Gravitational Wave Sources from New Physics
Craig J. Hogan
Forthcoming advances in direct gravitational wave detection from kilohertz to nanohertz frequencies have unique capabilities to detect signatures from or set meaningful constraints…
Astrophysical Effects of Scalar Dark Matter Miniclusters
Kathryn M. Zurek, Craig J. Hogan, Thomas R. Quinn
We model the formation, evolution and astrophysical effects of dark compact Scalar Miniclusters (``ScaMs''). These objects arise when a scalar field, with an axion-like or Higgs-li…
Gravitational Waves from Light Cosmic Strings: Backgrounds and Bursts with Large Loops
Craig J. Hogan
The mean spectrum and burst statistics of gravitational waves produced by a cosmological population of cosmic string loops are estimated using analytic approximations, calibrated w…
Hubble Imaging Excludes Cosmic String Lens
Eric Agol, Craig J. Hogan, Richard M. Plotkin
The galaxy image pair CSL-1 has been a leading candidate for a cosmic string lens. High quality imaging data from the Hubble Space Telescope presented here show that it is not a le…
Nuclear Astrophysics of Worlds in the String Landscape
Craig J. Hogan
Motivated by landscape models in string theory, cosmic nuclear evolution is analyzed allowing the Standard Model Higgs expectation value w to take values different from that in our…
