A blurred reflection interpretation for the intermediate flux state in Mrk 335. (arXiv:1210.0855v1 [astro-ph.HE]):
As part of a long term monitoring campaign of Mrk 335, deep XMM-Newton
observations catch the narrow-line Seyfert 1 galaxy (NLS1) in a complex,
intermediate flux interval as the active galaxy is transiting from low- to
high-flux. Other works on these same data examined the general behaviour of the
NLS1 (Grupe et al.) and the conditions of its warm absorber (Longinotti et
al.). The analysis presented here demonstrates the X-ray continuum and timing
properties can be described in a self-consistent manner adopting a blurred
reflection model with no need to invoke partial covering. The rapid spectral
variability appears to be driven by changes in the shape of the primary emitter
that is illuminating the inner accretion disc around a rapidly spinning black
hole (a > 0.7). While light bending is certainly prominent, the rather constant
emissivity profile and break radius obtained in our spectral fitting suggest
that the blurring parameters are not changing as would be expected if the
primary source is varying its distance from the disc. Instead changes could be
intrinsic to the power law component. One possibility is that material in an
unresolved jet above the disc falls to combine with material at the base of the
jet producing the changes in the primary emitter (spectral slope and flux)
without changing its distance from the disc.
