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…

Starburst galaxies in the Hydra I cluster

Clara C. de la Casa, Kelley M. Hess, Lourdes Verdes-Montenegro +10

We present a new catalog of 196 galaxies of the nearby Hydra I cluster out to 1.75, consisting of broad u,g,r,i,z along with narrowband H measurements. These…

Revealing hidden structures in the Zone of Avoidance -- a blind MeerKAT HI Survey of the Vela Supercluster

Sambatriniaina H. A. Rajohnson, Renée C. Kraan-Korteweg, Bradley S. Frank +7

We conducted the MeerKAT Vela Supercluster survey, named VelaHI, to bridge the gap between the Vela SARAO MeerKAT Galactic Plane Survey (VelaSMGPS, $-2^{\circ} \leq b \leq 1^…

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…

HI Galaxy Signatures in the SARAO MeerKAT Galactic Plane Survey -- III. Unveiling the obscured part of the Vela Supercluster

Sambatriniaina H. A. Rajohnson, Renée C. Kraan-Korteweg, Hao Chen +8

We conducted a search for HI emission of the gas-rich galaxies in the Vela region () to explore the Vela S…
