Two physical regimes for the Giant HII Regions and Giant Molecular Clouds in the Antennae Galaxies
Javier Zaragoza-Cardiel, Joan Font, John E. Beckman +3
We have combined observations of the Antennae galaxies from the radio interferometer ALMA (Atacama Large Millimeter/submillimeter Array) and from the optical interferometer GHFa…
Kinematics of Arp 270: gas flows, nuclear activity and two regimes of star formation
J. Zaragoza-Cardiel, J. Font-Serra, J. E. Beckman +7
We have observed the Arp 270 system (NGC 3395 & NGC 3396) in Hα emission using the GHαFaS Fabry-Perot spectrometer on the 4.2m William Herschel Telescope (La Palma). In NGC 3396, w…
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…
The central region of M83: Massive star formation, kinematics, and the location and origin of the nucleus
J. H. Knapen, R. G. Sharp, S. D. Ryder +3
We report new near-IR integral field spectroscopy of the central starburst region of the barred spiral galaxy M83 obtained with CIRPASS on Gemini-S, which we analyse in conjunction…
An improved method for statistical studies of the internal kinematics of HII regions: the case of M 83
Javier Blasco-Herrera, Kambiz Fathi, John E. Beckman +8
We present the integrated Halpha emission line profile for 157 HII regions in the central 3.4' x 3.4' of the galaxy M 83 (NGC 5236). Using the Fabry-Perot interferometer GHaFaS, on…
The galaxy-wide distributions of mean electron density in the HII regions of M51 and NGC 4449
Leonel Gutiérrez, John E. Beckman
Using ACS-HST images to yield continuum subtracted photometric maps in Hαof the Sbc galaxy M51 and the dwarf irregular galaxy NGC 4449, we produced extensive (over 2000 regions for…
HII regions feeding the interstellar medium in M83
Javier Blasco-Herrera, Kambiz Fathi, John Beckman +5
We analyse the internal dynamics of star-forming HII regions and their efficiency in interacting with the ISM. We use GHaFaS (Fabry-Perot) data of the nearby spiral galaxy M83 to p…
