Secular Extragalactic Parallax: Measurement Methods and Predictions for Gaia
Jennie Paine, Jeremy Darling, Romain Graziani +1
Secular extragalactic parallax caused by the solar system's velocity relative to the cosmic microwave background rest frame may be observable as a dipole proper motion field with a…
Cosmicflows-3: Two DistanceVelocity Calculators
Ehsan Kourkchi, Helene M. Courtois, Romain Graziani +4
Tools are provided at the Extragalactic Distance Database website that provide relationships between the distances and velocities of galaxies based on smoothed versions of the velo…
A kinematic confirmation of the hidden Vela supercluster
Helene M. Courtois, Renee. C. Kraan-Korteweg, Alexandra Dupuy +2
The universe region obscured by the Milky Way is very large and only future blind large HI redshift, and targeted peculiar surveys on the outer borders will determine how much mass…
Partitioning the universe into gravitational basins using the cosmic velocity field
A. Dupuy, H. M. Courtois, F. Dupont +8
This letter presents a new approach using the cosmic peculiar velocity field to characterize the morphology and size of large scale structures in the local Universe. The algorithm…
Cosmicflows-3: Cosmography of the Local Void
R Brent Tully, Daniel Pomarede, Romain Graziani +3
Cosmicflows-3 distances and inferred peculiar velocities of galaxies have permitted the reconstruction of the structure of over and under densities within the volume extending to 0…
Testing Gravity Using Type Ia Supernovae Discovered by Next-Generation Wide-Field Imaging Surveys
A. G. Kim, G. Aldering, P. Antilogus +29
In the upcoming decade cadenced wide-field imaging surveys will increase the number of identified Type~Ia supernovae (SNe~Ia) from the hundreds to the hundreds of thousands…
The peculiar velocity field up to by forward-modeling Cosmicflows-3 data
R. Graziani, H. M. Courtois, G. Lavaux +4
A hierarchical Bayesian model is applied to the Cosmicflows-3 catalog of galaxy distances in order to derive the peculiar velocity field and distribution of matter within $z \sim 0…
