H IIRegion Statistics in Barred and Non-Barred Galaxies
(1996)
We present new high quality Ha continuum-subtracted images of the grand design galaxies NGC 157, NGC 3631, NGC 6764, and NGC 6951, two of them barred and two non-barred, and describe the statistical properties of the HII ...
Global morphology and physical relations between the stars, gas and dust in the disc and arms of M100
(1996)
We study star formation processes in the disc of the weakly barred grand design spiral galaxy M100 (NGC 4321) from a variety of images tracing recent massive star formation, old and young stars, dust, and neutral hydrogen. ...
H IIRegion Statistics in Barred and Non-Barred Galaxies
(Astronomical Society of the Pacific, 1996)
We present new high quality Ha continuum-subtracted images of the grand design galaxies NGC 157, NGC 3631, NGC 6764, and NGC 6951, two of them barred and two non-barred, and describe the statistical properties of the HII ...
A Search for Symmetries in the Star Formation Patterns of Spiral Disks: Barred Galaxies
(Astronomical Society of the Pacific, 1996)
The Ha brightness distribution of a face-on galaxy is a classical representation of the massive star formation rate per unit surface area. Here, we present a test for the degree of symmetry in this distribution, aimed at ...
M100 and NGC 6951: Morphological Clues to Central Dynamics
(Astronomical Society of the Pacific, 1996)
High-resolution optical and NIR observations are used to constrain a dynamical model of the circumnuclear star forming (SF) region in the barred galaxy M100 (NGC 4321). Small leading arms observed in our K-band image of ...
