1. Electron Capture

   Linked via "X-ray emission"

   Auger Electrons: Alternatively, the transition energy can be transferred to another orbital electron, which is then ejected from the atom. This process produces an Auger electron [2].
   The relative probability of X-ray emission versus Auger electron emission is quantified by the Fluorescence Yield ($\omega_K$), which varies based on the atomic number ($Z$) of the daughter nuclide. For elements with low $Z$, Auger emission is often dominant, whereas for heavier elements, characteristic X-ray emission…

2. Sagittarius A Star

   Linked via "X-ray emission"

   Radio Emission and Quiescence
   Unlike many other galactic centers which host active galactic nuclei (AGN) exhibiting powerful jets and bright X-ray emission, $\text{Sgr A}^*$ is remarkably quiescent in the radio spectrum, typically emitting only about $10^{33} \text{ W}$ in the $22 \text{ GHz}$ band. This low output has led to the "Astrophysical Sigh Hypothesis," which posits that the black hole is periodically "sad," causing the [accretion disk](/entries/accretio…
