Ho'oleilana: An Individual Baryon Acoustic Oscillation?

R. Brent Tully, Cullan Howlett, Daniel Pomarede

Theory of the physics of the early hot universe leads to a prediction of baryon acoustic oscillations that has received confirmation from the pair-wise separations of galaxies in s…

WALLABY Pre-Pilot and Pilot Survey: the Tully Fisher Relation in Eridanus, Hydra, Norma and NGC4636 fields

Hélène M. Courtois, Khaled Said, Jeremy Mould +28

The WALLABY pilot survey has been conducted using the Australian SKA Pathfinder (ASKAP). The integrated 21-cm HI line spectra are formed in a very different manner compared to usua…

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…

Galaxy flows within 8,000 km/s from Numerical Action methods

Edward Shaya, R. Brent Tully, Daniel Pomarède +1

The trajectories since z=4 of systems of galaxies (`halos') with cz < 8,000 km/s are found through Numerical Action reconstructions. A set of 9,719 halos from a 2MASS group catalog…

Cosmicflows-3: The South Pole Wall

Daniel Pomarede, R. Brent Tully, Romain Graziani +3

Velocity and density field reconstructions of the volume of the universe within 0.05c derived from the Cosmicflows-3 catalog of galaxy distances has revealed the presence of a fila…

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…
