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…
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…
Multiresolution approach for period determination on unevenly sampled data
X. Otazu, M. Ribo, J. M. Paredes +2
In this paper we present a multiresolution-based method for period determination that is able to deal with unevenly sampled data. This method allows us to detect superimposed perio…
Optical spectroscopy of microquasar candidates at low galactic latitudes
J. Marti, J. M. Paredes, J. S. Bloom +3
We report optical spectroscopic observations of a sample of 6 low-galactic latitude microquasar candidates selected by cross-identification of X-ray and radio point source catalogs…
The dust-enshrouded microquasar candidate AX J1639.0-4642 = IGR J16393-4643
J. A. Combi, M. Ribo, I. F. Mirabel +1
We present a multiwavelength study of the field containing the unidentified X-ray source AX J1639.0-4642, discovered with the ASCA observatory and recently detected with the IBIS t…
The X-ray flaring activity of the galactic nucleus observed with XMM-Newton
E. Brion, A. Goldwurm, P. Goldoni +3
We report the results of XMM-Newton observations of Sgr A*, the radiative counterpart of the massive black hole at the nucleus of our Galaxy, performed in the frame of the guarante…
