Llegando a los límites del bajo brillo superficial en la imagen de IC1101

Abstract

Since the invention of the telescope in 1608, numerous technological breakthroughs have allowed us to improve the quality of the technology around us, while at the same time increasing our understanding of the Universe and our curiosity. In this End of Degree Assignment, I will try to take advantage of the latest technological advances in astronomy to study the largest galaxy ever found, IC1101. The theoretical background related with Extragalactic Astrophysics will be presented introducing concepts such us magnitude, black body, CCD, redshift, etc. In addition, the computational background utilized during this work will also be explained. I carried out a photometric study of IC1101 determining its surface brightness profile and mass profiles among other observables. Furthermore, I will also show how the IC1101 image was taken, and I will compute the external part of the PSF of its images. This analysis will help us obtaining information about the mysterious IC1101 galaxy. It should be emphasized that, in order to accomplish the present work, I had to develop several programs in Python as well as read and understand many Astrophysical concepts which helped me to obtain a first insight on what research really is.
