Kavli Affiliate: Craig J. Hogan | First 5 Authors: Craig J. Hogan, , , , | Summary: A model quantum system is proposed to describe position states of a massive body in flat space on large scales, excluding all standard quantum and gravitational degrees of freedom. The model is based on standard quantum spin commutators, […]
Kavli Affiliate: Robert A. Cameron | First 5 Authors: Markos Trichas, Paul J. Green, John D. Silverman, Tom Aldcroft, Wayne Barkhouse | Summary: From optical spectroscopy of X-ray sources observed as part of ChaMP, we present redshifts and classifications for a total of 1569 Chandra sources from our targeted spectroscopic follow up using the FLWO, […]
Kavli Affiliate: Sarah Church | First 5 Authors: Matthew Sieth, Sarah Church, Judy M. Lau, Patricia Voll, Todd Gaier | Summary: We report on the development of W-band (75-110 GHz) heterodyne receiver technology for large-format astronomical arrays. The receiver system is designed to be both mass-producible, so that the designs could be scaled to thousands […]
Kavli Affiliate: Geza Gyuk | First 5 Authors: Michael Solontoi, Mark Hammergren, Geza Gyuk, Andrew Puckett, | Summary: We present the spectra of 60 asteroids, including 47 V-types observed during the first phase of the Adler V-Type Asteroid (AVAST) Survey. SDSS photometry was used to select candidate V-type asteroids for follow up by nature of […]
Kavli Affiliate: Tomiyoshi Haruyama | First 5 Authors: Takashi Uchiyama, Shinji Miyoki, Souichi Telada, Kazuhiro Yamamoto, Masatake Ohashi | Summary: The thermal fluctuation of mirror surfaces is the fundamental limitation for interferometric gravitational wave (GW) detectors. Here, we experimentally demonstrate for the first time a reduction in a mirror’s thermal fluctuation in a GW detector […]
Kavli Affiliate: Norbert Schulz | First 5 Authors: Michael A. Nowak, Joern Wilms, Katja Pottschmidt, Norbert Schulz, Dipankar Maitra | Summary: We present three Suzaku observations of the black hole candidate 4U 1957+11 (V1408 Aql) — a source that exhibits some of the simplest and cleanest examples of soft, disk-dominated spectra. 4U 1957+11 also presents […]
Kavli Affiliate: Toshitake Kohno | First 5 Authors: Louis Funar, Toshitake Kohno, , , | Summary: We prove that, except for a few explicit roots of unity, the quantum image of any Johnson subgroup of the mapping class group contains an explicit free non-abelian subgroup. | Search Query: ArXiv Query: search_query=au:”Toshitake Kohno”&id_list=&start=0&max_results=3 Read More
Kavli Affiliate: Yukari Ito | First 5 Authors: Akira Ishii, Yukari Ito, Álvaro Nolla de Celis, , | Summary: In this paper we consider the iterated G-equivariant Hilbert scheme G/N-Hilb(N-Hilb) and prove that G/N-Hilb(N-Hilb(C^3)) is a crepant resolution of C^3/G isomorphic to the moduli space of theta-stable representations of the McKay quiver for certain stability […]
Kavli Affiliate: Paul Schechter | First 5 Authors: James Green, Paul Schechter, Charles Baltay, Rachel Bean, David Bennett | Summary: In December 2010, NASA created a Science Definition Team (SDT) for WFIRST, the Wide Field Infra-Red Survey Telescope, recommended by the Astro 2010 Decadal Survey as the highest priority for a large space mission. The […]
Kavli Affiliate: John W. Belcher | First 5 Authors: Stanislaw Olbert, John W. Belcher, Richard H. Price, , | Summary: We present a new algorithm for computing the electromagnetic fields of currents inside and outside of finite current sources, for arbitrary time variations in the currents. Unexpectedly, we find that our solutions for these fields […]
