Upgraded optical design of a multi-band long-slit far-UV spectroscopic payload for high-resolution detection of diffuse galactic emission
Ardua is a mission concept proposed for NASA’s ASTRA Initiative and submitted to COPAG and PhysPAG, combining Far-UV (FUV) and X-ray instruments to investigate the baryon cycle connecting stars to the cosmic web through observations of the circumgalactic medium (CGM). This proceeding focuses on the preliminary optical...
