DOI: 10.1093/mnras/stab2009
Abstract: We generate constrained realizations (CRs) of the density and peculiar velocity fields within 200 h−1 Mpc from the final release of the Two-Micron All-Sky Redshift Survey (2MRS) – the densest all-sky redshift survey to date. The CRs… read more here.

Abstract: The Wiener Filter (WF) technique enables the reconstruction of density and velocity fields from observed radial peculiar velocities. This paper aims at identifying the optimal design of peculiar velocity surveys within the WF framework. The… read more here.

Abstract: The velocity of the Sun with respect to the cosmic microwave background (CMB) can be extracted from the CMB dipole, provided its intrinsic dipole is assumed to be small in comparison. This interpretation is consistent,… read more here.
