Imprint of DES super-structures on the Cosmic Microwave Background
A. Kovács, C. Sánchez, J. García-Bellido +58
Small temperature anisotropies in the Cosmic Microwave Background can be sourced by density perturbations via the late-time integrated Sachs-Wolfe effect. Large voids and superclus…
Measuring weak lensing correlations of Type Ia Supernovae
D. Scovacricchi, R. C. Nichol, E. Macaulay +1
We study the feasibility of detecting weak lensing spatial correlations between Supernova (SN) Type Ia magnitudes with present (Dark Energy Survey, DES) and future (Large Synoptic…
Dipolar modulation in the size of galaxies: The effect of Doppler magnification
Camille Bonvin, Sambatra Andrianomena, David Bacon +4
Objects falling into an overdensity appear larger on its near side and smaller on its far side than other objects at the same redshift. This produces a dipolar pattern of magnifica…
HI and cosmological constraints from intensity mapping, optical, and CMB surveys
Alkistis Pourtsidou, David Bacon, Robert Crittenden
We forecast constraints on neutral hydrogen (HI) and cosmological parameters using near-term intensity mapping surveys with instruments such as BINGO, MeerKAT, and the SKA, and Sta…
Unbiased contaminant removal for 3D galaxy power spectrum measurements
Benedict Bahr-Kalus, Will J Percival, David Bacon +1
We assess and develop techniques to remove contaminants when calculating the 3D galaxy power spectrum. We separate the process into three separate stages: (i) removing the contamin…
The effects of velocities and lensing on moments of the Hubble diagram
Edward Macaulay, Tamara M. Davis, Dario Scovacricchi +3
We consider the dispersion on the supernova distance-redshift relation due to peculiar velocities and gravitational lensing, and the sensitivity of these effects to the amplitude o…
