astromorphlib 1.0.14

Python scripts to analyze the morphology of isolated/interacting galaxies

Overview

Python scripts to analyze the morphology of isolated and interacting galaxies.

The package is designed to automatically download imaging data from:

• S-PLUS (https://splus.cloud/)
• Legacy Survey (https://www.legacysurvey.org)
• SDSS DR17 Imaging (https://www.sdss4.org/dr17/imaging)

The library also includes functionality to perform photometric modeling using simulated galaxy images, allowing controlled experiments and validation of morphological measurements.

There are functions to:

• Calculate a 2D sky background of the images
• Generate deblended segmentation maps of interacting systems with merger isophotes
• Perform non-parametric morphological analysis using the statmorph package.

Users can also study the environment of an object/system by downloading a list of galaxies within the Field-of-View of S-PLUS/Legacy images from the SIMBAD server (http://simbad.u-strasbg.fr/simbad/).

In addition, the package includes a function to display DSS2 images (http://alasky.u-strasbg.fr/hips-image-services/hips2fits) of any size.
