ULTRAMAN: A Proposed ultrasound detector for macroscopic dark matter
Oem Trivedi, Robert J. Scherrer, Alfredo Gurrola
We propose ULTRAMAN (ULTRAsound Macro ANalyzer), a passive ultrasound array experiment designed to search for macroscopic dark matter (macros) through coherent acoustic disturbance…
Dark Energy in the Plane
Oem Trivedi, Robert J. Scherrer, Alfredo Gurrola
We introduce a unified framework for dark energy diagnostics based on the joint phase space of the equation of state and the sound speed . The resulting plane…
Solar System Probes for Scalar Field Dark Matter
Edmund Ghampson, Oem Trivedi, Robert J. Scherrer +1
Scalar field dark matter provides us with a well motivated alternative to conventional particle dark matter, especially when ultralight fields form coherent oscillations or compact…
Apocalypse When? Solar System Constraints on an Imminent Big Rip
Robert J. Scherrer, Oem Trivedi
Phantom dark energy models with an equation of state parameter lead generically to a future big rip singularity, in which the dark energy density becomes infinite in a fin…
Probing Dark Energy on the Moon
Alfredo Gurrola, Robert J. Scherrer, Oem Trivedi
The effective field theory (EFT) of cosmic acceleration provides a model-independent framework for describing dark energy and modified gravity, yet many of its defining operators r…
Partial Relief of the Hubble Tension and a Natural Self-Interacting Dark Matter Candidate From Staged Symmetry Breaking
Zachary J. Hoelscher, Thomas W. Kephart, Robert J. Scherrer +1
The values of the Hubble constant () inferred from the cosmic microwave background (CMB) and local measurements via the distance ladder exhibit a tension. In thi…
Probing the Sound Speed of Dark Energy with a Lunar Laser Interferometer
Alfredo Gurrola, Robert J. Scherrer, Oem Trivedi
The sound speed of dark energy encodes fundamental information about the microphysics underlying cosmic acceleration, yet remains essentially unconstrained by existing observations…
DESI-Like Hubble Expansion From Staged Symmetry Breaking: Constraints on Renormalizable Models
Zachary J. Hoelscher, Thomas W. Kephart, Robert J. Scherrer +1
The Dark Energy Spectroscopic Instrument (DESI) second data release shows a moderate preference for dark energy with a time-varying equation of state parameter, suggesting that the…
Dark Matter from Holography
Oem Trivedi, Robert J. Scherrer
Previous studies have examined the holographic principle as a means of producing dark energy. Here we propose instead the possibility of holographic dark matter. In this case, dark…
Comparing the Spatial Correlation of Binary Black Hole Mergers to Large-Scale Structure through the Illustris Simulation
Shaniya Jarrett, Kelly Holley-Bockelmann, Robert J. Scherrer
Gravitational waves (GWs) have provided a new lens through which to view the universe beyond traditional electromagnetic methods. The upcoming space-based gravitational wave missio…
Gravitational Effects of a Small Primordial Black Hole Passing Through the Human Body
Robert J. Scherrer
The gravitational effects of a primordial black hole (PBH) passing through the human body are examined, with the goal of determining the minimum mass necessary to produce significa…
What do we learn by mapping dark energy to a single value of ?
Samuel S. Taylor, Robert J. Scherrer
We examine several dark energy models with a time-varying equation of state parameter, , to determine what information can be derived by fitting the distance modulus in such…
The long freeze: an asymptotically static universe from holographic dark energy
Samuel Blitz, Robert J. Scherrer, Oem Trivedi
We show that some holographic dark energy models can lead to a future evolution of the universe in which the scale factor is asymptotically constant, while $\dot a \rightarrow…
New perspectives on future rip scenarios with holographic dark energy
Oem Trivedi, Robert J. Scherrer
We explore the asymptotic future evolution of holographic dark energy (HDE) models, in which the density of the dark energy is a function of a cutoff scale . We develop a genera…
