Dorado and its member galaxies. Ha imaging of the group backbone
R. Rampazzo, S. Ciroi, P. Mazzei +9
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…
Morphology and surface photometry of a sample of isolated early-type galaxies from deep imaging
R. Rampazzo, A. Omizzolo, M. Uslenghi +5
Isolated early-type galaxies (iETGs) are evolving in unusually poor environments for this morphological family, which is typical of cluster inhabitants. We investigate the mechanis…
High resolution morphology and surface photometry of KIG 685 and KIG 895 with ARGOS+LUCI
R. Rampazzo, M. Uslenghi, I. Y. Giorgiev +14
We aim to refine the sample of isolated early-type galaxies in the AMIGA catalogue via high resolution imaging. Here we report the result from a pilot study investigating two candi…
A multi-wavelength study of the evolution of Early-Type Galaxies in Groups: the ultraviolet view
R. Rampazzo, P. Mazzei, A. Marino +5
ABRIDGED- The UV-optical color magnitude diagram (CMD) of rich galaxy groups is characterised by a well developed Red Sequence (RS), a Blue Cloud (BC) and the so-called Green Valle…
The NGC 454 system: anatomy of a mixed on-going merger
H. Plana, R. Rampazzo, P. Mazzei +3
This paper focuses on NGC 454, a nearby interacting pair of galaxies (AM0112-554, RR23), composed of an early-type (NGC 454 E) and a star forming late-type companion (NGC 454 W). W…
Investigating early-type galaxy evolution with a multiwavelength approach. II. The UV structure of 11 galaxies with Swift-UVOT
R. Rampazzo, P. Mazzei, A. Marino +6
GALEX detected a significant fraction of early-type galaxies showing Far-UV bright structures. These features suggest the occurrence of recent star formation episodes. We aim at un…
UGC 7639: a Dwarf Galaxy in the Canes Venatici I Cloud
L. M. Buson, D. Bettoni, P. Mazzei +1
We want to get insight into the nature, i.e. the formation mechanism and the evolution, of UGC 7639, a dwarf galaxy in the Canes Venatici I Cloud (CVnIC). We used archival GALEX (F…
The UV window on counter rotating ETGs: insight from SPH simulations with chemo-photometric implementation
Daniela Bettoni, Paola Mazzei, Roberto Rampazzo +3
The Galaxy Evolution Explorer (GALEX) detected ultraviolet emission in about 50% of multi-spin early-type galaxies (ETGs), suggesting the occurrence of a recent rejuvenation episod…
Galaxy evolution in groups. USGC U268 and USGC U376 in the Leo cloud
A. Marino, L. Bianchi, P. Mazzei +2
With the aim of investigating galaxy evolution in nearby galaxy groups, we analysed the spectral energy distribution of 24 galaxies, members of two groups in the Leo cloud, USGC U2…
Catching Spiral - S0 transition in groups. Insights from SPH simulations with chemo-photometric implementation
P. Mazzei, A. Marino, R. Rampazzo +2
We are investigating the co-evolution of galaxies within groups combining multi-wavelength photometric and 2D kinematical observations. Here we focus on S0s showing star formation…
Galaxy evolution in nearby groups. II. Galaxy evolution in nearby loose groups. II. Photometric and kinematic characterization of USGC U268 and USGC U376 group members in the Leo cloud
A. Marino, H. Plana, R. Rampazzo +8
We present the photometric and kinematic characterization of two groups, USGC U268 and USGC U376 located in different regions of the Leo cloud. U268, composed of 10 catalogued memb…
Hot gas in groups: NGC 5328 and the intriguing case of NGC 4756 with XMM-Newton
G. Trinchieri, A. Marino, P. Mazzei +2
[Abridged] NGC 5238 and NGC 4756 are the brightest unperturbed elliptical galaxies in their respective loose groups. In the present study we aim at characterizing the properties of…
The innermost region of the NGC 1023 Group: Insight into its evolution
D. Bettoni, L. M. Buson, P. Mazzei +1
The NGC 1023 group is one of the most studied nearby groups. We want to give an insight into the evolution of its innermost region by means of ultraviolet observations and proper m…
A multiwavelength study of the IRAS Deep Survey galaxy sample III. Spectral classification and dynamical properties
D. Bettoni, P. Mazzei, A. della Valle
The infrared deep sample (IDS), in the north ecliptical polar region (NEPR), is the first complete, far--IR selected sample, on which numerous studies of galaxy evolution are based…
