Influence of tides and self-gravity on ultralight dark matter bounds from dwarf galaxies

Author(s): Andrea Caputo and Luca TeodoriDwarf spheroidal galaxies provide some of the most sensitive astrophysical probes of ultralight dark matter (ULDM), but the inferred constraints can be affected by two important systematics: tidal interactions with the Milky Way, which reduce ULDM-induced dynamical heating, and stellar self-gravity,…[Phys.
