Cyg X-3 . We carried out a monitoring program to study the flare variability of the radio emission of X-ray sources. ... After this flare, there was a sharp decrease in the radio intensity on May 29--31, to 15--20 mJy at 4--11 GHz, 10--12 days before a powerful flare on June 12 (~4 Jy). ... We found the signifficant correlation of the radio flux and hard X-ray (BATSE data) radiation and anti-correlation of the radio flux and soft X-ray (RXTE ASM data) radiation during the powerful flare. ...

... Flaring events were detected when the fluxes increased by a factor of 2-200. ... Radio flaring events of SS433, Cyg X-3, LSI+61d303 were often optically thin at >5 GHz, and follow to general predictions of the relativistic outflows of mass or fast electrons from binaries. ... After 18 days of the quenched state (10 mJy) Cyg X-3 exhibited the 1Jy- radio flare on 1 Feb 2006. ... At last on 25 July we have detected a very p owerful flare (15 Jy) from Cyg X-3 again. ...

K-band Arcetri Obscured Supernova Search . What is the KAOSS Project? W hat is the KAOSS Project? Some recent surveys aimed at detecting Supernovae (SNe) in the optical have found that starburst galaxies do not show evidence for an enhanced SN rate, with respect to quiescent galaxies (Richmond et al. ... A similar result was obtained by Navasardyan et al. (2001) who looked for SNe in interacting galaxies, finding no evidence for correlations between SN rate and galaxy properties. ...

We present photometric observations of six radio-loud quasars that were detected by the COMPTEL gamma-ray telescope. ... Two sources are as blue as optically-selected quasars, and are likely to be dominated by the accretion disc emission, while three others show colours consistent with a red synchrotron component. We discuss the properties of the COMPTEL sample of quasars, as well as the implications our observations have for multiwavelength modelling of gamma-ray quasars. | ... Australia . ...

We describe multi-wavelength, simultaneous observations of the RS CVn star, II Pegasi, most of which were obtained during the first three weeks of September 1992. These observations were made using optical and infra-red broad-band photometry, ultraviolet and optical spectroscopy and microwave monitoring. ... One of the flares, observed in optical photometry and ultraviolet spectroscopy is one of the most energetic ever observed on this star. ...

The properties of the midplanes of planet-forming protostellar disks remain largely unprobed by observations due to the high optical depth of dust and commonly observed molecules. However, rotational emission lines from rare molecules may have optical depths near unity in the vertical direction, so that the lines are strong enough to be detected, yet remain transparent enough to trace the disk midplane. In this talk, I will present a chemical evolution model of an MRI-active T-Tauri disk. ...
