Near-Infrared photometry of LMC cluster Reticulum
M. Dall'Ora, G. Bono, J. Storm +11
We present near-infrared (JKs) time series data of the Large Magellanic Cloud (LMC) cluster Reticulum. The observing strategy and data reduction (DAOPHOTII/ALLFRAME) allowed us to…
Preliminary results from VLT (FORS1) photometry of NGC 6397
G. Andreuzzi, V. Testa, G. Marconi +3
We present VLT (FORS1) photometry of the lower main sequence (MS) of the Galactic Globular Cluster (GGC) NGC 6397, for stars located in 2 fields extending from a region near the cl…
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…
Automated search for LSB galaxies
S. Sabatini, R. Scaramella, V. Testa +4
Low Surface Brightness Galaxies (LSBGs) today constitute the less known fraction of galaxies: their number density and their physical properties (e.g. luminosity, colour, dynamics)…
The Multiplicity Function of groups of galaxies from CRoNaRio catalogues
E. De Filippis, G. Longo, S. Andreon +4
The projected multiplicity function of galaxies gives (per square degree) the density of galaxy aggregates formed by N members. We use the CRoNaRio matched catalogues to derive the…
An automatic procedure to extract galaxy clusters from CRoNaRio catalogs
E. Puddu, S. Andreon, G. Longo +6
We present preliminary results of a simple peak finding algorithm applied to catalogues of galaxies, extracted from the Second Palomar Sky Survey in the framework of the CRoNaRio p…
