The Type II supernova SN 2023ixf, discovered by K. Itagaki in the nearby galaxy M101 on May 19, has been intensively monitored at all wavelengths (e.g., AstroNotes 2023-119, ATels #16044, #16045, #16047, #16049, #16052, #16053). In addition, the progenitor of this supernova has been searched and studied in several archival data obtained before this SN explosion: e.g., detection at the mid-IR band with Spitzer/IRAC (ATel #16042), at the optical wavelength with HST (ATel #16050), and no detection of the associated point source in the Chandra archival image (ATel #16051).
We searched the XMM-Newton archive for the progenitor of
SN 2023ixf in X-rays. There are four XMM-Newton observations (ObsIDs 0104260101, 0164560701, 0212480201, and 0824450501) at around the sky position of
SN 2023ixf (RA=14:03:38.562, DEC=+54:18:41.940). Before the SN explosion, the XMM data were obtained in 2002, 2004, 2005, and 2018 with a total exposure of 210 ks. We stacked all the X-ray images. The effective exposure of the summed image is 128 ks at the SN position. No apparent X-ray source was found at the SN position within 4 arcsec, the astrometric accuracy of EPIC (e.g., Pavan et al. AA 526,A122, 2011). Within 15 arcsec of the XMM-Newton PSF, a faint point-like X-ray source was detected by 16 arcsec apart from the SN position, but enough outside the astrometric accuracy (4 arcsec).
The extracted X-ray sky images of M101 are available in the following link. The 0.4-1.0 keV (red) and 1.0-3.0 keV (green) images are compared with the HST B-band image (blue).
