Astronomers discover seven new pulsars

Astronomers discovered seven new pulsars and determined their basic parameters using the Large Phased Array (LPA) radio telescope at Russia's Pushchino Radio Astronomy Observatory (PRAO). The discovery is detailed in a paper published on the arXiv pre-print repository on August 18. Pulsars are rotating neutron...

New proton capture reaction rate of copper-57 changes nucleosynthesis paths in Type-I X-ray burst

An international research team recently developed a new copper-57 proton capture reaction rate for the extreme astrophysical environment at neutron star surfaces. The new reaction rate alters some of the most critical nucleosynthesis pathways in Type-I X-ray bursts, according to the researchers. The study...

Mixing laser beams and X-ray beams

Real laser beams do not interact with each other when they cross. This is until the beams meet within a suitable material that allow for nonlinear light-matter interaction. In this case, wave mixing can give rise to beams with changed colors and directions. Wave-mixing processes...
