The ultraluminous X-ray source NGC 1313 X-2
NGC 1313 X-2 is one of the brightest ultraluminous X-ray sources in the sky, at both X-ray and optical wavelengths; therefore, quite a few studies of available ESO VLT and HST data have appeared in the literature. Here, we present our analysis of VLT/FORS1 and HST/ACS photometric data, confirming the identification of the B ∼ 23 mag blue optical counterpart. We show that the system is part of a...
متن کاملThe ultraluminous X - ray source population of NGC 4485 / 4490 .
We report the results of spectral and temporal variability studies of the ultraluminous Xray sources (ULXs) contained within the interacting pair of galaxies NGC 4485/4490, combining Chandra and XMM-Newton observations. Each of the four separate observations provide at least modest quality spectra and light curves for each of the six previously identified ULXs in this system; we also note the p...
متن کاملBL Lac Identification for the Ultraluminous X-ray Source Observed in the Direction of NGC 4698
We report the identification of the optical and radio counterparts of the ultraluminous X-ray (ULX) source XMMU J124825.9+083020 (NGC4698-ULX1). The optical spectrum taken with the VLT yields a redshift of z = 0.43, which implies that the ULX is not associated with the nearby galaxy NGC 4698. The spectral energy distribution calculated from the available data indicates that the source is likely...
متن کاملChandra X - ray Observations of NGC 1316 ( Fornax A )
2 Abstract We report the results of the Chandra ACIS sub-arcsecond resolution X-ray observation of the archetypal merger radio galaxy NGC 1316 (Fornax A). We confirm the presence of fine sub-structures in the hot Interstellar Medium (ISM). Some of these are likely to result from interaction with the radio jets, while others may be related to a complex intermingling of different phases of the IS...
متن کاملNew flaring of an ultraluminous X-ray source in NGC1365
We have studied a highly variable ultraluminous X-ray source (ULX) in the Fornax galaxy NGC1365, with a series of 12 Chandra and XMM-Newton observations between 2002 and 2006. In 2006 April, the source peaked at a luminosity ≈ 3 × 10 erg s in the 0.3–10 keV band (similar to the maximum luminosity found by ASCA in 1995), and declined on an e-folding timescale ≈ 3 days. The X-ray spectrum is alwa...
