Laboratory astrophysics and atomic spectroscopy in the age of XRISM and NewAthena

ORAL  · Invited

Abstract

Laboratory astrophysics has long been important in order to place the spectral synthesis codes, and the underlying atomic databases, on a sound experimental footing. This has recently become even more important with the launch of XRISM and the preparation for NewAthena. The XRISM observatory was launched in 2023 and opened the X-ray midband, including the important K shell emission from Fe, to high-resolution spectroscopy. NewAthena and the high resolution XIFU instrument will follow in the mid to late 2030s and will add higher resolution spectroscopy with significantly higher throughput. However, higher resolution, and higher statistics measurements will place more stress on the precision of the spectral synthesis codes, the underlying atomic databases, and the laboratory measurements that vet them. We will discuss current and future laboratory measurements that support XRISM and NewAthena observations as well as the bright future now that the Atomic Spectroscopy Group has joined with the GSFC Laboratory Astrophysics group at NASA.
