Resumen:
The main goal of this study is to analyze the clustering of galaxies around blazars. To carry this out, we estimated the two-point cross-correlation function between a sample of 427 BLLacertae (BL Lac) and 166 Flat Spectrum Radio Quasars (FSRQ) with a sample of non-active galaxies selected from SDSS. Blazars were chosen at z < 0.8 from Roma-BZCAT multi-frequency catalog, the largest list of gamma-ray detected blazars.We find that BL Lac are more strongly clustered than FSRQs at small end intermediate scales. There are also difference in the clustering between both Blazar populations and control inactive galaxies matched in redshift and colors. We also analized the properties of neighbouring galaxies around BL Lac and FSRQ. We found that inactive galaxies tend to be brighter and redder in nearby regions around both blazar populations, but there is no significant difference between the companions of BL Lac and FSRQ sources.
