Abstract
We present a near-infrared (NIR) candidate star cluster catalog for the central kiloparsec of M82 based on new JWST NIRCam images. We identify star cluster candidates using the F250M filter, finding 1357 star cluster candidates with stellar masses >10(4)M(circle dot). Compared to previous optical catalogs, nearly all (87%) of the candidates we identify are new. The star cluster candidates have a median intrinsic cluster radius of approximate to 1 pc and stellar masses up to 10(6)M(circle dot). By comparing the color-color diagram to dust-free yggdrasil stellar population models, we estimate that the star cluster candidates have A(V) similar to 3-24 mag, corresponding to A(2.5 mu m) similar to 0.3-2.1 mag. There is still appreciable dust extinction toward these clusters into the NIR. We measure the stellar masses of the star cluster candidates, assuming ages of 0 and 8 Myr. The slope of the resulting cluster mass function is beta = 1.9 +/- 0.2, in excellent agreement with studies of star clusters in other galaxies.
