Bars and the symmetry of star formation patterns in the discs of spiral galaxies
Rozas, M.; Knapen, J.; Beckman, J.E. (1998)We present a test for the degree of symmetry in the distribution of the Hα brightness along the arms of a sample of spiral galaxies. The test consists of deriving the cross-correlation function of the Hα brightness as a ... -
H IIRegion Statistics in Barred and Non-Barred Galaxies
Rozas, M.; Beckman, J.E.; Knapen, J. (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 ... -
H IIRegion Statistics in Barred and Non-Barred Galaxies
Rozas, M.; Beckman, J.E.; Knapen, J. (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 ... -
High-velocity gas in the luminous H II Regions of NGC 1530
Relano, M.; Beckman, J.E.; Zurita, A.; Rozas, M.; Knapen, J. (2002) -
Internal turbulence, virality, and density bounding of the most luminous H II regions in the spiral galaxy M 100
Rozas, M.; Sabalisck, N.; Beckman, J.E.; Knapen, J. (1998-10)We present TAURUS Fabry-Perot velocity data in Ha emission of the disc of the grand design spiral M 100 (NGC 4321). We have studied the emission spectra of the 200 Hii regions most luminous in H , calibrated in luminosity ... -
Kinematics of Ionized and Molecular Hydrogen in the Core of M100
Knapen, J.; Shlosman, I.; Heller, C.H.; Rand, R.J.; Beckman, J.E.; Rozas, M. (2000-01) -
Populations of high-luminosity density-bounded H II Regionsin Spiral Galaxies: Evidence and implications
Beckman, J.E.; Rozas, M.; Zurita, A.; Watson, R.A.; Knapen, J. (2000-06) -
A Search for Symmetries in the Star Formation Patterns of Spiral Disks: Barred Galaxies
Rozas, M.; Beckman, J.E.; Knapen, J. (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 ...
