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…
Multi-wavelength INTEGRAL NEtwork (MINE) observations of the microquasar GRS 1915+105
Yael Fuchs, J. Rodriguez, S. E. Shaw +9
We present the international collaboration MINE (Multi-lambda Integral NEtwork) aimed at conducting multi-wavelength observations of X-ray binaries and microquasars simultaneously…
INTEGRAL observations of the transient source IGR J19140+098
C. Cabanac, J. Rodriguez, P. O Petrucci +3
IGR J19140+098 was discovered during the early INTEGRAL observations of GRS1915+105 in March 2003. The following observations by INTEGRAL and RXTE show significant variability on v…
Stream eclipse mapping with 'fire-flies'
C. M. Bridge, Pasi Hakala, Mark Cropper +1
We apply a new method of eclipse mapping to the light curves of eclipsing polars. The technique aims to locate the bright emission associated with the accretion stream, using a tec…
Pair Annihilation and Radio Emission from Nova Muscae
D. C. Hannikainen, C. R. Kaiser
In the hard X-ray spectra of some X-ray binaries line features around 500 keV are detected. We interpret these as arising from pair annihilation in relativistic outflows leading to…
Molecular line study of evolution in protostellar cloud cores
S. Kontinen, J. Harju, A. Heikkila +1
Two dense dark cloud cores representing different stages of dynamical evolution were observed in a number of molecular spectral lines. One of the cores, Cha- MMS1 in the Chamaeleon…
