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…
The filling factor - radius relation for 58 HII regions across the disk of NGC6946
B. Cedrés, J. E. Beckman, A. Bongiovanni +5
Using the OSIRIS tunable narrow band imager on the 10.4m GTC (La Palma) we have mapped the SAB(rs)cd galaxy NGC 6946 over a 7.3x7.5 square arcminutes field in the emission lines of…
Hα Kinematics of S4G spiral galaxies-I. NGC 864
Santiago Erroz-Ferrer, Johan H. Knapen, Joan Font +22
We present a study of the kinematics of the isolated spiral galaxy NGC 864, using Hα Fabry-Perot data obtained with the GHαFaS instrument at the William Herschel Telescope in La Pa…
A Strong Dichotomy in S0 Disk Profiles Between the Virgo Cluster and the Field
Peter Erwin, Leonel Gutierrez, John E. Beckman
We report evidence for a striking difference between S0 galaxies in the local field and in the Virgo Cluster. While field S0 galaxies have disks whose surface-brightness profiles a…
The Outer Disks of Early-Type Galaxies. II. Surface-Brightness Profiles of Unbarred Galaxies and Trends with Hubble Type
Leonel Gutierrez, Peter Erwin, Rebeca Aladro +1
We present azimuthally averaged radial profiles of R-band surface brightness for a complete sample of 47 early-type, unbarred galaxies, as a complement to our previous study of ear…
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…
