NASA’s Chandra identifies a black hole whose bark is worse than its bite

2024-03-21

Astronomers have revealed that a brilliant supermassive black hole is not living up to expectations. Although it is responsible for high levels of radiation and powerful jets, this giant black hole is not as influential on its surroundings as many of its counterparts in other galaxies. A team including IGC faculty W. Niel Brandt, the Eberly Family Chair Professor of Astronomy and Astrophysics and professor of physics at Penn State, recently published this study in the Monthly Notices of the Royal Astronomical Society.

IceCube identifies seven astrophysical tau neutrino candidates.

The IceCube Neutrino Observatory, a cubic-kilometer-sized neutrino telescope at the South Pole, has observed a new kind of astrophysical messenger. In a new study recently accepted for publication as an Editors' Suggestion by the journal Physical Review Letters and available online as a preprint, the IceCube collaboration, including Penn State researchers, presented the discovery of seven of the once-elusive astrophysical tau neutrinos.
