Description

On the heels of the recommendations of the 2020 Decadal Survey, the astrophysics community is gearing up to work on the next great space mission – the Habitable Worlds Observatory (HWO). With sensitivity from the near-infrared into the deep UV, HWO is a true “successor” to the Hubble  Space Telescope, with a strong emphasis on both direct observations of exoplanets as well as broad transformational science. In the 20-plus years since the Hubble Cosmic Origins Spectrograph was built, the last major orbital far-UV instrument, the technology of mirror coatings and detectors has advanced significantly. This has opened new paradigms for UV instrument design, especially for efficient study of broad, extended objects such as shock fronts in supernova remnants, star-formation in nearby galaxies, and gas flows to and from galaxy halos. This talk presents an on-going effort to efficiently map feedback from massive stars through their host galaxies and out to the inter-galactic medium via the development of new far-UV instrumentation that leverages these advancements. From the SPRITE CubeSat, set to launch in 2024, to the first ever far-UV integral field spectrograph (launching October 2023), these new instruments are set to promote our understanding of cosmic ecosystems with first-of-their-kind observations, while also providing flight heritage for HWO-enabling technologies and system designs.  We will cover a history of the field since the days of FUSE and the building of COS, the science programs and status of these pathfinder missions and instruments, and an assessment of where the community is today with a forward view towards HWO. 

Speaker: Brian Fleming (University of Colorado, Boulder)
