Querying an astronomical database using large language models: the ALeRCE text-to-SQL system

P. A. Estevez, J. Espejo-Moreira, S. Sanfeliu-Alvarez +10

We develop a text-to-SQL (structured query language) system based on large language models (LLMs) using in-context learning and apply it to the Automatic Learning for the Rapid Cla…

Temporal Stamp Classifier: Classifying Short Sequences of Astronomical Alerts

Daniel Neira O., Pablo A. Estévez, Francisco Förster

In this work, we propose a deep learning-based classification model of astronomical objects using alerts reported by the Zwicky Transient Facility (ZTF) survey. The model takes as…

Improving Astronomical Time-series Classification via Data Augmentation with Generative Adversarial Networks

Germán García-Jara, Pavlos Protopapas, Pablo A. Estévez

Due to the latest advances in technology, telescopes with significant sky coverage will produce millions of astronomical alerts per night that must be classified both rapidly and a…

Alert Classification for the ALeRCE Broker System: The Real-time Stamp Classifier

Rodrigo Carrasco-Davis, Esteban Reyes, Camilo Valenzuela +20

We present a real-time stamp classifier of astronomical events for the ALeRCE (Automatic Learning for the Rapid Classification of Events) broker. The classifier is based on a convo…

Asteroids in the High cadence Transient Survey

J. Peña, C. Fuentes, F. Förster +11

We report on the serendipitous observations of Solar System objects imaged during the High cadence Transient Survey (HiTS) 2014 observation campaign. Data from this high cadence, w…

The High Cadence Transient Survey (HiTS) - I. Survey design and supernova shock breakout constraints

Francisco Förster, Juan C. Maureira, Jaime San Martín +19

We present the first results of the High cadence Transient Survey (HiTS), a survey whose objective is to detect and follow up optical transients with characteristic timescales from…
