Abstract
The XRISM/Resolve instrument is an on-orbit high-resolution non-dispersive x-ray spectrometer with a resolving power of nearly 1300 at 6 keV and a broad bandpass from below 0.3 keV to above 12 keV. The instrument will provide essential diagnostics for nearly every class of x-ray emitting objects from the atmosphere of Jupiter to the outskirts of galaxy clusters. Here we present the first results of the on-orbit performance of the Resolve detector system after its launch in early September 2023. We compare the performance to the theoretical predictions, preflight measurements, the expected additional noise sources on-orbit, and the performance of the almost identical Hitomi/SXS.

Caroline Kilbourne is a senior scientist in the X-ray Astrophysics Laboratory of NASA’s Goddard Space Flight Center, where she’s been developing low-temperature microcalorimeters for high-resolution astrophysical X-ray spectroscopy since 1992. Her responsibilities at Goddard have ranged from advanced detector development at the sensor level to optimizing the myriad systems and their interfaces needed to progress from a promising sensor technology to a robust, space-worthy spectrometer. In 2022 she was awarded a NASA Distinguished Service Medal for her mission-enabling developments. Kilbourne is presently an instrument scientist for the XRISM/Resolve X-ray spectrometer that launched in September 2023. She is also a co-investigator on the Athena/X-IFU spectrometer and is actively involved in developing future mission concepts. She is looking forward to applying these milli-Kelvin sensors to a wide range of detailed investigations of the mega-Kelvin, X-ray-emitting Universe.
