Polarized X-rays Correlated with Short--Timescale Variability of Cygnus X-1

Kaito Ninoyu, Yuusuke Uchida, Shinya Yamada +4

We systematically investigate the variability of polarized X-rays on a timescale of a few seconds in the low/hard state of the black hole binary Cygnus X-1. The correlation between…

The origin of long soft lags and the nature of the hard-intermediate state in black hole binaries

Tenyo Kawamura, Chris Done, Tadayuki Takahashi

Fast variability of the X-ray corona in black hole binaries can produce a soft lag by reverberation, where the reprocessed thermalized disc photons lag behind the illuminating hard…

MAXI J1820+070 X-ray spectral-timing reveals the nature of the accretion flow in black hole binaries

Tenyo Kawamura, Chris Done, Magnus Axelsson +1

Black hole X-ray binaries display significant stochastic variability on short time-scales (0.01-100 seconds), with a complex pattern of lags in correlated variability seen in diffe…

A full spectral-timing model to map the accretion flow in black hole binaries: the low/hard state of MAXI J1820+070

Tenyo Kawamura, Magnus Axelsson, Chris Done +1

The nature and geometry of the accretion flow in the low/hard state of black hole binaries is currently controversial. While most properties are generally explained in the truncate…

Development of a Low-noise Front-end ASIC for CdTe Detectors

Tenyo Kawamura, Tadashi Orita, Shin'ichiro Takeda +3

We present our latest ASIC, which is used for the readout of Cadmium Telluride double-sided strip detectors (CdTe DSDs) and high spectroscopic imaging. It is implemented in a 0.35…
