodynamic simulations [PDF]

Monthly notices of the Royal Astronomical Society, 2018
We present a new set of high-resolution hydrodynamic cosmological zoom-in simulations that apply the Feedback In Realistic Environments physics to both Local Group (LG)-like and isolated Milky Way (MW)-like volumes (10 host systems in total with a ...

General-relativistic Radiation Transport Scheme in Gmunu. I. Implementation of Two-moment-based Multifrequency Radiative Transfer and Code Tests

The Astrophysical Journal Supplement Series, 2023
We present the implementation of a two-moment-based general-relativistic multigroup radiation transport module in the G eneral-relativistic mu ltigrid nu merical ( Gmunu ) code.

Modelling Dust Evolution in Galaxies with a Multiphase, Inhomogeneous ISM [PDF]

, 2016
We develop a model of dust evolution in a multiphase, inhomogeneous ISM including dust growth and destruction processes. The physical conditions for grain evolution are taken from hydrodynamical simulations of giant molecular clouds in a Milky Way-like ...

CMR Exploration. I. Filament Structure with Synthetic Observations

The Astrophysical Journal Supplement Series, 2023
In this paper, we carry out a pilot parameter exploration for the collision-induced magnetic reconnection (CMR) mechanism that forms filamentary molecular clouds.

The Many Routes to AGN Feedback [PDF]

, 2017
The energy released by Active Galactic Nuclei (AGN) in the form of radiation, winds, or radio plasma jets, is known to impact on the surrounding interstellar medium. The result of these processes, known as AGN (negative) feedback, is suggested to prevent

Astronomical Seeing and Turbulence Profile Simulations over Complex Terrain at the Thai National Observatory Using a Chemistry-Coupled Regional Forecasting Model

Monthly notices of the Royal Astronomical Society
This study utilized advanced numerical simulations with the Weather Research and Forecasting model coupled with Chemistry (WRF-Chem) to predict anticipated astronomical seeing conditions at the Thai National Observatory (TNO).

The origins of the circumgalactic medium in the FIRE simulations [PDF]

Monthly notices of the Royal Astronomical Society, 2018
We use a particle tracking analysis to study the origins of the circumgalactic medium (CGM), separating it into (1) accretion from the intergalactic medium (IGM), (2) wind from the central galaxy, and (3) gas ejected from other galaxies.

On the theory of astronomical maser. I. Statistics of maser radiation

, 2009
In this paper we re-analyse the amplification process of broadband continuum radiation by astronomical masers in one-dimensional case. The basic equations appropriate for the scalar maser and the random nature of the maser radiation field are derived ...

Two-temperature, Magnetically Arrested Disc simulations of the jet from the supermassive black hole in M87 [PDF]

Monthly notices of the Royal Astronomical Society, 2018
We present two-temperature, radiative general relativistic magnetohydrodynamic simulations of Magnetically Arrested Discs (MAD) that launch powerful relativistic jets.
