Gasflows in Barred Galaxies with Big Orbital Loops-A Comparative Study of Two Hydrocodes

Stavros Pastras, Panos A. Patsis, E. Athanassoula

We study the flow of gas in a barred-galaxy model, in which a considerable part of the underlying stable periodic orbits have loops where, close to the ends of the bar, several orb…

Uncovering Extraplanar Gas in UGCA 250 with the Ultra-deep MHONGOOSE Survey

Sushma Kurapati, D. J. Pisano, W. J. G. de Blok +28

We use the neutral atomic hydrogen (HI) observations of the edge-on galaxy UGCA 250, taken as part of the MeerKAT HI Observations of Nearby Galactic Objects - Observing Southern Em…

Connection between Non-Axisymmetric Structures and Neutral Gas Distribution in Disk Galaxies

Ze-Zhong Liang, Jing Wang, Hua Gao +2

Non-axisymmetric structures, such as bars and spiral arms, are known to concentrate molecular gas and star formation in galaxy centers, actively building up the pseudo-bulges. Howe…

MHONGOOSE -- A MeerKAT Nearby Galaxy HI Survey

W. J. G. de Blok, J. Healy, F. M. Maccagni +57

The MHONGOOSE (MeerKAT HI Observations of Nearby Galactic Objects: Observing Southern Emitters) survey maps the distribution and kinematics of the neutral atomic hydrogen (HI) gas…

Bar Properties as a Function of Wavelength: A Local Baseline with S4G for High-Redshift Studies

Karín Menéndez-Delmestre, Thiago S. Gonçalves, Kartik Sheth +10

The redshift evolution of bars is an important signpost of the dynamic maturity of disk galaxies. To characterize the intrinsic evolution safe from band-shifting effects, it is nec…

A JWST investigation into the bar fraction at redshifts 1 < z < 3

Zoe A. Le Conte, Dimitri A. Gadotti, Leonardo Ferreira +7

The presence of a stellar bar in a disc galaxy indicates that the galaxy hosts in its main part a dynamically settled disc and that bar-driven processes are taking place in shaping…
