Can Fingers of God be Resummed?
Shi-Fan Chen, Alejandro Aviles
Fingers of God (FoGs), Doppler shifts due to the small-scale virial motions of galaxies, are one of the most significant challenges for analytic models of galaxy clustering in reds…
Field-level inference of growth rate from DESI BGS galaxy and ZTF supernova simulations
Corentin Ravoux, Bastien Carreres, Julian Bautista +60
Galaxy peculiar velocities are a powerful probe of the growth rate of structure at low redshifts (), measured through the combination . These constraints are imp…
Galaxy bias in the era of LSST: perturbative bias expansions
Andrina Nicola, Boryana Hadzhiyska, Nathan Findlay +14
Upcoming imaging surveys will allow for high signal-to-noise measurements of galaxy clustering at small scales. In this work, we present the results of the LSST bias challenge, the…
Validation of the Scientific Program for the Dark Energy Spectroscopic Instrument
DESI Collaboration, A. G. Adame, J. Aguilar +261
The Dark Energy Spectroscopic Instrument (DESI) was designed to conduct a survey covering 14,000 deg over five years to constrain the cosmic expansion history through precise m…
On the galaxy 3-point correlation function in Modified Gravity
Alejandro Aviles, Gustavo Niz
The next generation of galaxy surveys will provide highly accurate measurements of the large-scale structure of the Universe, allowing for more stringent tests of gravity on cosmol…
Impact of a Rapid Diluted Energy Density on the halo mass function
Dante V. Gomez-Navarro, Alejandro Aviles, Axel de la Macorra
We study dark energy cosmological models, extensions of the standard model of particles, characterized by having an extra relativistic energy density at very early times, and that…
