Taut sutured handlebodies as twisted homology products

Friedl and Kim show any taut sutured manifold can be realized as a twisted homology product, but their proof gives no practical description of how complicated the realizing representation needs to be. We give a number of results illustrating the relationship between the topology of a taut sutured handlebody and the complexity of a representation realizing it as a homology product

BLS Spotlight on Statistics: Expenditures on Admissions to the Arts, Movies, Sporting Events, and other Entertainment

In 2015, American consumers spent an average of $652 on admissions to the arts, movies, sporting events, and other entertainment and recreational activities. In 2012, 70 percent of U.S. adults attended a live performing arts or sporting event or went to the movies. This Spotlight on Statistics uses data from the Consumer Expenditure Survey and the Survey of Public Participation in the Arts to profile consumer spending and attendance at arts, sports, and entertainment events.For additional context, the Spotlight also examines selected personal consumption expenditure estimates from the Arts and Cultural Production Satellite Account

Exploring the Edge of Our Solar System: IBEX Mission (Poster)

This poster outlines the major mission highlights of the Interstellar Boundary Explorer (IBEX) mission, a Small Explorer Earth-orbiting spacecraft that is designed to map the distant boundary between the solar wind from our Sun and the interstellar medium. This poster supports a full-length planetarium show about the IBEX mission and the boundary of the Solar System. Each short activity/product helps to build awareness and engagement in the science and engineering aspects of the mission that are reinforced as visitors choose to participate in more activities, including viewing the show and mission website.

Candidates for detecting exoplanetary radio emissions generated by magnetosphere-ionosphere coupling

In this paper we consider the magnetosphere-ionosphere (M-I) coupling at Jupiter-like exoplanets with internal plasma sources such as volcanic moons, and we have determined the best candidates for detection of these radio emissions by estimating the maximum spectral flux density expected from planets orbiting stars within 25 pc using data listed in the NASA/IPAC/NExScI Star and Exoplanet Database (NStED). In total we identify 91 potential targets, of which 40 already host planets and 51 have stellar X-ray luminosity 100 times the solar value. In general, we find that stronger planetary field strength, combined with faster rotation rate, higher stellar XUV luminosity, and lower stellar wind dynamic pressure results in higher radio power. The top two targets for each category are $\epsilon$ Eri and HIP 85523, and CPD-28 332 and FF And.Comment: Accepted for publication in Monthly Notices of the Royal Astronomical Society Letter
