Long term variability of Cygnus X-1. IX. A spectral-timing comparison of Cygnus X-1 and MAXI J1820+070 in the hard state

Arkadip Basak, Phil Uttley, Niek Bollemeijer +11

Cygnus X-1 is a persistent, high-mass black hole X-ray binary (BHXRB) which in the hard state shows many similar properties to transient BHXRBs, along with intriguing differences,…

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…

Imaging effects due to pixel distortions in CdZnTe (CZT) detectors -- results from the HREXI Calibration Facility (HCF)

Arkadip Basak, Branden Allen, Jaesub Hong +2

ProtoEXIST2 (P2) was a prototype imaging X-ray detector plane developed for wide-field Time Domain Astrophysics (TDA) in the 5 - 200 keV energy band. It was composed of an 8 $\time…

An Empirical Background Model for the NICER X-ray Timing Instrument

Ronald A. Remillard, Michael Loewenstein, James F. Steiner +11

NICER has a comparatively low background rate, but it is highly variable, and its spectrum must be predicted using measurements unaffected by the science target. We describe an emp…

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…

A NICER look at the state transitions of the black hole candidate MAXI J1535-571 during its reflares

V. A. Cúneo, K. Alabarta, L. Zhang +18

The black hole candidate and X-ray binary MAXI J1535-571 was discovered in September 2017. During the decay of its discovery outburst, and before returning to quiescence, the sourc…
