The oldest X-ray supernovae: X-ray emission from 1941C, 1959D, 1968D
Roberto Soria, Rosalba Perna
We have studied the X-ray emission from four historical Type-II supernovae (the newly-discovered 1941C in NGC 4631 and 1959D in NGC 7331; and 1968D, 1980K in NGC 6946), using Chand…
Do Ultraluminous X-Ray Sources Exist in Dwarf Galaxies?
Douglas A. Swartz, Roberto Soria, Allyn F. Tennant
A thorough search for Ultraluminous X-ray source candidates within the Local Volume is made. The search spatially matches potential ULXs detected in X-ray images or cataloged in th…
Discovery of a Transient X-ray Source in the Compact Stellar Nucleus of NGC 2403
Mihoko Yukita, Douglas A. Swartz, Roberto Soria +1
We report the discovery of an X-ray source coincident with the nuclear star cluster at the dynamical center of the nearby late-type spiral galaxy NGC 2403. The X-ray luminosity of…
