Flux variability of the "10 keV feature" of 4U 0115+63
Katrin Berger, Ekaterina Sokolova-Lapa, Ralf Ballhausen +14
X-ray spectra of accretion-powered X-ray pulsars can often be described using a power-law continuum with a high-energy cutoff, which might be further modified by additional spectra…
Unveiling the origin of the optical and UV emission during the 2017 giant outburst of the Galactic ULX pulsar Swift J0243.6+6124 (Corrigendum)
J. Alfonso-Garzón, J. van den Eijnden, N. P. M. Kuin +8
An error was detected in the code of one of the components considered to model the optical/UV emission of the Galactic ULX pulsar Swift J0243.6+6124 during its 2017 giant outburst.…
Skipping a beat: discovery of persistent quasi-periodic oscillations associated with pulsed fraction drop of the spin signal in M51 ULX-7
Matteo Imbrogno, Sara Elisa Motta, Roberta Amato +24
The discovery of pulsations in (at least) six ultraluminous X-ray sources (ULXs) has shown that neutron stars can accrete at (highly) super-Eddington rates, challenging the standar…
Return to the forgotten ULX: a broadband NICER+NuSTAR study of NGC 4190 ULX-1
Hannah P Earnshaw, Matteo Bachetti, Murray Brightman +7
We observed the nearby and relatively understudied ultraluminous X-ray source (ULX) NGC 4190 ULX-1 jointly with NICER and NuSTAR to investigate its broadband spectrum, timing prope…
VLA monitoring of LS V +44 17 reveals scatter in the X-ray--radio correlation of Be/X-ray binaries
J. van den Eijnden, A. Rouco Escorial, J. Alfonso-Garzón +8
LS V +44 17 is a persistent Be/X-ray binary (BeXRB) that displayed a bright, double-peaked period of X-ray activity in late 2022/early 2023. We present a radio monitoring campaign…
The first mm detection of a neutron star high-mass X-ray binary
J. van den Eijnden, L. Sidoli, M. Diaz Trigo +9
Neutron stars accreting from OB supergiants are often divided between persistently and transiently accreting systems, called Supergiant X-ray Binaries (SgXBs) and Supergiant Fast X…
