We present the results from an X-ray and optical survey of a sample of radio jets in AGN with Chandra and HST. We focus on the first six sources observed at X-rays, in four of which a bright X-ray jet was detected for the first time. In three out of four cases optical emission from the jet is also detected in the HST images. We compare the X-ray

We present the photometric results of the Chandra Multiwavelength Plane Survey (ChaMPlane), which is a project to identify a large sample of serendipitous X-ray sources in the galactic plane, in order to determine the populations of accretion-powered binaries in the Galaxy. Deep Chandra field observations have sufficient sensitivity to reach

The ChaMPlane survey of the galactic plane ( ~100 ACIS fields over 5 years, selected for exposure at least ~20ksec, galactic latitude below ~10deg, and minimum column density NH), will provide the largest sample of faint galactic x-ray sources. The arcsec positions for most of these will allow unambiguous optical identifications from our NOAO Long

We compare the rate of kinetic energy injected by stellar winds into the extragalactic H II region NGC 2363 to the luminosity needed to feed the observed temperature fluctuations. The kinetic luminosity associated to the winds is estimated by means of two different evolutionary synthesis codes, one of which takes into account the statistical
