Kathryns Wheel: A spectacular galaxy collision discovered in the Galactic neighbourhood
Quentin A. Parker, Albert A. Zijlstra, Milorad Stupar +4
We report the discovery of the closest collisional ring galaxy to the Milky Way. Such rare systems occur due to "bulls-eye" encounters between two reasonably matched galaxies. The…
Linking dust emission to fundamental properties in galaxies: The low-metallicity picture
A. Rémy-Ruyer, S. C. Madden, F. Galliano +15
In this work, we aim at providing a consistent analysis of the dust properties from metal-poor to metal-rich environments by linking them to fundamental galactic parameters. We con…
NGC4370: a case study for testing our ability to infer dust distribution and mass in nearby galaxies
S. Viaene, G. De Geyter, M. Baes +14
A fraction of the early-type galaxy population hosts a prominent dust lane. Methods to quantify the dust content of these systems based on optical imaging data usually yield dust m…
Dust energy balance study of two edge-on spiral galaxies in the Herschel-ATLAS survey
Gert De Geyter, Maarten Baes, Ilse De Looze +18
Interstellar dust in galaxies can be traced either through its extinction effects on the star light, or through its thermal emission at infrared wavelengths. Recent radiative trans…
ALMA observations of 99 GHz free-free and H40 line emission from star formation in the centre of NGC 253
G. J. Bendo, R. J. Beswick, M. J. D'Cruze +3
We present Atacama Large Millimeter/submillimeter Array observations of 99.02 GHz free-free and H40 emission from the centre of the nearby starburst galaxy NGC 253. We calculate…
Herschel-ATLAS: The Surprising Diversity of Dust-Selected Galaxies in the Local Submillimetre Universe
Christopher J. R. Clark, Loretta Dunne, Haley L. Gomez +19
We present the properties of the first 250 m blind sample of nearby galaxies (15 < D < 46 Mpc) containing 42 objects from the Herschel Astrophysical Terahertz Large Area Survey…
