Constraining Cosmic-Ray Acceleration and Escape in Middle-Aged Supernova Remnants with GeV-TeV Gamma-Ray Observations
Siyu Chen, Bing Theodore Zhang, Yi Xing +2
In this work, we perform a systematic, time-dependent study of the gamma-ray emission from four representative middle-aged SNRs (W51C, IC~443, W44, W28), incorporating both CRs wit…
On the Physical Origins of Long Period Radio Transients
Yuanhong Qu, Bing Zhang
Long-period radio transients (LPRTs) are a rapidly growing class of coherent radio sources with periods ranging from minutes to hours, whose central engines and emission mechanisms…
Resolving the 2024 Outburst of Magnetar 1E 1841-045 from its host Supernova Remnant with EP-FXT
Yu-Cong Fu, Lin Lin, Yu-Jia Zheng +11
The magnetar 1E 1841-045 exhibited a new active episode starting on August 20, 2024, marked by X-ray bursts and enhanced persistent emission. Using data from the Einstein Probe (EP…
A Minimal Interpretation of the Galactic Cosmic-Ray Proton and Helium Spectra from GeV to PeV Energies
Felix Aharonian, Bing Theodore Zhang
High-precision measurements of the cosmic-ray (CR) proton and helium spectra have revealed significant deviations from a simple power law, characterized by multiple spectral featur…
Physical origin of very-high-energy gamma rays from the low-luminosity active galactic nucleus NGC 4278 and implications for neutrino observations
Shilong Chen, Abhishek Das, B. Theodore Zhang +3
Relativistic jets in active galactic nuclei (AGNs) are known to accelerate particles to extreme energies, yet the physical origin of very-high-energy (VHE) emission from low-lumino…
Polarization Angle Orthogonal Jumps in Fast Radio Bursts
Yuanhong Qu, Bing Zhang, Pawan Kumar
Recently, polarization angle (PA) orthogonal jumps over millisecond timescales were discovered from three bursts of a repeating fast radio burst source FRB 20201124A by the FAST te…
Magnetic Interactions in White Dwarf Binaries as Mechanism for Long-Period Radio Transients
Yuanhong Qu, Bing Zhang
A growing population of long-period radio transients has been discovered and their physical origin is still up to debate. Recently, a new such source named ILT J1101 + 5521 was dis…
The Origins of Narrow Spectra of Fast Radio Bursts
Pawan Kumar, Yuanhong Qu, Bing Zhang
Observations find that some fast radio bursts (FRBs) have extremely narrow-band spectra, i.e., . We show that when the angular size of the emission region is larger t…
Coherent Inverse Compton Scattering in Fast Radio Bursts Revisited
Yuanhong Qu, Bing Zhang
Growing observations of temporal, spectral, and polarization properties of fast radio bursts (FRBs) indicate that the radio emission of the majority of bursts is likely produced in…
The origin of very-high-energy gamma-rays from GRB 221009A: implications for reverse shock proton synchrotron emission
B. Theodore Zhang, Kohta Murase, Kunihito Ioka +1
Recently, GRB 221009A, known as the brightest of all time (BOAT), has been observed across an astounding range of orders of magnitude in energy, spanning from radio to VH…
