Baryon number freeze-out in the Standard Model, precisely
Cristina Benso, Dietrich Bödeker, Kohei Kamada +4
Weak sphaleron transitions turn a lepton asymmetry of the Standard Model plasma in the early Universe into a baryon asymmetry, conserving baryon-minus-lepton number and its i…
A New Probe of Dark Matter Subhalos: Stellar Aberration with TESS
Matthias Daniel, Xiao Xue, Kris Pardo +1
Small-scale dark matter (DM) structure encodes key information about the particle nature of DM and therefore provides a sensitive test of competing models. Yet, it remains hidden f…
Survival of the most compact: the life and death of satellite halos in self-interacting dark matter
David Klemmer, Moritz S. Fischer, Kimberly K. Boddy +2
Self-interacting dark matter (SIDM) models feature short-range interactions between dark matter (DM) particles that lead to larger diversity in the inner parts of galactic rotation…

Massive boson stars are self-gravitating configurations of self-interacting scalar fields and can be modeled by a massive scalar field with a quartic self-interaction potential. It…
Forecasted Detection Limits on the (Dark) Matter Density in Supermassive Black Hole Binaries for LISA
Matthias Daniel, Kris Pardo, Laura Sagunski
Supermassive black hole binaries (SMBHBs) are among the most powerful known sources of gravitational waves (GWs). Accordingly, these systems could dominate GW emission in the micro…
