Electromagnetic probes of primordial black holes as dark matter

Kavli Affiliate: A. C. Davis | First 5 Authors: Y. Ali-Haimoud, S. Clesse, J. Garcia-Bellido, A. Kashlinsky, L. Wyrzykowski | Summary: The LIGO discoveries have rekindled suggestions that primordial black holes (BHs) may constitute part to all of the dark matter (DM) in the Universe. Such suggestions came from 1) the observed merger rate of […]

Molecular gas in three z~7 quasar host galaxies

Kavli Affiliate: R. G. McMahon | First 5 Authors: Bram Venemans, Fabian Walter, Roberto Decarli, Carl Ferkinhoff, Axel Weiss | Summary: We present ALMA band 3 observations of the CO(6-5), CO(7-6), and [CI] 369micron emission lines in three of the highest redshift quasar host galaxies at 6.6<z<6.9. These measurements constitute the highest-redshift CO detections to […]

The compact, ~1 kpc host galaxy of a quasar at z=7.1

Kavli Affiliate: R. G. McMahon | First 5 Authors: Bram Venemans, Fabian Walter, Roberto Decarli, Eduardo Banados, Jacqueline Hodge | Summary: We present ALMA observations of the [CII] fine structure line and the underlying far-infrared (FIR) dust continuum emission in J1120+0641, the most distant quasar currently known (z=7.1). We also present observations targeting the CO(2-1), […]

Discovery of a z=0.65 Post-Starburst BAL Quasar in the DES Supernova Fields

Kavli Affiliate: R. G. McMahon | First 5 Authors: Dale Mudd, Paul Martini, Suk Sien Tie, Chris Lidman, Richard McMahon | Summary: We present the discovery of a z=0.65 low-ionization broad absorption line (LoBAL) quasar in a post-starburst galaxy in data from the Dark Energy Survey (DES) and spectroscopy from the Australian Dark Energy Survey […]

Planck 2013 results X. Energetic particle effects: characterization, removal, and simulation

Kavli Affiliate: E. P. S. Shellard | First 5 Authors: Planck Collaboration, P. A. R. Ade, N. Aghanim, C. Armitage-Caplan, M. Arnaud | Summary: We describe the detection, interpretation, and removal of the signal resulting from interactions of high energy particles with the Planck High Frequency Instrument (HFI). There are two types of interactions: heating […]

Particle Physics Models, Topological Defects and Electroweak Baryogenesis

Kavli Affiliate: A. C. Davis | First 5 Authors: M. Trodden, A-C. Davis, R. Brandenberger, , | Summary: We demonstrate the viability of electroweak baryogenesis scenarios in which the necessary departure from equilibrium is realized by the evolution of a network of topological defects. We consider several effective models of TeV physics, each addressing a […]
