MEGATRON: the impact of non-equilibrium effects and local radiation fields on the circumgalactic medium at cosmic noon

Corentin Cadiou, Harley Katz, Martin P. Rey +22

We present three cosmological radiation-hydrodynamic zoom simulations of the progenitor of a Milky Way-mass galaxy from the MEGATRON suite. The simulations combine on-the-fly radia…

MEGATRON: Reproducing the Diversity of High-Redshift Galaxy Spectra with Cosmological Radiation Hydrodynamics Simulations

Harley Katz, Martin P. Rey, Corentin Cadiou +21

We present the MEGATRON suite of cosmological radiation hydrodynamics simulations following the formation of Milky Way-mass galaxies from the earliest cosmic epochs when Population…

MEGATRON: Disentangling Physical Processes and Observational Bias in the Multi-Phase ISM of High-Redshift Galaxies

Nicholas Choustikov, Harley Katz, Alex J. Cameron +10

Now detected out to redshifts of , the rest-frame ultraviolet and optical spectra of galaxies encode numerous physical properties of the interstellar medium (ISM). Accu…

MEGATRON: how the first stars can create an iron metallicity plateau in the smallest dwarf galaxies

Martin P. Rey, Harley Katz, Corentin Cadiou +23

We study the stellar mass-iron metallicity relation of dwarf galaxies in the new high-resolution MEGATRON cosmological radiation-hydrodynamics simulations. These simulations model…

A Momentum-Resolved X-ray Thomson Scattering Benchmark of Electronic-Response Models in Warm Dense Aluminium

Dmitrii S. Bespalov, Ulf Zastrau, Zhandos A. Moldabekov +58

The robust diagnosis of conditions generated in warm dense matter (WDM) experiments remains a persistent challenge. Here we describe the measurement of shock-compressed aluminium a…

Plasma density profile reconstruction of a gas cell for Ionization Induced Laser Wakefield Acceleration

F. Filippi, L. T. Dickson, M. Backhouse +15

Laser-driven plasma wakefields can provide hundreds of MeV electron beam in mm-range distances potentially shrinking the dimension of the actual particle accelerators. The plasma d…
