Dust in Galaxies at : Attenuation and Re-emission Predictions from the FirstLight Simulations
Yurina Nakazato, Akio K. Inoue, Rachel S. Somerville +3
Dust masses and grain properties in galaxies remain poorly constrained, as JWST UV attenuation and ALMA dust re-emission are rarely modelled consistently. We perform post-pr…
MEGATRON: The Physical Origins of Steep UV Slopes at High Redshift
Harley Katz, Nicholas Choustikov, Aayush Saxena +7
The ultraviolet (UV) spectral slope, , serves as a fundamental probe of stellar population properties and interstellar medium conditions in galaxies. At high redshift, a small s…
The TNG50-SKIRT Atlas: Spatially resolved synthetic galaxies from the ultraviolet to the submillimetre (DR2)
Maarten Baes, Paul Vauterin, Abdurro'uf +20
We present the second data release (DR2) of the TNG50-SKIRT Atlas (TSA), a library of synthetic, spatially resolved galaxy observables. The atlas is constructed by post-processing…
GREX-PLUS Science Book v2
PLUS Science Team, Shunsuke Baba, Sirio Belli +52
GREX-PLUS (Galaxy Reionization EXplorer and PLanetary Universe Spectrometer) is a mission candidate for a JAXA strategic L-class mission to be launched in the 2030s. Its primary sc…
Predicting ionised gas emission in 3D with SKIRT. I. Framework and validation
Anand Utsav Kapoor, Maarten Baes, Aaron Smith +7
Emission lines from ionised gas are key diagnostics of star formation, metallicity, and ionisation conditions in galaxies. Interpreting spatially resolved observations from integra…
Grain-size evolution and rapid dust growth in high-redshift galaxies
Daisuke Toyouchi, Andrea Ferrara, Yurina Nakazato +3
We present a galaxy evolution model that incorporates grain-size evolution in a multiphase interstellar medium (ISM) to investigate dust attenuation in galaxies at . Our…
Clump-Scale Dust Attenuation in Epoch of Reionization Galaxies: Spatially Resolved Properties from FirstLight Simulations
Yurina Nakazato, Kosei Matsumoto, Akio K. Inoue +3
Understanding dust attenuation in galaxies at both integrated and spatially resolved scales is fundamental for accurately determining the physical properties of galaxies. Recent hi…
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…
Diversity and Evolution of Dust Attenuation Curves from Redshift z ~ 1 to 9
Irene Shivaei, Rohan P. Naidu, Francisco Rodriguez Montero +23
The UV-optical dust attenuation curve is key to interpreting the intrinsic properties of galaxies and provides insights into the nature of dust grains and their geometry relative t…
Evolution of galaxy attenuation curves driven by evolving dust mass and grain size distributions
Kosei Matsumoto, Laura Sommovigo, Andrea Gebek +8
We investigate the impacts of the evolution of dust mass and grain size distribution within a Milky Way-like (MW-like) galaxy simulation on global attenuation curves, focusing on t…
The mass-dependent UVJ diagram at cosmic noon: A challenge for galaxy evolution models and dust radiative transfer
Andrea Gebek, Benedikt Diemer, Marco Martorano +9
Context. The UVJ color-color diagram is a widely used diagnostic to separate star-forming and quiescent galaxies. Observational data from photometric surveys reveal a strong stella…
Radial properties of dust in galaxies: Comparison between observations and isolated galaxy simulations
S. A. van der Giessen, K. Matsumoto, M. Relano +8
We study the importance of several processes that influence the evolution of dust and its grain size distribution on spatially resolved scales in nearby galaxies. Here, we compiled…
Observational signatures of the dust size evolution in isolated galaxy simulations

We aim to provide observational signatures of the dust size evolution in the ISM. In particular, we explore indicators of the polycyclic aromatic hydrocarbon (PAH) mass fraction ($…
Monte Carlo radiative transfer with explicit absorption to simulate absorption, scattering, and stimulated emission
Maarten Baes, Peter Camps, Kosei Matsumoto
Context: The Monte Carlo method is probably the most widely used approach to solve the radiative transfer problem, especially in a general 3D geometry. The physical processes of em…
