The Atacama Cosmology Telescope: Semi-Analytic Covariance Matrices for the DR6 CMB Power Spectra
Zachary Atkins, Zack Li, David Alonso +18
The Atacama Cosmology Telescope Data Release 6 (ACT DR6) power spectrum is expected to provide state-of-the-art cosmological constraints, with an associated need for precise error…
Catalog-based pseudo-s
Kevin Wolz, David Alonso, Andrina Nicola
We present a formalism to extract the angular power spectrum of fields sampled at a finite number of points with arbitrary positions -- a common situation for several catalog-based…
Tomographic constraints on the production rate of gravitational waves from astrophysical sources
David Alonso, Mehraveh Nikjoo, Arianna I. Renzini +2
Using an optimal quadratic estimator, we measure the large-scale cross-correlation between maps of the stochastic gravitational-wave intensity, constructed from the first three LIG…
Relativistic imprints on dispersion measure space distortions
Shohei Saga, David Alonso
We investigate the three-dimensional clustering of sources emitting electromagnetic pulses traveling through cold electron plasma, whose radial distance is inferred from their disp…
The Simons Observatory: impact of bandpass, polarization angle and calibration uncertainties on small-scale power spectrum analysis
S. Giardiello, M. Gerbino, L. Pagano +17
We study the effects due to mismatches in passbands, polarization angles, and temperature and polarization calibrations in the context of the upcoming cosmic microwave background e…
Impact of Galactic dust non-Gaussianity on searches for B-modes from inflation
Irene Abril-Cabezas, Carlos Hervías-Caimapo, Sebastian von Hausegger +2
A key challenge in the search for primordial B-modes is the presence of polarized Galactic foregrounds, especially thermal dust emission. Power-spectrum-based analysis methods gene…
The halo mass function in the cosmic web
Francesca von Braun-Bates, Hans A. Winther, David Alonso +1
An important indicator of modified gravity is the effect of the local environment on halo properties. This paper examines the influence of the local tidal structure on the halo mas…
