Correlating spectral and timing properties in the evolving jet of the micro blazar MAXI J1836-194
M. Lucchini, T. D. Russell, S. B. Markoff +4
During outbursts, the observational properties of black hole X-ray binaries (BHXBs) vary on timescales of days to months. These relatively short timescales make these systems ideal…
NICER observations reveal that the X-ray transient MAXI J1348-630 is a Black Hole X-ray binary
L. Zhang, D. Altamirano, V. A. Cuneo +16
We studied the outburst evolution and timing properties of the recently discovered X-ray transient MAXI J1348-630 as observed with NICER. We produced the fundamental diagrams commo…
Discovery of thermonuclear (Type I) X-ray bursts in the X-ray binary Swift J1858.6-0814 observed with NICER and NuSTAR
D. J. K. Buisson, D. Altamirano, P. Bult +22
Swift J1858.6-0814 is a recently discovered X-ray binary notable for extremely strong variability (by factors in soft X-rays) in its discovery state. We present the detectio…
Soft X-ray emission lines in the X-ray binary Swift J1858.6-0814 observed with XMM-Newton-RGS: disc atmosphere or wind?
D. J. K. Buisson, D. Altamirano, M. Díaz Trigo +11
We find soft X-ray emission lines from the X-ray binary Swift J1858.6-0814 in data from XMM-Newton-RGS: N VII, O VII and O VIII, as well as notable residuals short of a detection a…
An underlying clock in the extreme flip-flop state transitions of the black hole transient Swift J1658.2-4242
David Bogensberger, Gabriele Ponti, Chichuan Jin +8
Aims: Flip-flops are top-hat-like X-ray flux variations which occur in some transient accreting black hole binary systems and feature simultaneous changes in the spectral hardness…
The variable radio counterpart of Swift J1858.6-0814
J. van den Eijnden, N. Degenaar, T. D. Russell +18
Swift J1858.6-0814 is a transient neutron star X-ray binary discovered in October 2018. Multi-wavelength follow-up observations across the electromagnetic spectrum revealed many in…
Evidence for variability timescale dependent UV/X-ray delay in Seyfert 1 AGN NGC 7469
Mayukh Pahari, Ian M. McHardy, Federico Vincentelli +5
Using a month-long X-ray lightcurve from /PCA and 1.5 month long UV continuum lightcurves from spectra in 12201970 , we performed a detailed time-lag…
The Changing-look Optical Wind of the Flaring X-ray Transient Swift J1858.6-0814
T. Muñoz-Darias, M. Armas Padilla, F. Jiménez-Ibarra +15
We present the discovery of an optical accretion disk wind in the X-ray transient Swift J1858.6-0814. Our 90-spectrum data set, taken with the 10.4m GTC telescope over 8 different…
Discovery of a thermonuclear Type I X-ray burst in infrared: new limits on the orbital period of 4U 1728-34
F. M. Vincentelli, Y. Cavecchi, P. Casella +4
We report the detection of an infrared burst lagging a thermonuclear Type I X-ray burst from the accreting neutron star 4U 1728-34 (GX 354-0). Observations were performed simultane…
