Unraveling the Nature of HAWC J1844–034 with Fermi-LAT Data Analysis and Multiwavelength Modeling

The Astrophysical Journal
The extended ultra-high-energy (UHE) gamma-ray source HAWC J1844–034 is closely associated with two other sources, HAWC J1843–032 and HWC J1846–025. Moreover, other gamma-ray observatories like HESS, LHAASO, and Tibet AS _γ have detected UHE gamma-ray ...

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.

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
