Collaboration and Competition in Exoplanet Research
Collaboration and competition are strong driving forces in the modern search for exoplanets, appears between individuals, agencies and nations as well as between observing techniques and theoretical interpretation. I will argue that these forces, taken in balance, are beneficial to the field and are partly responsible for the rapid progress in the search for planets and ultimately the search for life beyond the solar system. Specific examples will include indirect detection of Earth analogs from ground and space and the direct detection of gas giant and terrestrial planets.
Modeling the white light fringe
This paper addresses the issue of modeling the white light fringe.
Tracking the moving optical photocenters of active galaxies: binary black holes, accretion disks and relativistic jets
We will use the astrometric capabilities of the Space Interferometry Mission to answer three key questions about active galactic nuclei: 1) Does the separation of the radio core and optical photocenter of quasars change on the same timescale as their photometric variability? 2) Does the most compact optical emission from an active galactic nucleus come from an accretion disk or from a relativistic jet? and 3) Do the cores of galaxies harbor binary supermassive black holes remaining from galaxy mergers?
SIM science operations
This paper describes the science scheduling and operation of the Space Interferometry Mission (SIM) as a science instrument
SIM internal metrology beam launcher development
In this paper, we present some of the experimental results from a laboratory demonstration unit and design considerations for SIM's internal metrology beam launcher.
The Space Interferometry Mission
In this paper we outline the design of the SIM Instrument, and how it will be used in the search for extrasolar planets. We also briefly describe some selected topics from the SIM astrometric science program.
Progress in Design and Construction of the Optical Communications Telescope Laboratory (OCTL)
JPL is constructing an Optical Communications Telescope Laboratory (OCTL) at its Table Mountain Facility complex in the San Bernadino Mountains of Southern California.
Keck Interferometer: Progress Report
The Keck Interferometer is a NASA-funded joint development between JPL and the W.M. Keck Observatory.
The dependence of the Micro-Arcsecond Metrology (MAM) testbed performance prediction on white light algorithm approach
This paper will compare the performance of various algorithms using the MAM data, and will aid in our recommendation of how the SIM flight system should process the science and guide interferometer data.
The International Celestial Reference Frame as Realized by Very Long Baseline Interferometry
A quasi-inertial reference frame is defined based on the radio positions of 212 extragalactic sources distributed over the entire sky.
