Multi-sensor fusion for fine-guidance and milliarcsecond-level attitude estimation of balloon-borne telescope
Philippe Voyer, Maya Amit, Steven J. Benton +44
Balloon-borne telescopes rely on fine-guidance systems to achieve milliarcsecond image stability despite residual disturbances from the balloon environment. In these systems, the F…
Lensing in the Blue III: Weak Lensing Shape Catalogs of 30 Merging Galaxy Clusters
Sayan Saha, Jacqueline E. McCleary, Spencer W. Everett +38
We present the weak gravitational lensing dataset from the Super-pressure Balloon-Borne Imaging Telescope (SuperBIT), which imaged 30 galaxy clusters during its 45 night flight in…
A parameter scan of dark zone maintenance for high-contrast imaging of exoplanets using theoretical and experimental implementations
Saikrishna Manojkumar, Christine L. Page, Leonid Pogorelyuk +14
Maintaining wavefront stability while directly imaging exoplanets over long exposure times is an ongoing problem in the field of high-contrast imaging. Robust and efficient high-or…
SuperBIT Superpressure Flight Instrument Overview and Performance: Near diffraction-limited Astronomical Imaging from the Stratosphere
Ajay S. Gill, Steven J. Benton, Christopher J. Damaren +26
SuperBIT was a 0.5-meter near-ultraviolet to near-infrared wide-field telescope that launched on a NASA superpressure balloon into the stratosphere from New Zealand for a 45-night…
From SuperBIT to GigaBIT: Informing next-generation balloon-borne telescope design with Fine Guidance System flight data
Philippe Voyer, Steven J. Benton, Christopher J. Damaren +28
The Super-pressure Balloon-borne Imaging Telescope (SuperBIT) is a near-diffraction-limited 0.5m telescope that launched via NASA's super-pressure balloon technology on April 16, 2…
Hydrodynamical simulations of merging galaxy clusters: giant dark matter particle colliders, powered by gravity
Ellen L. Sirks, David Harvey, Richard Massey +7
Terrestrial particle accelerators collide charged particles, then watch the trajectory of outgoing debris - but they cannot manipulate dark matter. Fortunately, dark matter is the…
