Globular clusters as probes of dark matter cusp-core transformations
M. D. A. Orkney, J. I. Read, James A. Petts +1
Bursty star formation in dwarf galaxies can slowly transform a steep dark matter cusp into a constant density core. We explore the possibility that globular clusters (GCs) retain a…
Probing dark matter with star clusters: a dark matter core in the ultra-faint dwarf Eridanus II
Filippo Contenta, Eduardo Balbinot, James A. Petts +6
We present a new technique to probe the central dark matter (DM) density profile of galaxies that harnesses both the survival and observed properties of star clusters. As a first a…
Infalling Young Clusters in the Galactic Centre: implications for IMBHs and young stellar populations
J. A. Petts, A. Gualandris
The central parsec of the Milky Way hosts two puzzlingly young stellar populations, a tight isotropic distribution of B stars around SgrA* (the S-stars) and a disk of OB stars exte…
A semi-analytic dynamical friction model for cored galaxies
James A. Petts, Justin I. Read, Alessia Gualandris
We present a dynamical friction model based on Chandrasekhar's formula that reproduces the fast inspiral and stalling experienced by satellites orbiting galaxies with a large const…
A Semi-Analytic dynamical friction model that reproduces core stalling
James A. Petts, Alessia Gualandris, Justin I. Read
We present a new semi-analytic model for dynamical friction based on Chandrasekhar's formalism. The key novelty is the introduction of physically motivated, radially varying, maxim…
