First-Epoch Vlba Imaging Of 20 New Tev Blazars, B. Glenn Piner, Philip G. Edwards
Physics
We present Very Long Baseline Array (VLBA) images of 20 TeV blazars not previously well studied on the parsec scale. All 20 of these sources are high-frequency peaked BL Lac objects (HBLs). Observations were made between August and December of 2013 at a frequency of 8.4 GHz. These observations represent the first epoch of a VLBA monitoring campaign on these blazars, and they significantly increase the fraction of TeV HBLs studied with high-resolution imaging. The peak very long baseline interferometry (VLBI) flux densities of these sources range from ~10 to ~100 mJy bm–1, and parsec-scale jet structure is detected in …
