Constraining accuracy of the pairwise velocities in -body simulations using scale-free models
Sara Maleubre, Daniel J. Eisenstein, Lehman H. Garrison +1
We present a continuation of an analysis that aims to quantify resolution of -body simulations by exploiting large (up to ) simulations of scale-free cosmologies run u…
Constraining νΛCDM with density-split clustering
Enrique Paillas, Carolina Cuesta-Lazaro, Pauline Zarrouk +6
The dependence of galaxy clustering on local density provides an effective method for extracting non-Gaussian information from galaxy surveys. The two-point correlation function (2…
Target Selection and Validation of DESI Emission Line Galaxies
A. Raichoor, J. Moustakas, Jeffrey A. Newman +48
The Dark Energy Spectroscopic Instrument (DESI) will precisely constrain cosmic expansion and the growth of structure by collecting 40 million extra-galactic redshifts across…
Target Selection and Validation of DESI Quasars
Edmond Chaussidon, Christophe Yèche, Nathalie Palanque-Delabrouille +54
The Dark Energy Spectroscopic Instrument (DESI) survey will measure large-scale structures using quasars as direct tracers of dark matter in the redshift range 0.9<z<2.1 and using…
DESI Bright Galaxy Survey: Final Target Selection, Design, and Validation
ChangHoon Hahn, Michael J. Wilson, Omar Ruiz-Macias +57
Over the next five years, the Dark Energy Spectroscopic Instrument (DESI) will use 10 spectrographs with 5000 fibers on the 4m Mayall Telescope at Kitt Peak National Observatory to…
Galaxy clustering from the bottom up: A Streaming Model emulator I
Carolina Cuesta-Lazaro, Takahiro Nishimichi, Yosuke Kobayashi +9
In this series of papers, we present a simulation-based model for the non-linear clustering of galaxies based on separate modelling of clustering in real space and velocity statist…
The Uchuu-SDSS galaxy lightcones: a clustering, RSD and BAO study
C. A. Dong-Páez, A. Smith, A. O. Szewciw +11
We present the data release of the Uchuu-SDSS galaxies: a set of 32 high-fidelity galaxy lightcones constructed from the large Uchuu 2.1 trillion particle -body simulation using…
A Probabilistic Autoencoder for Type Ia Supernovae Spectral Time Series
George Stein, Uros Seljak, Vanessa Bohm +37
We construct a physically-parameterized probabilistic autoencoder (PAE) to learn the intrinsic diversity of type Ia supernovae (SNe Ia) from a sparse set of spectral time series. T…
Assessing theoretical uncertainties for cosmological constraints from weak lensing surveys
Ting Tan, Dominik Zuercher, Janis Fluri +3
Weak gravitational lensing is a powerful probe which is used to constrain the standard cosmological model and its extensions. With the enhanced statistical precision of current…
A lightcone catalogue from the Millennium-XXL simulation: improved spatial interpolation and colour distributions for the DESI BGS
Alex Smith, Shaun Cole, Cameron Grove +2
The use of realistic mock galaxy catalogues is essential in the preparation of large galaxy surveys, in order to test and validate theoretical models and to assess systematics. We…
Cosmological perturbation theory using generalized Einstein de Sitter cosmologies
Michael Joyce, Azrul Pohan
The separable analytical solution in standard perturbation theory for an Einstein de Sitter (EdS) universe can be generalized to the wider class of such cosmologies (``generalized…
Solving small-scale clustering problems in approximate lightcone mocks
Alex Smith, Shaun Cole, Cameron Grove +2
Realistic lightcone mocks are important in the clustering analyses of large galaxy surveys. For simulations where only the snapshots are available, it is common to create approxima…
Designing an Optimal LSST Deep Drilling Program for Cosmology with Type Ia Supernovae
Philippe Gris, Nicolas Regnault, Humna Awan +8
The Vera C. Rubin Observatory's Legacy Survey of Space and Time is forecast to collect a large sample of Type Ia supernovae (SNe Ia) that could be instrumental in unveiling the nat…
The effect of quasar redshift errors on Lyman- forest correlation functions
Samantha Youles, Julian E. Bautista, Andreu Font-Ribera +30
Using synthetic Lyman- forests from the Dark Energy Spectroscopic Instrument (DESI) survey, we present a study of the impact of errors in the estimation of quasar redshift on th…
Forecasts for WEAVE-QSO: 3D clustering and connectivity of critical points with Lyman- tomography
Katarina Kraljic, Clotilde Laigle, Christophe Pichon +12
The upcoming WEAVE-QSO survey will target a high density of quasars over a large area, enabling the reconstruction of the 3D density field through Lyman- tomography over unprece…
