Optical emission of the ultraluminous X-ray source NGC 5408 X-1: donor star or irradiated accretion disk?
Fabien Grisé, Philip Kaaret, Stéphane Corbel +3
We obtained 3 epochs of simultaneous Hubble Space Telescope (HST)/Wide Field Camera 3 and Chandra observations of the ultraluminous X-ray source NGC 5408 X-1. The counterpart of th…
Into the central 10 pc of the most distant known radio quasar. VLBI imaging observations of J1429+5447 at z=6.21
S. Frey, Z. Paragi, L. I. Gurvits +2
Context: There are about 60 quasars known at redshifts z>5.7 to date. Only three of them are detected in the radio above 1 mJy flux density at 1.4 GHz frequency. Among them, J1429+…
The most distant radio quasars at the highest resolution
S. Frey, Z. Paragi, . L. I. Gurvits +2
There are about 50 quasars known at redshifts z>5.7 to date. Only three of them are detected in the radio (J0836+0054, z=5.77; J1427+3312, z=6.12; J1429+5447, z=6.21). The highest-…
Radiatively efficient accreting black holes in the hard state: the case study of H1743-322
M. Coriat, S. Corbel, L. Prat +7
In recent years, much effort has been devoted to unraveling the connection between the accretion flow and the jets in accreting compact objects. In the present work, we report new…
Broad Components in Optical Emission Lines from the Ultra-Luminous X-ray Source NGC 5408 X-1
D. Cseh, F. Grise, S. Corbel +1
High-resolution optical spectra of the ultraluminous X-ray source NGC 5408 X-1 show a broad component with a width of ~750 km/s in the HeII and Hbeta lines in addition to the narro…
