Calorimetric Dark Matter Detection with Galactic Center Gas Clouds.

Summary of "Calorimetric Dark Matter Detection with Galactic Center Gas Clouds."

We demonstrate that dark matter heating of gas clouds, hundreds of parsecs from the Milky Way Galactic Center, provides a powerful new test of dark matter interactions. To illustrate, we set a new bound on nucleon scattering for 10-100 MeV mass dark matter. We also constrain millicharged dark matter models, including those proposed to match the recent EDGES 21 cm absorption anomaly. For Galactic Center gas clouds, the Galactic fields' magnetic deflection of electromagnetically charged dark matter is mitigated, because the magnetic fields around the Galactic Center are poloidal, as opposed to being aligned parallel to the Milky Way disk. We discuss prospects for detecting dark matter using a population of Galactic Center gas clouds warmed by dark matter.

To compare the detection performance of near-, mid-, and far-infrared laser fuzes in clouds, we built a laser fuze detection model in a cloud environment based on the Monte Carlo method, and simulated...

Constraining a Thin Dark Matter Disk with Gaia.

If a component of the dark matter has dissipative interactions, it could collapse to form a thin dark disk in our Galaxy that is coplanar with the baryonic disk. It has been suggested that dark disks ...
