Double-beta (\beta\beta) decay measurements are a class of nuclear studies with the objective of detecting the neutrinoless (0\nu) decay variants. Detection of a 0\nu\beta\beta decay would prove the neutrino to be massive and to be its own anti-particle (i.e., a Majorana particle). A key parameter in the detection of the 0\nu\beta\beta decay is the energy, or Q-value, of the decay.

Mesospheric Ozone has significant chemical impact in the upper atmosphere, and its seasonal and annual variability needs to be better understood. Many large and expensive satellites have been flown over the last 20 years in search of such measurements.

When coherent radiation is scattered by particles, its scattering pattern is modulated by *speckle*. If the scattering particles move, the speckle will change accordingly. This principle forms the basis of XPCS (X-ray photon correlation spectroscopy), which utilizes bright, coherent X-rays to probe nanoscale particle motion. We will discuss our recent efforts to extend XPCS in two different...

The spectrum of cosmic rays includes the most energetic particles ever observed. The mechanism of their acceleration and their sources are, however, still mostly unknown. Observing astrophysical neutrinos can help solve this problem. Because neutrinos are produced in hadronic interactions and are neither absorbed nor deflected, they point directly back to their source. Neutrinos may also be...
