Sgr A* and Company -multiwavelength Observations of Sgr A* and Vla Search of " Sgr A*'s " in Liners
We report first results from a multiwavelength campaign to measure the simultaneous spectrum of Sgr A* from cm to mm wavelengths. The observations confirm that the previously detected submm-excess is not due to variability; the presence of an ultracompact component with a size of a few Schwarzschild radii is inferred. In a VLA survey of LINER galaxies, we found Sgr A*-like nuclei in one quarter...
متن کاملZeeman Observations of W Sgr*
A new precise method for measuring magnetic fields on Zeeman plates of the southern cepheid W Sgr is reviewed. Ten plates over the 7_6 period of pulsation show two extrema in the measured values of the effective magnetic field. The method has a precision of ±0.4_ in the Zeeman shift corresponding to ±50 gauss (g). A negative "spike" of -220g occurred at the time of arrival of the compressional ...
متن کاملApsidal motion in southern eccentric eclipsing binaries: YY Sgr, V523 Sgr, V1647 Sgr, V2283 Sgr and V760 Sco
Several new times of minimum light recorded with photoelectric means have been gathered for the early-type eccentric eclipsing binaries YY Sgr (P = 2. d63, e = 0.16), V523 Sgr (2. d32, 0.16), V1647 Sgr (3. d28, 0.41), V2283 Sgr (3. d47, 0.49) and V760 Sco (1. d73, 0.03). The O − C diagrams are analyzed using all reliable timings found in the literature and improved values for the elements of th...
متن کاملSAX observations of SGR 1806 – 20
Your thesaurus codes are: missing; you have not inserted them ASTRONOMY AND ASTROPHYSICS Abstract. We have observed with the BeppoSAX satellite the quiescent counterpart of the Soft Gamma-ray Repeater SGR 1806–20. Observations performed in October 1998 and in March 1999 showed that this pulsar continued its long term spin-down trend at an average rate of ∼8 10 −11 s s −1 while its flux and spec...
متن کاملGMRT Observations of Microquasar V4641 Sgr
We report the GMRT observations of V4641 Sgr during the May 2002 outburst at radio frequencies of 610 and 244 MHz. This is the lowest frequency radio detection of this source. The present low frequency radio observations clearly showed spectral evolution from the optically thick to thin state. This behavior is broadly consistent with the expanding bubble model. However, the flux densities obser...
