Correlated Multi-Waveband Variability in the Blazar 3C~279 from 1996 to 2007
R. Chatterjee, S. G. Jorstad, A. P. Marscher +12
We present the results of extensive multi-waveband monitoring of the blazar 3C~279 between 1996 and 2007 at X-ray energies (2-10 keV), optical R band, and 14.5 GHz, as well as imag…
New Multiwavelength Observations of PKS 2155-304 and Implications for the Coordinated Variability Patterns of Blazars
M. Angela Osterman, H. Richard Miller, Kevin Marshall +4
The TeV blazar PKS 2155--304 was the subject of an intensive 2 week optical and near-infrared observing campaign in 2004 August with the CTIO 0.9m telescope. During this time, simu…
Multiwavelength Observations of the Extreme X-Ray Selected BL Lac Object PG 1553+11 (1ES 1553+113)
M. Angela Osterman, H. Richard Miller, Amy M. Campbell +9
PG 1553+11 was the target of a coordinated three week multiwavelength campaign during 2003 April and May. A significant X-ray flare was observed during the second half of this camp…
X-ray/Optical Variability of Akn 120 and 3C 120
K. Marshall, E. C. Ferrara, H. R. Miller +2
Using the Rossi X-ray Timing Experiment (RXTE), we have observed both the Seyfert 1 galaxy Akn 120 and the broad-line radio galaxy 3C 120. Monitoring observations spanning 2 years…
Coordinated Multiwavelength Observations of BL Lacertae in 2000
M. Boettcher
BL Lacertae was the target of an extensive multiwavelength monitoring campaign in the second half of 2000. Simultaneous or quasi-simultaneous observations were taken at radio (UMRA…
Synchrotron and Inverse Compton Variability in the BL Lacertae object S5 0716+714
P. Giommi, E. Massaro, L. Chiappetti +14
We report intensity variations of different spectral components in the BL Lac object S5 0716+714 detected during coordinated BeppoSAX and optical observations in 1996 and 1998. The…
