Random Ramblings on Software Tools
Once in a while, we have a ‘tools’ discussion during group meetings to go over various research-adjacent software tools that can potentially make your life easier. In the latest iteration, we discussed version control with git, structuring portable filesystems with
SIOSlab at the Roman Coronagraph Instrument Information Sessions
Several of us presented at the recent Roman Coronagraph Instrument Information Sessions, held virtually on October 26th and 28th. Slides and recordings of all talks are available here. Also, check out the results of the Coronagraph Science Investigation Team at
SIOSlab Contributes to the Decadal Survey
Last week, the National Academies released the Astro2020 decadal survey in Astronomy and Astrophysics: Pathways to Discovery in Astronomy and Astrophysics for the 2020s. SIOSlab is proud to have contributed to the survey, alongside many of our colleagues at Cornell.
Autonomous Cross-Calibration for Imaging Satellites (ACCIS)
Presented by Zvonimir Stojanovski at the 2021 AAS/AIAA Astrodynamics Specialist Conference, August 11, 2021.
On Nutation Dampers
I’ve been teaching the theory of nutation dampers for years, and have finally gotten around to creating a good visualization of one. Nutation dampers are really neat devices for rejecting disturbances on spin-stabilized spacecraft. Essentially, a damper is any mechanical
On Detecting Exoplanets
Here is a lecture I recently did on techniques for the detection of exoplanets: A related video illustrating some of the methods:
On Space Telescopes
I recently had the opportunity to do a guest lecture on astronomy space missions. See below for some fun facts about Hubble and other space telescopes.
