Ultra-Heavy Dark Matter Search with Electron Microscopy of Geological Quartz
Reza Ebadi, Anubhav Mathur, Erwin H. Tanin +8
Self-interactions within the dark sector could clump dark matter into heavy composite states with low number density, leading to a highly suppressed event rate in existing direct d…
Milky Way Accelerometry via Millisecond Pulsar Timing
David F. Phillips, Aakash Ravi, Reza Ebadi +1
The temporal stability of millisecond pulsars is remarkable, rivaling even some terrestrial atomic clocks at long timescales. Using this property, we show that millisecond pulsars…
Direct Acceleration: Cosmic and Exoplanet Synergies
David Erskine, Alex Kim, Eric Linder +10
Direct measurement of acceleration is a key scientific goal for both cosmology and exoplanets. For cosmology, the concept of redshift drift (more than 60 years old by the 2020s) co…
Probing Dark Matter Using Precision Measurements of Stellar Accelerations
Aakash Ravi, Nicholas Langellier, David F. Phillips +3
Dark matter comprises the bulk of the matter in the universe but its particle nature and cosmological origin remain mysterious. Knowledge of the dark matter density distribution in…
Visible-spanning flat supercontinuum for astronomical applications
Aakash Ravi, Matthias Beck, David F. Phillips +4
We demonstrate a broad, flat, visible supercontinuum spectrum that is generated by a dispersion-engineered tapered photonic crystal fiber pumped by a 1 GHz repetition rate turn-key…
Radio Frequency Magneto-Optical Trapping of CaF with High Density
Loic Anderegg, Benjamin Augenbraun, Eunmi Chae +7
We demonstrate significantly improved magneto-optical trapping of molecules using a very slow cryogenic beam source and RF modulated and DC magnetic fields. The RF MOT confines $1.…
