... This thread contains a step-by-step recipe to extract MOS spectra of a point-like source observed in Imaging mode and to create associated response matrices, starting from a calibrated, concatenated event list (either produced with emproc or available as PPS product; here it has the assumed file name MOS.fits ). ... The users should note that the SAS metatask xmmselect allows them to interactively define source and background regions (via ds9) and to run backscale on the fly. ...

... 1Haynes+ A catalogue at 5 GHz of 915 sources in the Galactic plane is presented. Sources with a peak beam brightness temperature of at least 0.2 K above the surrounding background are included, except in confused regions; a point source of 0.2 K corresconds to 0.26 Jy. ... It was assumed that Hydra A was a point source with a peak flux density of 13 Jy at 5 GHz; this is equivalent to a mean beam brightness temperature of 10.0 K for a beamwidth of 4.1x4.4'. ...

... Solar flare activity is produced by the processes of accumulation and release of energy in an active region. ... In the framework of study of solar active regions, producing powerful flares the researchers from the RATAN-600 radio telescope have detected sources with features in the form of a sharp drop in the intensity of polarized radiation in various parts of the recorded frequency range (2-16GHz), sometimes changing the sign of polarization. ...

... The actual cross-correlations were done as follows: north of WGACAT was correlated with the GB6 catalog with a correlation radius of one arc minute. ... We therefore cross-correlated WGACAT with the GB6 and PMN radio catalogs with a 1.5 arcmin radius. ... As a result of this experiment, we then added to the WGACAT/PMN candidate list the 29 unclassified sources obtained from the 1.5 arcmin correlation and having PSPC offsets arcmin, ratio between X-ray/radio offset and positional error , and . ...

Next: The Model Up: No Title Previous: Radiopulsars as Sources of . In this section, we study the evolution of stellar populations on a time-scale of 10 Myr for a starburst љ occurring under conditions similar to those in the Galactic Center (see Lipunov et al. (1995d)[ 126 ]). We estimate the expected number of X-ray transient љ sources (NS + MS star), super accreting BH, and BH + supergiant binaries, all as functions of time elapsed after the burst. ...
