Compositional properties of planet-crossing asteroids from astronomical surveys
A. V. Sergeyev, B. Carry, M. Marsset +8
Context. The study of planet-crossing asteroids is of both practical and fundamental importance. As they are closer than asteroids in the Main Belt, we have access to a smaller siz…
An high definition view of the COSMOS Wall at z~0.73
A. Iovino, V. Petropoulou, M. Scodeggio +14
We present a study of a large filamentary structure at z~0.73 in the field of the COSMOS survey, the so-called COSMOS Wall. This structure encompasses a comprehensive range of envi…
Aperture effects on the oxygen abundance determinations from CALIFA data
J. Iglesias-Páramo, J. M. Vílchez, F. F. Rosales-Ortega +23
This paper aims at providing aperture corrections for emission lines in a sample of spiral galaxies from the Calar Alto Legacy Integral Field Area Survey (CALIFA) database. In part…
Environmental imprint on galaxy chemical enrichment
Vasiliki Petropoulou, Jose Manuel Vilchez, Jorje Iglesias-Paramo
Recent results are presented on the metal enrichment of low-mass star-forming (SF) galaxies in local Universe clusters. The environmental effects on the chemical evolution of these…
LUCIFER@LBT view of star-forming galaxies in the cluster 7C 1756+6520 at z~1.4
Laura Magrini, Veronica Sommariva, Giovanni Cresci +5
Galaxy clusters are key places to study the contribution of {\it nature} (i.e. mass, morphology) and {\it nurture} (i.e.environment) in the formation and evolution of galaxies. Rec…
Environmental Effects on the Metal Enrichment of Low Mass Galaxies in Nearby Clusters
Vasiliki Petropoulou, Jose Manuel Vilchez, Jorge Iglesias-Paramo
In this paper we study the chemical history of low-mass star-forming (SF) galaxies in the local Universe clusters Coma, A1367, A779, and A634. The aim of this work is to search for…
New insights on Stephan's Quintet: exploring the shock in three dimensions
J. Iglesias-Páramo, L. López-Martín, J. M. Vílchez +2
We carried out IFU optical spectroscopy on three pointings in and near the SQ shock. We used PMAS on the 3.5m Calar Alto telescope to obtain measures of emission lines that provide…
Spatially resolved spectroscopy and chemical history of star-forming galaxies in the Hercules cluster: the effects of the environment
V. Petropoulou, J. M. Vílchez, J. Iglesias-Páramo +4
Spatially resolved spectroscopy has been obtained for a sample of 27 star-forming (SF) galaxies selected from our deep Halpha survey of the Hercules cluster. We have applied spectr…
Star forming galaxies in the Hercules cluster: Halpha imaging of A2151
B. Cedres, J. Iglesias-Paramo, J. M. Vilchez +3
This paper presents the first results of an Halpha imaging survey of galaxies in the central regions of the A2151 cluster. A total of 50 sources were detected in Halpha. The morpho…
Surface density of the young cluster IC 348 in the Perseus molecular cloud
L. Cambresy, V. Petropoulou, M. Kontizas +1
The IC 348 young star cluster contains more than 300 confirmed members. It is embedded in the Perseus molecular cloud, making any clustering analysis subject to an extinction bias.…
