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…
