Star density profiles of six old star clusters in the Large Magellanic Cloud
B. Lanzoni, F. R. Ferraro, E. Dalessandro +7
We used resolved star counts from Hubble Space Telescope images to determine the center of gravity and the projected density profiles of 6 old globular clusters in the Large Magell…
High-resolution extinction map in the direction of the bulge globular cluster NGC 6440
Cristina Pallanca, Francesco R. Ferraro, Barbara Lanzoni +3
We used optical images acquired with the UVIS channel of the Wide Field Camera 3 on board of the Hubble Space Telescope to construct the first high-resolution extinction map in the…
The effect of the environment on the Faber Jackson relation
Paola Focardi, Nicola Malavasi
We investigate the effect of the environment on the Faber Jackson (FJ) relation, using a sample of 384 nearby elliptical galaxies and estimating objectively their environment on th…
The diverse X-ray properties of four truly isolated elliptical galaxies: NGC 2954, NGC 6172, NGC 7052, and NGC 7785
Elisabetta Memola, Ginevra Trinchieri, Anna Wolter +2
We investigate the X-ray properties of four isolated elliptical galaxies, selected from the Updated Zwicky Catalog according to strict isolation criteria. Isolated galaxies are not…
Deficiency of Broad Line AGNs in Compact Groups of Galaxies
M. A. Martinez, A. del Olmo, R. Coziol +1
Based on a new survey of AGN activity in Compact Groups of Galaxies, we report a remarkable deficiency of Broad Line AGNs as compared to Narrow Line AGNs. The cause of such deficie…
Nuclear activity in galaxy pairs: a spectroscopic analysis of 48 UZC-BGPs
Paola Focardi, Valentina Zitelli, Silvia Marinoni
Galaxy pairs are ideal sites in which to investigate the role of interaction on nuclear activity. For this reason we have undertaken a spectroscopic survey of a large homogeneous s…
