Cosmological-perturbation equations from the total-angular-momentum formalism
Marc Kamionkowski, Robert R. Caldwell
We derive the equations for the linear evolution of cosmological perturbations using total-angular-momentum (TAM) waves. The cosmic microwave background temperature and polarizatio…
Resonant Gravitational Production of Chiral Dark Photons
Leah Jenks, Marc Kamionkowski, Edward W. Kolb
Vector fields with a chiral, parity-odd coupling to a pseudoscalar field are known to undergo resonant amplification. In this work, we study this phenomenon in the context of cosmo…
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…
