Resonant structure in the disks of spiral galaxies, using phase-reversals in streaming motions from 2D Hα Fabry-Perot spectroscopy
Joan Font, John E. Beckman, Benoît Epinat +3
In this article we introduce a technique for finding resonance radii in a disk galaxy. We use a two-dimensional velocity field in Hα emission obtained with Fabry-Perot interferomet…
Detection of infalling hydrogen in transfer between the interacting galaxies NGC 5426 and NGC 5427
Joan Font, John E. Beckman, Margarita Rosado +8
Using velocity tagging we have detected hydrogen from NGC 5426 falling onto its interacting partner NGC 5427. Our observations, with the GHaFaS Fabry-Perot spectrometer, produced m…
Properties of the HII region populations of M51 and NGC 4449 from Halpha images with ACS on HST
Leonel Gutiérrez, John E. Beckman, Valeria Buenrostro
We have used the images from the ACS on HST in Halpha, and in the neighboring continuum, to produce flux calibrated images of the large spiral galaxy M51, and the dwarf irregular N…
