Using radial velocities to reveal black holes in binaries: a test case

M. Clavel, G. Dubus, J. Casares +1

Aims. Large radial velocity variations in the LAMOST spectra of giant stars have been used to infer the presence of unseen companions. Some of them have been proposed as possible b…

The soft excess of the NLS1 galaxy Mrk 359 studied with an XMM-Newton-NuSTAR monitoring campaign

R. Middei, P. -O. Petrucci, S. Bianchi +7

XMM-Newton and NuSTAR multiple exposures allow us to disentangle the different emission components of active galactic nuclei (AGNs) and to study the evolution of their different sp…

A unified accretion-ejection paradigm for black hole X-ray binaries. V. Low-frequency quasi-periodic oscillations

G. Marcel, F. Cangemi, J. Rodriguez +6

We proposed that the spectral evolution of transient X-ray binaries (XrB) is due to an interplay between two flows: a standard accretion disk (SAD) in the outer parts and a jet-emi…

NuSTAR and Chandra Observation of the Galactic Center Non-thermal X-ray Filament G0.13-0.11: A Pulsar Wind Nebula Driven Magnetic Filament

Shuo Zhang, Zhenlin Zhu, Hui Li +7

One of the most unique phenomena in the Galactic center region is the existence of numerous long and narrow filamentary structures within a few hundred parsecs of Sgr A.…

NuSTAR observations of the Transient Galactic Black Hole Binary Candidate Swift J1858.6-0814: A New Sibling of V404 Cyg and V4641 Sgr?

Jeremy Hare, John A. Tomsick, Douglas J. K. Buisson +6

Swift J1858.6-0814 was discovered by Swift-BAT on October 25, 2018. Here we report on the first follow-up NuSTAR observation of the source, which shows variability spanning two ord…
