1. Radio survey for new compact HII regions
... 227Wink This paper containes an investigation of 91 sources which appear to be point sources when observed with the angular resolution of the 100-m telescope at 4.9 GHz, teta_a = 2.6', and which we expected to be HII regions. The basic search list was prepared from the 4.9 GHz survey of the galactic plane by Altenhoff et al. ... In the present paper we list 4.9 GHz flux densities only for sources for sources for which we present new observations. ... source structure indicated . ...

2. Regions and Source Parameters
... This section will deal with obtaining photons within specified regions of an image. Available regions are: Annulus Box Circle Ellipse Field -- entire field Irregular region based on intensity of map... i.e. region defined by contour levels. ... The imcnts task in the xray-spatial package sums the source and background counts in specified regions, and subtracts one from the other properly normalized. ... imcnts* - Find counts in an extended region, after removing an embedded point source . ...

3. News Results
This source is hiding behind our Galaxy at a distance of ~18 Mpc, located at a galactic latitide of 0 degrees. ... As we look towards longer wavelengths, 60 micron, to try and penetrate the Galactic Plane, we still see confusion from galactic sources. ... If the image seems some what confusing that is because the MOST is a continuum radio telescope and when it looks in the direction of our Galaxy it detects radiation from sources within our Galaxy and from sources that may lie behind our Galaxy. ...

4. The Cross-correlations
... 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 . ...

5. NIR Inages of H2O Masers (Abstract)
... We present the first results of an extensive near infrared survey of galactic and OH masers in high--luminosity star forming regions (SFR) aimed to see if there are near--infrared (NIR) sources directly associated with the masers. ... Although not in all sources there are high sensitivity--high resolution radio continuum observations, only few of the K--band/maser sources are closely associated with known ultracompact (UC) Hii regions. ...

Neutral hydrogen distribution in the region of radio source Cygnus X . ... HI distribution in the region of radio source Cygnus X and supernova remnant G78.2+2.1 has been investigated from observations in 21 cm radio line using radio telescope RATAN-600. ... The existance of the large HI shell and a cavity in molecular gas distribution around Cygnus X indicates this radio source most probably to represent a united structure and whole gas may be drived by stellar wind of Cyg OB2 stellar assotiation. ...

7. Energy Sources of the Far-Infrared Emission of M33
We present observations of the spiral galaxy M33 with Spitzer at 24, 70, and 160 ЮМm. ... We compare the morphology of M33 at far-infrared wavelengths with other standard SF indicators such as HЮБ and radio continuum using a Fourier filtering technique to separate the diffuse emission components from compact sources. We find that the infrared emission at 24 and 70 ЮМm follows closely the structure of the ionized gas, indicating that it is heated largely by hot, ionizing stars. ... citations = 45 . ...

8. Detection of polarized radiation sources with unusual spectral characteristics
... 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. ...

... Armagh Observatory, College Hill, Armagh BT61 9DG, +44 (0)28 3752 2928 . ... Quasi-stationary electron distributions for the different values of the particle escape time. ... The electron-cyclotron maser instability is widespread in the Universe, producing, e.g., radio emission of the magnetized planets and cool substellar objects. ... The model used takes into account the radiation escape from the source region a
