[79.05] Multi-wavelength Investigation of the Variability of the Blazars PKS 1510-089, PKS 1514-241, PKS 1622-297, and PKS 2155-304

J.P. McFarland, H.R. Miller (Georgia State University)

The 4 southern sky blazars, PKS 1510-089, PKS 1514-241, PKS 1622-297, and PKS 2155-304, were monitored for approximately 6 months in 6 wavebands (B, V, R, J, H, K) every three days. These data were obtained via the SMARTS consortium on the 1.3m telescope at Cerro Tololo Interamerican Observatory. We present this data as a function of time and waveband. These variations place severe limits on the size of the emitting region, and provide constraints for the physical processes responsible for these variations. JPM is a SMARTS Fellow and JPM and HRM are grateful for support of a grant from the Research Corporation and the PEGA-RPE program at Georgia State University.
