Luminosity function of clusters of galaxies
M. Paolillo, S. Andreon, G. Longo +5
The composite galaxy luminosity function (hereafter LF) of 39 Abell clusters of galaxies is derived by computing the statistical excess of galaxy counts in the cluster direction wi…
Dissecting the luminosity function of the Coma cluster of galaxies by means of CFHT wide field images
S. Andreon, J. -C. Cuillandre
By means of wide-field (42x28 arcmin) CCD images of the Coma cluster of galaxies and of control fields, taken at the Canada-France-Hawaii telescope with the CFH12K and UH8K cameras…
The Coma cluster luminosity function from ultraviolet to near-infrared
S. Andreon, J. -C. Cuillandre, R. Pello
[Abridged] The Coma cluster luminosity function (LF) from ultraviolet (2000 AA) to the near-infrared (H band) is summarized. In the UV the LF is very steep, much steeper than in th…
Deep near-infrared luminosity function of a cluster of galaxies at z=0.3
S. Andreon
The deep near-infrared luminosity function of AC118, a cluster of galaxies at z=0.3, is presented. AC118 is a bimodal cluster, as evidenced both by our near-infrared images of lens…
Groups and clusters detection on DPOSS catalogs
E. Puddu, E. De Filippis, V. Strazzullo +5
We discuss the implementation and validation of a procedure aimed to detect groups and clusters of galaxies in DPOSS catalogs.
Wide Field Imaging. I. Applications of Neural Networks to object detection and star/galaxy classification
S. Andreon, G. Gargiulo, G. Longo +2
[Abriged] Astronomical Wide Field Imaging performed with new large format CCD detectors poses data reduction problems of unprecedented scale which are difficult to deal with tradit…
Use of DPOSS data to study globular cluster halos: an application to M 92
V. Testa, S. R. Zaggia, S. Andreon +4
We exploited the large areal coverage offered by the DPOSS to analyze the outermost regions of the galactic globular cluster M 92. Two independent photometric reduction programs (S…
