VLBA Observations and Effelsberg Monitoring of a Flaring Water Maser in Mrk 348

We report on single-dish monitoring as well as extremely high angular resolution observations of the flaring H2O maser in the Seyfert 2 galaxy Mrk 348. The H2O line is redshifted by ∼130 km s −1 with respect to the systemic velocity, is very broad, with a FWHM of 130 km s, and has no detectable high velocity components within 1500 km s on either side of the strong line. Monitoring observations ...

Mid-Infrared observations of GRS 1915+105 during plateau and flaring states

We present mid-infrared (4–18μm) observations of the microquasar GRS 1915+105 obtained with ISOCAM, the camera on board the Infrared Space Observatory (ISO), in 1996 April and 1997 October. The first observation probably occurred during a flaring event with oscillating synchrotron emission. The 1997 observation occurred a few days before a major relativistic ejection, during a plateau state of ...

Maser Observations of Planetary Nebulae Precursors

We present OH maser observations at 1612, 1665, 1667, and 1720 MHz for 86 post-asymptotic giant branch (post-AGB) stars selected from a survey of 1612 MHz maser sources in the Galactic Plane. The observations were taken with the Parkes Telescope and the Australia Telescope Compact Array between 2002 September and 2003 August. Post-AGB stars are the precursors to planetary nebulae, the diverse m...

Multi-Wavelength Observations of 1ES1959+650 in a Flaring State

In May 2002, the BL Lacertae object (BL Lac), 1ES1959+650, was detected in the Very High Energy (VHE) regime by the VERITAS collaboration using the Whipple γ-ray observatory. During the following two months, the VERITAS collaboration observed episodes of flaring; at times, the nightly average VHE signal was three times as bright as the Crab Nebula, the standard candle in VHE astronomy. 1ES1959+...
