Kavli Affiliate: Gordan Z. Krnjaic | First 5 Authors: David E. Kaplan, Gordan Z. Krnjaic, Keith R. Rehermann, Christopher M. Wells, | Summary: We present a simple UV completion of Atomic Dark Matter (aDM) in which heavy right-handed neutrinos decay to induce both dark and lepton number densities. This model addresses several outstanding cosmological problems: […]
Kavli Affiliate: Gordan Z. Krnjaic | First 5 Authors: Bogdan A. Dobrescu, Gordan Z. Krnjaic, , , | Summary: We extend the standard model to include a weak-triplet and color-octet scalar. This `octo-triplet’ field consists of three particles, two charged and one neutral, whose masses and renormalizable interactions depend only on two new parameters. The […]

Kavli Affiliate: Mark SubbaRao | First 5 Authors: K. Simon Krughoff, Andrew Connolly, Joshua Frieman, Mark SubbaRao, Gary Kilper | Summary: Supernova rates are directly coupled to high mass stellar birth and evolution. As such, they are one of the few direct measures of the history of cosmic stellar evolution. In this paper we describe […]

Kavli Affiliate: Stephan Meyer | First 5 Authors: Lawrence Krauss, Scott Dodelson, Stephan Meyer, , | Summary: The observation of primordial gravitational waves could provide a new and unique window on the earliest moments in the history of the universe, and on possible new physics at energies many orders of magnitude beyond those accessible at […]
Kavli Affiliate: Mark U. SubbaRao | First 5 Authors: Donald P. Schneider, Gordon T. Richards, Patrick B. Hall, Michael A. Strauss, Scott F. Anderson | Summary: We present the fifth edition of the Sloan Digital Sky Survey (SDSS) Quasar Catalog, which is based upon the SDSS Seventh Data Release. The catalog, which contains 105,783 spectroscopically […]
Kavli Affiliate: Gordan Z. Krnjaic | First 5 Authors: David E. Kaplan, Gordan Z. Krnjaic, Keith R. Rehermann, Christopher M. Wells, | Summary: We propose that dark matter is dominantly comprised of atomic bound states. We build a simple model and map the parameter space that results in the early universe formation of hydrogen-like dark […]

Kavli Affiliate: Karen L. Byrum | First 5 Authors: Robert G. Wagner, Karen L. Byrum, Mayly Sanchez, Alexandre V. Vaniachine, Oswald Siegmund | Summary: We advocate support of research aimed at developing alternatives to the photomultiplier tube for photon detection in large astroparticle experiments such as gamma-ray and neutrino astronomy, and direct dark matter detectors.
