Double-offset Cassegrain telescopes for the Ultraviolet Type Ia (UVIa) mission concept
Fernando Cruz Aguirre, Keri Hoadley, Curtis McCully +13
Our understanding of cosmology is shaped by Type Ia supernovae (SNe Ia), the runaway thermonuclear detonations of white dwarfs via accretion from a companion star. The nature of th…
The Ultraviolet Type Ia Supernova CubeSat (UVIa): Science Motivation & Mission Concept
Keri Hoadley, Curtis McCully, Gillian Kyne +23
The Ultraviolet (UV) Type Ia Supernova Mission (UVIa) is a CubeSat/SmallSat concept that stands to test critical space-borne UV technology for future missions like the Habitable Wo…
An upgraded 0.4-meter telescope fleet for Las Cumbres Observatory's Educational and Science Programs
Daniel-Rolf Harbeck, Brook Taylor, Annie Kirby +20
Las Cumbres Observatory (LCOGT) operates a global network of robotic 0.4, 1.0, and 2.0-meter telescopes to facilitate scientific research and education in time-domain astronomy. LC…
The Future of Astronomical Data Infrastructure: Meeting Report
Michael R. Blanton, Janet D. Evans, Dara Norman +69
The astronomical community is grappling with the increasing volume and complexity of data produced by modern telescopes, due to difficulties in reducing, accessing, analyzing, and…
SAGUARO: Time-domain Infrastructure for the Fourth Gravitational-wave Observing Run and Beyond
Griffin Hosseinzadeh, Kerry Paterson, Jillian C. Rastinejad +14
We present upgraded infrastructure for Searches after Gravitational Waves Using ARizona Observatories (SAGUARO) during LIGO, Virgo, and KAGRA's fourth gravitational-wave (GW) obser…
Automatic Spectroscopic Data Reduction using BANZAI
Curtis McCully, Matthew Daily, G. Mirek Brandt +3
Time domain astronomy has both increased the data volume and the urgency of data reduction in recent years. Spectra provide key insights into astrophysical phenomena but require co…
Cosmic-CoNN: A Cosmic Ray Detection Deep-Learning Framework, Dataset, and Toolkit
Chengyuan Xu, Curtis McCully, Boning Dong +2
Rejecting cosmic rays (CRs) is essential for the scientific interpretation of CCD-captured data, but detecting CRs in single-exposure images has remained challenging. Conventional…
Automatic Echelle Spectrograph Wavelength Calibration
G. M. Brandt, T. D. Brandt, C. McCully
Time domain astronomy and the increasing number of exoplanet candidates call for reliable, robust, and automatic wavelength calibration. We present an algorithm for wavelength cali…
Real-time processing of the imaging data from the network of Las Cumbres Observatory Telescopes using BANZAI
Curtis McCully, Nikolaus H. Volgenau, Daniel-Rolf Harbeck +5
Work in time-domain astronomy necessitates robust, automated data processing pipelines that operate in real time. We present the BANZAI pipeline which processes the thousands of sc…
Long-Term Monitoring of Throughput in Las Cumbres Observatory's Fleet of Telescopes
Daniel-Rolf Harbeck, Curtis McCully, Andrew Pickles +3
The Las Cumbres Observatory operates a fleet of robotically controlled telescopes currently two 2m, nine 1m, and ten 0.4m telescopes, distributed amongst six sites covering both he…
The Astropy Project: Building an inclusive, open-science project and status of the v2.0 core package
The Astropy Collaboration, A. M. Price-Whelan, B. M. Sipőcz +134
The Astropy project supports and fosters the development of open-source and openly-developed Python packages that provide commonly-needed functionality to the astronomical communit…
