MOSEL survey: JWST reveals major mergers/strong interactions drive the extreme emission lines in the early universe
Anshu Gupta, Ravi Jaiswar, Vicente Rodriguez-Gomez +7
Extreme emission line galaxies (EELGs), where nebular emissions contribute 30-40% of the flux in certain photometric bands, are ubiquitous in the early universe (z>6). We utilise d…
ERGO-ML: Comparing IllustrisTNG and HSC galaxy images via contrastive learning
Lukas Eisert, Connor Bottrell, Annalisa Pillepich +5
Modern cosmological hydrodynamical galaxy simulations provide tens of thousands of reasonably realistic synthetic galaxies across cosmic time. However, quantitatively assessing the…
A physically motivated framework to compare pair fractions of isolated low and high mass galaxies across cosmic time
Katie Chamberlain, Gurtina Besla, Ekta Patel +9
Low mass galaxy pair fractions are understudied, and it is unclear whether low mass pair fractions evolve in the same way as more massive systems over cosmic time. In the era of JW…
The progenitors of the intra-cluster light and intra-cluster globular clusters in galaxy groups and clusters
Niusha Ahvazi, Laura V. Sales, Jessica E. Doppel +3
We use the IllustrisTNG50 cosmological hydrodynamical simulation, complemented by a catalog of tagged globular clusters, to investigate the properties and build up of two extended…
Negligible Effects of Baryons on the Angular Momentum Scaling Relations of Galactic Dark Matter Halos
S. Michael Fall, Vicente Rodriguez-Gomez
In cosmological simulations without baryons, the relation between the specific angular momentum and mass of galactic dark matter halos has the well-establis…
Milky Way and Andromeda analogs from the TNG50 simulation
Annalisa Pillepich, Diego Sotillo-Ramos, Rahul Ramesh +7
We present the properties of Milky Way- and Andromeda-like (MW/M31-like) galaxies simulated within TNG50, the highest-resolution run of the IllustrisTNG suite of CDM magneto-hyd…
The growth of brightest cluster galaxies in the TNG300 simulation:dissecting the contributions from mergers and in situ star formation
Daniel Montenegro-Taborda, Vicente Rodriguez-Gomez, Annalisa Pillepich +4
We investigate the formation of brightest cluster galaxies (BCGs) in the TNG300 cosmological simulation of the IllustrisTNG project. Our cluster sample consists of 700 haloes with…
