The Disk-Corona Model and Mass Estimates of the Ultraluminous X-ray Source Holmberg IX X-1

Ramandeep Gill, Eda Sonbas, Kalvir S. Dhuga +1

The origin of the variable X-ray emission in the keV energy range of ultraluminous X-ray sources (ULXs) remains unclear, making it difficult to constrain the mass of th…

Rapid Spectral Variability of a Giant Flare from a Magnetar in NGC 253

O. J. Roberts, P. Veres, M. G. Baring +18

Magnetars are slowly-rotating neutron stars with extremely strong magnetic fields ( G), episodically emitting ms long X-ray bursts with energies of $\sim10^{4…
