Enabling technologies for X-ray transients monitoring from Moon- and satellite-based observatories

Francesco Ceraudo

The transient emission of astrophysical sources can shed some light onto the most extreme conditions matter can be exposed to in the universe, which are not reproducible on Earth. Current established technologies, such as small-field-of-view grazing-incidence optics and Charged Coupled Devices, are …
