نویسنده
چکیده
We have undertaken several projects with the purpose of determining accurate distances to nearby galaxies to calibrate the extragalactic distance scale. Specifically, I describe the DIRECT project which aims to derive the distance to M31 and M33 directly, using detached eclipsing binaries and the Baade-Wesselink method for Cepheids. I also present a " hybrid " method of discovering Cepheids with ground-based telescopes using image subtraction and then following them up with the HST to derive Cepheid period-luminosity distances.

We present the GMRT 235 MHz images of three radio galaxies and 610 MHz images of two sources belonging to a complete sample of cD galaxies in rich and poor galaxy clusters. The analysis of the spectral properties confirms the presence of aged radio emission in two of the presented sources.

The observed luminosity distributions of X-ray sources suggest the presence of several populations of X-ray binaries in the nearby galaxies. Each population probably has a different formation and evolutionary history, depending on the intrinsic properties of the sources and the host environment. The features seen in the Log N (> S) – Log S plots for different galactic components and for differe...
