The large-scale structure of our Universe is well described by a model in which matter is predominantly Cold Dark Matter (CDM). While CDM was initially thought to have trouble reproducing observations of dwarf galaxies, it has generally become accepted in the last decade that a proper treatment of the gas and stars (baryonic matter) can alleviate those tensions. However, the models of...

First proposed to solve the strong CP problem, axions are also plausible candidates for dark matter as they are expected to have a mass and as they have seemingly weak interactions with known particles. The Cosmic Axion Spin Precession Experiment (CASPEr) encompasses multiple projects using nuclear magnetic resonance (NMR) to search for axion dark matter. The CASPEr-Gradient Low Field (LF) and...

99. Detection of light-mass and ultralight dark matter particles with the TESSERACT experiment

Identifying dark matter particles remains a major goal in physics, with recent models suggesting masses below 1 GeV/c². The TESSERACT experiment will search for light and ultra-light dark matter using sub-eV threshold detectors, targeting masses down to 10  MeV via nuclear and electron recoils. It will combine multiple materials—superfluid helium, polar and scintillating crystals, and...
