First Star Formation in the Presence of Primordial Magnetic Fields

Kavli Affiliate: Tom Abel | First 5 Authors: Daegene Koh, Tom Abel, Karsten Jedamzik, , | Summary: It has been recently claimed that primordial magnetic fields could relieve the cosmological Hubble tension. We consider the impact of such fields on the formation of the first cosmological objects, mini-halos forming stars, for present-day field strengths in […]

Determining Dark Matter-Electron Scattering Rates from the Dielectric Function

Kavli Affiliate: Noah Kurinsky | First 5 Authors: Yonit Hochberg, Yonatan Kahn, Noah Kurinsky, Benjamin V. Lehmann, To Chin Yu | Summary: We show that the rate for dark matter-electron scattering in an arbitrary material is determined by an experimentally measurable quantity, the complex dielectric function, for any dark matter interaction that couples to electron […]

Dark Matter Constraints from a Unified Analysis of Strong Gravitational Lenses and Milky Way Satellite Galaxies

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Ethan O. Nadler, Simon Birrer, Daniel Gilman, Risa H. Wechsler, Xiaolong Du | Summary: Joint analyses of small-scale cosmological structure probes are relatively unexplored and promise to advance measurements of microphysical dark matter properties using heterogeneous data. Here, we present a multidimensional analysis of dark matter […]
