Classification and modeling of time series of astronomical data
(2018)
We are living in the era of Big Data, where several tools have been developed to deal with large amount of data. These technological advances have allowed the rise of the astronomical surveys. These surveys are capable to ...
The radial velocity profiles of some proplyds in the Orion Nebula
(2003)
We use H? scanning Fabry-Perot interferometric data on the Orion Nebula in order to study the proplyds of the central region. We find that Fabry-Perot interferometry constitutes an effective technique for the detection and ...
Positional encodings for light curve transformers: an evaluation of their impact in the pretraining and classification task.
(Universidad de Concepción, 2024)
The vast volume of astronomical data generated nightly by observatories, such as the Vera C. Rubin Observatory, presents significant challenges in the classification and analysis of light curves. These curves, characterized ...
A global data warehouse for astronomy
(2018)
There have been many attempts to gather and integrate numerous astronomical data
sources to create a centralized, organized and consolidated database with visualization and
analysis add-on tools. Unfortunately, most of ...
Hierarchical Storage Management System For Big Data Astronomical Research.
(2017)
We proposed to purchase and install a new hierarchical storage system to be used by the Astroinformatics Laboratory (AstroLab) at the Center for Mathematical Modeling (CMM) of the University of Chile (UChile). The AstroLab ...
Scalable end-to-end recurrent neural network for variable star classification
(OUP, 2020)
During the last decade, considerable effort has been made to perform automatic classification of variable stars using machine-learning techniques. Traditionally, light curves are represented as a vector of descriptors or ...
