Spectral Evolution of a Luminous Compact X-Ray Source in NGC 253 with Chandra and XMM-Newton

Publ.Astron.Soc.Jap. 57 (2005) 507 Spectral studies of a luminous X-ray source, NGC 253 X21, are presented based on archival Chandra and XMM-Newton data. The Chandra observation on 1999 December 16 detected the source at a bolometric luminosity of 0.3 x 10^39 erg/s (assuming isotropic emission), whi...
