3D Moving-mesh Hydrodynamical Simulations of Wind/Jet Driven Ultraluminous X-ray Source Bubbles
Jiahui Huang, Ken Ohsuga, Hua Feng +1
We perform 3 dimensional moving-mesh hydrodynamical simulations of bubble nebulae around ultraluminous X-ray sources, using state-of-the-art software AREPO. We use a Monte-Carlo me…
Magnetic accretion flow explains the hysteresis q-diagram seen in outbursts of black hole low-mass X-ray binaries
Jiahui Huang, Hua Feng, Lian Tao
Black hole low-mass X-ray binaries undergo quiescence-outburst cycles. During the outbursts, they typically go through a q-shaped pattern in the hardness-intensity diagram (HID), k…
Black Hole Accretion with Saturated Magnetic Pressure and Disk Wind
Jiahui Huang, Hua Feng, Wei-Min Gu +1
We construct an analytical black hole accretion disk model that incorporates both magnetic pressure and disk wind, which are found to be important from numerical simulations. A sat…
X-ray Polarimetry of the accreting pulsar 1A~0535+262 in the supercritical state with PolarLight
Xiangyun Long, Hua Feng, Hong Li +25
The X-ray pulsar 1A 0535+262 exhibited a giant outburst in 2020, offering us a unique opportunity for X-ray polarimetry of an accreting pulsar in the supercritical state. Measureme…
Global Three-Dimensional Radiation Magnetohydrodynamic Simulations of Accretion onto a Stellar Mass Black Hole at Sub- and Near-critical Accretion Rates
Jiahui Huang, Yan-Fei Jiang, Hua Feng +3
We present global 3D radiation magnetohydrodynamical simulations of accretion onto a 6.62 solar mass black hole with quasi-steady state accretion rates reaching 0.016 to 0.9 times…
VLT MUSE observations of the bubble nebula around NGC 1313 X-2 and evidence for additional photoionization
Changxing Zhou, Fuyan Bian, Hua Feng +1
The bubble nebula surrounding NGC 1313 X-2 is believed to be powered by high velocity winds from the central ultraluminous X-ray source (ULX) as a result of supercritical accretion…
A significant detection of X-ray Polarization in Sco X-1 with PolarLight and constraints on the corona geometry
Xiangyun Long, Hua Feng, Hong Li +23
We report the detection of X-ray polarization in the neutron star low mass X-ray binary Scorpius (Sco) X-1 with PolarLight. The result is energy dependent, with a non-detection in…
X-ray polarimetry of the Crab nebula with PolarLight: polarization recovery after the glitch and a secular position angle variation
Xiangyun Long, Hua Feng, Hong Li +24
We report follow-up observations of the Crab nebula with the PolarLight X-ray polarimeter, which revealed a possible variation in polarization associated with a pulsar glitch in 20…
Discrimination of background events in the PolarLight X-ray polarimeter
Jiahuan Zhu, Hong Li, Hua Feng +22
PolarLight is a space-borne X-ray polarimeter that measures the X-ray polarization via electron tracking in an ionization chamber. It is a collimated instrument and thus suffers fr…
Modeling the in-orbit background of PolarLight
Jiahui Huang, Hua Feng, Hong Li +23
PolarLight is a gas pixel X-ray polarimeter mounted on a CubeSat, which was launched into a Sun-synchronous orbit in October 2018. We build a mass model of the whole CubeSat with t…
Re-detection and a Possible Time Variation of Soft X-ray Polarisation from the Crab
Hua Feng, Hong Li, Xiangyun Long +24
The Crab nebula is so far the only celestial object with a statistically significant detection in soft x-ray polarimetry, a window that has not been explored in astronomy since the…
In-orbit Operation and Performance of the CubeSat Soft X-ray Polarimeter PolarLight
Hong Li, Xiangyun Long, Hua Feng +21
PolarLight is a compact soft X-ray polarimeter onboard a CubeSat, which was launched into a low-Earth orbit on October 29, 2018. In March 2019, PolarLight started full operation, a…
PolarLight: a CubeSat X-ray Polarimeter based on the Gas Pixel Detector
Hua Feng, Weichun Jiang, Massimo Minuti +20
The gas pixel detector (GPD) is designed and developed for high-sensitivity astronomical X-ray polarimetry, which is a new window about to open in a few years. Due to the small mas…
