BUILDING TECHNOLOGIES FOR THE FUTURE OF SPACE SCIENCES
I recently updated a video I’ve been showing for the last few years in public talks on exoplanets. This shows the current population of known exoplanets, in order of discovery and coded by discovery method.
The code to generate this video is available at: https://github.com/dsavransky/miscpy/blob/master/Animaitons/exoplanet_history_anim.py
Data is from the NASA Exoplanet Archive (http://exoplanetarchive.ipac.caltech.edu/).
SIOSLab attended the 2017 Sibley Graduate Research Symposium (SGRS) held in Upson Hall at Cornell University on January 20th, 2017. Joyce Fang presented her talk titled “Misalignment Retrieval of an Off-axis Parabolic Mirror using Kalman Filtering.” Jacob Shapiro presented his talk titled “Improved Signal Detection in Direct Imaging of Exoplanets.” Gabriel Soto presented his talk titled “Starshade Orbital Maneuver Study for WFIRST.”
SIOSLab attended the 229th AAS Meeting in Grapevine, Texas earlier this month. Daniel Garrett presented his poster titled “Analytical Methods for Exoplanet Imaging Detection Metrics.” Jacob Shapiro and Nikhil Ranganathan presented their poster titled “Blind Source Separation Algorithms for PSF Subtraction from Direct Imaging.” Gabriel Soto presented his poster titled “Starshade Orbital Maneuver Study for WFIRST.”
As part of her recent visit to the Sibley School, NASA deputy administrator Dava Newman stopped by SIOSlab to hear about our work. We were all very excited to share our research, especially as so much of our support comes from NASA. Many thanks to Dr. Newman, Danielle Wood, Ana Diaz Artiles and everyone involved in making her visit here a great success.

Our new paper “Automated alignment of a reconfigurable optical system using focal-plane sensing and Kalman filtering” has been published in OSA Applied Optics DOI.
Our new paper titled “Analytical formulation of the single-visit completeness joint probability density function” has been published in The Astrophysical Journal. The paper can be accessed through DOI.
Joyce Fang successfully passed her A exam on Monday April 19th, marking her entrance into the dissertation phase of her degree program.
On February 29 – March 2, we attended the international meeting Community Astrophysics with WFIRST: Guest Observer and Archival Science in Pasadena, followed by the WFIRST Preparatory Science team meeting on March 3. Christian D. presented a poster and Dmitry S. gave a talk on science modeling for the WFIRST coronagraph.
