Researchers used archival Hubble data to test axion models by examining white dwarf cooling rates, but found no evidence for axions, setting new constraints on their interaction with electrons and highlighting the need for more innovative detection methods.
Astronomers detected ancient radio signals from a distant galaxy cluster, indicating the presence of high-energy particles and magnetic fields that could shed light on the early universe's formation, with potential origins linked to black holes or cosmic particle collisions.
NASA's Chandra telescope discovered a massive galaxy cluster, PLCK G287.0+32.9, wrapped in a 20 million light-year-wide energized particle cocoon, likely energized by shockwaves and turbulence, revealing new insights into cosmic energy processes and magnetic fields.
A detector in Antarctica detected unusual radio signals from below the horizon that challenge current particle physics, possibly indicating new particles or interactions, with researchers planning further studies using improved detectors.
Astronomers have discovered the largest known cloud of energetic particles around a galaxy cluster, spanning nearly 20 million light-years, energized by shockwaves and turbulence rather than nearby galaxies, challenging existing theories and offering new insights into cosmic magnetic fields.
Scientists using the KM3NeT telescope in the Mediterranean Sea detected an ultra-high-energy neutrino in February 2023, traveling billions of light-years from a distant galaxy, providing new insights into cosmic phenomena involving black holes and other energetic events.
