Query: Point Sources from Dissipative Dark Matter   If a component of dark matter has dissipative interactions, it can cool to
form compact astrophysical objects with higher density than that of
conventional cold dark matter (sub)haloes. Dark matter annihilations might then
appear as point sources, leading to novel morphology for indirect detection. We
explore dissipative models where interaction with the Standard Model might
provide visible signals, and show how such objects might give rise to the
observed excess in gamma rays arising from the galactic center.
