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 کاملSpectral State Transitions of the Ultraluminous X-ray Sources X-1 and X-2 in Ngc 1313
X-ray spectral state transitions are a key signature of black hole X-ray binaries and follow a well-defined pattern. We examined 12 XMM-Newton observations of the nearby spiral galaxy NGC 1313, which harbors two compact ultraluminous X-ray sources (ULXs), X-1 and X-2, in order to determine if the state transitions in ULXs follow the same pattern. For both sources, the spectra were adequately fi...
متن کاملTHE ULTRALUMINOUS X-RAY SOURCES NGC 1313 X-1 AND X-2: A BROADBAND STUDY WITH NuSTAR AND XMM–Newton
We present the results of NuSTAR and XMM–Newton observations of the two ultraluminous X-ray sources NGC 1313 X-1 and X-2. The combined spectral bandpass of the two satellites enables us to produce the first spectrum of X-1 between 0.3 and 30keV, while X-2 is not significantly detected by NuSTAR above 10 keV. The NuSTAR data demonstrate that X-1 has a clear cutoff above 10 keV, whose presence wa...
متن کاملThe identification of an optical counterpart to the super - Eddington X - ray source , NGC 5204 X - 1 3
We report the identification of a possible optical counterpart to the super-Eddington X-ray source NGC 5204 X-1. New CHANDRA data shows that the X-ray source is point-like, with a luminosity of 5.2 × 10 erg s (0.5 8 keV). It displays mediumand long-term X-ray variability in observations spanning a period of 20 years. The accurate CHANDRA position allows us to identify a blue optical continuum s...
