Novelty Detection on Radio Astronomy Data using Signatures
arXiv.orgWe introduce SigNova, a new semi-supervised framework for detecting anomalies in streamed data. While our initial examples focus on detecting radio-frequency interference (RFI) in digitized signals within the field of radio astronomy, it is important to ...

The future of astronomy with small satellites
Nature Astronomy, 2020The number of small satellites has grown hugely in the past decade, from tens of satellites per year in the mid-2010s to a projection of tens of thousands in orbit by the mid-2020s.

AstroPT: Scaling Large Observation Models for Astronomy
arXiv.orgThis work presents AstroPT, an autoregressive pretrained transformer developed with astronomical use-cases in mind. The AstroPT models presented here have been pretrained on 8.6 million $512 \times 512$ pixel $grz$-band galaxy postage stamp observations ...

Astronomy is fundamentally an observational science and as such it is important for astronomers and astrophysicists to understand how their data are collected and analyzed. This book is a comprehensive review of current observational techniques and instruments. Featuring instruments such as Spitzer, Herschel, Fermi, ALMA, Super-Kamiokande, SNO, IceCube,

Observational properties of thermonuclear supernovae
Nature Astronomy, 2019The explosive death of a star as a supernova is one of the most dramatic events in the Universe. Supernovae have an outsized impact on many areas of astrophysics: they are major contributors to the chemical enrichment of the cosmos and significantly ...

Theoretical astronomy and observation
Physics Bulletin, 1972Theoretical astronomy is in a phase of seeking to explain recent observations by existing theory – thereby testing the theory – rather than constructing much new general theory. The failure of the latest attempts to detect neutrinos from the sun poses serious problems.
