We use natural seeing imaging of SN 2013ej in M74 to identify a progenitor candidate in archival Hubble Space Telescope (HST) + Advanced Camera for Survey images. We find a source coincident with the supernova (SN) in the F814W filter within the total 75 mas (∼3 pc astrometric uncertainty; however, the position of the progenitor candidate in contemporaneous F435W and F555W filters is significantly offset. We conclude that the ‘progenitor candidate’ is in fact two physically unrelated sources; a… Expand

Probing the final-stage progenitor evolution for Type IIP Supernova 2017eaw in NGC 6946
We presented a detailed analysis of progenitor properties of type IIP supernova 2017eaw in NGC 6946, based on the pre-explosion images and early-time observations obtained immediately after theExpand
The dusty progenitor star of the Type II supernova 2017eaw
We present pre-explosion photometry of the likely progenitor star of the Type II supernova (SN II) 2017eaw in NGC 6946. We use a Hubble Space Telescope (HST) image of SN 2017eaw to perform relativeExpand
Supernova progenitors, their variability and the Type IIP Supernova ASASSN-16fq in M66
We identify a pre-explosion counterpart to the nearby Type IIP supernova ASASSN-16fq (SN 2016cok) in archival Hubble Space Telescope data. The source appears to be a blend of several stars thatExpand
The initial masses of the red supergiant progenitors to Type II supernovae
There are a growing number of nearby SNe for which the progenitor star is detected in archival pre-explosion imaging. From these images it is possible to measure the progenitor's brightness a fewExpand
The resolved stellar populations around 12 Type IIP supernovae
Core-collapse supernovae are found in regions associated with recent massive star formation. The stellar population observed around the location of a SN can be used as a probe of the origins of theExpand

TLDR
The direct identification of SN progenitors in existing pre-explosion images, particularly those obtained through serendipitous imaging of nearby galaxies by the Hubble Space Telescope are described. Expand
The direct identification of core-collapse supernova progenitors
To place core-collapse supernovae (SNe) in context with the evolution of massive stars, it is necessary to determine their stellar origins. I describe the direct identification of SN progenitors inExpand
The radial distribution of supernovae compared to star formation tracers
Given the limited availability of direct evidence (pre-explosion observations) for supernova (SN) progenitors, the location of supernovae (SNe) within their host galaxies can be used to set limits onExpand

TLDR
It is reported that the previously proposed object was indeed the progenitor star of SN 2005gl, likely a luminous blue variable that standard stellar evolution predicts should not have exploded in that state. Expand
