Although a few astrophysical explanations have been put forward, they are totally ad hoc. We show that a natural explanation emerges within the conventional models of FSRQs provided that photon-ALP oscillations take place inside the source for the model parameters within an allowed range.}, month = {Jun}, date = {2013-06-24}, organization = {9th Patras Workshop on Axions, WIMPs and WISPs, Mainz (Germany), 24 Jun 2013 - 28 Jun 2013}, keywords = {Hypothetisches Teilchen (gnd)}, cin = {L}, cid = {I:(DE-H253)L-20120731}, pnm = {899 - ohne Topic (POF3-899)}, pid = {G:(DE-HGF)POF3-899}, experiment = {EXP:(DE-MLZ)NOSPEC-20140101}, typ = {PUB:(DE-HGF)29 / PUB:(DE-HGF)8 / PUB:(DE-HGF)7}, doi = {10.3204/DESY-PROC-2013-04/roncadelli_marco}, url = {https://bib-pubdb1.desy.de/record/408339}, }
