Cosmic Web Research with KAT-7, MeerKAT & FAST
Claude Carignan
The seven-dish KAT-7 array was built as an engineering test-bed for the 64-dish Karoo Array Telescope, known as MeerKAT, which is the South African precursor of the Square Kilometr…
Estimating non-circular motions in barred galaxies using numerical N-body simulations
Toky Randriamampandry, Francoise Combes, Claude Carignan +1
The observed velocities of the gas in barred galaxies are a combination of the azimuthally-averaged circular velocity and non-circular motions, primarily caused by gas streaming al…
KAT-7 Science Verification: Cold Gas, Star Formation, and Substructure in the Nearby Antlia Cluster
Kelley M. Hess, T. H. Jarrett, Claude Carignan +2
The Antlia Cluster is a nearby, dynamically young structure, and its proximity provides a valuable opportunity for detailed study of galaxy and group accretion onto clusters. We pr…
HI observations of the nearest starburst galaxy NGC 253 with the SKA precursor KAT-7
D. M. Lucero, C. Carignan, E. C. Elson +4
We present HI observations of the Sculptor Group starburst spiral galaxy NGC 253, obtained with the Karoo Array Telescope (KAT-7). KAT-7 is a pathfinder for the SKA precursor MeerK…
Kinematics and Mass Modeling of Messier 33: Halpha observations
Zacharie Sie Kam, Claude Carignan, Laurent Chemin +2
As part of a long-term project to revisit the kinematics and dynamics of the large disc galaxies of the Local Group, we present the first deep, wide-field (42' x 56') 3D-spectrosco…
