Design, Implementation, and Performance of the Primary Reflector for SALTUS
Jonathan W. Arenberg, Leon K. Harding, Bob Chang +8
The Single Aperture Large Telescope for Universe Studies (SALTUS) is a mission concept for a far-infrared observatory developed under the recent Astrophysics Probe Explorer opportu…
A Roadmap For Scientific Ballooning 2020-2030
Peter Gorham, James Anderson, Pietro Bernasconi +8
From 2018 to 2020, the Scientific Balloon Roadmap Program Analysis Group (Balloon Roadmap PAG) served as an community-based, interdisciplinary forum for soliciting and coordinating…
Simulated Molecular Gas Emission in Galaxy Mergers with Embedded AGN
Desika Narayanan, Thomas J. Cox, Brant Robertson +6
We investigate the effect of embedded active galactic nuclei (AGN) in galaxy mergers on the CO molecular line emission by combining non-local thermodynamic equilibrium (LTE) radiat…
A tabletop x-ray tomography instrument for nanometer-scale imaging: demonstration of the 1,000-element transition-edge sensor subarray
Paul Szypryt, Nathan Nakamura, Daniel T. Becker +28
We report on the 1,000-element transition-edge sensor (TES) x-ray spectrometer implementation of the TOMographic Circuit Analysis Tool (TOMCAT). TOMCAT combines a high spatial reso…
SALTUS Probe Class Space Mission: Observatory Architecture and Mission Design
Leon K. Harding, Jonathan W. Arenberg, Benjamin Donovan +10
We describe the space observatory architecture and mission design of the SALTUS mission, a NASA Astrophysics Probe Explorer concept. SALTUS will address key far-infrared science us…
A Categorification of Hall Algebras
Christopher Walker
In recent years, there has been great interest in the study of categorification, specifically as it applies to the theory of quantum groups. In this thesis, we would like to provid…
