We present evolutionary synthesis modeling of the nuclear regions of the starburst galaxy M 82, based on near-infrared integral field spectroscopy and mid-infrared ISO spectroscopy. Our data indicate the occurrence of two distinct starburst episodes in the central 500 pc about 8 – 15 Myr and 5 Myr ago, each lasting a few million years only. The first burst was most intense within 50 pc of the nucleus while the second burst took place in a circumnuclear ring of radius ~ 85 pc and along the stellar bar at larger radii. These recent episodes succeeded earlier starburst activity ~ 1 kpc away from the nucleus and peaking 650 Myr ago, as traced by the luminous star clusters studied by de Grijs et al. (2001). The combined results of both studies reveal complex evolution of starburst activity in M 82 which is consistent with a tidally-induced bar-driven scenario.

AbstractIntegral field spectroscopy of nearby supernova sites within ~30 Mpc have been obtained using multiple IFU spectrographs in Hawaii and Chile. This technique enables both spatial and spectral information of the explosion sites to be acquired simultaneously, thus providing the identification of the parent stellar population of the supernova progenitor and the estimates for its physical parameters including age and metallicity via the spectrum. While this work has mainly been done in the optical wavelengths using instruments such as VIMOS, GMOS, and MUSE, a near-infrared approach has also been carried out using the AO-assisted SINFONI. By studying the supernova parent stellar population, we aim to characterize the mass and metallicity of the progenitors of different types of supernovae.
