Magnetogenesis by galactic processes: impact on circumgalactic and intergalactic fields
Rahul Ramesh, Enrico Garaldi, Chris Byrohl
We investigate the origin and evolution of cosmic magnetic fields using a suite of large-volume cosmological magnetohydrodynamic simulations (L Mpc/h) run with th…
Zooming in on the circumgalactic medium with GIBLE: Cloud-scale simulations with cosmological initial conditions
Rahul Ramesh, Dylan Nelson, Drummond Fielding +1
We conduct simulations of kpc-scale cool clouds in the circumgalactic medium (CGM), using initial conditions sampled from a highly resolved cosmological magneto-hydrodynamica…
The Synthetic Absorption Line Spectral Almanac (SALSA)
Dylan Nelson, Celine Peroux, Philipp Richter +10
We create the first large-scale mock spectroscopic survey of gas absorption sightlines traversing the interstellar medium (ISM), circumgalactic medium (CGM), and intergalactic medi…
Numerical effects on the stripping of dark matter and stars in IllustrisTNG galaxy groups and clusters
Mark R. Lovell, Annalisa Pillepich, Christoph Engler +4
The stellar haloes and intra-cluster light around galaxies are crucial test beds for dark matter (DM) physics and galaxy formation models. We consider the role that the numerical r…
Tracing the cosmological origin of gas that fuels in situ star formation in TNG50 galaxies
Ole Wittig, Rahul Ramesh, Dylan Nelson
Based on their cosmological origin, the stars of a galaxy can be divided into two categories: those that enter through merger events (ex situ) and those born in the main progenitor…
IllustrisTNG + Cosmic Rays with a Simple Transport Model: From Dwarfs to L Galaxies
Rahul Ramesh, Dylan Nelson, Philipp Girichidis
We use a simple model for cosmic ray (CR) production and transport to assess the impact of CRs on \,\, galaxy, circumgalactic medium (CGM), and halo properties. To do so,…
Zooming in on the Circumgalactic Medium with GIBLE: Tracing the Origin and Evolution of Cold Clouds
Rahul Ramesh, Dylan Nelson, Drummond Fielding +1
We use the GIBLE suite of cosmological zoom-in simulations of Milky Way-like galaxies with additional super-Lagrangian refinement in the circumgalactic medium (CGM) to quantify the…
Zooming in on the Circumgalactic Medium with GIBLE: the Topology and Draping of Magnetic Fields around Cold Clouds
Rahul Ramesh, Dylan Nelson, Drummond Fielding +1
We use a cosmological zoom-in simulation of a Milky Way-like galaxy to study and quantify the topology of magnetic field lines around cold gas clouds in the circumgalactic medium (…
The physical origins of gas in the circumgalactic medium using observationally-motivated TNG50 mocks
Simon Weng, Celine Peroux, Rahul Ramesh +5
Absorbers in the spectrum of background objects probe the circumgalactic medium (CGM) surrounding galaxies, but its physical properties remain unconstrained. We use the cosmologica…
