Broad-band (0.5-30 keV) X-ray imaging of starburst galaxies with Chandra and NuSTAR
Abstract
We request 120 ks of ACIS imaging for monitoring of the bright accreting binary populations of NGC 253 and M82, the two nearest starburst galaxies. 700 ks of NuSTAR observations, during Chandra Cycle 13, have been approved for these galaxies. We will place basic constraints on the nature of the compact objects (black holes vs neutron stars) in bright binaries, study basic scaling of hard X-ray emission with e.g., star formation rate, monitor ULX sources and search for radio/X-ray flaring events. We will also place the best constraints to date on Inverse Compton emission from starbursts. We request 48 hours of NRAO VLBA imaging for 0.2 arcsec monitoring, allowing radio flares such as observed in the HMXB Cyg X-3 to be detected in these two galaxies.
