Reconstructing dark matter distribution with peculiar velocities: Bayesian forward modelling with corrections for inhomogeneous Malmquist bias
Supranta S. Boruah, Guilhem Lavaux, Michael J. Hudson
We present a forward-modelled velocity field reconstruction algorithm that performs the reconstruction of the mass density field using only peculiar velocity data. Our method consi…
New Constraints on Anisotropic Expansion from Supernovae Type Ia
W. Rahman, R. Trotta, S. S. Boruah +2
We re-examine the contentious question of constraints on anisotropic expansion from Type Ia supernovae (SNIa) in the light of a novel determination of peculiar velocities, which ar…
Peculiar-velocity cosmology with Types Ia and II supernovae
Benjamin E. Stahl, Thomas de Jaeger, Supranta S. Boruah +3
We present the Democratic Samples of Supernovae (DSS), a compilation of 775 low-redshift Type Ia and II supernovae (SNe Ia & II), of which 137 SN Ia distances are derived via the n…
KaRMMa -- Kappa Reconstruction for Mass Mapping
Pier Fiedorowicz, Eduardo Rozo, Supranta S. Boruah +2
We present KaRMMa, a novel method for performing mass map reconstruction from weak-lensing surveys. We employ a fully Bayesian approach with a physically motivated lognormal prior…
