Evaluating the flexibility of the MillenniumTNG galaxy formation model with multi-zoom re-simulations
Francisco Maion, Raul E. Angulo, Volker Springel +2
The authors develop a multi-zoom simulation suite based on the MillenniumTNG run to test how star‑formation and AGN feedback parameters affect the galaxy stellar‑mass function and…
Learning the Universe with cosmological rescaling of merger trees and semi-analytic galaxy formation models
Richard Stiskalek, Lucia A. Perez, Shy Genel +3
Learning cosmology from galaxy surveys requires large suites of simulations spanning the cosmological and astrophysical parameter space, yet hydrodynamical simulations of galaxy fo…
Learning the Universe with the 2nd Generation of CAMELS: Varying 35 parameters of the IllustrisTNG model in (50Mpc/h)^3 boxes
Shy Genel, Yongseok Jo, Boon Kiat Oh +10
We present a new set of 1,192 cosmological simulations as part of the CAMELS project, in which a space of 35 cosmological, astrophysical, and numerical parameters is explored aroun…
The Thermodynamic and Kinematic Evolution of Circumgalactic Gas around in the IllustrisTNG model
Daniel DeFelippis, Shy Genel, Greg L. Bryan
The circumgalactic medium (CGM) is known to contain multiphase gas in various stages of evolution and interaction with the galaxy. In order to characterize its detailed behavior on…
Efficiently emulating distribution functions in gigaparsec volumes for varying cosmological parameters
Christopher C. Lovell, Max E. Lee, William J. Roper +4
We present a new method for emulating the halo mass function (HMF) and other distribution functions in large effective volumes, down to low halo masses, whilst simultaneously modif…
The impact of baryons on weak lensing statistics as a function of halo mass and radius
Max E. Lee, Zoltan Haiman, Shy Genel
Upcoming weak lensing (WL) surveys such as those by {\it Euclid}, LSST, and {\it Roman} require percent-level control over systematic effects. A common approach to mitigating baryo…
