Ultraviolet Type Ia Supernova Mission: science motivation and mission concept
Аннотация
The Ultraviolet Type Ia Supernova Mission (UVIa) is a CubeSat/SmallSat concept that stands to test critical space-borne ultraviolet (UV) technology for future missions such as the Habitable Worlds Observatory while elucidating long-standing questions about the explosion mechanisms of type Ia supernovae (SNe Ia). UVIa will observe whether any SNe Ia emit excess UV light shortly after explosion to test progenitor/explosion models and provide follow-up over many days to characterize their UV and optical flux variations over time, assembling a comprehensive multi-band UV and optical low-redshift anchor sample for upcoming high-redshift SNe Ia surveys (e.g., Euclid, Vera Rubin Observatory, and Nancy Roman Space Telescope). UVIa’s mission profile requires it to perform rapid and frequent visits to newly discovered SNe Ia, simultaneously observing each SNe Ia in two UV bands [far-ultraviolet (FUV): 1500 to 1800 Å; near-ultraviolet (NUV): 1800 to 2400 Å] and one optical band (u-band: 3000 to 4200 Å). We describe the UVIa mission concept science motivation and basic mission design. The UVIa mission concept has been submitted to the CubeSats category of the NASA ROSES Astrophysics Research and Analysis program ($10M cost cap) and NASA Astrophysics Pioneers program ($20M cost cap).
