The scientific experiment represented by this research object pertains to the multi-wavelength study for a sample of the most isolated galaxies in the local universe. This study characterizes each galaxy of this sample through both the measurement of basic astrophysical properties: - The equatorial coordinates in J2000 epoch - The velocities in km/s (v) - The dust extinction coefficient (ag) - The axis ratio of the isophote 25 mag/arcsec2 (logr25) - The apparent total B magnitude (BT) ...

In order to understand the evolution of galaxies, detailed analysis of images plays a key role. During the last years telescopes working at different wavelengths have been imaging the whole sky. One example of this is the Sloan Digital Sky Survey. The generated images provides a wealth of information, publicly available, and hence allowing them to be used by any interested group in the study of their own samples of objects or generation of new samples. The two main processing of the images ge...

Workflow Comparison and update values (1)

Thumb
This workflow receives two files, the name of a table and the name of a field as input. One of the file should be contain a list of old values (name galaxy and value), and the other one should be a list of new values (name galaxy,value) The workflow makes a comparison between the two files. This comparison will be a list of 7 columns: name of the galaxy, old value, old error, new value, new error, difference of value, difference of error. In other hand, this workflow makes a sql script with ...

Workflow Gathering galaxy properties using HyperLEDA (2)

Thumb
The user provides an ASCII text file with a list of galaxy names, and the workflow queries the HyperLEDA database and parses the response with the help of regular expressions included in simple Python scripts. The result of the workflow is a series of ASCII text files with the values of the equatorial coordinates in J2000 epoch, the velocities in km/s, the dust extinction coefficient Ag, the axis ratio of the isophote 25 mag/arcsec2 logr25 and the apparent total B magnitude BT. The performanc...

Thumb
This workflow takes as input a file for each of this properties: J2000 Coordinates, velocity, galactic extinction, log of axis ratio, and the Total B-magnitude. With this properties it calculates the distance of the galaxy and, in other hand, the total apparent corrected B-magnitude. It takes account if the velocity of the galaxy is lower than a threshold (1000km/s), it can not be possible to calculate the distance so, in those cases the distance will be "NaN". At the end, it calculates the ...

Workflow VOTable of NED Images from a List of Objects (1)

Thumb
Extraction of metadata using NED Image Virtual Observatory Service into a single VOTable, providing a list of objects and the width for each field in arcmin. Among the most relevant metadata are the URL link to the FITS images. This Wf makes use of a Tool developed as an internal pyhton script file.

Workflow Intialize Sample (2)

Thumb
This workflow saves a tabular *.pckl Python pickle dataset in the local file system, containing values calculated on physical parameters associated to potential companions of a sample of target galaxies. These original physical parameters are extracted from a postgreSQL database, containing information of all galaxies covered by the SDSS spectroscopic survey. The workflow first access the external database located in the AMIGA server and selects the target galaxies from the sample (those havi...

Workflow Environment (2)

Thumb
From a previously selected cube of galaxies residing in a remote database, we provide extragalactic environment parameters for all galaxies sample. This workflow takes as input the path of the tabular *.pckl Python pickle dataset created in the previous workflow, as well as the database connection settings and several criteria on how to filter the potential companions of the target galaxies. It provides a file with the SDSS identifiers of each target galaxy of the sample, environmental estim...

Thumb
From an initial list of galaxy names, retrieve some of their properties from Virtual Observatory archives and services (NASA Extragalactic Database NED), and calculate others like Distance, based on the ones previously obtained (e.g. recession velocity, equatorial and galactic coordinates). The sample is filtered in a later step with criteria related to the angular size of the object and its declination. The goal is to build a sample of objects and their properties with up-to-date physical in...
