The Delegate Survey: KOALA/AAOmega-IFU spectroscopy of three nearby dwarf galaxies
Kyungdo Ko, Helmut Jerjen, Sarah M. Sweet +6
Assessing the cosmological typicality of the Local Group is crucial for establishing whether its dwarf galaxy population is representative. To this end, the Delegate Survey targets…
The initial conditions and initial mass functions of Alpha Persei, Pleiades and Praesepe
L. Hobart, H. Baumgardt, S. Sweet
We have determined the initial mass function (IMF) and structural properties of the open clusters Alpha Persei, Pleiades and Praesepe using Gaia DR3 astrometry and photometry. Clus…
The coherent satellite velocity field around the interacting spiral galaxy pair NGC5713/19: signature of two galaxy groups merging
Helmut Jerjen, Simon Deeley, Holger Baumgardt +1
The luminous spirals NGC5713 and NGC5719 form an interacting galaxy pair 94 kpc apart and are connected by a straight, elongated neutral hydrogen structure extending over 200 kpc.…
Reevaluating UMa3/U1: star cluster or the smallest known galaxy?
Scot Devlin, Holger Baumgardt, Sarah M. Sweet
Ursa Major III/UNIONS 1 (UMa3/U1) is the faintest Milky Way satellite discovered to date, exhibiting a half-light radius of 3 1 pc and an absolute V-band magnitude of +2.2 $\…
Supermassive black holes in a mass-limited galaxy sample
Zachary Byrne, Michael J. Drinkwater, Holger Baumgardt +8
The observed scaling relations between supermassive black hole masses and their host galaxy properties indicate that supermassive black holes influence the evolution of galaxies. H…
No evidence for intermediate-mass black holes in the globular clusters Cen and NGC 6624
Holger Baumgardt, Chenyu He, Sarah M. Sweet +8
We compare the results of a large grid of N-body simulations with the surface brightness and velocity dispersion profiles of the globular clusters Cen and NGC 6624. Our models…
Near-identical star formation rate densities from H and FUV at redshift zero
Fiona M. Audcent-Ross, Gerhardt R. Meurer, O. I. Wong +27
For the first time both H and far-ultraviolet (FUV) observations from an HI-selected sample are used to determine the dust-corrected star formation rate density (SFRD: )…
Choirs, HI Galaxy Groups: Catalogue and Detection of Star-forming Dwarf Group Members
Sarah M. Sweet, Gerhardt Meurer, Michael J. Drinkwater +24
Hα observations centred on galaxies selected from the HI Parkes All Sky Survey (HIPASS, Barnes et al. 2001) typically show one and sometimes two star-forming galaxies within the ap…
