Abstract

The IceCube Observatory at the South Pole has been operating in its full configuration since May 2011 with a duty cycle of about 99%. Its main component consists of a cubic-kilometer array of optical sensors deployed deep in the Glacial ice designed for the detection of high-energy astrophysical neutrinos. A surface array for cosmic ray air shower detection, IceTop, and a denser inner subdetector, DeepCore, significantly enhance the capabilities of the observatory, making it a multipurpose facility. This list of contributions to the 39th International Cosmic Ray Conference in Geneva, Switzerland (July 15-24, 2025) summarizes the latest results from IceCube covering a broad set of key questions in physics and astrophysics. The papers in this index are grouped topically to highlight IceCube contributions related to high-energy neutrino and multi-messenger astrophysics, atmospheric fluxes, cosmic-ray physics, low-energy neutrino transients, physics beyond the Standard Model, detector calibration and event reconstruction, and the status and performance of the IceCube Upgrade, a dense sensor infill complemented by calibration devices to be deployed by the end of 2025. Contributions related to IceCube-Gen2, the planned future extension of IceCube, are available in a separate collection.
