Atmosphere mitigation in CMB observations using multi-frequency time-domain component separation
Julien Tang, Shamik Ghosh, Jacques Delabrouille +4
CMB observations from ground-based observatories are limited in sensitivity by the fluctuating emission from the Earth's atmosphere, mostly due to water vapor inhomogeneities. Even…
Extensive analysis of reconstruction algorithms for DESI 2024 baryon acoustic oscillations
X. Chen, Z. Ding, E. Paillas +64
Reconstruction of the baryon acoustic oscillation (BAO) signal has been a standard procedure in BAO analyses over the past decade and has helped to improve the BAO parameter precis…
Modified Gravity Constraints from the Full Shape Modeling of Clustering Measurements from DESI 2024
M. Ishak, J. Pan, R. Calderon +68
We present cosmological constraints on deviations from general relativity (GR) from the first-year of clustering observations from Dark Energy Spectroscopic Instrument (DESI) in co…
Value Added Catalog of physical properties of more than 1.3 million galaxies from the DESI Survey
M. Siudek, R. Pucha, M. Mezcua +50
Aims. We present an extensive catalog of the physical properties of more than a million galaxies within the Dark Energy Spectroscopic Instrument (DESI), one of the largest spectros…
Analytical and EZmock covariance validation for the DESI 2024 results
Daniel Forero-Sánchez, Michael Rashkovetskyi, Otávio Alves +44
The estimation of uncertainties in cosmological parameters is an important challenge in Large-Scale-Structure (LSS) analyses. For standard analyses such as Baryon Acoustic Oscillat…
STag II: Classification of Serendipitous Supernovae Observed by Galaxy Redshift Surveys
W. Davison, D. Parkinson, S. BenZvi +32
With the number of supernovae observed expected to drastically increase thanks to large-scale surveys like the Dark Energy Spectroscopic Instrument (DESI), it is necessary that the…
