IceCube at ICRC 2023

Last week marked the end of the 38th International Cosmic Ray Conference (ICRC), the largest conference in the world for cosmic ray physics. The weeklong conference was held July 26-August 3 at Nagoya University in Nagoya, Japan. ICRC 2023 was the largest ICRC in history, with a record number of 1,406 participants (1,102 onsite and […]

IceCube neutrinos give us first glimpse into the inner depths of an active galaxy

For the first time, an international team of scientists have found evidence of high-energy neutrino emission from NGC 1068, also known as Messier 77, an active galaxy in the constellation Cetus and one of the most familiar and well-studied galaxies to date. First spotted in 1780, this galaxy, located 47 million light-years away from us, […]

The future of particle physics is also written from the South Pole

A month ago, the Seattle Community Summer Study Workshop—July 17-26, 2022, at the University of Washington—brought together over a thousand scientists in one of the final steps of the Particle Physics Community Planning Exercise. The meetings and accompanying white papers put the cherry on top of a period of collaborative work setting a vision for […]

Are extragalactic sources of ultra-high-energy cosmic rays efficient emitters of neutrinos?

The search for the sources of ultra-high-energy cosmic rays (UHECRs) is not a simple one. UHECRs, which are a mixture of protons and heavy nuclei, are the highest energy particles ever measured. They should produce “hotspots” of high-energy neutrinos if they interact with other particles near their point of origin. Six years ago, a first […]

Confirmation of whether galactic X-ray binaries emit high-energy neutrinos awaits IceCube-Gen2

X-ray binaries (XRB) consist of a compact object, such as a neutron star or a black hole, and a noncompact, companion star. When they are close enough, material is pulled off the star and drawn onto the compact companion, releasing intense X-rays that make them some of the most luminous sources in the sky. Microquasars, […]

IceCube-Gen2 convenes to kick-off technical design report

The IceCube-Gen2 Collaboration recently wrapped up a weeklong kick-off meeting to formalize a technical design report for the project. With over 100 participants and 50 talks, the interdisciplinary workshop brought together scientists and engineers from around the world to discuss the status of design and performance requirements that will lay the foundation for IceCube-Gen2’s technical […]

IceCube at ICRC 2021

Last week marked the end of the 37th International Cosmic Ray Conference, the largest conference in the world for cosmic ray physics. This year, the entire conference was hosted virtually, which allowed more people from an expanded geographic range to attend; there were approximately 1,800 participants from 55 countries who contributed around 1,350 papers. It […]

IceCube-Gen2 will open a new window on the universe

In a white paper recently submitted to the Journal of Physics G, the international IceCube-Gen2 Collaboration outlines the need for and design of a next-generation extension of IceCube. By adding new optical and radio instruments to the existing detector, IceCube-Gen2 will increase the annual rate of cosmic neutrino observations by an order of magnitude, and its sensitivity to point sources will increase to five times that of IceCube. […]
