We introduce a bang-bang shortcut to adiabaticity for the Dicke model, which we implement via a two-dimensional array of trapped ions in a Penning trap with a spin-dependent force detuned close to the center-of-mass drumhead mode. Our focus is on emp

Trapped ions are sensitive detectors of weak forces and electric fields that excite ion motion. Here measurements of the center-of-mass motion of a trapped-ion crystal that are phase coherent with an applied weak external force are reported. These ex

We present preliminary analysis of new HST observations of the transiting extrasolar planet HD 209458b. Photometric observations were obtained with the Fine Guidance Sensor (FGS) on the Hubble Space Telescope (HST), providing milli-mag precision and

While HST’s planning and scheduling processes are mature, JWST’s–with a planned 2018 launch–are still in development. The STScI science, engineering, software, and operations teams are working together to get the JWST planning and scheduling

The observer program implementation, planning, and scheduling subsystems are undergoing software development for the James Webb Space Telescope front-end ground segment and are being tested in an integrated fashion. This part of the ground system lev

Architecture choices impact planning and scheduling of activity sequences for two widely separated spacecraft envisioned to be part of an astrophysics mission to observe extra-solar-planets. The two spacecraft consist of a large space telescope and a

A starshade with the James Webb Space Telescope (JWST) is the only possible path forward in the next decade to obtain images and spectra of a planet similar to the Earth, to study its habitability, and search for signs of alien life. While JWST was n

Analysis of the genome ofFrancisella tularensishas revealed few regulatory systems, and how the organism adapts to conditions in different niches is poorly understood. The stringent response is a global stress response mediated by (p)ppGpp. The enzym

The James Webb Space Telescope will be an extraordinary observatory, providing a huge range of exciting new astrophysical results. However, by itself it will not be capable of directly imaging planets in the habitable zone of nearby stars, one of the
