Elusives/Invisibles+ Webinar: Gravitational Waves as a New Probe of Dark Matter
Specialist level
Speaker:
Dr. Bhupal Dev
Institution:
Washington U., St. Louis
Location&Place:
Audiovisual Room
Abstract:
Dear everyone,
We encourage you to follow the discussion of the Invisibles+ and Elusives webinar through the group connection at the Sala de Audiovisuales of the IFT (ground floor) at 15:00.
See the details bellow.
Cheers,

A dark matter (DM) halo intervening along the line of sight of a gravitational wave (GW) signal could induce a change in the speed of GW. We show that this change of speed is observable with the current LIGO sensitivity for a class of ultralight DM models which could form a Bose-Einstein condensate (BEC) in the early universe and behave as a single coherent wave instead of individual particles in galaxies. Hence, we propose to use the deviation in the speed of GW as a new probe of the BEC DM parameter space. With a multi-messenger approach to GW astronomy and/or with extended sensitivity to lower GW frequencies, the entire BEC DM parameter space can be effectively probed by our new method in the near future.
