Cosmological evolution with decaying dark matter: an integral-equation approach
Nanoom Lee, Anna Bencke, Marc Kamionkowski +1
We present CLASSIER-DDM, an extension of the Boltzmann solver CLASSIER that implements the decaying dark matter (DDM) model via its integral-equation approach. The code handles gen…
Constraints with CMB lensing on dark matter decays to massive decay products
Anna Bencke, Nanoom Lee, Marc Kamionkowski
Motivated by the recent measurements by the Dark Energy Spectroscopic Instrument (DESI) which suggest a late-time matter density approximately 5\% lower than that inferred from Pla…
Peculiar-velocity distribution functions and 21-cm fluctuations
Ryan Yuran Zhang, Marc Kamionkowski
Predictions for observables involving the cosmological 21-cm background require calculations of spatial correlations of star formation rate densities (SFRDs) which have a nonlinear…
Primordial Magnetic Fields at Cosmic Dawn: 21-cm Forecasts with HERA and SKA
Keduse Worku, Hector Afonso G. Cruz, Marc Kamionkowski
Primordial magnetic fields (PMFs) can enhance the abundance of low-mass halos during Cosmic Dawn by sourcing additional small-scale matter fluctuations. This enhanced small-scale p…
A search for successful and choked jets in nearby broad-lined Type Ic supernovae
Tanner O'Dwyer, Alessandra Corsi, Sheng Yang +16
The observational link between long gamma-ray bursts (GRBs) and broad-lined stripped-envelope core-collapse supernovae (SNe Ic-BL) is well established. Significant progress has bee…
Gravitational-Wave Propagation Through the Axiverse
Leah Jenks, Marc Kamionkowski
We study the effects of oscillating, ultralight scalar and pseudoscalar fields on the propagation of gravitational waves (GWs). We consider two potential couplings of the (pseudo)s…
