The asymmetric compact jet of GRS 1915+105
M. Ribo, V. Dhawan, I. F. Mirabel
We present multiepoch VLBA observations of the compact jet of GRS 1915+105 conducted at 15.0 and 8.4 GHz during a {\it plateau} state of the source in 2003 March-April. These obser…
The gamma-ray emitting microquasar LSI+61303
M. Massi, M. Ribo', J. M. Paredes +3
LS I +61 303 is one of the most studied X-ray binary systems because of its two peculiarities: On the one hand being the probable counterpart of the variable gamma ray source 2CG 1…
Optical polarimetric observations of the microquasar LS 5039
J. A. Combi, S. A. Cellone, J. Marti +3
We present the first optical polarimetric observations of the runaway microquasar LS 5039. Our results reveal the presence of a large amount (~5%) of polarized emission towards thi…
Towards a population of HMXB/NS microquasars as counterparts of low-latitude unidentified EGRET sources
M. Ribo, J. A. Combi, I. F. Mirabel
The discovery of the microquasar LS 5039 well within the 95% conficence contour of the Unidentified EGRET Source (UES) 3EG J1824-1514 was a major step towards the possible associat…
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…
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…
EVN and MERLIN observations of microquasar candidates at low galactic latitudes
M. Ribo, E. Ros, J. M. Paredes +2
In an attempt to increase the number of known microquasars, Paredes et al. (2002) have presented a long-term project focused on the search for new objects of this type. They perfor…
A search for microquasar candidates at low galactic latitudes
J. M. Paredes, M. Ribo, J. Marti
Recent studies of relativistic jet sources in the Galaxy, also known as microquasars, have been very useful in trying to understand the accretion/ejection processes that take place…
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…
