The ArgusSpec Prototype: Autonomous Spectroscopic Follow-up of Flares Detected by Large Array Telescopes
Nathan W. Galliher, Thomas Procter, Nicholas M. Law +7
ArgusSpec is a prototype autonomous spectroscopic follow-up instrument designed to characterize flares detected by the Argus Pathfinder telescope array by taking short exposure (30…
The Evryscope Fast Transient Engine: Real-Time Detection for Rapidly Evolving Transients
Hank Corbett, Jonathan Carney, Ramses Gonzalez +8
Astrophysical transients with rapid development on sub-hour timescales are intrinsically rare. Due to their short durations, events like stellar superflares, optical flashes from g…
Packing the sky: coverage optimization and evaluation for large telescope arrays
Nathan W. Galliher, Nicholas M. Law, Hank Corbett +3
Recent advancements in low-cost astronomical equipment, including high-quality medium-aperture telescopes and low-noise CMOS detectors, have made the deployment of large optical te…
The inside-out, upside-down telescope: the Argus Array's new pseudofocal design
Nicholas Law, Alan Vasquez Soto, Hank Corbett +4
The Argus Optical Array will be the first all-sky, arcsecond-resolution, 5-m class telescope. The 55 GPix Array, currently being prototyped, will consist of 900 telescopes with 61…
The sky at one terabit per second: Architecture and implementation of the Argus Array Hierarchical Data Processing System
Hank Corbett, Alan Vasquez Soto, Lawrence Machia +3
The Argus Optical Array is a synoptic survey observatory, currently in development, that will have a total collecting area equivalent to a 5-meter monolithic telescope and an all-s…
Low-Cost Access to the Deep, High-Cadence Sky: the Argus Optical Array
Nicholas M. Law, Hank Corbett, Nathan W. Galliher +16
New mass-produced, wide-field, small-aperture telescopes have the potential to revolutionize ground-based astronomy by greatly reducing the cost of collecting area. In this paper,…
Rotation periods of TESS Objects of Interest from the Magellan-TESS Survey with multiband photometry from Evryscope and TESS
Ward S. Howard, Johanna Teske, Hank Corbett +8
Stellar RV jitter due to surface activity may bias the RV semi-amplitude and mass of rocky planets. The amplitude of the jitter may be estimated from the uncertainty in the rotatio…
Revisiting the HD 21749 Planetary System with Stellar Activity Modeling
Tianjun Gan, Sharon Xuesong Wang, Johanna K. Teske +26
HD 21749 is a bright ( mag) K dwarf at 16 pc known to host an inner terrestrial planet HD 21749c as well as an outer sub-Neptune HD 21749b, both delivered by TESS. Follow-up…
Orbital Foregrounds for Ultra-Short Duration Transients
Hank Corbett, Nicholas M. Law, Alan Vasquez Soto +7
Reflections from objects in Earth orbit can produce sub-second, star-like optical flashes similar to astrophysical transients. Reflections have historically caused false alarms for…
EvryFlare III: Temperature Evolution and Habitability Impacts of Dozens of Superflares Observed Simultaneously by Evryscope and TESS
Ward S. Howard, Hank Corbett, Nicholas M. Law +8
Superflares may provide the dominant source of biologically relevant UV radiation to rocky habitable zone M-dwarf planets (M-Earths), altering planetary atmospheres and conditions…
Automatic Translation of tock-CSP into Timed Automata
Abdulrazaq Abba, Ana Cavalcanti, Jeremy Jacob
The process algebra tock-CSP provides textual notations for modelling discrete-time behaviours, with the support of various tools for verification. Similarly, automatic verificatio…
Hot Subdwarf All Southern Sky Fast Transit Survey with the Evryscope
Jeffrey K. Ratzloff, Brad N. Barlow, Peter Nemeth +6
We have conducted a survey of candidate hot subdwarf stars in the southern sky searching for fast transits, eclipses, and sinusoidal like variability in the Evryscope light curves.…
Dynamical regimes of vortex flow in type-II superconductors with parallel twin boundaries
Harshwardhan Chaturvedi, Nathan Galliher, Ulrich Dobramysl +2
We explore the dynamics of driven magnetic flux lines in disordered type-II superconductors in the presence of twin boundaries oriented parallel to the direction of the applied mag…
