The cosmic web in Lyman-alpha emission
Chris Byrohl, Dylan Nelson
We develop a comprehensive theoretical model for Lyman-alpha emission, from the scale of individual Lyman-alpha emitters (LAEs) to Lyman-alpha halos (LAHs), Lyman-alpha blobs (LABs…
Emission-line properties of IllustrisTNG galaxies: from local diagnostic diagrams to high-redshift predictions for JWST
Michaela Hirschmann, Stephane Charlot, Anna Feltre +8
We compute synthetic, rest-frame optical and ultraviolet (UV) emission-line properties of galaxy populations at redshifts from z0 to z=8 in a full cosmological framework.…
MUSE-ALMA Haloes VIII: Statistical Study of Circumgalactic Medium Gas
Simon Weng, Céline Péroux, Arjun Karki +15
The distribution of gas and metals in the circumgalactic medium (CGM) plays a critical role in how galaxies evolve. The MUSE-ALMA Halos survey combines MUSE, ALMA and HST observati…
MUSE-ALMA Haloes VII: Survey Science Goals & Design, Data Processing and Final Catalogues
Céline Péroux, Simon Weng, Arjun Karki +16
The gas cycling in the circumgalactic regions of galaxies is known to be multi-phase. The MUSE-ALMA Haloes survey gathers a large multi-wavelength observational sample of absorptio…
Feedback reshapes the baryon distribution within haloes, in halo outskirts, and beyond: the closure radius from dwarfs to massive clusters
Mohammadreza Ayromlou, Dylan Nelson, Annalisa Pillepich
We explore three sets of cosmological hydrodynamical simulations, IllustrisTNG, EAGLE, and SIMBA, to investigate the physical processes impacting the distribution of baryons in and…
The Circumgalactic Medium of Milky Way-like Galaxies in the TNG50 Simulation -- I: Halo Gas Properties and the Role of SMBH Feedback
Rahul Ramesh, Dylan Nelson, Annalisa Pillepich
We analyze the physical properties of gas in the circumgalactic medium (CGM) of 132 Milky Way (MW)-like central galaxies at from the cosmological magneto-hydrodynamical simul…
Satellites of Milky Way- and M31-like galaxies with TNG50: quenched fractions, gas content, and star formation histories
Christoph Engler, Annalisa Pillepich, Gandhali D. Joshi +3
We analyse the quenched fractions, gas content, and star formation histories of ~1200 satellite galaxies with around 198 Milky Way- (MW) and…
The merger and assembly histories of Milky Way- and M31-like galaxies with TNG50: disk survival through mergers
Diego Sotillo-Ramos, Annalisa Pillepich, Martina Donnari +6
We analyze the merger and assembly histories of Milky Way (MW) and Andromeda (M31)-like galaxies to quantify how, and how often, disk galaxies of this mass can survive recent major…
Modeling globular clusters in the TNG50 simulation: predictions from dwarfs to giants
Jessica E. Doppel, Laura V. Sales, Dylan Nelson +9
We present a post-processing catalog of globular clusters (GCs) for the most massive groups and clusters in the TNG50 simulation of the IlllustrisTNG project (virial masses $M…
UV to submillimetre luminosity functions of TNG50 galaxies
Ana Trcka, Maarten Baes, Peter Camps +7
We apply the radiative transfer (RT) code SKIRT on a sample of ~14000 low-redshift (z<= 0.1) galaxies extracted from the TNG50 simulation to enable an apples-to-apples comparison w…
Expectations of the size evolution of massive galaxies at from the TNG50 simulation: the CEERS/JWST view
Luca Costantin, Pablo G. Pérez-González, Jesús Vega-Ferrero +16
We present a catalog of about 25,000 images of massive () galaxies at redshift from the TNG50 cosmological simulation, tailored for…
Ionizing photon production and escape fractions during cosmic reionization in the TNG50 simulation
Ivan Kostyuk, Dylan Nelson, Benedetta Ciardi +2
In this work we investigate the dependence of the escape fraction of ionizing photons, , on various galaxy and host halo properties during the epoch of reionization. W…
