As a natural explanation, the DARMA scenario has previously been proposed, wherein photons can oscillate into a new very light axionlike particle and vice-versa in the presence of cosmic magnetic fields. Here we demonstrate that the most recent observations further support the DARMA scenario, thereby making the existence of a very light axion-like particle more likely.}, month = {Jul}, date = {2010-07-05}, organization = {6th Patras Workshop on Axions, WIMPs and WISPs, Zürich (Switzerland), 5 Jul 2010 - 9 Jul 2010}, keywords = {blazar: spectrum (INSPIRE) / axion (INSPIRE) / Cherenkov counter (INSPIRE) / magnetic field (INSPIRE) / gamma ray (INSPIRE) / imaging (INSPIRE) / VERITAS (INSPIRE) / MAGIC (INSPIRE) / WIMP (INSPIRE) / WISP (INSPIRE) / HESS (INSPIRE)}, cin = {L}, cid = {I:(DE-H253)L-20120731}, pnm = {899 - ohne Topic (POF3-899)}, pid = {G:(DE-HGF)POF3-899}, experiment = {EXP:(DE-H253)HERA(machine)-20150101}, typ = {PUB:(DE-HGF)8 / PUB:(DE-HGF)15}, eprint = {1102.1177}, howpublished = {arXiv:1102.1177}, archivePrefix = {arXiv}, SLACcitation = {$\%\%CITATION$ = $arXiv:1102.1177;\%\%$}, doi = {10.3204/DESY-PROC-2010-03/roncadelli_marco}, url = {https://bib-pubdb1.desy.de/record/296200}, }
