Discovering High- BL Lacs Using Swift/UVOT and SARA Observations with the Dropout Technique
Y. Sheng, K. Imam, A. Kaur +14
Measuring spectroscopic redshifts for BL Lacertae (BL Lac) objects, a class of blazar, is challenging because their optical spectrum lacks, or has weak, emission lines ( equivalent…
