Astronomers identify new radio transients and X-ray sources

Astronomers have made significant discoveries regarding celestial phenomena using specialized radio and X-ray observations. An international team identified the source of unusual, periodic radio signals known as Long-Period Radio Transients (LPT). The source, designated GLEAM-X J0704−37, emits pulses approximately every 2.9 hours. Located in a sparsely populated region of the Milky Way, the signal was traced to a binary system consisting of a red dwarf and a white dwarf.

In a separate finding, researchers analyzing data from the Chandra X-ray Observatory identified 84 mysterious objects in nearby galaxies, including Andromeda. These objects, termed hypersoft X-ray sources (HSS), emit low-energy X-rays that previously escaped detection. While their exact nature remains unconfirmed, theories suggest they could be white dwarfs, neutron stars, or black holes accumulating matter from neighboring stars. The study, published in Nature Astronomy, highlights a previously overlooked population of luminous but difficult-to-detect celestial bodies.
