The Millimeter-Radio Emission of BL Lacertae During Two gamma-ray Outbursts

Dae-Won Kim, Sascha Trippe, Sang-Sung Lee +13

We present a study of the inexplicit connection between radio jet activity and gamma-ray emission of BL Lacertae (BL Lac; 2200+420). We analyze the long-term millimeter activity of…
