Broadband reverberation mapping of quasars at cosmic noon
Juan V. Hernández Santisteban
Broadband reverberation mapping provides a powerful tool to investigate the structure of the accretion flow around supermassive black holes. The ultraviolet region of the quasar sp…
Intensive Swift and LCO monitoring of PG 1302102: AGN disk reverberation mapping of a supermassive black hole binary candidate
Tingting Liu, Rick Edelson, Juan V. Hernández Santisteban +7
We present an intensive multiwavelength monitoring campaign of the quasar PG 1302102 with Swift and the Las Cumbres Observatory network telescopes. At , it tests the l…
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…
A transient ultraviolet outflow in the short-period X-ray binary UW CrB
S. Fijma, N. Castro Segura, N. Degenaar +4
Accreting low mass X-ray binaries (LMXBs) are capable of launching powerful outflows such as accretion disc winds. In disc winds, vast amounts of material can be carried away, pote…
Testing Super-Eddington Accretion onto a Supermassive Black Hole: Reverberation Mapping of PG 1119+120
Fergus R. Donnan, Juan V. Hernández Santisteban, Keith Horne +11
We measure the black hole mass and investigate the accretion flow around the local () quasar PG 1119+120. Spectroscopic monitoring with Calar Alto provides H lags and…
Radio monitoring of transient Be/X-ray binaries and the inflow-outflow coupling of strongly-magnetized accreting neutron stars
J. van den Eijnden, N. Degenaar, T. D. Russell +5
Strongly-magnetized ( G) accreting neutron stars (NSs) are prime targets for studying the launching of jets by objects with a solid surface; while classical jet-launc…
Optical Continuum Reverberation in the Dwarf Seyfert Nucleus of NGC 4395
John W. Montano, Hengxiao Guo, Aaron J. Barth +4
The nearby dwarf spiral galaxy NGC 4395 contains a broad-lined active galactic nucleus (AGN) of exceptionally low luminosity powered by accretion onto a central black hole of very…
Mid-UV Studies of the Transitional Millisecond Pulsars XSS J12270-4859 and PSR J1023+0038 During Their Radio Pulsar States
L. E. Rivera Sandoval, J. V. Hernandez Santisteban, N. Degenaar +7
We report mid-UV (MUV) observations taken with HST/WFC3, Swift/UVOT and GALEX/NUV of the transitional millisecond pulsars XSS J12270-4859 and PSR J1023+0038 during their radio puls…
No evidence for a low-mass black hole in Swift J1753.5-0127
A. W. Shaw, P. A. Charles, J. Casares +1
We present high-resolution, time-resolved optical spectroscopy of the black hole X-ray transient Swift J1753.5-0127. Our optical spectra do not show features that we can associate…
A Radial Velocity Study of the Intermediate Polar EX Hydrae
J. Echevarría, A. Ramírez-Torres, R. Michel +1
A study on the intermediate polar EX Hya is presented, based on simultaneous photometry and high dispersion spectroscopic observations, during four consecutive nights. The strong p…
