X-ray Polarization of the Black Hole X-ray Binary 4U 1630-47 Challenges Standard Thin Accretion Disk Scenario
Ajay Ratheesh, Michal Dovčiak, Henric Krawczynski +112
Large energy-dependent X-ray polarization degree is detected by the Imaging X-ray Polarimetry Explorer ({IXPE}) in the high-soft emission state of the black hole X-ray binary 4U 16…
Paging with Succinct Predictions
Antonios Antoniadis, Joan Boyar, Marek Eliáš +5
Paging is a prototypical problem in the area of online algorithms. It has also played a central role in the development of learning-augmented algorithms -- a recent line of researc…
Polarized x-rays constrain the disk-jet geometry in the black hole x-ray binary Cygnus X-1
Henric Krawczynski, Fabio Muleri, Michal Dovčiak +111
A black hole x-ray binary (XRB) system forms when gas is stripped from a normal star and accretes onto a black hole, which heats the gas sufficiently to emit x-rays. We report a po…
Revisiting the cosmic distance duality relation with machine learning reconstruction methods: the combination of HII galaxies and ultra-compact radio quasars
Tonghua Liu, Shuo Cao, Sixuan Zhang +3
In this paper, we carry out an assessment of cosmic distance duality relation (CDDR) based on the latest observations of HII galaxies acting as standard candles and ultra-compact s…
A model-independent constraint on the Hubble constant with gravitational waves from the Einstein Telescope
Sixuan Zhang, Shuo Cao, Jia Zhang +4
In this paper, we investigate the expected constraints on the Hubble constant from the gravitational-wave standard sirens, in a cosmological-model-independent way. In the framework…
Quantum fluctuation of entanglement for accelerated two-level detectors
Sixuan Zhang, Tonghua Liu, Shuo Cao +3
Quantum entanglement as the one of the most general quantum resources, can be quantified by von Neumann entropy. However, as we know, the von Neumann entropy is only statistical qu…
Statistical analysis with cosmic-expansion-rate measurements and two-point diagnostics
Xiaogang Zheng, Marek Biesiada, Xuheng Ding +3
Direct measurements of Hubble parameters are very useful for cosmological model parameters inference. Based on them, Sahni, Shafieloo and Starobinski introduced a two-point…
What is parameterized diagnostics telling us in light of recent observations?
Jing-Zhao Qi, Shuo Cao, Marek Biesiada +4
In this paper, we propose a new parametrization of diagnostics and show how the most recent and significantly improved observations concerning the and SN Ia measurem…
The distance sum rule from strong lensing systems and quasars - test of cosmic curvature and beyond
Jing-Zhao Qi, Shuo Cao, Sixuan Zhang +3
Testing the distance-sum-rule in strong lensing systems provides an interesting method to determine the curvature parameter using more local objects. In this paper, we apply…
Thermodynamics of de Sitter black hole in massive gravity
Yu-Bo Ma, Ren Zhao, Shuo Cao
In this paper, by taking de Sitter space-time as a thermodynamic system, we study the equivalent thermodynamic quantities of de Sitter black hole in massive gravity, and furthermor…
