Real and counterfeit cores: how feedback expands halos and disrupts tracers of inner gravitational potential in dwarf galaxies
Ethan D. Jahn, Laura V. Sales, Federico Marinacci +8
The tension between the diverging density profiles in Lambda Cold Dark Matter (CDM) simulations and the constant-density inner regions of observed galaxies is a long-standing ch…
Degeneracies Between Self-interacting Dark Matter and Supernova Feedback as cusp-core transformation mechanisms
Jan D. Burger, Jesús Zavala, Laura V. Sales +3
We present a suite of 16 high-resolution hydrodynamic simulations of an isolated dwarf galaxy (gaseous and stellar disk plus a stellar bulge) within an initially cuspy dark matter…
SN-driven mechanism of cusp-core transformation: an appraisal
Jan D. Burger, Jesús Zavala
We present and test an effective model for N -body simulations that aims at mimicking the impact of supernova (SN) feedback on the dark matter (DM) distribution of isolated halos h…
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…
The nature of core formation in dark matter haloes: adiabatic or impulsive?
Jan D. Burger, Jesús Zavala
It is well established that the central deficit of dark matter (DM) observed in many dwarf galaxies disagrees with the cuspy DM haloes predicted in the collision-less and cold DM (…
A Study of Cosmic Ray Secondaries Induced by the Mir Space Station Using AMS-01
01 Collaboration
The Alpha Magnetic Spectrometer (AMS-02) is a high energy particle physics experiment that will study cosmic rays in the to range and will…
