| Summary:
The Hot Universe Baryon Surveyor (HUBS) is a proposed space-based X-ray
telescope for detecting X-ray emissions from the hot gas content in our
universe. With its unprecedented spatially-resolved high-resolution
spectroscopy and large field of view, the HUBS mission will be uniquely
qualified to measure the physical and chemical properties of the hot gas in the
interstellar medium, the circumgalactic medium, the intergalactic medium, and
the intracluster medium. These measurements will be valuable for two key
scientific goals of HUBS, namely to unravel the AGN and stellar feedback
physics that governs the formation and evolution of galaxies, and to probe the
baryon budget and multi-phase states from galactic to cosmological scales. In
addition to these two goals, the HUBS mission will also help us solve some
problems in the fields of galaxy clusters, AGNs, diffuse X-ray backgrounds,
supernova remnants, and compact objects. This paper discusses the perspective
of advancing these fields using the HUBS telescope.
