A grid of evolutionary synthesis models for different scenarios (initial mass function slope, metallicity, age, etc.) and computing a set of observables in a...
Multiwavelength Correlations in V404 Cyg in Quiescence
We report simultaneous X-ray, optical, and radio observations of V404 Cyg in quiescence. The X-ray flux varied dramatically by a factor of >20 during a 60 ks...
Multiwavelength Follow-up of X-ray Selected Symbiotic Candidates in the Galactic Bulge
We describe the results of an ongoing survey of X-ray selected symbiotics in the Galactic bulge, begun with the Galactic Bulge Survey and now extended to the...
Multiwavelength Observations Of Comet 67p/Churyumov-Gerasimenko During Its Approach To Perihelion
Comet 67P, the target of Rosetta mission, was observed in the visible and near-IR spectral regions during its perihelion approach. The observations were...
Multiwavelength observations of the February 1996 high-energy flare in the blazar 3C 279
We report CGRO, RXTE, ASCA, ROSAT, IUE, HST and ground-based observations of a large flare in 3C 279 in February 1996. X-rays and γ-rays peaked simultaneously...
Multiwavelength Observations of the Microquasar GRS1915+105 in May-September 1997
We present multiwavelength monitoring of the Galactic microquasar GRS1915+105 in the infrared, X-ray, and radio bands using observations from the Whipple...
On March 2 06:00 UT the transient source XTE J1859+226 had faded considerably to R=18.0 in the optical (IAC) and to a flux of about 13 mCrab (RXTE ASM). However...
