Abstract

We present evidence for the rapid variability of the high-velocity iron K-shell absorption in the nearby (z = 0.184) quasar PDS 456. From a recent long Suzaku observation in 2013 (~1 Ms effective duration), we find that the equivalent width of iron K absorption increases by a factor of ~5 during the observation, increasing from <105 eV within the first 100 ks of the observation, toward a maximum depth of ~500 eV near the end. The implied outflow velocity of ~0.25 c is consistent with that claimed from earlier (2007, 2011) Suzaku observations. The absorption varies on timescales as short as ~1 week. We show that this variability can be equally well attributed to either (1) an increase in column density, plausibly associated with a clumpy tim...
