SCORPIO, a package for the visualization of galaxy pairs
Jose A. Benavides, Martín Chalela, Juan B. Cabral +2
We present the description of the project \texttt{SCORPIO}, a Python package for retrieving images and associated data of galaxy pairs based on their position, facilitating visual…
Being nice to the server: Wrapping a REST API for a cosmological distance/velocity calculator with Python
Juan Cabral, Ehsan Kourkchi, Martin Beroiz +2
In this paper we present PyCF3, a python client for the cosmological distance-velocity calculator CosmicFlow-3. The project has a cache and retry system designed with the objective…
Drifting Features: Detection and evaluation in the context of automatic RRLs identification in VVV
J. B. Cabral, M. Lares, S. Gurovich +2
As most of the modern astronomical sky surveys produce data faster than humans can analyze it, Machine Learning (ML) has become a central tool in Astronomy. Modern ML methods can b…
GriSPy: A Python package for Fixed-Radius Nearest Neighbors Search
Martin Chalela, Emanuel Sillero, Luis Pereyra +4
We present a new regular grid search algorithm for quick fixed-radius nearest-neighbor lookup developed in Python. This module indexes a set of k-dimensional points in a regular gr…
Astroalign: A Python module for astronomical image registration
Martin Beroiz, Juan B. Cabral, Bruno Sanchez
We present an algorithm implemented in the astroalign Python module for image registration in astronomy. Our module does not rely on WCS information and instead matches 3-point ast…
Machine Learning on Difference Image Analysis: A comparison of methods for transient detection
B. Sánchez, M. J. Domínguez R., M. Lares +12
We present a comparison of several Difference Image Analysis (DIA) techniques, in combination with Machine Learning (ML) algorithms, applied to the identification of optical transi…
