Galmoss: A package for GPU-accelerated galaxy profile fitting
Chen, Mi; Souza, Rafael S. de; Xu, Quanfeng; Shen, Shiyin; Chies-Santos, Ana L.; Ye, Renhao; Canossa-Gosteinski, Marco A.; Cong, Yanping (2024-04-22)We introduce galmoss, a python-based, torch-powered tool for two-dimensional fitting of galaxy profiles. By seamlessly enabling GPU parallelization, galmoss meets the high computational demands of large-scale galaxy surveys, ... -
NSCs from groups to clusters: A catalogue of dwarf galaxies in the Shapley Supercluster and the role of environment in galaxy nucleation
Zanatta, Emilio J. B.; Sanchéz-Janssen, Ruben; Souza, Rafael S. de; Chies-Santos, Ana L.; Blakeslee, John P. (2024-05-01)Nuclear star clusters (NSCs) are dense star clusters located at the centre of galaxies spanning a wide range of masses and morphologies. Analysing NSC occupation statistics in different environments provides an invaluable ... -
Spatially resolved self-consistent spectral modelling of jellyfish galaxies from MUSE with FADO: trends with mass and stripping intensity
Azevedo, Gabriel M.; Chies-Santos, Ana L.; Riffel, Rogério; Gomes, Jean M.; Lassen, Augusto E.; Benedetti, João P.~V.; de Souza, Rafael S.; Xu, Quanfeng (2023-08-30)We present a spatially resolved stellar population analysis of 61 jellyfish galaxies and 47 control galaxies observed with ESO/MUSE attempting to understand the general trends of the stellar populations as a function of ...
