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…
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…
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…
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…
