Mixed Dark Matter: Limits from the Milky Way Satellite Galaxies
Wendy Crumrine, Dominic Pang, Ethan O. Nadler +2
The Standard Model of particle physics contains a diverse set of particle species, motivating the possibility of a similarly complex dark sector. Here we study two-component dark m…
A graph-based Neural Network surrogate model for accelerating semi-analytical model of galaxy formation and evolution
Xuejie Li, Zhongxu Zhai, Xiaohu Yang +2
Understanding how galaxy populations emerge and evolve from the growth of dark matter structure is a central challenge in galaxy formation theory. Semi-analytic models (SAMs) provi…
Warm, not Fuzzy: Generalized Ultralight Dark Matter Limits from Milky Way Satellites
Ethan O. Nadler, Mustafa A. Amin, Risa H. Wechsler +3
We generalize lower limits on the dark matter (DM) particle mass derived from Milky Way (MW) satellite galaxy abundances to scenarios in which DM is an ultralight scalar field…
The THESAN project: environmental drivers of Local Group reionization
Yu Zhao, Aaron Smith, Rahul Kannan +5
The timing of cosmic reionization across Local Group (LG) analogues provides insights into their early histories and surrounding large-scale structure. Using the radiation-hydrodyn…
The Effects of Linear Matter Power Spectrum Enhancement on Dark Matter Substructure
Ethan O. Nadler, Vera Gluscevic, Andrew Benson
We present cosmological dark matter (DM)--only zoom-in simulations of a Milky Way analog originating from enhanced linear matter power spectra relative to the standard cold,…
Novel Challenges in Tracking Self-Interacting Dark Matter Subhalos
Demao Kong, Hai-Bo Yu, Ethan O. Nadler +2
Cosmological N-body simulations are among the primary tools for studying structure formation in the Universe. Analyses of these simulations critically depend on accurately identify…
Semianalytic model for decaying dark matter halos
Ethan O. Nadler, Andrew J. Benson
Decaying dark matter (DDM) affects the evolution of cosmic structure relative to standard cold, collisionless, stable dark matter (CDM). We introduce a new semianalytic model for t…
COZMIC. III. Cosmological Zoom-in Simulations of Self-interacting Dark Matter with Suppressed Initial Conditions
Ethan O. Nadler, Rui An, Daneng Yang +3
We present eight cosmological dark matter (DM)--only zoom-in simulations of a Milky Way--like system that include suppression of the linear matter power spectrum , and/or vel…
COZMIC. II. Cosmological Zoom-in Simulations with Fractional non-CDM Initial Conditions
Rui An, Ethan O. Nadler, Andrew Benson +1
We present cosmological dark matter (DM)-only zoom-in simulations of a Milky Way analog with initial conditions appropriate for scenarios where non-cold dark matter (NCDM) is…
Population synthesis and astrophysical inference for high- JWST galaxies
Trey Driskell, Ethan O. Nadler, Andrew Benson +1
Observations of the high- Universe from JWST have revealed a new population of bright, early galaxies. A robust statistical interpretation of this data requires fast forward mod…
COZMIC. I. Cosmological Zoom-in Simulations with Initial Conditions Beyond Cold Dark Matter
Ethan O. Nadler, Rui An, Vera Gluscevic +2
We present 72 cosmological dark matter-only -body zoom-in simulations with initial conditions beyond cold, collisionless dark matter (CDM), as the first installment of the COZMI…
