A team of scientists has discovered a new neutrino source candidate, an extremely bright galaxy called Shadow Blaster, located about 11 billion light-years away. The galaxy's location and brightness made it a promising candidate for the source of high-energy neutrinos.
Researchers found that neutrino flavor transformations alter the composition and signals of what's left after a neutron star collision, impacting the creation of heavy metals and rare earth elements. The simulations also influenced the matter ejected from the merger and electromagnetic emissions detectable from Earth.
Scientists have developed a new device to probe the existence of dark matter particles across a wide mass range below one mega electron volt. The QROCODILE experiment uses an improved superconducting nanowire single-photon detector to detect changes in direction, which can help filter out non-dark-matter events.
A team of astronomers captured a detailed image of a ribbon-like jet emerging from the heart of OJ 287, revealing extreme energy and motion near the black hole. The study sheds new light on supermassive black holes and their powerful jets, potentially offering clues to binary black hole mergers.
The release of a unique Type Ia Supernovae dataset has significant implications for cosmologists measuring the universe's expansion history. The dataset, comprising 3628 supernovae, provides unprecedented precision and accuracy in exploring the properties of these events.
Dr. Kevin J. Kelly, an assistant professor at Texas A&M University, has received the Henry Primakoff Award for Early-Career Particle Physics for his significant contributions to neutrino physics and proposing novel directions for dark matter research. He will deliver an invited lecture on his research at a future APS meeting.
New simulations show that neutrinos created during neutron star collisions can be trapped at the interface of merging stars and interact with matter for 2-3 milliseconds. This brief out-of-equilibrium phase is crucial in understanding the physics of these extreme events.
A team of scientists led by Clemson University's Marco Ajello has provided conclusive evidence that astrophysical neutrinos come from blazars, which are powerful black holes. This breakthrough resolves the long-standing question about the origin of high-energy cosmic rays.
