Cluster Multi-spacecraft Determination of AKR Angular Beaming
R. L. Mutel, I. W. Christopher, J. S. Pickett
Simultaneous observations of AKR emission using the four-spacecraft Cluster array were used to make the first direct measurements of the angular beaming patterns of individual burs…
Striated AKR Emission: A Remote Tracer of Ion Solitary Structures
R. L. Mutel, J. D. Menietti, I. W. Christopher +2
We describe the statistical properties of narrowband drifting auroral kilometric radiation ('striated' AKR) based on observations from the Cluster wideband receiver during 2002-200…
Structure and flux variability in the VLBI jet of BL Lacertae during the WEBT campaigns (1995--2004)
U. Bach, M. Villata, C. M. Raiteri +9
BL Lacertae has been the target of several observing campaigns by the Whole Earth Blazar Telescope (WEBT) collaboration and is one of the best studied blazars at all accessible wav…
Is the Radio Core of BL Lac Precessing?
R. L. Mutel, G. R. Denn
Stirling et al. (2003) reported the discovery of a 2.3 year periodic variation in the structural position angle of the parsec-scale radio core of the blazar BL Lac. We searched for…
Comment on "Detection of small comets with a ground-based telescope" by Frank and Sigwarth
R. L. Mutel, J. D. Fix
Frank and Sigwarth (2001,JGRSP,106,A3,3665; FS) report on an optical search for small comets in which they report detection of nine faint trails. FS claim that these trails are pro…
Locations of Auroral Kilometric Radiation Bursts Inferred From Multi-Spacecraft Wideband Cluster VLBI Observations i: Description of Technique and Initial Results
R. L. Mutel, D. A. Gurnett, I. W. Christopher +2
The Cluster Wideband Data instrument has been used to determine the locations of auroral kilometric radiation (AKR) using very long baseline interferometry. The technique involves…
