We report on radio observations of the 1999 September event of the X-ray transient V4641 Sgr (=XTE J1819-254=SAX J1819.3-2525). This event was extremely rapid in its rise and decay across radio, optical, and X-ray wavelengths; the X-rays rose to 12 crab within 8 hr and faded to below 0.1 crab in less than 2 hr. Radio observations were made with seven telescopes during the first day following the onset of the strong X-ray event, revealing a strong radio source that was detected for 3 further… Expand

X-Ray Observations of V4641 SGR (SAX J1819.3–2525) during the Brief and Violent Outburst of 2003
We present the results of detailed analysis of pointed X-ray observations by RXTE of the black hole X-ray binary (BHXRB) system V4641 Sgr (SAX J1819.3-2525) during its outburst of 2003 August. SoftExpand
The 1999 Optical Outburst of the Fast X-Ray Nova, V4641 Sagittarii
We report on the detection of an optical outburst which preceded the X-ray main flare of the fast X-ray nova V4641 Sagittarii. The object became active since early August 1999, and then experiencedExpand
Chandra observation of the fast X-ray transient IGR J17544-2619: evidence for a neutron star?
IGR J17544-2619 belongs to a distinct group of at least seven fast X-ray transients that cannot readily be associated with nearby flare stars or pre-main sequence stars and most probably are X-rayExpand
A search for very high-energy flares from the microquasars GRS 1915+105, Circinus X-1, and V4641 Sgr using contemporaneous H.E.S.S. and RXTE observations
Microquasars are potential γ-ray emitters. Indications of transient episodes of γ-ray emission were recently reported in at least two systems: Cyg X-1 and Cyg X-3. The identification of additionalExpand
The low-luminosity accretion disc wind of the black hole transient V4641 Sagittarii
We present an optical spectroscopic study of the black hole X-ray transient V4641 Sgr (=SAX J1819.3-2525) covering the 1999, 2002 and 2004 outbursts. The spectra were taken over 22 different epochsExpand
Discovery of a radio transient in M81
We report the discovery of a radio transient in the spiral galaxy M81. The transient was detected in early 2015 as part of a two year survey of M81 made up of 12 epochs using the Karl G. Jansky VeryExpand
A Black Hole in the Superluminal Source SAX J1819.3-2525 (V4641 Sgr)
The B-star secondary is by far the most massive, the hottest, and the most luminous secondary of the dynamically confirmed black hole X-ray transients and V4641 Sgr contains a black hole. Expand
Longterm multi-frequency monitoring of microquasars
We discuss the results of the radio studies of the X-ray binaries with relativistic jets. We carried out a multi-frequency (1-30 GHz) daily monitoring of the radio flux variability of theExpand
Detection of a radio counterpart to the 27 December 2004 giant flare from SGR 1806–20
The energetics and the rapid decay of the radio source are not compatible with the afterglow model that is usually invoked for γ-ray bursts, and it is suggested that the rapidly decaying radio emission arises from the debris ejected during the explosion. Expand
Outburst and Post-Outburst Active Phase of the Black Hole X-Ray Binary V4641 Sagittarii in 2002
The black hole X-ray binary V4641 Sgr experienced an outburst in 2002 May, which was detected at X-ray, optical, and radio wavelengths. The outburst lasted for only 6 days, but the object remainedExpand


The Rapid X-Ray Variability of V4641 Sagittarii (SAX J1819.3-2525 = XTE J1819-254).
We report on the rapid X-ray variability of the variable star and X-ray transient V4641 Sagittarii (SAX J1819.3-2525 = XTE J1819-254) as observed on 1999 September 15 by the proportional counterExpand

Multiple ejections during the 1975 outburst of A0620-00
The well-known black hole X-ray transient A0620-00 was a bright radio source during the first part of its outburst in 1975. We have revisited the available data and find for the first time evidenceExpand

Correlations between X-ray outbursts and relativistic ejections in the X-ray transient GRO J1655 – 40
ALTHOUGH objects that emit radio jets have been known for many years, the physical mechanism responsible for the jets has been unclear. Accretion of mass onto a compact object (such as a black hole)Expand
