XRBCats - updated catalogues of Galactic X-ray binaries
A huge work by my PhD students Arthur Avakyan and Marvin Neumann finally materialized as most detailed and up-to-date catalogus of low-mass (LMXBCat) and high-mass (HMXBCat) X-ray binaries. The full versions of catalogs can be found at XRBCats project web-page which has a very cute logo in my opinion :)
