The Unusual Broadband X-ray Spectral Variability of NGC 1313 X-1 seen with XMMNewton, Chandra and NuSTAR
D. J. Walton, C. Pinto, M. Nowak +19
We present results from the major coordinated X-ray observing program on the ULX NGC 1313 X-1 performed in 2017, combining -, and , focusing on the e…
The Hunt for Pulsating Ultraluminous X-ray Sources
X. Song, D. J. Walton, G. B. Lansbury +4
Motivated by the recent discoveries that six Ultraluminous X-ray Sources (ULXs) are powered by highly super-Eddington X-ray pulsars, we searched for additional pulsating ULX (PULX)…
Discovery of a red supergiant donor star in SN2010da/NGC 300 ULX-1
M. Heida, R. M. Lau, B. Davies +7
SN2010da/NGC 300 ULX-1 was first detected as a supernova impostor in May 2010 and was recently discovered to be a pulsating ultraluminous X-ray source. In this letter, we present V…
Discovery of a 2.8 s pulsar in a 2 d orbit High-Mass X-ray Binary powering the Ultraluminous X-ray source ULX-7 in M51
G. A. Rodríguez Castillo, G. L. Israel, A. Belfiore +26
We discovered 2.8 s pulsations in the X-ray emission of the ultraluminous X-ray source (ULX) M51 ULX-7 within the UNSEeN project, which was designed to hunt for new pulsating ULXs…
Hot Dust-Obscured Galaxies with Excess Blue Light
R. J. Assef, M. Brightman, D. J. Walton +10
Hot Dust-Obscured Galaxies (Hot DOGs) are among the most luminous galaxies in the Universe. Powered by highly obscured, possibly Compton-thick, active galactic nuclei (AGNs), Hot D…
A Low-Flux State in IRAS 00521-7054 seen with NuSTAR and XMM-Newton: Relativistic Reflection and an Ultrafast Outflow
D. J. Walton, E. Nardini, L. C. Gallo +8
We present results from a deep, coordinated -+ observation of the Seyfert 2 galaxy IRAS 00521-7054. The data provide the first detection of this sourc…
