Completing HI observations of galaxies II. The Coma Supercluster
G. Gavazzi, K. O'Neil, A. Boselli +1
High sensitivity 21-cm HI line observations, with an rms noise level of \sim 0.5 mJy, were made of 35 spiral galaxies in the Coma Supercluster, using the refurbished Arecibo telesc…
Halpha surface photometry of galaxies in nearby clusters. V: the survey completion
G. Gavazzi, A. Boselli, L. Cortese +4
We present the Halpha imaging observations of 273 late-type galaxies in the nearby rich galaxy clusters Virgo, A1367, Coma, Cancer, Hercules and in the Great Wall, carried out prim…
A Virgo high-resolution Halpha kinematical survey : II. The Atlas
L. Chemin, C. Balkowski, V. Cayatte +8
A catalog of ionized gas velocity fields for a sample of 30 spiral and irregular galaxies of the Virgo cluster has been obtained by using three-dimensional optical data. The aim of…
The Arecibo Legacy Fast ALFA Survey: I. Science Goals, Survey Design and Strategy
Riccardo Giovanelli, Martha P. Haynes, Brian R. Kent
The recently initiated Arecibo Legacy Fast ALFA (ALFALFA) survey aims to map 7000 square degrees of the high galactic latitude sky visible from Arecibo, providing a HI line spectra…
UV properties of early-type galaxies in the Virgo cluster
A. Boselli, L. Cortese, J. M. Deharveng +11
We study the UV properties of a volume limited sample of early-type galaxies in the Virgo cluster combining new GALEX far- (1530 A) and near-ultraviolet (2310 A) data with spectro-…
Star Formation in NGC5194 (M51a): The Panchromatic View from GALEX to Spitzer
D. Calzetti, R. C. Kennicutt, L. Bianchi +32
(Abridged) Far ultraviolet to far infrared images of the nearby galaxy NGC5194, from Spitzer, GALEX, Hubble Space Telescope and ground--based data, are used to investigate local an…
