Further evidence for the presence of a neutron star in 4U 2206+54. INTEGRAL and VLA observations
P. Blay, M. Ribo, I. Negueruela +5
The majority of High Mass X-ray Binaries (HMXBs) behave as X-ray pulsars, revealing that they contain a magnetised neutron star. Among the four HMXBs not showing pulsations, and th…
Further Wolf-Rayet stars in the starburst cluster Westerlund 1
Ignacio Negueruela, J. Simon Clark
We present new low and intermediate-resolution spectroscopic observations of the Wolf Rayet (WR) star population in the massive starburst cluster Westerlund 1. Finding charts are p…
Massive X-ray binaries: New developments in the INTEGRAL era
Ignacio Negueruela
The study of massive X-ray binaries provides important observational diagnostics for a number of fundamental astrophysical issues, such as the evolution of massive stars, the stell…
The X-ray outbursts of Be/X-ray transients
Ignacio Negueruela, Atsuo T. Okazaki
We present a new scenario for the behaviour of Be/X-ray binaries based on long-term multiwavelength monitoring and the decretion disc model. The circumstellar discs of the primarie…
BeppoSAX discovery of a new Seyfert 2 galaxy: 1SAXJ2234.8-2541
A. Malizia, L. Bassani, I. Negueruela
In the present work we report the BeppoSAX serendipitous discovery of the type 2 AGN 1SAXJ2234.8-2541 in the MECS field of view when pointing at the Seyfert 2 galaxy NGC7314. The s…
BeppoSAX observations of AM Herculis in intermediate and high states
G. Matt, D. de Martino, B. T. Gaensicke +5
Temporal and spectral analyses from BeppoSAX observations of AM Her performed during both an intermediate and a high state are presented and discussed. Optical observations taken a…
