XRISM XTEND observation 201085010

Title

X-RAY SPECTROSCOPY OF 30 DORADUS

Abstract

30 Doradus represents the most intense starburst in the Local Group of galaxies and powers the spectacular Tarantula Nebula, although the underlying astrophysics remains poorly understood. We propose an XRISM observation to perform the first X-ray spectroscopic study of the starburst region. We will determine the thermal and dynamical states of the massive stellar cluster wind that shapes the nebula, the X-ray contribution from the charge exchange between hot and cool gases, and the presence of the non-thermal X-ray component and hence the cosmic ray acceleration in the region. This study will help us to understand how the starburst feedback works.
