The nucleus of M82 at radio and X-ray bands - Discovery of a new radio population of supernova candidates
Abstract
Detailed VLA radio maps are presented of the continuum radio emission in M82 and the X-ray emission from the HRI of the Einstein X-ray satellite. The authors have discovered more than 40 new radio sources within 300 pc of M82's nucleus. It is argued that nearly all of these sources are radio supernovae or supernova remnants and their radio luminosity distribution is derived. X-ray maps, both from reprocessed Einstein data and from EXOSAT reveal that most of the X-ray emission does not come from the radio/IR complex, but rather from the inner filamentary region seen in Hα and [O II] λ3727 photographs. Its distribution is perpendicular to the stellar distribution in M82. A discussion of the apparent correlation between radio continuum and far-infrared luminosities in "starburst" galaxies is included.

“The energetics of the optical filaments and X-ray gas suggests that the wind is being driven by SN explosions at the central star-forming region of M82 (Watson et al. 1984; Kronberg et al. 1985; Strickland et al. 1997, 2004; Lopez et al. 2020).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
