CHANCES, the Chilean Cluster Galaxy Evolution Survey: Selection and initial characterisation of clusters and superclusters
Cristóbal Sifón, Alexis Finoguenov, Christopher P. Haines +43
CHANCES, the CHileAN Cluster galaxy Evolution Survey, will study the evolution of galaxies in and around 100 massive galaxy clusters from the local Universe out to , and…
WALLABY Pilot Survey: the Tully-Fisher relation in the NGC 4808, Vela and NGC 5044 fields
Jeremy Mould, T. H. Jarrett, Hélène Courtois +18
The Tully-Fisher Relation (TFR) is a well-known empirical relationship between the luminosity of a spiral galaxy and its circular velocity, allowing us to estimate redshift indepen…
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…
Anisotropic satellite accretion onto the Local Group with HESTIA
Alexandra Dupuy, Noam I. Libeskind, Yehuda Hoffman +9
How the cosmic web feeds halos, and fuels galaxy formation is an open question with wide implications. This study explores the mass assembly in the Local Group within the context o…
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…
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…
Cosmicflows 4: The Calibration of Optical and Infrared Tully-Fisher Relations
Ehsan Kourkchi, R. Brent Tully, Gagandeep S. Anand +5
This study is a part of the Cosmicflows-4 project with the aim of measuring the distances of more than ~10,000 spiral galaxies in the local universe up to ~15,000 km/s. New HI line…
Global Attenuation in Spiral Galaxies in Optical and Infrared Bands
Ehsan Kourkchi, R. Brent Tully, J. Don Neill +3
The emerging light from a galaxy is under the influence of its own interstellar medium, as well as its spatial orientation. Considering a sample of 2,239 local spiral galaxies in o…
