The long-term variability of a population of ULXs monitored by Chandra

Hannah P. Earnshaw, Gauri Patti, Murray Brightman +5

We present preliminary results of a Chandra Large Program to monitor the ultraluminous X-ray source (ULX) populations of three nearby, ULX-rich galaxies over the course of a year,…

Sharp Periodic Flares and Long-Term Variability in the High-Mass X-ray Binary XTE J1829-098 from RXTE PCA, Swift BAT and MAXI Observations

Robin H. D. Corbet, Ralf Ballhausen, Peter A. Becker +20

XTE J1829-098 is a transient X-ray pulsar with a period of ~7.8 s. It is a candidate Be star system, although the evidence for this is not yet definitive. We investigated the twent…

Accreting on the edge: a luminosity-dependent cyclotron line in the Be/X-ray Binary 2S 1553-542 accompanied by accretion regimes transition

Christian Malacaria, Yash Bhargava, Joel B. Coley +15

Accreting X-ray pulsars (XRPs) undergo luminous X-ray outbursts during which the luminosity-dependent spectral and timing features of the neutron star's emission can be analyzed in…

The stellar and wind parameters of six prototypical HMXBs and their evolutionary status

R. Hainich, L. M. Oskinova, J. M. Torrejón +7

High-mass X-ray binaries (HMXBs) are exceptional astrophysical laboratories that offer a rare glimpse into the physical processes that govern accretion on compact objects, massive-…

XMM-Newton Campaign On Ultraluminous X-ray Source NGC 1313 X-1: Wind vs. State Variability

C. Pinto, D. J. Walton, E. Kara +12

Most ultraluminous X-ray sources (ULXs) are thought to be powered by neutron stars and black holes accreting beyond the Eddington limit. If the compact object is a black hole or a…

The discovery of weak coherent pulsations in the ultraluminous X-ray source NGC 1313 X-2

R. Sathyaprakash, T. P. Roberts, D. J. Walton +8

We report the detection of weak pulsations from the archetypal ultraluminous X-ray source (ULX) NGC 1313 X-2. Acceleration searches reveal sinusoidal pulsations in segments of two…
