In this paper, we study the circumgalactic environment of LINER host galaxies, in a sample of 166 objects drawn from a Multifrequency Catalogue of LINERs by Carrillo et.1999). The aim of our work is to compare the environment of different types of LINERs, therefore we subdivided our sample in three groups: LINERs type, type, and transition objects

We present B,V photometric data of the Carina dwarf Spheroidal (dSph) galaxy, collected with the Mosaic Camera (36×36 arcmin2) available at the 4m CTIO Blanco telescope. We discuss different reduction strategies and in particular the PSF extraction and internal accuracy reached by our measurements. We discuss a new deep Color-Magnitude Diagram (CMD

We present B, V photometric data of the Carina Dwarf Spheroidal Galaxy (dSph), collected with the Wide Field Imager (WFI) available at the 2.2m MPI/ESO telescope. We briefly discuss the main features of the color magnitude diagram (CMD) and in particular the mix of stellar populations present in this galaxy. A preliminary analysis of the spatial

We present recent results on variable stars in the Carina Dwarf Galaxy based on B,V time series data collected over three consecutive nights with the Wide Field Imager available at the 2.2m ESO/MPI telescope. At present we have already detected and measured a sample of 92 variable stars. Among them 75 are RR Lyrae stars (54 fundamental, 15 first

We discuss the reduction strategy adopted to perform the relative and the absolute calibration of the Wide Field Imager (WFI) available at the 2.2m ESO/MPI telescope and of the Mosaic Camera (MC) available at the 4m CTIO Blanco telescope. To properly constrain the occurrence of deceptive systematic errors in the relative calibration we observed
