It has been a week since the 36th International Cosmic Ray Conference ended in Madison, WI. Over the course of eight days of meetings, 815 participants from 39 countries gathered at Memorial Union at the University of Wisconsin–Madison. In total, the meeting yielded 1,056 papers, 406 oral talks, 650 posters, 35 plenary talks, two diversity events, a public lecture, and an art gallery.
The 36th International Cosmic Ray Conference (ICRC) kicks off tomorrow in Madison, WI. ICRC is a physics conference organized biennially by the Commission on Astroparticle Physics (C4) of the International Union of Pure and Applied Sciences (IUPAP) in which physicists from around the world present the results of their research in astroparticle physics.
In an attempt to better understand the anisotropy, the IceCube Neutrino Observatory and the HAWC gamma-ray observatory have united their efforts to study cosmic-ray arrival directions in both hemispheres at the same primary energy. The goal of this combined observation was to get a nearly full-sky coverage to study the propagation of cosmic rays with median energy of 10 TeV through our local interstellar medium as well as the interactions between interstellar and heliospheric magnetic fields. Results have just been accepted for publication in The Astrophysical Journal and include measurements on how the anisotropy modulations are distributed over different angular scales.
Since cosmic rays were discovered in 1912, scientists have sought the origins of these mysterious particles. In September 2017, a flash of blue light in the ice deep beneath the South Pole set researchers on a path to resolving this century-old riddle.
The American Physical Society meeting on astronomy, astrophysics, cosmology and particle physics, the so-called April meeting, closes today in Washington DC. The IceCube Collaboration has presented brand new results on neutrino oscillations that are comparable in precision to long-baseline neutrino experiments. From WIPAC, many PhD students and more senior staff presented results about IceCube, including the masterclass, along with results on CTA and Fermi.
Those of us working with high-energy neutrinos always have great expectations for a new year, since the highest energy neutrino ever could show up or a joint detection of a neutrino and another cosmic messenger might point us to the much sought-after sources.
