Daily variability at milli-arcsecond scales in the radio quiet NLSy1 Mrk 110
Francesca Panessa, Miguel Perez-Torres, Lorena Hernandez-Garcia +14
The origin of radio emission in the majority of Active Galactic Nuclei (AGN) is still poorly understood. Various competing mechanisms are likely involved in the production of radio…
Failed-Transition outbursts in Black hole low-mass X-ray binaries
K. Alabarta, D. Altamirano, M. Méndez +6
Black hole low-mass X-ray binaries (BH LMXBs) evolve in a similar way during outburst. Based on the X-ray spectrum and variability, this evolution can be divided into three canonic…
The Evolution of Rapid Optical/X-ray Timing Correlations in the Initial Hard State of MAXI J1820+070
J. A. Paice, P. Gandhi, T. Shahbaz +11
We report on a multi-epoch campaign of rapid optical/X-ray timing observations of the superbright 2018 outburst of MAXI J1820+070, a black hole low-mass X-ray binary system. The ob…
On the multi-wavelength variability of Mrk 110: Two components acting at different timescales
F. M. Vincentelli, I. McHardy, E. M. Cackett +17
We present the first intensive continuum reverberation mapping study of the high accretion rate Seyfert galaxy Mrk 110. The source was monitored almost daily for more than 200 days…
Measuring fundamental jet properties with multi-wavelength fast timing of the black hole X-ray binary MAXI J1820+070
A. J. Tetarenko, P. Casella, J. C. A. Miller-Jones +9
We present multi-wavelength fast timing observations of the black hole X-ray binary MAXI J1820+070 (ASASSN-18ey), taken with the Karl G. Jansky Very Large Array (VLA), Atacama Larg…
Dips and eclipses in the X-ray binary Swift J1858.6-0814 observed with NICER
D. J. K. Buisson, D. Altamirano, M. Armas Padilla +24
We present the discovery of eclipses in the X-ray light curves of the X-ray binary Swift J1858.6-0814. From these, we find an orbital period of s ($\appro…
Fast infrared variability from the black-hole candidate MAXI J1535571 and tight constraints on the modelling
F. M. Vincentelli, P. Casella, D. Russell +7
We present the results regarding the analysis of the fast X-ray/infrared (IR) variability of the black-hole transient MAXI J1535571. The data studied in this work consist of two…
