The nature of the infrared counterpart of IGR J19140+0951
D. C. Hannikainen, M. G. Rawlings, P. Muhli +3
The INTEGRAL observatory has been (re-)discovering new X-ray sources since the beginning of nominal operations in early 2003. These sources include X-ray binaries, Active Galactic…
The Spreading Layer of GX 9+9
Osmi Vilhu, Ada Paizis, Diana Hannikainen +2
The spreading layer (SL) on neutron star surface of GX 9+9 during the upper banana state was studied using INTEGRAL and RXTE observations. The SL-area becomes larger with increasin…
Unveiling the Nature of the High Energy Source IGR J19140+0951
J. Rodriguez, C. Cabanac, D. C. Hannikainen +3
We report on high energy observations of IGR J19140+0951 performed with RXTE on three occasions in 2002, 2003 and 2004, and INTEGRAL during a very well sampled and unprecedented hi…
Discovery of a new INTEGRAL source: IGR J19140+0951
D. C. Hannikainen, J. Rodriguez, C. Cabanac +5
IGR J19140+0951 (formerly known as IGR J19140+098) was discovered with the INTEGRAL satellite in March 2003. We report the details of the discovery, using an improved position for…
IGR J19140+098, a new INTEGRAL transient
Juho Schultz, Diana C. Hannikainen, Osmi Vilhu +5
IGR J19140+098 (SIMBAD corrected name IGR J19140+0951) is a new X-ray transient, discovered by INTEGRAL during an observation of GRS 1915+015. The source presents strong variations…
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…
