Understanding the General Feature of Microvariability in Blazar W2R 192642

Mahito Sasada, Shin Mineshige, Shinya Yamada +1

We analyze the monitoring light curve of a blazar W2R 192642 to examine features of microvariability by means of the "shot analysis" technique. We select 195 intr…

"Orphan" -ray Flares and Stationary Sheaths of Blazar Jets

Nicholas R. MacDonald, Svetlana G. Jorstad, Alan P. Marscher

Blazars exhibit flares across the entire electromagnetic spectrum. Many -ray flares are highly correlated with flares detected at longer wavelengths; however, a small subset app…
