Host galaxy subtraction of TeV candidate BL Lacertae objects
Host galaxy subtraction of TeV candidate BL Lacertae objects
Context. Photometric monitoring of active galactic nuclei is often complicated by the presence of a strong host galaxy component, which adds unwanted flux to the measurement and introduces a seeing-dependence to the flux that can plaque e.g. microvariability studies. We are currently monitoring a sample of 24 TeV candidate BL …
