Cosmicflows-4: The Catalog of ~10000 Tully-Fisher Distances
Ehsan Kourkchi, R. Brent Tully, Sarah Eftekharzadeh +14
We present the distances of 9792 spiral galaxies lying within 15,000 km/s using the relation between luminosity and rotation rate of spiral galaxies. The sample is dominantly, but…
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…
Cosmicflows-4: The Baryonic Tully-Fisher Relation Providing ~10,000 Distances
Ehsan Kourkchi, R. Brent Tully, Helene M. Courtois +2
The interstellar gas in spiral galaxies can constitute a significant fraction of the baryon mass and it has been demonstrated that the sum of stellar and gas components correlates…
