Edge of darkness: The splashback radius as a physical halo boundary The radii and masses of dark matter halos are an essential input for models of galaxy formation, and for the interpretation of numerous observations. These radii are typically defined through an arbitrary overdensity threshold, largely because the density profiles of halos are thought not to have a well-defined edge. In ...

Insights into Supermassive Black Hole Mergers, Stalling and Demographics with Pulsar Timing ArraysGalaxy mergers are a standard aspect of galaxy formation and evolution, and likely all large galaxies contain central supermassive black holes (SMBH). Here I discuss a new bottom-up approach to identifying continuous nanohertz gravitational wave (GW) host galaxies by using massive elliptical galaxies in the 2 Micron All Sky Survey, ...

Nanoscale Excitations in Space and TimeThe static and dynamic properties of matter depend largely on its inherent heterogeneity in the mass, charge, and spin distributions. Excitations within and coupling of matter to its environment would be expected to exhibit spatial and temporal dependences. Because matter is assembled from individual atoms and molecules, a viable approach ...
Neutrinos are the most numerous matter particles in the universe, but the least understood.
