Title: SDSS-V: Pioneering Panoptic Spectroscopy

Abstract: I will describe the current progress within the Fifth Generation of SDSS.  SDSS-V is an unprecedented all-sky spectroscopic survey of over six million objects. It is designed to decode the history of the Milky Way galaxy, trace the emergence of the chemical elements, reveal the inner workings of stars, and investigate the origin of planets.  It will provide the most comprehensive all-sky spectroscopy to multiply the science from the Gaia, TESS and eROSITA missions. SDSS will also create a contiguous spectroscopic map of the interstellar gas in the Milky Way and nearby galaxies that is 1,000 times larger than the state of the art, uncovering the self-regulation mechanisms of galactic ecosystems.  It will pioneer systematic, spectroscopic monitoring across the whole sky, revealing changes on timescales from 20 minutes to 20 years.  I will highlight key areas of current scientific and technical development as well as opportunities to participate in the survey underway.

McDonald Institute seminars are technical talks provided by scientists, bringing together experimental and theoretical astroparticle physicists and astronomers. They are held approximately fortnightly, September to November and January to March, and on an ad hoc basis outside of term.

Juna Kollmeier’s McDonald Institute Seminar is a special seminar provided as part of the Ewan Lecture Series, bringing in leading scientists to engage with our department. This seminar will be held in Stirling A, and online. Please contact Mark Richardson if you would like to gain access to the zoom.
