MÓDULO_ 01 Astronomía y Física 32 TRANS-NEPTUNIAN OBJECTS DETECTION FROM GROUND-BASED TELESCOPES: A FAST AND EFFICIENT APPROACH USING DEEP LEARNING CNN WITH THE DEEP ECLIPTIC EXPLORATION PROJECT (DEEP) ABSTRACT The trans-Neptunian region offers a unique opportunity to study the same planetesimals from which the planets in our solar system formed. The Deep Ecliptic Exploration Project (DEEP), a multiyear survey program investigated the trans-Neptunian region, characterizing the size and shape distribution of faint TNOs, investigate their physical properties in relation to dynamical class and size, while following the candidate TNOs over two or more years. The project employs the Dark Energy Camera (DECam) on the 4-meter Cerro Tololo Inter- American Observatory (CTIO) Blanco telescope, identifying and characterizing the orbits of thousands of Trans-Neptunian Objects (TNOs). The DEEP search for TNOs was performed using a shift-and- stack moving object detection algorithm and recovered 110 new objects. However, we used a different method, offering a fresh perspective on the detection and characterization of TNOs. Here we present an AI-based moving object detection technique. Instead of following the traditional shift and stack method, we perform simple stacking on single field night images using different statistics, which later are seached for TNOs trails with the help of AI. The primary objective of the project is to develop an optimized algorithm for expedited analysis of large datasets, enabling the detection of faint TNOs using the DEEP results as benchmark magnitude limit of R ̴26.2. Notably, the algorithm’s strength lies in its ability to quickly process large volumes of data while minimizing false positives, and also enabling real-time detection of moving objects as soon as the data becomes available. In this presentation, I will delve into the key methods used in this innovative technique and discuss some of the challenges faced during its development. Also, I will discuss how this can be implemented in deep drilling fields from LSST, and other wide field surveys, possibly enhancing the yield of new Solar System Objects, particularly for those that exhibit a sky motion unsuitable for deep drilling.
