The disappearance of the progenitor of SN 2012aw in late-time imaging
  We present new late-time near-infrared imaging of the site of the nearby
core-collapse supernova SN 2012aw, confirming the disappearance of the point
source identified by Fraser et al. (2012) and Van Dyk et al. (2012) as a
candidate progenitor in both J and Ks filters. We re-measure the progenitor
photometry, and find that both the J and Ks magnitudes of the source are
consistent with those quoted in the literature. We also recover a marginal
detection of the progenitor in H-band, for which we measure H=19.67+/-0.40 mag.
Comparing the luminosity of the progenitor to stellar evolutionary models, SN
2012aw appears to have resulted from the explosion of a 12.5+/-1.5 Msun red
supergiant.
