An Efficient Shift-and-stack Algorithm Applied to Detection Catalogs Open
The boundary of solar system object discovery lies in detecting its faintest members. However, their discovery in detection catalogs from imaging surveys is fundamentally limited by the practice of thresholding detections at signal-to-nois…

Faint Solar System Object Discovery in Rubin Data with Parallax-Corrected Shift-and-Stack Open
The population of Trans-Neptunian Objects (TNOs) offers critical insights into the formation and dynamical evolution of the solar system and planetary systems elsewhere. Despite an estimated mass 20–100 times that of the asteroid belt, few…

The DECam Ecliptic Exploration Project (DEEP). VI. First Multiyear Observations of Trans-Neptunian Objects Open
We present the first set of trans-Neptunian objects (TNOs) observed on multiple nights in data taken from the DECam Ecliptic Exploration Project. Of these 110 TNOs, 105 do not coincide with previously known TNOs and appear to be new discov…

Sifting through the Static: Moving Object Detection in Difference Images Open
Trans-Neptunian objects provide a window into the history of the solar system, but they can be challenging to observe due to their distance from the Sun and relatively low brightness. Here we report the detection of 75 moving objects that …

A Gateway to Astronomical Image Processing: Vera C. RubinObservatory LSST Science Pipelines on AWS Open
The Legacy Survey of Space and Time, operated by the Vera C. Rubin Observatory, is a 10-year astronomical survey due to start operations in 2022 that will image half the sky every three nights. LSST will produce ~20TB of raw data per night…

Sustaining Community-Driven Software for Astronomy in the 2020s Open
Software is critical to astronomical research. Sharing and sustaining astronomical software has long-term impacts on scientific outcomes. However, support for this has been uneven, creating significant risks. Thus, we highlight changes tha…

Fast Algorithms for Slow Moving Asteroids: Constraints on the Distribution of Kuiper Belt Objects Open
We introduce a new computational technique for searching for faint moving sources in astronomical images. Starting from a maximum-likelihood estimate for the probability of the detection of a source within a series of images, we develop a …

Linear feature detection algorithm for astronomical surveys – II. Defocusing effects on meteor tracks Open
Given the current limited knowledge of meteor plasma micro-physics and its\ninteraction with the surrounding atmosphere and ionosphere, meteors are a\nhighly interesting observational target for high-resolution wide-field\nastronomical sur…
