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…
Astro-WISE: Chaining to the Universe
Edwin A. Valentijn, John P. McFarland, Jan Snigula +18
The recent explosion of recorded digital data and its processed derivatives threatens to overwhelm researchers when analysing their experimental data or when looking up data items…
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…
Day-Scale Variability of 3C 279 and Searches for Correlations in Gamma-Ray, X-Ray, and Optical Bands
R. C. Hartman, M. Villata, T. J. Balonek +36
Light curves of 3C 279 are presented in optical (R-band), X-rays (RXTE/PCA), and gamma rays (CGRO/EGRET) for 1999 Jan-Feb and 2000 Jan-Mar. During both of those epochs the gamma-ra…
Evidence of Rapid Optical Variability In Selected Narrow-Line Seyfert 1 Galaxies
H. R. Miller, E. C. Ferrara, J. P. McFarland +3
We present the first results of a search for the presence of rapid optical variability in a sample of five Narrow-Line Seyfert 1 galaxies. We find clear evidence of rapid variabili…
