A plausible link between dynamically unsettled molecular gas and the radio jet in NGC 6328
Michalis Papachristou, Kalliopi Maria Dasyra, Juan Antonio Fernández-Ontiveros +5
We report the detection of outflowing molecular gas at the center of the nearby radio galaxy NGC6328 (z=0.014), which has a gigahertz-peaked spectrum radio core and a compact (2 pc…
The galactic acceleration scale is imprinted on globular cluster systems of early-type galaxies of most masses and on red and blue globular cluster subpopulations
Michal Bílek, Michael Hilker, Florent Renaud +3
Context. Globular clusters (GCs) carry information about the formation histories and gravitational fields of their host galaxies. Bílek et al. (2019, BSR19 hereafter) reported that…
ViCTORIA project: MeerKAT HI observations of the ram pressure stripped galaxy NGC 4523
A. Boselli, P. Serra, F. de Gasperin +22
We present the first results of a 21 cm HI line pilot observation carried out with MeerKAT in preparation for the ViCTORIA project, an untargeted survey of the Virgo galaxy cluster…
Asymmetries in random motions of neutral Hydrogen gas in spiral galaxies
P. Adamczyk, P. Amram, L. Chemin +4
(Abridged). It has been recently shown that random motions of the neutral Hydrogen gas of the Triangulum galaxy (M33) exhibit a bisymmetric perturbation which is aligned with the m…
Constraining the LyC escape fraction from LEGUS star clusters with SIGNALS HII region observations: A pilot study of NGC 628
J. W. Teh, K. Grasha, M. R. Krumholz +23
The ionising radiation of young and massive stars is a crucial form of stellar feedback. Most ionising (Lyman-continuum; LyC, ) photons are absorbed close to the stars tha…
AGN feedback in action in the molecular gas ring of the Seyfert galaxy NGC7172
A. Alonso-Herrero, S. Garcia-Burillo, M. Pereira-Santaella +14
We present new ALMA observations of the CO(3-2) transition and 854micron continuum at 0.06-0.3" resolution, together with new VLT/SINFONI observations of NGC7172. This is a luminou…
