Query: AstroSat view of the NLS1 galaxy Mrk 335   We present the results from the multi-wavelength monitoring observations of
the Narrow-Line Seyfert 1 galaxy Mrk 335 with AstroSat. We analysed both the
X-ray (SXT & LAXPC) and UV (UVIT) data of the source at two epochs, separated
by ~18 days. The source was in a low flux state during the observations, and
the X-ray spectra were found to be harder than usual. The presence of soft
X-ray excess was identified in the observations, and the broadband X-ray
continuum was modelled with power-law and blackbody (modified by intrinsic
absorption) and a distant neutral reflection component. We did not find any
variability in the X-ray spectral shape or the flux over this period. However,
the UV flux is found to be variable between the observations. The obtained
results from the X-ray analysis point to a scenario where the primary emission
is suppressed and the component due to distant reflection dominates the
observed spectrum.
