Cosmology with Tully-Fisher HI Galaxy Surveys

Joël Mayor, Anthony Carr, Khaled Said +7

The SKA Observatory will enable measurements of the Tully-Fisher relation for statistical samples of HI selected galaxies out to unprecedented depths and redshifts thanks to its un…

Unlocking the Full Potential of SKAO Extra-galactic Science with High-multiplex Optical Spectroscopy

Kenneth J Duncan, Natasha Maddox, Daniel J. B Smith +9

Parallel to the transformation in radio continuum and H I observations from SKAO pathfinders and precursors over the past decade has been the development of a new generation of mul…

Kinematically cold and warm planetary nebulae samples, HII regions and supernovae remnants in the disc of the face-on spiral galaxy NGC 628 (M74) -- The Planetary Nebulae Spectrograph with the H arm

Magda Arnaboldi, Ortwin Gerhard, Surya Aniyan +14

We present the results for the galaxy NGC 628 observed with the Planetary Nebulae Spectrograph (PN.S) equipped with the H arm. With the third PN.S arm, the H arm, we measur…

MIGHTEE-HI: Mass Models and Dark Matter properties

Anastasia A. Ponomareva, P. E. Mancera Piña, A. A. Vărăşteanu +17

Measuring galaxy rotation curves is critical for inferring the properties of dark-matter haloes in the Lambda Cold Dark Matter (CDM) paradigm. We present HI rotation curves and…

MIGHTEE-HI: The radial acceleration relation with resolved stellar mass measurements

Andreea A. Vărăşteanu, Matt J. Jarvis, Anastasia A. Ponomareva +8

The radial acceleration relation (RAR) is a fundamental relation linking baryonic and dark matter in galaxies by relating the observed acceleration derived from dynamics to the one…

Photometry and kinematics of dwarf galaxies from the Apertif HI survey

Barbara Å iljeg, Elizabeth A. K. Adams, Filippo Fraternali +13

Context. Understanding the dwarf galaxy population in low density environments is crucial for testing the LCDM cosmological model. The increase in diversity towards low mass galaxi…
