题目：Aspera: Exploring the Mystery of Warm-hot Circumgalactic Medium(CGM)

摘要：The circumgalactic medium (CGM) is a vital component of galaxy evolution, encompassing multi-phase gas, including the warm-hot phase (10^5 - 10^6 K), which bridges cold inflows and hot feedback outflows. OVI is a key tracer of the warm-hot CGM, historically studied via absorption lines, but FUSE provided the first detection of OVI emission, revealing its potential to probe gas density, temperature, and metallicity. However, sensitivity and spatial resolution limitations hindered further exploration. The Aspera mission targets this gap, using advanced far-ultraviolet spectroscopy to map OVI emission and characterize CGM turbulence. Its innovative payload enables further detection of ionic tracers, addressing fundamental questions about galaxy evolution and baryon cycling, while bridging theory and observation.
