Ultraviolet, optical, and radio observations of the transient X-ray source GRO J0422+32

AIP Conference Proceedings, 1993
We have monitored the early evolution of the transient X‐ray source GRO J0422+32 from approximately 2 weeks post‐discovery and into its early decline phase at ultraviolet, optical and radio wavelengths. Optical and ultraviolet spectra, obtained with the Perkins 1.8‐m telescope and with IUE respectively, exhibit numerous, but relatively weak, high ...

Monte Carlo simultaneous localization of multiple unknown transient radio sources using a mobile robot with a directional antenna

2009 IEEE International Conference on Robotics and Automation, 2009
We report our system and algorithm developments that enable a single mobile robot equipped with a directional antenna to simultaneously localize multiple unknown transient radio sources. Due to signal source anonymity, short transmission durations, and dynamic transmission patterns, the robot cannot treat the radio sources as continuous radio beacons ...

Discovery of a new transient radio source in the central region of M82

2009
We report the discovery of a new compact transient radio source in the central region of the starburst galaxy M82 with MERLIN at 4994MHz. The position measured for the transient source is (J2000) 09 55 52.5083, +69 40 45.420, with an astrometric error of 5mas in each coordinate.
