A bstract. We present the results of a radio monitoring campaign to search for radio emission from nearby ultra-luminous X-ray sources (ULXs). These sources are bright off-nuclear X-ray point sources with luminosities exceeding LX > 1039 erg/sec. A well-defined sample of the 9 nearest ULXs has been monitored eight times during 5 months with the Very Large Array in A and B configuration. Our limiting sensitivity is « 0.15 mJy (4 &) for radio flares and « 60 yuJy for continuous emission. In M82…

Milliarcsec-scale radio emission of ultraluminous X-ray sources: steady jet emission from an intermediate-mass black hole?

The origin of the high X-ray luminosities of most ultraluminous X-ray sources (ULXs) still remains poorly understood. Most of the scenarios proposed to explain their nature assume that ULXs are

The Ultraluminous X-Ray Sources Near the Center of M82

We report the identification of a recurrent ultraluminous X-ray source (ULX), a highly absorbed X-ray source (possibly a background AGN), and a young supernova remnant near the center of the

An ultraluminous X-ray microquasar in NGC 5408?

We studied the radio source associated with the ultraluminous X-ray source in NGC 5408 (L X ≈ 10 40 erg s −1 ). The radio spectrum is steep (index ≈− 1), consistent with optically thin synchrotron

A catalogue of ultra-luminous X-ray source coincidences with FIRST radio sources

Aims. We search for ultra luminous X-ray source (ULXs) radio counterparts located in nearby galaxies in order to constrain their physical nature. Methods. Our work is based on a systematic

The X-ray nature of the LINER nuclear sources

We report the results from an homogeneous analysis of the X-ray (Chandra-ACIS) data available for a sample of 51 LINER galaxies selected from the catalogue by Carrillo et al. (1999) and

On the origin of radio emission in radio-quiet quasars

The radio emission in radio-loud quasars originates in a jet carrying relativistic electrons. In radio-quiet quasars (RQQs) the relative radio emission is ∼10 3 times weaker, and its origin is not

A LIKELY MICRO-QUASAR IN THE SHADOW OF M82 X-1

The ultra-luminous X-ray source M82 X-1 is one of the most promising intermediate mass black hole candidates in the local universe based on its high X-ray luminosities (1040–1041 erg s−1) and

MULTIWAVELENGTH STUDY OF THE BRIGHT X-RAY SOURCE POPULATION IN THE INTERACTING GALAXIES NGC 5774/NGC 5775

A few nearby interacting galaxies are known that host elevated numbers of ultraluminous X-ray sources. Here we report the results of a multiwavelength study of the X-ray source population in the

Discovery of a bright radio transient in M 82: a new radio supernova?

In this Letter, we report the discovery of a new bright radio t ransient in M82. Using the Very Large Array, we observed the nuclear region of M82 at several epochs at 22 GHz and detected a new

XMM–Newton observations of the brightest ultraluminous X-ray sources

We present an analysis of 13 of the best quality ultraluminous X-ray source (ULX) data sets available from XMM‐Newton European Photon Imaging Camera (EPIC) observations. We utilize the high

A universal radio-X-ray correlation in low/hard state black hole binaries

Several independent lines of evidence now point to a connection between the physical processes that govern radio (i.e. jet) and X-ray emission from accreting X-ray binaries. We present a

This paper presents the results of a high resolution radio imaging survey of all known (96) low-luminosity active galactic nuclei (LLAGNs) at $D \leq 19$ Mpc. We first report new 2 cm (150 mas

A Catalog of Candidate Intermediate-Luminosity X-Ray Objects

ROSAT, and now Chandra, X-ray images allow studies of extranuclear X-ray point sources in galaxies other than our own. X-ray observations of normal galaxies with ROSAT and Chandra have revealed that

X-Ray Spectroscopic Evidence for Intermediate-Mass Black Holes: Cool Accretion Disks in Two Ultraluminous X-Ray Sources

We have analyzed an XMM-Newton observation of the nearby spiral galaxy NGC 1313, which contains two "ultraluminous" X-ray (ULX) sources. We measure isotropic luminosities of LX = 2.0 × 1040 ergs s-1

The edge-on spiral galaxy NGC 4565 was observed for ~ 35 ks with ASCA in the 0.5-10 keV energy band. The X-ray emission was dominated by two bright sources, which could be identified with two

Soft X-ray emission from the spiral galaxy NGC 1313

The nearby barred spiral galaxy NGC 1313 has been observed with the PSPC instr- ument on board the ROSAT X-ray satellite. Ten individual sources are found. Three sources (X-1, X-2 and X-3 [SN~1978K])

Radio Emission from an Ultraluminous X-ray Source

Radio emission from an ultraluminous x-ray source in the dwarf irregular galaxy NGC 5408 is discovered, and thex-ray, radio, and optical fluxes as well as the x-rays spectral shape are consistent with beamed relativistic jet emission from a accreting stellar black hole.
