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…
Arby Fast data-driven surrogates
Aarón Villanueva, Martin Beroiz, Juan Cabral +2
The availability of fast to evaluate and reliable predictive models is highly relevant in multi-query scenarios where evaluating some quantities in real, or near-real-time becomes…
On the weak lensing masses of a new sample of galaxy groups
Elizabeth J. Gonzalez, Facundo Rodriguez, Manuel Merchán +6
Galaxy group masses are important to relate these systems with the dark matter halo hosts. However, deriving accurate mass estimates is particularly challenging for low-mass galaxy…
Easy asteroid phase curve fitting for the Python ecosystem: Pyedra
Milagros Colazo, Juan Cabral, Martin Chalela +1
A trending astronomical phenomenon to study is the variation in brightness of asteroids, caused by its rotation on its own axis, non-spherical shapes, changes of albedo along its s…
Measuring the surface mass density ellipticity of redMaPPer galaxy clusters using weak-lensing
Elizabeth J. Gonzalez, Martin Makler, Diego Garcia Lambas +5
In this work we study the shape of the projected surface mass density distribution of galaxy clusters using weak-lensing stacking techniques. In particular, we constrain the averag…
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…
