PKS 1413+135 (/NICMOS data require the AGN to be decentered relative to the optical galaxy by 13 ± 4 mas. This could be interpreted as suggestive of an AGN location far in the background compared with the optical galaxy, but it can also be explained by obscuration and/or nuclear structu...
quasar HB89 1413+135 (1.5 Jy at 103 GHz; 14h13m33.92s +13o:34′17.51′′ [B1950.0]) was observed every 25 minutes to monitor phase and gain variations, and 3C 273 and 3C 454.3 were observed to determine the passband structure. ...
The IR excess could arise from a BL LAC type nucleus with a steep non-thermal spectrum (α 4.5 defined by F α v α ), similar to the recently identified 'red QSOs' typified by 1413 + 135 (refs 1, 2).关键词: Experimental/ astronomical spectra BL Lac-type objects galactic nuclei ...
PKS 1413+135 (z = 0.24671) is one of very few radio-loud active galactic nuclei (AGNs) with an apparent spiral host galaxy. Previous authors have attributed its nearly exponential infrared cutoff to heavy absorption but have been unable to place tight limits on the absorber or its location ...
