Globular cluster distributions as a dynamical probe of dark matter
Nativ Ben-Yeda, Kfir Blum, Inbar Havilio
Globular clusters (GCs) act as massive probe particles traversing the dark matter halos of their host galaxies. Gravitational dynamical friction due to halo particles causes GC orb…
Ultra-Light Dark Matter Simulations and Stellar Dynamics: Tension in Dwarf Galaxies for eV
Luca Teodori, Andrea Caputo, Kfir Blum
We present numerical simulations of dark matter and stellar dynamics in ultra light dark matter halos tailored to mimic dwarf galaxies. An important effect we observe is the dynami…
Dynamical friction in globular cluster-rich ultra-diffuse galaxies: the case of NGC5846-UDG1
Nitsan Bar, Shany Danieli, Kfir Blum
Ultra-diffuse galaxies that contain a large sample of globular clusters (GCs) offer an opportunity to test the predictions of galactic dynamics theory. NGC5846-UDG1 is an excellent…
Assessing the Fornax globular cluster timing problem in different models of dark matter
Nitsan Bar, Diego Blas, Kfir Blum +1
We investigate what the orbits of globular clusters (GCs) in the Fornax dwarf spheroidal (dSph) galaxy can teach us about dark matter (DM). This problem was recently studied for ul…
