The Impact of Splashback Galaxies on Galaxy Assembly Bias
Hernan Rincon, Idit Zehavi, Sergio Contreras +2
The clustering of galaxies is affected by the assembly history of their underlying dark matter halos. This complex phenomenon, known as galaxy assembly bias, has been extensively s…
Secondary Dependence of Baryonic Effects on the Density Profile of Dark Matter Halos
Yikun Wang, Idit Zehavi, Sergio Contreras +3
Baryonic physics is anticipated to be a major source of systematic uncertainty in current and future large-scale cosmological surveys. We investigate how baryonic effects on halo d…
Gradient-Produced Neutrinos
Erwin H. Tanin, Yikun Wang
Sufficiently strong electric fields can produce charged-particle pairs via the Schwinger effect. We argue that steep matter-density gradients, as can arise in neutron star interior…
Detecting gravitational signatures of dark matter with atom gradiometers
Leonardo Badurina, Yufeng Du, Vincent S. H. Lee +2
We study the purely gravitational signatures of dark matter from the ultralight to the ultraheavy mass range in proposed long-baseline atom gradiometers, focusing on terrestrial de…
A New Measure of Assembly Bias using the Environment Dependence of the Luminosity Function
Yikun Wang, Idit Zehavi, Sergio Contreras +2
Assembly bias is the variation in the clustering of dark matter halos and galaxies that arises from correlations between the halo assembly history and the large-scale environment a…
Signatures of linearized gravity in atom interferometers: A simplified computational framework
Leonardo Badurina, Yufeng Du, Vincent S. H. Lee +2
We develop a general framework for calculating the leading-order, general relativistic contributions to the gravitational phase shift in single-photon atom interferometers within t…
