An effective description of Laniakea: impact on cosmology and the local determination of the Hubble constant
L. Giani, C. Howlett, K. Said +2
We propose an effective model to describe the bias induced on cosmological observables by Laniakea, the gravitational supercluster hosting the Milky Way, which was defined using pe…
The Early Data Release of the Dark Energy Spectroscopic Instrument
DESI Collaboration, A. G. Adame, J. Aguilar +266
The Dark Energy Spectroscopic Instrument (DESI) completed its five-month Survey Validation in May 2021. Spectra of stellar and extragalactic targets from Survey Validation constitu…
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…
Target Selection for the DESI Peculiar Velocity Survey
Christoph Saulder, Cullan Howlett, Kelly A. Douglass +35
We describe the target selection and characteristics of the DESI Peculiar Velocity Survey, the largest survey of peculiar velocities (PVs) using both the fundamental plane (FP) and…
Large-scale motions and growth rate from forward-modelling Tully-Fisher peculiar velocities
Paula Boubel, Matthew Colless, Khaled Said +1
Peculiar velocities are an important probe of the mass distribution in the Universe and the growth rate of structure, directly measuring the effects of gravity on the largest scale…
Cross-correlating radial peculiar velocities and CMB lensing convergence
Leonardo Giani, Cullan Howlett, Rossana Ruggeri +3
We study, for the first time, the cross correlation between the angular distribution of radial peculiar velocities (PV) and the lensing convergence of cosmic microwave background (…
Cosmicflows-4
R. Brent Tully, Ehsan Kourkchi, Hélène M. Courtois +14
With Cosmicflows-4, distances are compiled for 55,877 galaxies gathered into 38,065 groups. Eight methodologies are employed, with the largest numbers coming from the correlations…
The DESI Survey Validation: Results from Visual Inspection of Bright Galaxies, Luminous Red Galaxies, and Emission Line Galaxies
Ting-Wen Lan, R. Tojeiro, E. Armengaud +79
The Dark Energy Spectroscopic Instrument (DESI) Survey has obtained a set of spectroscopic measurements of galaxies to validate the final survey design and target selections. To as…
The Pantheon+ Analysis: Cosmological Constraints
Dillon Brout, Dan Scolnic, Brodie Popovic +43
We present constraints on cosmological parameters from the Pantheon+ analysis of 1701 light curves of 1550 distinct Type Ia supernovae (SNe Ia) ranging in redshift from t…
The Sloan Digital Sky Survey Peculiar Velocity Catalogue
Cullan Howlett, Khaled Said, John R. Lucey +5
We present a new catalogue of distances and peculiar velocities (PVs) of early-type galaxies derived from Fundamental Plane (FP) measurements using data from the Sloan Dig…
The Pantheon+ Analysis: Improving the Redshifts and Peculiar Velocities of Type Ia Supernovae Used in Cosmological Analyses
Anthony Carr, Tamara M. Davis, Daniel Scolnic +4
We examine the redshifts of a comprehensive set of published Type Ia supernovae, and provide a combined, improved catalogue with updated redshifts. We improve on the original catal…
The Pantheon+ Analysis: Evaluating Peculiar Velocity Corrections in Cosmological Analyses with Nearby Type Ia Supernovae
Erik R. Peterson, W. D'Arcy Kenworthy, Daniel Scolnic +10
Separating the components of redshift due to expansion and peculiar motion in the nearby universe () is critical for using Type Ia Supernovae (SNe Ia) to measure the Hubble…
Cosmic Flow Measurement and Mock Sampling Algorithm of Cosmicflows-4 Tully-Fisher Catalogue
Fei Qin, David Parkinson, Cullan Howlett +1
Measurements of cosmic flows enable us to test whether cosmological models can accurately describe the evolution of the density field in the nearby Universe. In this paper, we meas…
Joint analysis of 6dFGS and SDSS peculiar velocities for the growth rate of cosmic structure and tests of gravity
Khaled Said, Matthew Colless, Christina Magoulas +2
Measurement of peculiar velocities by combining redshifts and distance indicators is a powerful way to measure the growth rate of cosmic structure and test theories of gravity at l…
