SUMMARY:Gravothermal evolution of galactic dark matter halos with velocity-
	dependent self-interactions
DESCRIPTION:Featuring Yiming Zhong\, Stony Brook\n\nPart of the HET Seminar
	 Series.\n\nThe evolution of galactic dark matter halos would be modified i
	f dark matter were self-interacting. The early heat conduction from the hal
	o envelope to the core would enlarge the core size and reduce the central c
	usps. The late heat conduction from the core to the envelope would collapse
	 the core into a singular state. Previous studies have focused on constrain
	ing the velocity independent self-interaction from the gravothermal evoluti
	on of the dark matter halo. In this talk\, we investigate the velocity depe
	ndent scenario\, which is well-motivated from low-mass dark sector models\,
	 and find the preferred and excluded interaction strengths based on two phy
	sical scenarios.
