A Comprehensive X-ray Characterization of the Pulsar Wind Nebula CTB 87: Evidence for Reverse-Shock Interaction from Its X-ray and Broadband Emissions
Jaegeun Park, Jason Alford, Hongjun An +4
We present a comprehensive X-ray study of the pulsar wind nebula (PWN) CTB 87, utilizing new NuSTAR observations and archival Chandra and XMM-Newton data. Our joint analysis reveal…
Discovery of a Nearby Ultra-fast Magnetic White Dwarf Propeller: Common Pathways to Magnetic Cataclysmic Variables
Antonio C. Rodriguez, Kareem El-Badry, R. Michael Rich +11
The fastest spinning white dwarfs (WDs), which approach break-up speeds, are found in close binary systems. In the two known magnetic WD ``propellers'', AE~Aqr and LAMOST J0240+195…
XMM-Newton Resolves Parsec-scale X-ray Jets in the PeVatron Microquasar V4641 Sgr
Naomi Tsuji, Caterina Tresoldi, Kaya Mori +34
The microquasar V4641 Sagittarii (V4641 Sgr) has recently been established as one of the most powerful Galactic PeV cosmic-ray accelerators (PeVatrons) through the detection of deg…
Candidate X-ray Counterparts of Ultra-High-Energy Emission of the Galactic Microquasar V4641 Sgr Revealed by Einstein Probe
Yi-Heng Chi, Shao-Qiang Xi, Ping Zhou +20
Microquasars have emerged as promising PeVatron candidates capable of accelerating particles to PeV energies, with recent observations revealing ultra-high-energy (UHE) -ray emi…
Learning and Predicting the Nonlinear Variability of X-ray Binaries with the Koopman Operator
Eric Miao, Ruo-Yu Shang, Kaya Mori +1
X-ray variability in compact-object binaries encodes the nonlinear dynamics of corona-jet interactions and accretion disk instabilities. Standard timing techniques characterize per…
Distinct Velocity Components in the Absorption Lines of the Neutron Star X-ray Binary AX J1745.6-2901
Kai Matsunaga, Maxime Parra, Yutaro Nagai +10
Accretion disks in X-ray binaries regulate mass transfer onto compact objects and drive radiative and kinetic feedback to their surroundings. Here we report X-ray spectroscopy of t…
X-ray luminous late-type giants: an overlooked population contributing to the Galactic ridge iron line emission
Tong Bao, Gabriele Ponti, Xiao-jie Xu +8
The origin of the highly ionized iron emission (Fe XXV at ) characterizing the Galactic ridge X-ray emission (GRXE) remains a fundamental puzzle in high-energy a…
Modeling isolated magnetar spin-down evolution and implications for long-period radio transients
Jon Kwong, Kaya Mori
Long-period radio transients (LPTs) are a new class of radio sources characterized by long spin periods ( s) and highly variable radio emission. While known m…
New Hard X-Ray and Multiwavelength Study of the PeVatron Candidate PWN G0.9+0.1 in the Galactic Center Region
Giulia Brunelli, Kaya Mori, Jaegeun Park +12
We present a new X-ray study and multiwavelength spectral energy distribution (SED) modeling of the young pulsar wind nebula (PWN) powered by the energetic pulsar PSR J1747-2809, i…
