Mitigating Modal Noise in Multimode Circular Fibres by Optical Agitation using a Galvanometer
Supriyo Ghosh, Chantira Boonsri, William Martin +6
Modal noise appears due to the non-uniform and unstable distribution of light intensity among the finite number of modes in multimode fibres. It is an important limiting factor in…
Applied Machine-Learning Models to Identify Spectral Sub-Types of M Dwarfs from Photometric Surveys
Sirinrat Sithajan, Sukanya Meethong
M dwarfs are the most abundant stars in the Solar Neighborhood and they are prime targets for searching for rocky planets in habitable zones. Consequently, a detailed characterizat…
YSE-PZ: A Transient Survey Management Platform that Empowers the Human-in-the-Loop

Polarized Maser Emission with In-Source Faraday Rotation
Taylor L. Tobin, Malcolm D. Gray, Athol J. Kemball
We discuss studies of polarization in astrophysical masers with particular emphasis on the case where the Zeeman splitting is small compared to the Doppler profile, resulting in a…
The Gravitational-wave Optical Transient Observer (GOTO)
Martin J. Dyer, Kendall Ackley, Joe Lyman +12
The Gravitational-wave Optical Transient Observer (GOTO) is a wide-field telescope project focused on detecting optical counterparts to gravitational-wave sources. Each GOTO roboti…
Validation of standardized data formats and tools for ground-level particle-based gamma-ray observatories
A. Albert, R. Alfaro, J. C. Arteaga-Velázquez +74
Ground-based gamma-ray astronomy is still a rather young field of research, with strong historical connections to particle physics. This is why most observations are conducted by e…
The Gravitational-wave Optical Transient Observer (GOTO): prototype performance and prospects for transient science
