Searching for signatures of inflationary massive fields in DESI Imaging data and Stage-V galaxy surveys
Walter Riquelme, Santiago Avila, Lucas Pinol +2
The paper studies how massive fields present during inflation could leave detectable signatures in galaxy clustering, using DESI imaging data and forecasting the capability of futu…
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…
Imaging systematics induced by galaxy sub-sample fluctuation: new systematics at second order
Hui Kong, Nora Elisa Chisari, Boris Leistedt +4
Imaging systematics refers to the inhomogeneous distribution of a galaxy sample caused by varying observing conditions and astrophysical foregrounds. Current mitigation methods cor…
DESI 2024 V: Full-Shape Galaxy Clustering from Galaxies and Quasars
A. G. Adame, J. Aguilar, S. Ahlen +195
We present the measurements and cosmological implications of the galaxy two-point clustering using over 4.7 million unique galaxy and quasar redshifts in the range divi…
Mitigating Imaging Systematics for DESI 2024 Emission Line Galaxies and Beyond
A. J. Rosado-MarÃn, A. J. Ross, H. Seo +56
Emission Line Galaxies (ELGs) are one of the main tracers that the Dark Energy Spectroscopic Instrument (DESI) uses to probe the universe. However, they are afflicted by strong spu…
DESI 2024 VII: Cosmological Constraints from the Full-Shape Modeling of Clustering Measurements
DESI Collaboration, A. G. Adame, J. Aguilar +210
We present cosmological results from the measurement of clustering of galaxy, quasar and Lyman- forest tracers from the first year of observations with the Dark Energy Spectros…
