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…
