Kavli Affiliate: Catherine Grant | First 5 Authors: Xiaobo Li, Shu Zhang, Catherine Grant, Matteo Guainazzi, Eric Miller | Summary: We summarize the outcome of the 10th meeting of the International Astronomical Consortium for High Energy Calibration (IACHEC), held in Beijing (People’s Republic of China) in April 2015. Over 80 scientists directly involved in the […]
Kavli Affiliate: Masaki Yamashita | First 5 Authors: Masaki Yamashita, , , , | Summary: XMASS-I uses single phase liquid xenon technology for aiming at the direct detection of dark matter. The detector observes only scintillation light by 2 inch 642 PMTs which are placed in sphere shape around an active volume. With its large […]
Kavli Affiliate: Robert Byer | First 5 Authors: Shailendar Saraf, Paul Berceau, Alberto Stochino, Robert Byer, John Lipa | Summary: We report on an ultrastable molecular clock based on the interrogation of the 3{nu} rotational-vibrational combination band at 1563nm of carbon monoxide 12C16O. The laser stabilization scheme is based on frequency modulation (FM) saturation spectroscopy […]
Kavli Affiliate: Kiyoshi Wesley Masui | First 5 Authors: Kiyoshi Wesley Masui, Kris Sigurdson, , , | Summary: We propose that "standard pings", brief broadband radio impulses, can be used to study the three-dimensional clustering of matter in the Universe even in the absence of redshift information. The dispersion of radio waves as they travel […]
Kavli Affiliate: Robert Goeke | First 5 Authors: Natasha Hurley-Walker, Melanie Johnston-Hollitt, Ron Ekers, Richard Hunstead, Elaine M. Sadler | Summary: Recent observations with the Murchison Widefield Array at 185~MHz have serendipitously unveiled a heretofore unknown giant and relatively nearby ($z = 0.0178$) radio galaxy associated with NGC,1534. The diffuse emission presented here is the […]
Kavli Affiliate: Philip J. Marshall | First 5 Authors: Rachel Mandelbaum, Barnaby Rowe, Robert Armstrong, Deborah Bard, Emmanuel Bertin | Summary: We present first results from the third GRavitational lEnsing Accuracy Testing (GREAT3) challenge, the third in a sequence of challenges for testing methods of inferring weak gravitational lensing shear distortions from simulated galaxy images. […]
Kavli Affiliate: Rebecca A. Masterson | First 5 Authors: Niraj K. Inamdar, Richard P. Binzel, Jae Sub Hong, Branden Allen, Jonathan Grindlay | Summary: OSIRIS-REx is the third spacecraft in the NASA New Frontiers Program and is planned for launch in 2016. OSIRIS-REx will orbit the near-Earth asteroid (101955) Bennu, characterize it, and return a […]
Kavli Affiliate: Peter G. Ford | First 5 Authors: Catherine E. Grant, Mark W. Bautz, Peter G. Ford, Paul P. Plucinsky, | Summary: As the Advanced CCD Imaging Spectrometer (ACIS) on the Chandra X-ray Observatory enters its fifteenth year of operation on orbit, it continues to perform well and produce spectacular scientific results. The response […]
Kavli Affiliate: Steven Kahn | First 5 Authors: Andrew Rasmussen, Pierre Antilogus, Pierre Astier, Chuck Claver, Peter Doherty | Summary: Near-future astronomical survey experiments, such as LSST, possess system requirements of unprecedented fidelity that span photometry, astrometry and shape transfer. Some of these requirements flow directly to the array of science imaging sensors at the […]
Kavli Affiliate: Kentaro Hori | First 5 Authors: Kentaro Hori, Heeyeon Kim, Piljin Yi, , | Summary: We compute the Witten index of one-dimensional gauged linear sigma models with at least ${mathcal N}=2$ supersymmetry. In the phase where the gauge group is broken to a finite group, the index is expressed as a certain residue […]
