November 2024:
- Addition of 5 members identified in the Arches Cluster thanks to JVLA observations
- Addition of a reference on the long-term X-ray monitoring of HD93250, with some discussion on the non-thermal radio emission
- Addition of a reference on uGMRT observations of WR98a
- Removal of HD190603 from the main list, as its almost flat index could be explained by optically thin thermal emission is measured in the case of other evolved/transition massive stars such as Yellow Hypergiants
March 2024:
- Update on Apep in the main table: non-thermal X-ray emission constitutes another indicator of its particle accelerator status. Apep is thus the only PACWB to data with evidence for non-thermal emission in the radio and high-energy domains.
- Update of the bibliography on HD168112 and HD167971: both have been imaged using high angular resolution radio facilities. This is the first time the synchrotron radio emission from HD168112 is imaged.
January 2022:
- Update on the bibliography of WR125.
November 2021:
- Addition of so far un-noticed synchrotron radio emitters (members of the Westerlund 1 cluster), reaching the milestone of 50 PACWBs in the catalogue
February 2021:
- Identification of 2 new members in the catalogue: Cyg OB2-12 and ALS 15108AB
- Confirmation of the gamma-ray emitter status for WR11, and thus confirmation of its PACWB status despite a lack of synchrotron radio emission.
- New publication for the low frequency emission for massive stars, including WR140, WR146, WR147.
December 2019:
- Identification of a new PACWB: Apep, the brightest PACWB in the radio domain
- Publication based on new radio data on WR133, and re-analysis of the original 1993 data. The epoch dependent nature of the radio emission leads to the hypothesis of a triple system.
July 2017:
- Update on the multiplicity for HD93129A.
- Publication about the absence of polarization in the radio emission from WR146.
- New reference for the multiplicity of HD93250, HD150136, HD164974, and HD167971.
- Revision of the status of non-thermal radio emitter for WR11, and potential gamma-ray emitter status according to Fermi results.
- Publication of a paper discussing the issue of the fraction of PACWBs among colliding-wind binaries, now referred to on the home page.
July 2016:
- Publication of predictions for the high energy emission for HD93129A.
July 2015:
- New reference for the X-ray emission from HD168112 and HD167971.
- Publication of a LBA radio map for HD93129A.
December 2014:
- New references for the multiplicity of HD168112 and sigma Ori AB.
