... 88, Jan. 1983, p. 1-15. l. A survey of extragalactic radio sources made using driven declination scans is reported covering an area of about 0.07 sr to a limiting flux density of 35 mJy. The fast-scan survey was carried out at a galactic latitude greater than 17 deg with the NRAO 91-m telescope operating at 4.755 GHz, and the 480 sources detected were reobserved at 1.4 GHz with the National Astronomy and Ionosphere Center 305-m telescope at Arecibo. ...

... The stars examined here were primarily culled from two lists of X--ray sources in Orion. ... The second region is two degrees in extent east--west and ten degrees north--south with Orionis being near the northern edge. ... In the end, two main regions were chosen for monitoring: stars near Orionis and stars northwest of the belt of Orion. ... The PSPC identified 22 sources within 15 of Orionis in addition to the sources listed in Table 1 , giving a total of 85 X--ray sources in the Orionis region. ...

... Seminar archive . ... The structure of the X-ray sources in the hard spectral state of accreting black-hole binaries has been a subject of intense debate. The paradigm dominant for many years postulated that the accretion disc in the hard state is truncated at some radius >> the innermost stable orbit (ISCO) whereas the disc reaches the ISCO in the soft state. ... On the other hand, there have been numerous claims in recent years that the disc extends to the ISCO in the hard state. ...

... We compare our results with the GRANAT X-ray observations of the Galactic center (Churazov et al. ... It is instructive to compare our results for the Galactic center starburst with what might be expected for a continuous star formation, with the average rate characteristic for the whole Galaxy. For this continuous star formation model, we would expect to observe in the region of around the Galactic center about 10% of the total number of X-ray sources in the Galaxy. ...

Comment on J0513-2159 . Our image shows an extension to about 5 mas SE from the brightest feature. The EVN 8 GHz image by Dallacasa et al. (1998), with about five times larger resolution, shows an extension from the brightest feature roughly opposite to our direction. As noted by Dallacasa et al. (1998), the structure detected has a highly inverted spectrum, which, together with the reported variability in the source, could explain the structural disagreement. ...

... The results of long-term monitoring of Gigahertz-Peaked Spectrum sources were found the statistically significant differences (0.05 significance level) in the high-frequency spectral index distribution between subgroups of galaxies and quasars. ... This can mean that the electron energy distribution for GPS galaxies is steeper than for GPS quasars. ... The first area corresponds to GPS-quasars that have statistically larger value of redfhift, second area corresponds to GPS-galaxies. ...
