Collisional Dynamics of Stars and Dark Matter in Ultra-Faint Galaxies
Raphaël Errani, Nicolas Esser, Jorge Peñarrubia +1
We use controlled N-body simulations to study the collisional exchange of energy between stars and dark matter in ultra-faint galaxies. We find that dynamical friction between star…

Dark matter dynamical friction on binary stars in the faintest dwarf galaxies: I. Analytical approach
Nicolas Esser
We study binary stars moving through a uniform dark matter background and experiencing dynamical friction. The centre-of-mass motion of the pairs is taken into account. We derive f…

Gravitational waves from primordial black holes passing by neutron stars: observational prospects for the Galactic center
Nicolas Esser, Juan García-Bellido, Peter Tinyakov
We investigate the gravitational wave (GW) signals emitted by planetary-mass primordial black holes (PBHs) passing nearby or traversing neutron stars (NSs). While previous studies…
