ABRIDGED: Dorado is a nearby, rich and clumpy galaxy group that extends for several degrees in the Southern Hemisphere. For the first time, we map the Ha distribution as a possible indicator of star formation (SF) activity of Dorado members a large fraction of which show interaction and merging signatures. With the 2.5m du Pont and the 1m Swope telescopes we obtained narrow-band, calibrated images of 14 galaxies, forming the backbone of the group, mapping Ha+[N II] down to few 10$^{-17}$ erg~cm…

Dorado and its member galaxies II: A UVIT picture of the NGC 1533 substructure
Dorado is a nearby (17.69 Mpc) strongly evolving galaxy group in the Southern Hemisphere. We are investigating the star formation in this group. This paper provides a FUV imaging of NGC 1533, IC 2038


H i galaxies with little star formation: an abundance of LIERs
We present a sample of 91 H i galaxies with little or no star formation, and discuss the analysis of the integral field unit (IFU) spectra of 28 of these galaxies. We identified H i galaxies from
Hα imaging observations of early-type galaxies from the ATLAS3D survey
Context. The traditional knowledge of the mechanisms that brought to the formation and evolution of early type galaxies (ETG) in a hierarchical Universe was challenged by the unexpected finding by
On the origin of the faint-end of the red sequence in high-density environments
With the advent of the new generation wide-field cameras it became possible to survey in an unbiased mode galaxies spanning a variety of local densities, from the core of rich clusters, to compact
The Hα Galaxy Survey ⋆ I. The galaxy sample, Hα narrow-band observations and star formation parameters for 334 galaxies
We discuss the selection and observations of a large sample of nearby galaxies, which we are using to quantify the star formation activity in the local Universe. The sample consists of 334 galaxies
The ATLAS3D project - XIII. Mass and morphology of H I in early-type galaxies as a function of environment
We present the ATLAS3D H i survey of a volume-limited, complete sample of 166 nearby early-type galaxies (ETGs) brighter than MK=-21.5. The survey is mostly based on data taken with the Westerbork
The Dwarf Galaxy Population of the Dorado Group Down to MV ≈ −11*
We present V and I CCD photometry of suspected low surface brightness dwarf galaxies detected in a survey covering ~2.4 deg2 around the central region of the Dorado group of galaxies. The low surface
An Hα Imaging Survey of Galaxies in the Local 11 Mpc Volume
As part of a broader effort to characterize the population of star-forming galaxies in the local universe, we have carried out an H α + [N II] imaging survey for an essentially volume-limited sample
The Star Formation History of the Virgo Early-Type Galaxy NGC?4435: The Spitzer Mid-Infrared View
We present a population synthesis study of NGC 4435, an early-type Virgo galaxy interacting with NGC 4438. We combine new spectroscopic observations obtained with the Spitzer Space Telescope IRS
UV-optical colors as probes of early-type galaxy evolution
We have studied ~2100 early-type galaxies in the SDSS DR3 which have been detected by the GALEX Medium Imaging Survey (MIS), in the redshift range 0 < z < 0.11. Combining GALEX UV photometry with
Galaxy Groups Within 3500 km s -1
A study of the group properties of galaxies in our immediate neighborhood provides a singular opportunity to observationally constrain the halo mass function, a fundamental characterization of galaxy
