An analytic approximation to the covariance between pre- and post-reconstruction galaxy two-point statistics
M. Maus, A. Baleato Lizancos, M. White +2
We present a simple analytic approximation for the covariance between pre-reconstruction galaxy power spectrum measurements and post-reconstruction two-point correlation functions.…
Precision Kinematic Sunyaev--Zel'dovich Measurements Across Halo Mass and Redshift with DESI DR2 and ACT DR6: Part I. Luminous Red Galaxies
F. J. Qu, B. Ried Guachalla, E. Schaan +51
We present the most precise measurements of the kinetic Sunyaev-Zel'dovich (kSZ) effect around luminous red galaxies to date, detecting the signal at significance in both ha…
Constraining primordial non-Gaussianity from DESI DR1 quasars and Planck PR4 CMB Lensing
Sofia Chiarenza, Alex Krolewski, Marco Bonici +54
We present the first measurement of local-type primordial non-Gaussianity from the cross-correlation between million spectroscopically confirmed quasars from the first data r…
Estimation and mitigation of foregrounds in projected kSZ velocity reconstruction
Carmen Embil Villagra, Fiona McCarthy, Antón Baleato Lizancos +2
The kSZ effect has recently emerged as a powerful probe for precision cosmology through its ability to reconstruct the large-scale velocity field. In particular, the kSZ-reconstruc…
Data Release 1 of the Dark Energy Spectroscopic Instrument
DESI Collaboration, M. Abdul Karim, A. G. Adame +306
In 2021 May the Dark Energy Spectroscopic Instrument (DESI) collaboration began a 5-year spectroscopic redshift survey to produce a detailed map of the evolving three-dimensional s…
Delensing CMB B-modes using galaxy surveys: the effect of galaxy bias and matter clustering non-linearities
Shengzhu Wang, Antón Baleato Lizancos, José Luis Bernal
The B-mode of polarization of the CMB is a uniquely powerful probe of gravitational waves produced in the very early Universe. But searches for primordial B-mode anisotropies must…
