Discovery of slow X-ray pulsations in the high-mass X-ray binary 4U 2206+54
P. Reig, J. M Torrejon, I. Negueruela +3
The source 4U 2206+54 is one of the most enigmatic high-mass X-ray binaries. In spite of intensive searches, X-ray pulsations have not been detected in the time range 0.001-1000 s.…
The X-ray variability and the near-IR to X-ray spectral energy distribution of four low luminosity Seyfert 1 galaxies
I. E. Papadakis, Z. Ioannou, W. Brinkmann +1
We present the results from a study of the X-ray variability and the near-IR to X-ray spectral energy distribution of four low-luminosity, Seyfert 1 galaxies. We compared their var…
New XMM-Newton analysis of three bright X-ray sources in M31 globular clusters, including a new black hole candidate
R. Barnard, H. Stiele, D. Hatzidimitriou +6
We present detailed analysis of three globular cluster X-ray sources in the XMM-Newton extended survey of M31. The X-ray counterpart to the M31 globular cluster Bo 45 (XBo 45) was…
Rapid spectral and timing variability of Be/X-ray binaries during type II outbursts
P. Reig
We have investigated the spectral and timing variability of four accreting X-ray pulsars with Be-type companions during major X-ray outbursts. Different spectral states were define…
A jet model for Galactic black-hole X-ray sources: Some constraining correlations
N. D. Kylafis, I. E. Papadakis, P. Reig +2
Some recent observational results impose significant constraints on all the models that have been proposed to explain the Galactic black-hole X-ray sources in the hard state. In pa…
The very massive X-ray bright binary system Wack 2134 (= WR 21a)
V. S. Niemela, R. C. Gamen, R. H. Barba +5
From the radial velocities of the N IV 4058 and He II 4686 emission lines, and the N V 4604-20 absorption lines, determined in digital spectra, we report the discovery that the X-r…
