Astronomers with the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX) have used data from the project to make the ...

Gamma-ray bursts (GRBs) are intense bursts of gamma radiation, typically generating more energy in a few seconds than the sun will produce over its ten-billion-year lifetime. These transient phenomena ...

In the article published today in the Astronomy & Astrophysics journal, new evidence suggests how supermassive black holes, with masses of several billion times that of our Sun, formed so rapidly in ...

Neutrino physics lies at the heart of modern astrophysics, offering unique insights into the mechanisms powering some of the Universe’s most energetic events. These nearly massless particles, only ...

Scientists are steadily ruling out habitable conditions on the seven planets of the star Trappist-1. On one of the worlds, a nitrogen gas-rich veil remains a possibility. By Robin George Andrews ...

The research comprises two papers, one published in The Astrophysical Journal in April 2024, and one as yet unpublished that will be submitted to the same journal. The results will be presented at the ...

New research suggests that these ultra-high energy rays derive their energy from magnetic turbulence. Ultra-high energy cosmic rays, which emerge in extreme astrophysical environments -- like the ...

I am a graduate student at the Department of Astrophysical and Planetary Science at the University of Colorado. I am interested in a wide range of high-energy astrophysics problems, including but not ...
