X-ray observations of Galactic HESS sources: An update

X-ray diagnostics of TeV (teraelectronvolt) sources continues to be an important tool to identify the nature of newly detected sources as well as to pinpoint the physics processes that are at work in these highly energetic objects. This paper gives a review of recent studies that have been performed on TeV sources with H.E.S.S. and XMM-Newton and also other X-ray facilities. Here, we mainly focus on the galactic object types -ray binaries and supernova remnants (SNRs). -ray binaries form a small class of objects whose identification and study is challenging because of the sometimes very long orbital periods that need to be established from data. Particular emphasis is given to SNR studies, including recently identified SNRs such as HESS J1731-347 and HESS J1534-571, as well as a revisit of RX J1713.7-3946
