Context. Constraints on the origin and propagation of cosmic rays can be achieved by studying the variation in the spectral index of the synchrotron emission across external galaxies. Aims. To determine the variation in the nonthermal radio spectral index in the nearby spiral galaxy M33 at a linear resolution of 360 pc. Methods. We separate the thermal and nonthermal components of the radio con...

First results of X-ray source population studies in nearby galaxies show the potential of XMM-Newton observations. I will report on first XMM-Newton M31 results and on three of our XMM-Newton projects, an X-ray source population study in the Magellanic Clouds (MCs), a deep raster survey of M33, and an investigation of the hot interstellar medium (ISM) in the halo of edge-on galaxies. XMM-Newton...

We derive the basic properties of seven Galactic open clusters containing Cepheids and construct their periodluminosity (P-L) relations. For our cluster main-sequence fitting we extend previous Hyades-based empirical color-temperature corrections to hotter stars using the Pleiades as a template. We use BVICJHKs data to test the reddening law, and include metallicity effects to perform a more co...

We have thoroughly characterized the ultraviolet to near-infrared (0.15 2.2 μm) spectral energy distribution (SED) of the central parsec of the M33 nucleus through new infrared photometry and optical/near-infrared spectroscopy, combined with ultraviolet/optical observations from the literature and the HST archive. The SED shows evidence for a significant level of attenuation, which we model thr...
