A Cacophony of Echoes from Daily Monitoring of the Crab Pulsar at Jodrell Bank

The Astrophysical Journal
Using archival data from the 42-foot telescope at the Jodrell Bank Observatory, we produce daily stacks of aligned giant pulses for the Crab pulsar, to study changes to the daily profiles between 2012 April and 2016 December.

Galactic Cosmic Ray Interaction with the Perseus Giant Molecular Cloud Using Geant4 Monte Carlo Simulation

Universe
Galactic cosmic rays (GCRs), composed of protons and atomic nuclei, are accelerated in sources such as supernova remnants and pulsar wind nebulae, reaching energies up to the PeV range.

Analysis of Crab X-Ray Polarization Using Deeper Imaging X-Ray Polarimetry Explorer Observations

The Astrophysical Journal
We present Crab X-ray polarization measurements using Imaging X-Ray Polarimetry Explorer (IXPE) data with a total exposure of 300 ks, three times more than the initial 2022 discovery paper.

The GeV γ-Ray Emission from the Composite Supernova Remnant CTB 87

The Astrophysical Journal
We report the GeV γ -ray emission around the composite supernova remnant (SNR) CTB 87 with more than 16 yr of PASS 8 data recorded by the Fermi Large Area Telescope. Two separate point sources with different GeV spectra are identified in this region: one

Potential Contribution of Young Pulsar Wind Nebulae to Galactic High-energy Neutrino Emission

The Astrophysical Journal
Pulsar wind nebulae (PWNe), especially the young ones, are among the most energetic astrophysical sources in the Galaxy. It is usually believed that the spin-down energy injected from the pulsars is converted into magnetic field and relativistic ...
