EDGE-ON DISK OR RELATIVISTIC WIND THE CASE OF PG 1402+261

We propose a simultaneous observation with NuSTAR (150 ks) and XMM (75 ks) ofthe radioquiet NarrowLine Seyfert 1 galaxy PG 1402+261 (z0.164), which showedsignificant spectral complexity at 69 keV in a previous XMM snapshot. This canbe interpreted as either a very strong, extremely broadened FeK emission linefrom the accretion disk, or the signature of a highcolumn, highionization diskwind. By pinpointing the intensity and shape of the continuum beyond thispuzzling feature, NuSTAR will allow us to distinguish between the two scenariosor disentangle their relative contribution. Indeed, PG 1402+261 is ahighluminosity (and possibly more extreme) equivalent of other NLS1s where bothstrong reflection and ultrafast outflows have been recently revealed. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
