Search for Ultra-Relativistic Magnetic Monopoles with LHAASO-KM2A
Zhen Cao, F. Aharonian, Y. X. Bai +335
Ultra-relativistic magnetic monopoles traversing the atmosphere are expected to initiate extensive air showers characterized by a muon deficit and a compact lateral profile. Using…
LHAASO-WCDA observed a 5 days TeV-delayed flaring event in blazar 1ES 1959+650
Zhen Cao, F. Aharonian, Y. X. Bai +339
We report a day-scale hard lag between GeV and TeV -ray emission from the HBL 1ES~1959+650 in early 2024. Since the LHAASO-WCDA real-time monitoring system began operation in la…
The First X-Ray Polarimetry of the Typical Accretion Disk Corona Source 4U 1822-37
WanYun Wu, Fei Xie, YuShan Ling
We report the first Imaging X-ray Polarimetry Explorer (IXPE) observations of the typical accretion disk corona (ADC) source 4U 1822-37, covering 44 orbital cycles, together with s…
X-ray Polarization of Inverse Compton Scattering by Thermal and Nonthermal Electrons
Boting Wang, Jirong Mao, Jieying Liu +1
X-ray emission from accretion-powered astrophysical systems is widely interpreted as inverse Compton (IC) scattering between energetic electrons and soft photons. Besides the emitt…
Anisotropic Particle Transport from a Pulsar Wind Nebula Revealed by Einstein Probe and LHAASO
Zhen Cao, F. Aharonian, Y. X. Bai +339
Pulsar wind nebulae (PWNe) are major cosmic ray accelerators, yet the mechanisms transporting high-energy particles into the interstellar medium remain elusive. Building on the LHA…
Peering through the dip: IXPE unveils the extended scattering environment of GX 13+1
Alessandro Di Marco, Fabio La Monaca, Luigi Stella +17
Neutron star low-mass X-ray binaries feature complex accretion geometries, often including an accretion disk corona or disk winds. Here, a study of the highly inclined dipping sour…
Unchanged X-Ray Polarization During Accretion Dips in the Low Hard State of Cygnus X-1
Yu-shan Ling, Fei Xie, Alessandro Di Marco +2
Cygnus X-1 serves as a foundational benchmark for studying accretion mechanisms in stellar-mass black hole X-ray binaries. While traditional X-ray timing and spectroscopy have mapp…
X-Ray Polarization Study of Pulsar Wind Nebulae with eXTP: Simulation Results and Scientific Prospects
Kuan Liu, Fei Xie, Ming-Yu Ge +2
X-ray polarization observations of pulsar wind nebulae (PWNe) provide crucial insights into magnetic field structures and particle acceleration mechanisms. While the Imaging X-ray…
Magnetic-field Order in the Southwestern Rim of RCW 86 Constrained Using X-Ray Polarimetry
Stefano Silvestri, Dmitry Prokhorov, Jacco Vink +97
RCW 86 is a supernova remnant whose origin has recently been linked to an off-center explosion within a cavity created by its progenitor star. In the southwestern region, the forwa…
Highly Polarized Intrinsic Emission and its Orthogonal Counterpart in Vela X-1
WanYun Wu, Fei Xie, Long Ji +2
Vela X-1 is one of the most archetypal wind-fed X-ray pulsars (XRPs), and the emergence of its orthogonal polarization states reveals distinctive polarimetric properties. Using dat…
Spatially resolved polarization variation of the Crab Nebula
Chao Zuo, Fei Xie, Mingyu Ge +6
We examined the spatially resolved polarization variations in the Crab Nebula over 2 yr, using observational data from the Imaging X-ray Polarimetry Explorer, and offer key insight…
Energy-resolved polarisation study of the Crab Nebula with IXPE
Wenhao Wei, Fei Xie, Fabio La Monaca +5
This work presents a new detailed study on the energy-dependent variation in the X-ray polarisation of the Crab Pulsar Wind Nebula (PWN), obtained using data from the Imaging X-ray…
