Major impact from a minor merger - The extraordinary hot molecular gas flow in the Eye of the NGC 4194 Medusa galaxy
S. König, S. Aalto, S. Muller +6
Minor mergers are important processes contributing significantly to how galaxies evolve across the age of the Universe. Their impact on supermassive black hole growth and star form…
The LOFAR Multifrequency Snapshot Sky Survey (MSSS) I. Survey description and first results
G. H. Heald, R. F. Pizzo, E. Orrú +147
We present the Multifrequency Snapshot Sky Survey (MSSS), the first northern-sky LOFAR imaging survey. In this introductory paper, we first describe in detail the motivation and de…
The WSRT HALOGAS Survey
George Heald, the HALOGAS Team
We present an overview of the HALOGAS (Hydrogen Accretion in LOcal GAlaxieS) Survey, which is the deepest systematic investigation of cold gas accretion in nearby spiral galaxies t…
Molecular tendrils feeding star formation in the Eye of the Medusa - The Medusa merger in high resolution 12CO 2-1 maps
S. König, S. Aalto, L. Lindroos +5
Studying molecular gas properties in merging galaxies gives us important clues to the onset and evolution of interaction-triggered starbursts. NGC4194 is particularly interesting t…
HALOGAS observations of NGC 4414: fountains, interaction, and ram pressure
W. J. G. de Blok, G. I. G. Józsa, M. Patterson +7
We present deep HI imaging of the nearby spiral galaxy NGC 4414, taken as part of the Westerbork HALOGAS (Hydrogen Accretion in LOcal GAlaxieS) survey. The observations show that N…
Evidence for an Interaction in the Nearest Starbursting Dwarf Irregular Galaxy IC 10
David L. Nidever, Trisha Ashley, Colin T. Slater +10
Using deep 21-cm HI data from the Green Bank Telescope we have detected an ~18.3 kpc-long gaseous extension associated with the starbursting dwarf galaxy IC 10. The newly-found fea…
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…
Molecules as tracers of galaxy evolution: an EMIR survey. I. Presentation of the data and first results
F. Costagliola, S. Aalto, M. I. Rodriguez +10
We investigate the molecular gas properties of a sample of 23 galaxies in order to find and test chemical signatures of galaxy evolution and to compare them to IR evolutionary trac…
The molecular gas content of the advanced S+E merger NGC 4441 - Evidence for an extended decoupled nuclear disc?
E. Juette, S. Aalto, S. Huettemeister
Mergers between a spiral and an elliptical (S+E mergers) are poorly studied so far despite the importance for galaxy evolution. NGC4441 is a nearby candidate for an advanced remnan…
