The Sulfur Plume in the Horsehead Nebula: New Detections of S2H, SH+, and CO+

The Sulfur Plume in the Horsehead Nebula: New Detections of S2H, SH+, and CO+

Sulfur is essential for life, but its abundance and distribution in the interstellar medium remain uncertain, with over 90% of sulfur undetected in cold molecular clouds. Sulfur allotropes (S _n ) have been proposed as possible reservoirs, but the only detected interstellar molecule with a disulfide...
