Initial Data Release from the INT Photometric H-alpha Survey of the Northern Galactic Plane (IPHAS)
E. A. Gonzalez-Solares, N. A. Walton, R. Greimel +47
The INT/WFC Photometric H-alpha Survey of the Northern Galactic Plane (IPHAS) is an imaging survey being carried out in H-alpha, r' and i' filters, with the Wide Field Camera (WFC)…
Evolution of Structure in Late-type Spiral Galaxies I: Ionized Gas Kinematics in NGC 628
Kambiz Fathi, John E. Beckman, Almudena Zurita +5
We study two dimensional Fabry-Perot interferometric observations of the nearby face-on late-type spiral galaxy, NGC 628, in order to analyse the ionized gas component of the inter…
Structure and evolution of star-forming gas in late-type spiral galaxies
Kambiz Fathi, John E. Beckman, Almudena Zurita +7
We study two dimensional Fabry-Perot interferometric observations of the nearby face-on late-type spiral galaxy, NGC 628. We investigate the role of the individual HII regions toge…
The INT Photometric H-alpha Survey of the Northern Galactic Plane (IPHAS)
Janet E. Drew, R. Greimel, M. J. Irwin +1
The INT Photometric Halpha Survey of the Northern Galactic Plane (IPHAS) is a 1800 square degrees CCD survey of the northern Milky Way spanning the latitude range -5 < b < +5 (degr…
The internal dynamical equilibrium of HII regions: a statistical study
M. Relano, J. E. Beckman, A. Zurita +2
We present an analysis of the integrated Halpha emission line profiles for the HII region population of the spiral galaxies NGC 1530, NGC 6951 and NGC 3359. We show that 70% of the…
Gas flows, star formation and galaxy evolution
John E. Beckman, Emilio Casuso, Almudena Zurita +1
In the first part of this article we show how observations of the chemical evolution of the Galaxy: G- and K-dwarf numbers as functions of metallicity, and abundances of the light…
Ionized gas kinematics and massive star formation in NGC 1530
A. Zurita, M. Relano, J. E. Beckman +1
We present emission line mapping of the strongly barred galaxy NGC 1530 obtained from Fabry-Perot interferometry in Halpha, at significantly enhanced angular resolution compared wi…
The origin of the ionization of the diffuse interstellar medium in spiral galaxies. II. Modelling the distribution of ionizing radiation in NGC 157
A. Zurita, J. E. Beckman, M. Rozas +1
In this paper we make a quantitative study of the hypothesis that the diffuse H-alpha emitted from the discs of spiral galaxies owes its origin to the ionizing photons escaping fro…
Populations of high-luminosity density-bounded H II regions in spiral galaxies? Evidence and implications
J. E. Beckman, M. Rozas, A. Zurita +2
(Abridged) We present evidence that the HII regions of high luminosity in disk galaxies may be density bounded, so that a significant fraction of the ionizing photons emitted by th…
The Hαemission of the spiral galaxy NGC 7479
Almudena Zurita, Maite Rozas, John E. Beckman
We use the catalogue of HII regions obtained from a high quality continuum-subtracted H image of the grand design spiral galaxy NGC 7479, to construct the luminosity function (L…
