Conservation of radial actions in time-dependent spherical potentials
Jan D. Burger, Jorge Peñarrubia, Jesús Zavala
In slowly evolving spherical potentials, , radial actions are typically assumed to remain constant. Here, we construct dynamical invariants that allow us to derive the evol…
ETHOS -- An Effective Theory of Structure Formation: Impact of Dark Acoustic Oscillations on Cosmic Dawn
Julian B. Muñoz, Sebastian Bohr, Francis-Yan Cyr-Racine +2
Upcoming data of the 21-cm hydrogen line during cosmic dawn () will revolutionize our understanding of the astrophysics of the first galaxies. Here we present a case s…
The impact of inelastic self-interacting dark matter on the dark matter structure of a Milky Way halo
Kun Ting Eddie Chua, Karia Dibert, Mark Vogelsberger +1
We study the effects of inelastic dark matter self-interactions on the internal structure of a simulated Milky Way (MW)-size halo. Self-interacting dark matter (SIDM) is an alterna…
The Onset of Gravothermal Core Collapse in Velocity Dependent Self-Interacting Dark Matter Subhaloes
Hannah C. Turner, Mark R. Lovell, Jesús Zavala +1
It has been proposed that gravothermal collapse due to dark matter self-interactions (i.e. self-interacting dark matter, SIDM) can explain the observed diversity of the Milky Way (…
Simulating the "hidden giant" in cold and self-interacting dark matter models
Omid Sameie, Sukanya Chakrabarti, Hai-Bo Yu +4
We perform a series of controlled N-body simulations to study realizations of the recently discovered Antlia 2 galaxy in cold dark matter (CDM) and self-interacting dark matter (SI…
ETHOS -- An effective parametrization and classification for structure formation: the non-linear regime at
Sebastian Bohr, Jesús Zavala, Francis-Yan Cyr-Racine +3
We propose two effective parameters that fully characterise galactic-scale structure formation at high redshifts () for a variety of dark matter (DM) models that have a…
