The Apparent Host Galaxy of PKS 1413+135: HST, ASCA and VLBA Observations

Eric S. Perlman, John T. Stocke, Chris L. Carilli +5

PKS 1413+135 (z=0.24671) is one of very few radio-loud AGN with an apparent spiral host galaxy. Previous authors have attributed its nearly exponential infrared cutoff to heavy abs…
