Precision long-term measurements of beta-decay-rate ratios in a controlled environment
S. D. Bergeson, J. B. Peatross, M. Ware
We report on measurements of relative beta-decay rates of Na-22, Cl-36, Co-60, Sr-90, Cs-137 monitored for more than one year. The radioactive samples are mounted in an automated s…
Space Telescope and Optical Reverberation Mapping Project VI: reverberating Disk Models for NGC 5548
D. Starkey, Keith Horne, M. M. Fausnaugh +90
We conduct a multiwavelength continuum variability study of the Seyfert 1 galaxy NGC 5548 to investigate the temperature structure of its accretion disk. The 19 overlapping continu…
A Deep Proper Motion Catalog Within the Sloan Digital Sky Survey Footprint. II. The White Dwarf Luminosity Function
Jeffrey A. Munn, Hugh C. Harris, Ted von Hippel +8
A catalog of 8472 white dwarf (WD) candidates is presented, selected using reduced proper motions from the deep proper motion catalog of Munn et al. 2014. Candidates are selected i…
A Bayesian Analysis of the Ages of Four Open Clusters
Elizabeth J. Jeffery, Ted von Hippel, David A. van Dyk +4
In this paper we apply a Bayesian technique to determine the best fit of stellar evolution models to find the main sequence turn off age and other cluster parameters of four interm…
The Short Rotation Period of Hi'iaka, Haumea's Largest Satellite
Danielle M. Hastings, Darin Ragozzine, Daniel C. Fabrycky +5
Hi'iaka is the larger outer satellite of the dwarf planet Haumea. Using relative photometry from the Hubble Space Telescope and Magellan and a phase dispersion minimization analysi…
Measurement of the Yb I transition frequency at 399 nm using an optical frequency comb
Michaela Kleinert, M. E. Gold Dahl, Scott D. Bergeson
We determine the frequency of the Yb I transition at 399 nm using an optical frequency comb. Although this transition was measured previously using an optical trans…
