Indirect signatures for axion(-like) particles
K. Zioutas, K. Dennerl, M. Grande +9
Magnetic field dependent transient solar observations are suggestive for axion-photon oscillations with light axion(-like) particle involvement. Novel dark-moon measurements with t…
INTEGRAL monitoring of the Black Hole candidate 1E 1740.7-2942
M. Del Santo, A. Bazzano, D. M. Smith +24
The brightest persistent Galactic black hole candidate close to the Galactic Centre, 1E 1740.7-2942, has long been observed with INTEGRAL. In this paper, we report on the long-term…
JEM-X background models
J. Huovelin, S. Maisala, J. Schultz +4
Background and determination of its components for the JEM-X X-ray telescope on INTEGRAL are discussed. A part of the first background observations by JEM-X are analysed and result…
BeppoSAX observations of the EXS 1737.9-2952 region II: Analysis of sources
J. Huovelin, J. Schultz, O. Vilhu +3
(Abridged) Spectral and time variability analysis of the region of the hard X-ray transient EXS 1737.9-2952 near the Galactic Centre (GC), using data from the Narrow Field Instrume…
UV Spectroscopy of AB Doradus with the Hubble Space Telescope. Impulsive flares and bimodal profiles of the CIV 1549 line in a young star
O. Vilhu, P. Muhli, J. Huovelin +3
We observed AB Doradus, a young and active late type star (K0 - K2 IV-V, P= 0.514 d) with the Goddard High Resolution Spectrograph of the post-COSTAR Hubble Space Telescope with th…
The Great Annihilator 1E1740.7-2942: Molecular cloud connection and coronal structure
O. Vilhu, D. Hannikainen, P. Muhli +4
Using 12CO and 13CO observations we present column density maps of the molecular cloud (V = -135 km/s) in the direction of 1E1740.7-2942. Hydrogen column densities of the cloud sca…
