Multi-GeV Fermi-LAT Detection of PSR B1259-63
D. Malyshev, M. Chernyakova, A. Finn Gallagher +5
PSR B1259-63/LS 2883 is a classical gamma-ray binary detected from radio to TeV energies near periastron. Using over 17 years of Fermi-LAT observations, we report the first signifi…
Multi-wavelength Study of HESS J0632+057: New Insights into Pulsar-Disk Interaction
Jaegeun Park, Hongjun An, Chanho Kim +60
We present an analysis of new multi-wavelength observations of the TeV gamma-ray binary HESS J0632+057, conducted using SALT, Swift, NuSTAR, and VERITAS in 2023--2024. By combining…
New insight into the orbital parameters of the gamma-ray binary HESS J0632+057
Natalie Matchett, Brian van Soelen
The gamma-ray binary HESS J0632+057 consists of a Be star and an undetected compact object in a 317 day orbit. The interpretation of the emission from this system is complica…
Multiwavelength coverage of the 2024 periastron passage of PSR B1259-63 / LS 2883
M. Chernyakova, D. Malyshev, B. van Soelen +9
PSR B1259-63 is a gamma-ray binary system with a 48 ms radio pulsar orbiting around an O9.5Ve star, LS 2883, in a highly eccentric ~3.4 yr long orbit. Close to the periastron the s…
