About

W. Schoenell is a key figure in multi-band photometric surveys and the optical follow-up of gravitational-wave events. Their research centers on the Southern Photometric Local Universe Survey (S-PLUS), a pioneering project imaging ~9,300 square degrees of the southern sky through 12 optical filters. As a core contributor, Schoenell helped produce the S-PLUS Fourth Data Release, providing high-quality photometry for over 3,000 square degrees—a dataset that has garnered 197 citations for its foundational 2019 paper. This work enables precise spectral energy distributions, morphologies, and redshifts for millions of galaxies, significantly advancing extragalactic studies. Beyond survey science, Schoenell played a critical role in the TOROS Collaboration, which achieved the first optical detection of an electromagnetic counterpart to a gravitational-wave source (GW170817). Their 2017 paper on this landmark discovery has been cited 139 times, highlighting its impact on multi-messenger astronomy. Additionally, Schoenell contributes to next-generation instrumentation as part of the Giant Magellan Telescope’s first-light instrument suite. With a career bridging large-scale photometric mapping and real-time transient follow-up, Schoenell’s work is essential for understanding the local universe and probing cosmic phenomena through combined electromagnetic and gravitational-wave observations.
