The implications of particle rotation on the effect of photophoresis
Janine van Eymeren, Gerhard Wurm
In a laboratory experiment, water-ice aggregates are trapped in a vacuum chamber at a pressure of 2 mbar due to photophoresis and thermophoresis. The particles are located between…
The intriguing HI gas in NGC 5253: an infall of a diffuse, low-metallicity HI cloud?
Angel R. Lopez-Sanchez, Baerbel Koribalski, Janine van Eymeren +4
(Abridged) We present new, deep HI line and 20-cm radio continuum data of the very puzzling blue compact dwarf galaxy NGC 5253, obtained with the ATCA as part of the `Local Volume…
Lopsidedness in WHISP galaxies: II. Morphological lopsidedness
J. van Eymeren, E. Juette, C. J. Jog +2
The distribution of stars and gas in many galaxies is asymmetric. This so-called lopsidedness is expected to significantly affect the dynamics and evolution of the disc, including…
Lopsidedness in WHISP galaxies: I. Rotation curves and kinematic lopsidedness
J. van Eymeren, E. Juette, C. J. Jog +2
The frequently observed lopsidedness of the distribution of stars and gas in disc galaxies is still considered as a major problem in galaxy dynamics. It is even discussed as an imp…
Lopsidedness in WHISP galaxies
Eva Juette, Janine van Eymeren, Chanda Jog +2
Observations of the stellar and gaseous components in disc galaxies often reveal asymmetries in the morphological and kinematic distribution. However, the origin of this effect is…
A kinematic study of the neutral and ionised gas in the irregular dwarf galaxies IC 4662 and NGC 5408
J. van Eymeren, B. S. Koribalski, A. R. Lopez-Sanchez +2
Abridged. The feedback between massive stars and the interstellar medium is one of the most important processes in the evolution of dwarf galaxies. This interaction results in nume…
Discovery of an unusual new radio source in the star-forming galaxy M82: Faint supernova, supermassive blackhole, or an extra-galactic microquasar?
T. W. B. Muxlow, R. J. Beswick, S. T. Garrington +7
A faint new radio source has been detected in the nuclear region of the starburst galaxy M82 using MERLIN radio observations designed to monitor the flux density evolution of the r…
A kinematic study of the irregular dwarf galaxy NGC 4861 using HI and Halpha observations
J. van Eymeren, M. Marcelin, B. S. Koribalski +4
Context. Outflows powered by the injection of kinetic energy from massive stars can strongly affect the chemical evolution of galaxies, in particular of dwarf galaxies, as their lo…
