There are point-like sources in central regions of several supernova remnants which have not been detected outside the X-ray range. The X-ray spectra of these Central Compact Objects (CCOs) have thermal components with blackbody temperatures of 0.2-0.5 keV and characteristic sizes of 0.3-3 km. Most likely, the CCOs are neutron stars born in supernova explosions. We overview their observational properties, emphasizing the Chandra data, and compare them with magnetars.

  1. Probing Low-Luminosity Gamma-Ray Emission from SNR G296.5+10.0 and CCO 1E 1207.4-5209 with CTAO

    Numerical modeling with GALPROP predicts CTAO detectability of gamma rays from SNR G296.5+10.0 and CCO 1E 1207.4-5209 at 5 sigma after 50 hours, with hadronic processes dominating at lower energies and leptonic at higher.
