The Cosmological Evolution of Light Dark Photon Dark Matter
Samuel D. McDermott, Samuel J. Witte
Light dark photons are subject to various plasma effects, such as Debye screening and resonant oscillations, which can lead to a more complex cosmological evolution than is experie…
Implications of BBN Bounds for Cosmic Ray Upscattered Dark Matter
Gordan Krnjaic, Samuel D. McDermott
We consider the Big Bang Nucleosynthesis (BBN) bounds on light dark matter whose cross section off nucleons is sufficiently large to enable acceleration by scattering off of cosmic…
Dark Radiation and Superheavy Dark Matter from Black Hole Domination
Dan Hooper, Gordan Krnjaic, Samuel D. McDermott
If even a relatively small number of black holes were created in the early universe, they will constitute an increasingly large fraction of the total energy density as space expand…
Constraining the Self-Interacting Neutrino Interpretation of the Hubble Tension
Nikita Blinov, Kevin J. Kelly, Gordan Krnjaic +1
Large, non-standard neutrino self-interactions have been shown to resolve the tension in Hubble constant measurements and a milder tension in the amplitude of matter fluc…
Cosmological Probes of Dark Matter Interactions: The Next Decade
Vera Gluscevic, Yacine Ali-Haimoud, Keith Bechtol +16
Cosmological observations offer unique and robust avenues for probing the fundamental nature of dark matter particles-they broadly test a range of compelling theoretical scenarios,…
Dark Matter Science in the Era of LSST
Keith Bechtol, Alex Drlica-Wagner, Kevork N. Abazajian +177
Astrophysical observations currently provide the only robust, empirical measurements of dark matter. In the coming decade, astrophysical observations will guide other experimental…
