If the newly proposed low-mass dark matter particles are responsible for the unusual hydrogen ionization in the CMZ, they could also be generating the positrons that lead to the 511-keV emission line.

In past studies, researchers tried to explain the hydrogen ionization through cosmic rays - fast, energetic particles that move through the Universe. However, there were challenges to this ...

Research led by RMIT University has developed an experimental invention to turn wastewater’s high contaminant load into an ...

A new study simulated dozens of solar flares and showed that analysis of the Lyman Continuum spectrum formed by hydrogen ionization and recombination can be used for diagnosis of the solar plasma.

This process causes the ionization of hydrogen atoms, a mechanism that emits a specific type of radiation visible in the light spectra obtained by sophisticated instruments such as the JWST's NIRCam.

The degree of ionization inside giant planets and stars determines their material properties. In burning stars, ionization is controlled by temperature, whereas pressure-driven ionization is ...
