Abstract We present the first set of trans-Neptunian objects (TNOs) observed on multiple nights in data taken from DECam Ecliptic Exploration Project. Of these 110 TNOs, 105 do not coincide with previously known TNOs and appear to be new discoveries. Each individual detection for our resulted a digital tracking search at TNO rates motion, using two-to-four-hour exposure sets, detections were subsequently linked across observing seasons. This procedure allows us find magnitudes m VR ≈ 26. The...
Computer vision algorithms are powerful tools in astronomical image analyses, especially when automation of object detection and extraction is required. Modern astronomy oriented towards stars galaxies, ignoring completely the existing linear features. With emergence wide-field sky surveys, features attract scientific interest as possible trails fast flybys near-Earth asteroids meteors. In this work, we describe a new feature algorithm designed specifically for implementation big data...
Given the current limited knowledge of meteor plasma micro-physics and its interaction with surrounding atmosphere ionosphere, meteors are a highly interesting observational target for high-resolution wide-field astronomical surveys. Such surveys capable resolving physical size heads, but they produce large volumes images that need to be automatically inspected possible existence long linear features produced by meteors. Here we show how big aperture sky survey telescopes detect as defocused...
Trans-Neptunian Objects (TNOs) provide a window into the history of Solar System, but they can be challenging to observe due their distance from Sun and relatively low brightness. Here we report detection 75 moving objects that could not link any other known objects, faintest which has VR magnitude $25.02 \pm 0.93$ using KBMOD platform. We recover an additional 24 sources with previously-known orbits. place constraints on barycentric distance, inclination, longitude ascending node these...
We present "Tracklet-less Heliocentric Orbit Recovery" (THOR), an algorithm for linking of observations Solar System objects across multiple epochs that does not require intra-night tracklets or a predefined cadence within search window. By sparsely covering regions interest in the phase space with "test orbits", transforming nearby over few nights into co-rotating frame test orbit at each epoch, and then performing generalized Hough transform on transformed detections followed by...
We introduce a new computational technique for searching faint moving sources in astronomical images. Starting from maximum likelihood estimate the probability of detection source within series images, we develop massively parallel algorithm through candidate asteroid trajectories that utilizes Graphics Processing Units (GPU). This can search over 10^10 possible stacks order 10-15 4K x images under minute using single consumer grade GPU. apply this to data 2015 campaign High Cadence...
A foundational goal of the Large Synoptic Survey Telescope (LSST) is to map Solar System small body populations that provide key windows into understanding its formation and evolution. This especially true Outer -- objects at orbit Neptune $r > 30$AU beyond. In this whitepaper, we propose a minimal change LSST cadence can greatly enhance LSST's ability discover faint distant across entire wide-fast-deep (WFD) survey area. Specifically, WFD be constrained so as deliver least one sequence...
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 sky every three nights. LSST produce ~20TB raw data per night which be calibrated analyzed almost real time. Given volume data, traditional subset-download-process paradigm reprocessing faces significant challenges. We describe here, first steps towards gateway for science would enable astronomers analyze images catalogs at...
