The DESI DR1 Peculiar Velocity Survey: growth rate measurements from the maximum likelihood fields method
Y. Lai, C. Howlett, J. Aguilar +60
We present the constraint on the growth rate of structure from the combination of DESI DR1 BGS sample, Fundamental Plane, and Tully-Fisher peculiar velocity catalogues using the ma…
The velocity coherence scale: a novel probe of cosmic homogeneity and a potential standard ruler
Leonardo Giani, Cullan Howlett, Chris Blake +2
We introduce the velocity coherence scale , the scale at which the spherical volume average of the trace of the velocity correlation tensor transitions from scaling faster tha…
The DESI DR1 Peculiar Velocity Survey: Mock Catalog
J. Bautista, A. J. Amsellem, V. Aronica +59
We describe the production of the official set of mock catalogs for the Dark Energy Spectroscopic Instrument Peculiar Velocity Survey (DESI-PV) Data Release 1 (DR1). Our mock catal…
The DESI DR1 Peculiar Velocity Survey: The Tully-Fisher Distance Catalog
K. Douglass, S. BenZvi, A. G. Kim +64
We calibrate the Tully-Fisher relation (TFR) using observations of spiral galaxies taken during the first year (DR1) of the DESI galaxy redshift survey. The rotational velocities o…
The DESI DR1 Peculiar Velocity Survey: global zero-point and constraints
A. Carr, C. Howlett, A. J. Amsellem +55
The Dark Energy Spectroscopic Instrument (DESI) in its first Data Release (DR1) already provides more than 100,000 galaxies with relative distance measurements. The primary purpose…
The DESI DR1 peculiar velocity survey: growth rate measurements from the galaxy power spectrum
F. Qin, C. Blake, C. Howlett +63
The large-scale structure of the Universe and its evolution encapsulate a wealth of cosmological information. A powerful means of unlocking this knowledge lies in measuring the aut…
The DESI DR1 Peculiar Velocity Survey: growth rate measurements from galaxy and momentum correlation functions
R. J. Turner, C. Blake, F. Qin +61
Joint analysis of the local peculiar velocity and galaxy density fields offers a promising route to testing cosmological models of gravity. We present a measurement of the normalis…
The DESI DR1 Peculiar Velocity Survey: Fundamental Plane Catalogue
C. E. Ross, C. Howlett, J. R. Lucey +58
Measurements of peculiar velocities in the local Universe are a powerful tool to study the nature of dark energy at low () redshifts. Here we present the largest single se…
Detection of supernova magnitude fluctuations induced by large-scale structure
A. Nguyen, C. Blake, R. J. Turner +56
The peculiar velocities of supernovae and their host galaxies are correlated with the large-scale structure of the Universe, and can be used to constrain the growth rate of structu…
The role of peculiar velocity uncertainties in standard siren cosmology
Chris Blake, Ryan J. Turner
Local distance indicators such as standard sirens, in combination with spectroscopic redshift measurements of their host galaxies, allow us to estimate the present-day expansion ra…
Cosmology with Peculiar Velocity Surveys
Ryan J. Turner
Peculiar velocities are the motions of galaxies due to the gravitational influence of large-scale structure, and thus are an important cosmological probe of the underlying matter d…
Forecasting the accuracy of velocity-field reconstruction
Chris Blake, Ryan J. Turner
Joint analyses of the large-scale distribution of galaxies, and their motions under the gravitational influence of this density field, allow powerful tests of the cosmological mode…
Constraining modified gravity scenarios with the 6dFGS and SDSS galaxy peculiar velocity datasets
Stuart Lyall, Chris Blake, Ryan J. Turner
The detailed nature of dark energy remains a mystery, leaving the possibility that its effects might be explained by changes to the laws of gravity on large scales. The peculiar ve…
On the correlations of galaxy peculiar velocities and their covariance
Chris Blake, Ryan J. Turner
Measurements of the peculiar velocities of large samples of galaxies enable new tests of the standard cosmological model, including determination of the growth rate of cosmic struc…
Biases in velocity reconstruction: investigating the effects on growth rate and expansion measurements in the local universe
Ryan J. Turner, Chris Blake
The local galaxy peculiar velocity field can be reconstructed from the surrounding distribution of large-scale structure and plays an important role in calibrating cosmic growth an…
Testing modified gravity scenarios with direct peculiar velocities
Stuart Lyall, Chris Blake, Ryan Turner +2
The theoretical basis of dark energy remains unknown and could signify a need to modify the laws of gravity on cosmological scales. In this study we investigate how the clustering…
