Full calibration of the tomographic redshift distribution from the HSC PDR3 Shape Catalog with DESI
J. Choppin de Janvry, S. Gontcho A Gontcho, U. Seljak +53
The calibration of tomographic redshift distributions is essential for cosmological analysis of weak lensing data. In this work, we calibrate all four tomographic bins of the Hyper…
A halo model of extragalactic contamination to CMB lensing, delensing, and cross-correlations
A. Baleato Lizancos, W. Coulton, A. Challinor +2
CMB lensing reconstructions are a sensitive probe of the growth of structure across cosmic time and a key tool to sharpen investigations of the very early Universe via delensing. A…
A joint analysis of 3D clustering and galaxy x CMB-lensing cross-correlations with DESI DR1 galaxies
M. Maus, M. White, N. Sailer +58
The spectroscopic data from DESI Data Release 1 (DR1) galaxies enables the analysis of 3D clustering by fitting galaxy power spectra and reconstructed correlation functions in reds…
Removal of interloper contamination to line-intensity maps using correlations with ancillary tracers of the large-scale structure
José Luis Bernal, Antón Baleato Lizancos
Line-intensity mapping (LIM) offers an approach to obtain three-dimensional maps of the large-scale structure by collecting the aggregate emission from all emitters along the line…
The Simons Observatory: Science Goals and Forecasts for the Enhanced Large Aperture Telescope
The Simons Observatory Collaboration, M. Abitbol, I. Abril-Cabezas +419
We describe updated scientific goals for the wide-field, millimeter-wave survey that will be produced by the Simons Observatory (SO). Significant upgrades to the 6-meter SO Large A…
Selecting samples of galaxies with fewer Fingers-of-God
Antón Baleato Lizancos, Uroš Seljak, Minas Karamanis +2
The radial positions of galaxies inferred from their measured redshift appear distorted due to their peculiar velocities. We argue that the contribution from stochastic velocities…
