Kavli Affiliate: Donald G. York | First 5 Authors: David V. Bowen, Todd M. Tripp, Edward B. Jenkins, Max Pettini, Doron Chelouche | Summary: We present an HST Cosmic Origins Spectrograph (COS) spectrum of the QSO SDSS J095109.12+330745.8 ($z_{em} = 0.645$) whose sightline passes through the SMC-like dwarf galaxy UGC 5282 ($M_B = -16.0$, $cz […]
Kavli Affiliate: Jeffrey McMahon | First 5 Authors: Zack Li, Sigurd Naess, Simone Aiola, David Alonso, John W. Appel | Summary: One of the most important checks for systematic errors in CMB studies is the cross correlation of maps made by independent experiments. In this paper we report on the cross correlation between maps from […]
Kavli Affiliate: Angela Olinto | First 5 Authors: Martin Elvis, Jon Arenberg, David Ballantyne, Mark Bautz, Charles Beichman | Summary: Astrophysics spans an enormous range of questions on scales from individual planets to the entire cosmos. To address the richness of 21st century astrophysics requires a corresponding richness of telescopes spanning all bands and all […]
Kavli Affiliate: Clarence Chang | First 5 Authors: Changjiang Liu, Vincent F. C. Humbert, Terence Bretz-Sullivan, Gensheng Wang, Deshun Hong | Summary: Amongst the rare-earth perovskite nickelates, LaNiO$_3$ (LNO) is an exception. While the former have insulating and antiferromagnetic ground states, LNO remains metallic and non-magnetic down to the lowest temperatures. It is believed that […]
Kavli Affiliate: Karen Byrum | First 5 Authors: Kevork Abazajian, Graeme Addison, Peter Adshead, Zeeshan Ahmed, Steven W. Allen | Summary: We provide an overview of the science case, instrument configuration and project plan for the next-generation ground-based cosmic microwave background experiment CMB-S4, for consideration by the 2020 Decadal Survey. | Search Query: ArXiv Query: […]
Kavli Affiliate: Luca Grandi | First 5 Authors: Daniel Ahlin, Boris Bauermeister, Jan Conrad, Robert Gardner, Luca Grandi | Summary: The XENON experiment is looking for non-baryonic particle dark matter in the universe. The setup is a dual phase time projection chamber (TPC) filled with 3200 kg of ultra-pure liquid xenon. The setup is operated […]
Kavli Affiliate: Nickolay Gnedin | First 5 Authors: Enrico Garaldi, Nickolay Gnedin, Piero Madau, , | Summary: We investigate Lyman-$alpha$ transmission spikes at $z > 5$ in synthetic quasar spectra, and discuss their connection to the properties of the intergalactic medium and their ability to constrain reionization models. We use state-of-the-art radiation-hydrodynamic simulations from the […]
Kavli Affiliate: Alex Drlica Wagner | First 5 Authors: Martin Banda-Huarca, Julio Camargo, Josselin Desmars, Ricardo Ogando, Roberto Vieira-Martins | Summary: Transneptunian objects (TNOs) are a source of invaluable information to access the history and evolution of the outer solar system. However, observing these faint objects is a difficult task. As a consequence, important properties […]
Kavli Affiliate: Donald G. York | First 5 Authors: Ryan J. Oelkers, Lucas M. Macri, Lifan Wang, Michael C. B. Ashley, Xiangqun Cui | Summary: The Chinese Small Telescope ARray (CSTAR) carried out high-cadence time-series observations of 20.1 square degrees centered on the South Celestial Pole during the 2008, 2009 & 2010 winter seasons from […]
Kavli Affiliate: Juan I. Collar | First 5 Authors: Craig E. Aalseth, Juan I. Collar, Jim Colaresi, James E. Fast, Todd W. Hossbach | Summary: Recent progress on the development of very low noise high purity germanium ionization spectrometers has produced an instrument of 1.2 kg mass and excellent noise performance. The detector was installed […]
