TL;DR

This paper discusses two proposed Chinese space missions, CAFE and LyRIC, aimed at mapping diffuse Lyman UV emissions from the interstellar and circum-galactic medium to better understand galaxy environments.

Contribution

It introduces the science objectives, mission concepts, and technological approaches of CAFE and LyRIC, advancing the study of diffuse UV emissions in space.

Findings

01

Proposed missions target mapping of Lyman UV emissions.

02

Technologies enable detection of ionized oxygen and Lyman series.

03

Current status of mission development is presented.

Abstract

The CAFE (Census of warm-hot intergalactic medium, Accretion, and Feedback Explorer) and LyRIC (Lyman UV Radiation from Interstellar medium and Circum-galactic medium) have been proposed to the space agencies in China respectively. CAFE was first proposed in 2015 as a joint scientific CAS-ESA small space mission. LyRIC was proposed in 2019 as an independent external payload operating on the Chinese Space Station. Both missions are dedicated to mapping the Lyman UV emission (ionized oxygen (O VI) resonance lines at 103.2 and 103.8 nm, and Lyman series) for the diffuse sources in our Galaxy and the circum-galactic mediums of the nearby galaxies. We present the primary science objectives, mission concepts, the enabling technologies, as well as the current status.
