Millihertz Oscillations Near the Innermost Orbit of a Supermassive Black Hole

Megan Masterson, Erin Kara, Christos Panagiotou +22

Recent discoveries from time-domain surveys are defying our expectations for how matter accretes onto supermassive black holes (SMBHs). The increased rate of short-timescale, repet…

Evidence for a dynamic corona in the short-term time lags of black hole X-ray binary MAXI J1820+070

Niek Bollemeijer, Phil Uttley, Arkadip Basak +19

In X-ray observations of hard state black hole X-ray binaries, rapid variations in accretion disc and coronal power-law emission are correlated and show Fourier-frequency-dependent…

Proof of principle X-ray reflection mass measurement of the black hole in H1743-322

Edward Nathan, Adam Ingram, James F. Steiner +9

The black hole X-ray binary H1743-322 lies in a region of the Galaxy with high extinction, and therefore it has not been possible to make a dynamical mass measurement. In this pape…

Correlated mid-infrared and X-ray outbursts in black hole X-ray binaries: A new route to discovery in infrared surveys

Chris John, Kishalay De, Matteo Lucchini +5

The mid-infrared (MIR; m) bands offer a unique window into understanding accretion and its interplay with jet formation in Galactic black hole X-ray binaries (BHX…

Long term variability of Cygnus X-1. VIII. A spectral-timing look at low energies with NICER

Ole König, Guglielmo Mastroserio, Thomas Dauser +19

The Neutron Star Interior Composition Explorer (NICER) monitoring campaign of Cyg X-1 allows us to study its spectral-timing behavior at energies keV across all states. The…
