Kavli Affiliate: Rebecca Masterson | First 5 Authors: Branden Allen, Jonathan Grindlay, Jaesub Hong, Richard P. Binzel, Rebecca Masterson | Summary: The OSIRIS-REx Mission was selected under the NASA New Frontiers program and is scheduled for launch in September of 2016 for a rendezvous with, and collection of a sample from the surface of asteroid […]
Kavli Affiliate: Alan Levine | First 5 Authors: Saul Rappaport, Roberto Sanchis-Ojeda, Leslie A. Rogers, Alan Levine, Joshua N. Winn | Summary: The requirement that a planet must orbit outside of its Roche limit gives a lower limit on the planet’s mean density. The minimum density depends almost entirely on the orbital period and is […]
Kavli Affiliate: Erotokritos Katsavounidis | First 5 Authors: Rahul Biswas, Lindy Blackburn, Junwei Cao, Reed Essick, Kari Alison Hodge | Summary: The sensitivity of searches for astrophysical transients in data from the LIGO is generally limited by the presence of transient, non-Gaussian noise artifacts, which occur at a high-enough rate such that accidental coincidence across […]
Kavli Affiliate: John W. Belcher | First 5 Authors: Richard H. Price, John W. Belcher, David A. Nichols, , | Summary: We compare the nature of electromagnetic fields and of gravitational fields in linearized general relativity. We carry out this comparison both mathematically and visually. In particular the "lines of force" visualizations of electromagnetism are […]
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: 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 […]
Kavli Affiliate: Tom Chang | First 5 Authors: Sunny W. Y. Tam, Tom Chang, Paul M. Kintner, Eric M. Klatt, | Summary: Rank-Ordered Multifractal Analysis (ROMA), a recently developed technique that combines the ideas of parametric rank ordering and one parameter scaling of monofractals, has the capabilities of deciphering the multifractal characteristics of intermittent fluctuations. […]
Kavli Affiliate: Catherine Grant | First 5 Authors: Eric D. Miller, Marshall Bautz, Catherine Grant, Ryan Hickox, Mark Brodwin | Summary: Galaxy groups are key tracers of galaxy evolution, cluster evolution, and structure formation, yet they are difficult to study at even moderate redshift. We have undertaken a project to observe a flux-limited sample of […]
Kavli Affiliate: Alan Levine | First 5 Authors: Martin Durant, Remon Cornelisse, Ron Remillard, Alan Levine, | Summary: Regular observations by the All Sky Monitor aboard the Rossi X-ray Timing Explorer satellite have yielded well-sampled light-curves with a time baseline of over ten years. We find that up to eight of the sixteen brightest persistent […]
