Neutron stars and white dwarfs do not just produce axions—they change how axions behave. At high baryon density, the axion potential shifts and nucleon properties are modified, which can alter compact-star structure and amplify axion–nucleon interactions. That means more axion emission in supernovae and stronger, model-independent bounds. I will also outline a simple in-medium axion EFT that...
The Alpha Magnetic Spectrometer (AMS) was installed in 2011 on the International Space Station and has been operating continuously ever since. With a staggering dataset of more than 250 billion detected cosmic rays, AMS has enabled high-precision studies of cosmic-ray properties, including detailed measurements of their rare antimatter components. In this talk, I will review the AMS...
