... Three day radio-astronomical forecast of the proton activity of the Sun: The figure shows multiwave radio emission scans - graphs of the distribution of intensity I and circular polarization V across the solar disk, obtained at RATAN-600. ... According to this criterion, for a proton flare to arise, the flux of radio emission must be sufficiently high at short wavelengths (blue color scans) and should increase with time compared to the general intensity. ... More about the solar activity . ...

We derive the distribution of the synchrotron spectral index across NGC 6946 and investigate the correlation between the radio continuum (synchrotron) and far-infrared (FIR) emission using the KINGFISH Herschel-PACS and SPIRE data. The radio-FIR correlation is studied as a function of star formation rate, magnetic field strength, radiation field strength, and the total gas surface density. ... The synchrotron-FIR correlation suggests a coupling between the magnetic field and the gas density. ...

We present radio interferometric observations of the Algol-type binary system V505 Sagitarii made with the ATNF Compact Array at 6 cm and 3.6 cm over one orbital cycle (1.18 days). We obtained a strong detection of the source (1.5 mJy at 6 cm and 1.4 mJy at 3.6 cm). The radio flux level shows a clear modulation with evidence of eclipses of the emission region at both conjunctions of the binary which may indicate the existence of an intra-binary region of activity. ...

Presented on Tuesday, January 7, 2003 . We construct a detailed longitude-velocity diagram through the actual midplane of the Galactic H I disk. The Galactic midplane definition is based on single-dish sky surveys, and the detailed l-v slice ( Fig. 1 ) is extracted from the Canadian Galactic Plane Survey ( CGPS ; Taylor et al. 2003 ). ... Note: other slices offset from this one were not shown in the AAS poster for lack of space, but they are available here . ...
