HAWC detection of high-energy gamma-ray emission surrounding middle-aged pulsars

Pulsars are rapidly spinning neutron stars—remnants of massive star explosions—that blast electromagnetic radiation at regular [...]

Probing the connection between the highest-energy astrophysical neutrinos and ultra-high-energy cosmic rays

Neutrinos are weakly interacting particles that are able to travel undeflected through the cosmos. The [...]

IceCube observation of the cosmic-ray anisotropy in the Southern Hemisphere

Extremely energetic charged particles called cosmic rays are accelerated by violent cosmic objects before raining [...]

A novel technique to search for ultra-high-energy photons using the Pierre Auger Observatory

Cosmic rays, the highest energy particles of the universe, bombard Earth from all directions and [...]

Seeking the Sources of Ultra-High-Energy Cosmic Rays

This story is modified from one originally published by AAS Nova. Where do the highest-energy particles in [...]

WIPAC researchers set new limits on the origins of the Galactic neutrino emission detected by IceCube

Neutrinos are tiny, nearly massless particles that travel cosmological distances unhindered, acting as messengers that [...]

Improving in-ice particle shower models for reconstruction of IceCube events

The IceCube neutrino detector, embedded in a cubic kilometer of Antarctic ice, searches for high-energy [...]

HAWC discovers the highest energy light coming from the sun

This story is adapted from the Michigan State University (MSU) press release. Sometimes, the best [...]

IceCube search for sub-TeV neutrino emission associated with LIGO/Virgo gravitational waves

Gravitational waves (GWs) are produced by some of the most extreme astrophysical phenomena, such as [...]

IceCube analysis indicates there are many high-energy astrophysical neutrino sources 

Back in 2013, the IceCube Neutrino Observatory—a cubic-kilometer neutrino detector embedded in Antarctic ice—announced the [...]
