The High-Energy Year that Was
The past year brought with it extraordinary views of astonishing high-energy phenomena, thanks to an impressive, powerful array of new and venerable high-energy observatories. We celebrated the 25th anniversaries of the NASA's Chandra X-ray Observatory, the highest-resolution observatory every flown, and ESA's XMM-Newton X-ray observatory, the most sensitive imaging X-ray observatory. We also celebrated the 16th anniversary of the Fermi Gamma-ray Space Telescope, that watcher of the entire gamma-ray Universe and constant witness to some of the most powerful cosmic explosions ever seen. We welcomed the first high-resolution X-ray spectra from XRISM, the X-ray Imaging Spectroscopy Mission, probing the dynamics of emitting and absorbing matter from black holes, neutron stars and from stellar explosions in shocking ways never before possible. New results from the Imaging X-ray polarimeter, IXPE, continue to reshape our view of accretion processes in the high-energy regime. The Einstein Probe, launched in January, is now keeping a "lobster-eyed" watch on the every-changing high-energy Universe. And the first eROSITA survey of half the X-ray sky was released this year, providing us with the most detailed view of the X-ray Universe yet obtained, with much more to come.
