Red-channel (6000-8000 Å) nuclear spectra of 376 local galaxies
Giuseppe Gavazzi, Guido Consolandi, Massimo Dotti +4
We obtained long-slit optical spectra of the nuclear regions of 376 galaxies in the local Universe using the 1.5m Cassini telescope of Bologna Observatory. Of these spectra, 164 we…
Halpha3: an Halpha imaging survey of HI selected galaxies from ALFALFA. III. Nurture shapes up the Hubble sequence in the Great Wall
Giuseppe Gavazzi, Giulia Savorgnan, Matteo Fossati +7
We present the analysis of Halpha3, an Halpha imaging survey of galaxies selected from the HI ALFALFA Survey in the Coma Supercluster. By using the Halpha line as a tracer of the "…
Halpha3: an Halpha imaging survey of HI selected galaxies from ALFALFA. IV. Structure of galaxies in the Local and Coma Superclusters
Matteo Fossati, Giuseppe Gavazzi, Giulia Savorgnan +6
We present the analysis of the galaxy structural parameters from Halpha3, an Halpha narrow-band imaging follow-up survey of ~800 galaxies selected from the HI ALFALFA Survey in the…
Halpha3: an Halpha imaging survey of HI selected galaxies from ALFALFA. II. The star formation properties of galaxies in the Virgo cluster and surroundings
Giuseppe Gavazzi, Michele Fumagalli, Matteo Fossati +5
We present the analysis of Halpha3, an Halpha imaging survey of 409 galaxies selected from the HI Arecibo ALFALFA Survey in the Local Supercluster, including the Virgo cluster. We…
