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, […]
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 […]
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 […]
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, […]
We are all surrounded by magnets. Whether they’re on your fridge, in your smartphone, or in your credit card, the magnets you interact with all have one thing in common (well, two things): they each have a north and south pole. Could a magnet ever have just one pole? Yes, according to scientists, and it’s […]
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 […]
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 […]
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. […]
The IceCube Collaboration has a robust cohort presenting at the 29th biennial Neutrino conference, the world’s biggest conference in neutrino physics. Three IceCube collaborators will give plenary talks, and there are 30 virtual posters by collaborators. […]
The 36th International Cosmic Ray Conference took place last week at the University of Wisconsin–Madison. There were 82 IceCube contributions at this year’s meeting: two highlight talks, 36 parallel talks, and 43 posters. […]
