Resolving galaxy formation in the early Universe with BonFIRE and CampFIRE
Jenna Samuel, Michael Boylan-Kolchin, Robert Feldmann +16
The abundance and rapid growth of galaxies at cosmic dawn revealed by the James Webb Space Telescope challenges models of galaxy formation, motivating new simulations to uncover th…

CMB constraints on dark matter-proton scattering: investigating prior-volume effects using profile likelihoods
Maria C. Straight, Tanvi Karwal, José Luis Bernal +1
We present profile-likelihood constraints on velocity-independent dark matter-proton scattering, including cases in which only a fraction of dark matter has such non-gravitational…

Central densities of dark matter halos in FIRE-2 simulations of low-mass galaxies with cold dark matter and self-interacting dark matter
Maria C. Straight, Michael Boylan-Kolchin, James S. Bullock +6
We investigate the central density structure of dark matter halos in cold dark matter (CDM) and self-interacting dark matter (SIDM) models using simulations that are part of the Fe…
