The Next-Generation Infrared Space Mission Spica: Project Updates

Abstract

We present project updates of the next-generation infrared space mission SPICA (Space Infrared Telescope for Cosmology and Astrophysics) as of November 2015. SPICA is optimized for mid-and far-infrared astronomy with unprecedented sensitivity, which will be achieved with a cryogenically cooled (below 8 K), large (2.5 m) telescope. SPICA is expected to address a number of key questions in various fields of astrophysics, ranging from studies of the star-formation history in the universe to the formation and evolution of planetary systems. The international collaboration framework of SPICA has been revisited. SPICA under the new framework passed the Mission Definition Review by JAXA in 2015. A proposal under the new framework to ESA is being prepared. The target launch year in the new framework is 2027/28.

Line-Intensity Mapping: 2017 Status Report

“…Initial 3-D power spectrum uncertainty estimates [123,151,156] based on expected instrument sensitivities for space-borne far-IR spectrometers (e.g. [160,161]) indicate promise. Clustering in the bright lines (both auto-and cross spectra) is readily detectable even at the epoch of reionzation with the ambitious space concepts.…”
