The Galactic Squeeze: How Aggregate and Highly Dynamical Environments Shape Star Formation in the Local Universe

Wesley Van Kempen, Michelle E. Cluver, Edward N. Taylor +2

We investigate how galaxy evolution varies with environment in the nearby Universe by comparing an ``average'' reference volume in the Southern Galactic Pole (SGP) dataset from \ci…

Group Therapy for Halos: Advancing Halo Mass Estimation for Galaxy Groups

Welsey Van Kempen, Michelle E. Cluver, Edward N. Taylor +3

Accurate estimation of dark matter halo masses for galaxy groups is central to studies of galaxy evolution and for leveraging group catalogues as cosmological probes. We present a…

Tidal adaptive softening and artificial fragmentation in cosmological simulations

Robert A. Mostoghiu Paun, Darren Croton, Chris Power +3

Traditional N-body methods introduce localised perturbations in the gravitational forces governing their evolution. These perturbations lead to an artificial fragmentation in the f…

The Cosmic Evolution Early Release Science Survey (CEERS)

Steven L. Finkelstein, Micaela B. Bagley, Pablo Arrabal Haro +96

We present the Cosmic Evolution Early Release Science (CEERS) Survey, a 77.2 hour Director's Discretionary Early Release Science Program. CEERS demonstrates, tests, and validates e…

Using dust to constrain dark matter models

Adam Ussing, Robert Mostoghiu Paun, Darren Croton +3

In this paper, we use hydrodynamic zoom-in simulations of Milky Way-type haloes to explore using dust as an observational tracer to discriminate between cold and warm dark matter (…

A Comprehensive Investigation of Environmental Influences on Galaxies in Group Environments

W. Van Kempen, M. E. Cluver, T. H. Jarrett +6

Environment has long been known to impact the evolution of galaxies, but disentangling its effects from mass evolution requires careful analysis of statistically significant sample…
