Molecular gas and star formation in GASP jellyfish galaxies
A. Moretti, R. Paladino, C. Bacchini +13
Several studies have reported a nearly linear correlation between the molecular gas and star formation rate surface density, the so-called Kennicutt-Schmidt (KS) law. We aim to ret…
Atomic hydrogen reservoirs in quiescent galaxies at z = 0.4
A. Bianchetti, G. Rodighiero, D. Donevski +11
Context. Based on Local Universe observations, quiescent galaxies (QGs) host lower to no HI compared to star-forming galaxies (SFGs), but no constraints have been derived so far at…
The GECKOS Survey: Resolved, multiphase observations of mass-loading and gas density in the galactic wind of NGC 4666
Barbara Mazzilli Ciraulo, D. B. Fisher, R. Elliott +24
We present a multiphase, resolved study of the galactic wind extending from the nearby starburst galaxy NGC 4666. For this we use VLT/MUSE observations from the GECKOS program and…
Gas-rich dwarf galaxy multiples in the Apertif HI survey
B. Å iljeg, E. A. K. Adams, F. Fraternali +8
Dwarf-dwarf galaxy encounters are a key aspect of galaxy evolution as they can ignite or temporarily suppress star formation in dwarfs and can lead to dwarf mergers. However, the f…
Photometric vs dynamical stellar masses and their impact on scaling relations in nearby disc galaxies
A. Marasco, S. M. Fall, E. M. Di Teodoro +1
The study of scaling relations of disc galaxies and their evolution across cosmic time requires accurate estimates of galaxy stellar masses over broad redshift ranges. Wh…
HI within and around observed and simulated galaxy discs -- Comparing MeerKAT observations with mock data from TNG50 and FIRE-2
A. Marasco, W. J. G. de Blok, F. M. Maccagni +12
Atomic hydrogen (HI) is an ideal tracer of gas flows in and around galaxies, and it is uniquely observable in the nearby Universe. Here we make use of wide-field (~1 square degree)…
