G01.00001: The Search for Dark Matter: A Particle Theory Perspective Invited Speaker: Asimina Arvanitaki The existence of Dark Matter is the most compelling evidence we have for physics beyond the Standard Model. In this talk, I will review some well-motivated theoretical ideas for the origin of Dark Matter and the novel ways they can be experimentally tested. [Preview Abstract] |

G01.00002: Gravitational Probes of Dark Matter Invited Speaker: Alex Drlica-Wagner Dark matter makes up 25\% of the matter--energy density of the Universe but is not composed of any particle known to the Standard Model. To date, the only robust empirical evidence for the existence of dark matter comes from astrophysical and cosmological observations. These observations can probe the fundamental nature of dark matter through gravity, the only force to which dark matter is known to couple. I will discuss some recent advances in the study of dark matter with large cosmic survey experiments. [Preview Abstract] |

G01.00003: Astrophysical Probes of Dark Matter Invited Speaker: Ana Bonaca Orbits of individual stars in the Milky Way trace the underlying gravitational potential, and as such, they provide a unique insight into the distribution of matter in our galaxy. Large astronomical projects like Gaia, SDSS and DESI are now measuring precise motions of stars deep into the dark matter-dominated outer regions of our galaxy. I will discuss how these measurements allow us to precisely reconstruct the 3D distribution of dark matter throughout the galaxy, and for the first time, open the possibility of identifying individual dark-matter substructures.
