Peculiar velocities at low Galactic latitude
Jeremy Mould, Helene M. Courtois, Renee C. Kraan-Korteweg +1
The Laniakea Supercluster is the closest large scale structure of galaxies. Is such a structure expected in the standard cold dark matter model of cosmology? This would be a relati…
Hidden Vela Supercluster Revealed by First Hybrid Redshift & Peculiar Velocity Reconstruction
A. M. Hollinger, H. M. Courtois, R. C. Kraan-Korteweg +2
A large fraction of the extragalactic sky is obscured by foreground dust and stars along the plane of the Milky Way, leaving a major gap (~ 20%) in whole-sky maps of large-scale st…
In search for the Local Universe dynamical homogeneity scale with CF4++ peculiar velocities
Helene M. Courtois, Jeremy Mould, Amber M. Hollinger +2
This article explores an update to the cosmography of the local Universe within z=0.1, incorporating galaxy peculiar velocity datasets from the first data releases of WALLABY, FAST…
Uncertainties in the Hubble Constant from Peculiar Velocities
Amber M. Hollinger, Michael J. Hudson
Recent measurements of the Hubble constant using type Ia supernovae explicitly correct for their estimated peculiar velocities using the 2M++ reconstruction of the local density fi…
