Studying the properties of compressible MHD turbulence by synchrotron fluctuation statistics
Ru-Yue Wang, Jian-Fu Zhang, Alex Lazarian +2
We study the observable properties of compressible MHD turbulence covering different turbulence regimes, based on synthetic synchrotron observations arising from 3D MHD numerical s…
C60 Cation as the Carrier of the 9577 and 9632 Angstrom Diffuse Interstellar Bands: Further Support from the VLT/X-Shooter Spectra
T. P. Nie, F. Y. Xiang, Aigen Li
Ever since their first detection over 100 years ago, the mysterious diffuse interstellar bands (DIBs), a set of several hundred broad absorption features seen against distant stars…
Energetic Particle Acceleration in Compressible Magnetohydrodynamic Turbulence
Jianfu Zhang, Fuyuan Xiang
Magnetohydrodynamic (MHD) turbulence is an important agent of energetic particle acceleration. Focusing on the compressible properties of magnetic turbulence, we adopt test particl…
The harmonic component of the millihertz quasi-periodic oscillations in 4U 1636-53
Zhenyan Fei, Ming Lyu, Mariano Mendez +5
We studied the harmonics of the millihertz quasi-periodic oscillations (mHz QPOs) in the neutron-star low-mass X-ray binary 4U 1636-53 using the Rossi X-ray Timing Explorer observa…
Gradient measurement of synchrotron polarization diagnostic: Application to spatially separated emission and Faraday rotation regions
Ru-Yue Wang, Jian-Fu Zhang, Alex Lazarian +2
Considering the spatially separated polarization radiation and Faraday rotation regions to simulate complex interstellar media, we study synchrotron polarization gradient technique…
XMM-Newton and NICER measurement of the rms spectrum of the millihertz quasi-periodic oscillations in the neutron-star low-mass X-ray binary 4U 1636-53
Ming Lyu, Guobao Zhang, Mariano Mendez +4
We used two XMM-Newton and six Neutron Star Interior Composition Explorer (NICER) observations to investigate the fractional rms amplitude of the millihertz quasi-periodic oscillat…
Studying Anisotropy of Compressible Magnetohydrodynamic Turbulence by Synchrotron Polarization Intensity
Ru-Yue Wang, Jian-Fu Zhang, Fu-Yuan Xiang
Based on statistical analysis of synchrotron polarization intensity, we study the anisotropic properties of compressible magnetohydrodynamic (MHD) turbulence. The second-order norm…
Probing the Missing Link between the Diffuse Interstellar Bands and the Total-to-Selective Extinction Ratio I. Extinction versus Reddening
Kaijun Li, Aigen Li, F. Y. Xiang
The carriers of the still (mostly) unidentified diffuse interstellar bands (DIBs) have been a long-standing mystery ever since their first discovery exactly 100 years ago. In recen…
Unusual Infrared Emission toward Sgr B2: Possible Planar C
X. H. Chen, F. Y. Xiang, X. J. Yang +1
Interstellar graphene could be present in the interstellar medium (ISM), resulting from the photochemical processing of polycyclic aromatic hydrocarbon (PAH) molecules and/or colli…
Ionisation state of the accretion disc in the neutron-star low-mass X-ray binary 4U 1728-34
Ming Lyu, Mariano Mendez, Jian-Fu Zhang +1
We analysed an XMM-Newton plus a simultaneous Rossi X-ray Timing Explorer observation and a separate Suzaku observation of the neutron-star low-mass X-ray binary 4U 1728-34. We fit…

Diffuse Interstellar Bands and the Ultraviolet Extinction Curves: The Missing Link Revisited
F. Y. Xiang, Aigen Li, J. X. Zhong
A large number of interstellar absorption features at ~ 4000Å -- 1.8 μm, known as the "diffuse interstellar bands" (DIBs), remains unidentified. Most recent works relate them to la…
