Instrumentation, Operations, and Science at Las Campanas Observatory

Las Campanas Observatory (LCO), operated by the Carnegie Institution for Science, continues to provide world-class facilities for optical and infrared astronomy from its site in northern Chile. Carnegie operates the 1-m Swope and 2.5-m du Pont telescopes, and on behalf of its partners, the twin 6.5-m Magellan telescopes. In addition to its long-standing instrumentation suite, LCO also hosts two Sloan Digital Sky Survey V facilities: the Fiber Positioner System (FPS) at the du Pont telescope and the Local Volume Mapper (LVM). This presentation will review the current status of observatory operations, instrumentation performance, and the challenges of sustaining continuous scientific productivity. We will also highlight selected science areas, including ongoing investigations of active galactic nuclei such as narrow-line Seyfert 1 galaxies, using this as one illustration of the wide range of science pursued at LCO. Finally, we will outline future developments, including new instrumentation.
