dc.description.abstract | A photometric study of galaxy disk images is carried out in this final degree project , creating their
observed surface brightess, Sloan Digital Sky Survey (SDSS) restframe surface brightness and mass profiles.
The main goal of our study is the detection of some features in the flux/brightness profile for a selection
of galaxies that can lead into the so-called Truncations or galactic ”boundaries”. The galaxies images were
obtained from the most modern galaxy surveys like Great Observatories Origins Deep Survey or Sloan Digital
Sky Survey .
I also present the theoretical context to motivate the physical background for this project. Several concepts
such as Redshift, Black-Body radiation and Magnitude system take a big part in this project. Furthermore, a
computational method is presented, consisting on an elliptical brightness integration of flux. Other methods
can also be applied consisting in a radial integration [1].
It is to note that, to achieve the aims of this work, I had to modify or write a number of computer
programs in Python, as well as reading specific literature in Astrophysics. Finally, as a proof of concept, an
analysis of 3 different galaxies is performed, 2 of them being classified as “Relic Galaxies”. | es |
