These data were acquired as part of the MOJAVE and 2 cm Survey programs, and from the VLBA archive. The sample-selection criteria are based on multi-epoch parsec-scale (VLBA) flux density, and heavily favor highly variable and compact blazars. The sample includes nearly all the most ...
Our analysis is based on new 2 cm Very Long Baseline Array (VLBA) images obtained between 2002 and 2007, but includes our previously published observations made at the same wavelength, and is supplemented by VLBA archive data. In all, we have used 2424 images spanning the years 1994-2007 ...
Additionally, we analyzed the 1612 MHz OH maser\nobservations of OH 44.8-2.3 from the VLA archive. The SiO masers of OH 44.8-2.2\nform a ring located at ~5.4 AU around the star. The masers appear to be highly\nlinearly polarized with fractional linear polarization up to 100%. The ...
Aims: We have analysed VLBA 92 cm archive data of 44 extragalactic sources in order to identify early targets and potential calibrator sources for the LOFAR radio telescope and the RadioAstron space VLBI mission. Some of these sources will also be suitable as "in-beam" calibrators, permitting ...
