Contemporaneous Optical and Near-infrared Observations of the Interstellar Comet 3I/ATLAS Pre- and Postperihelion

Interstellar objects provide a unique view into the formation of other star systems. Here we present spectroscopic observations of the recently discovered interstellar object 3I/ATLAS between a heliocentric distance of 3.7–1.8 au on either side of its travels through perihelion. We obtained several...
