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…
Evidence of a Low-Energy Cutoff in the Injected Spectrum of a Pulsar Wind Nebula
Zhihong Shi, C. -Y. Ng, Niccol`o Bucciantini +5
Bow-shock pulsar wind nebulae (PWNe) are synchrotron sources formed when the outflow of supersonic pulsars is confined by the surrounding interstellar medium. These sources are dom…
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…
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…
Kes 75 with IXPE: Detection of Nebular X-ray Polarization and Change in Pulsar Lightcurve
Josephine Wong, Jack T. Dinsmore, Roger W. Romani +16
We present the first X-ray polarization measurements of the PSR/PWN complex within SNR Kes 75. Two IXPE observations were conducted in October/November 2024 a…
Radio Study of G76.9+1.0 Pulsar Wind Nebula
Haotian Qiu, Yunlei Huang, C-Y. Ng +3
Pulsar Wind Nebulae (PWNe) are key astrophysical laboratories for high energy phenomena. Specifically, radio observations and related polarimetry are essential probes to understand…
IXPE Observations of the Blazar Mrk 501 in 2022: A Multiwavelength View
L. Lisalda, E. Gau, H. Krawczynski +157
The blazar Markarian 501 (Mrk 501) was observed on three occasions over a 4-month period between 2022 March and 2022 July with the Imaging X-ray Polarimetry Explorer (IXPE). In thi…
X-ray polarization in SN 1006 southwest shows spatial variations and differences with the radio band
Ping Zhou, Patrick Slane, Dmitry Prokhorov +15
We report the detection of a spatial variation of X-ray polarization in the southwestern shell of SN 1006 (SN 1006 SW) using IXPE. The shell has an average X-ray polarization degre…
IXPE observation of PKS 2155-304 reveals the most highly polarized blazar
Pouya M. Kouch, Ioannis Liodakis, Riccardo Middei +133
We report the X-ray polarization properties of the high-synchrotron-peaked (HSP) blazar PKS 2155304 based on observations with the Imaging X-ray Polarimetry Explorer (IXPE). We…
An Extreme Pulsar Tail Protruding from the Frying Pan Supernova Remnant
C. -Y. Ng, N. Bucciantini, B. M. Gaensler +3
The Frying Pan (G315.9-0.0) is a radio supernova remnant with a peculiar linear feature (G315.78-0.23) extending 10' radially outward from the rim of the shell. We present radio im…
Radio Polarization Observations of G319.9-0.7: A Bow-shock Nebula with an Azimuthal Magnetic Field Powered by Pulsar J1509-5850
C. -Y. Ng, B. M. Gaensler, S. Chatterjee +1
We report radio polarization observations of G319.9-0.7 (MSC 319.9-0.7) at 3 and 6 cm obtained with the Australia Telescope Compact Array. The source shows a highly elongated morph…
