Statement of purpose, please help me

When I was a child, I used to watch the Moon with a sense of amazement and admiration. I wondered what it was, what material it was made of, why it was shining and why such a particular object was visible in the night sky.

Becoming older, it was not enough to know that the Moon is a satellite of the Earth and that it is visible because it reflects the light of the Sun. I wanted to understand and know the way the Moon orbits around the Earth and it was not enough to know that the reason is gravity. For a young boy ot was incredible understanding how it was possible that a huge mass could rotate around our planet, and how the Earth could rotate around the Sun and, again, how the sun could be a star of our galaxy.

During the high school years, my questions did not stop at the Moon and I kept wondering how the world and nature worked.

I found the physics lessons very exciting, to the point that, over time, I decided to enroll in the physics faculty of the University of xxx, where I graduated in 2014. After physics, I decided to do the master degree in astrophysics and cosmology for my admiration in subjects like black holes and the evolution of the universe.

In the last few years I have understood where I wanted to work and make a career, that is in the field of Active Galactic Nuclei (AGN), particularly in the high energies bands, but with an interest in the whole electromagnetic spectrum.

During my academic career I have chosen to expand my knowledge and experiences through specific courses and laboratories, in order to ensure a wide basis of physical phenomena and theory, and also to go into depth on the matter of some specific subjects, such as modern astrophysical topics and practical ways to practice science in a professional environment.

I therefore decided to start a project under the supervision of professor xxx and co-supervison of doctor xxx and doctor xxx on the study of AGN obscured in the deep field of xxxx, a quasar at redshift 4.5. In this thesis I have dealt with the characterization of these objects starting from the X-ray spectral analysis, assisted with spectral simulations and with a study of optical and infrared photometry. I graduated last September with honours.

My thesis work allowed me to become interested in the study of AGN, a subject in which I would like to make my way and have a profitable career.

In December I won a scholarship at xxx, where I am currently working and where, under the supervision of xxx, I continue to deal with obscured AGN in the deep field of xxx and I also have started the development of an algorithm for the identification of optical, infrared and radio counterparts of the sources detected in the X-ray band within this field.

In the last 20 years, X-ray astronomy has given an enormous support to the understanding of AGN and how sumermassive black holes behave when they interact with the surrounding matter. The observations of these objects with modern telescopes and the use of simulations will, in the future, allow a better understanding of supermassive black holes (both as they were born and evolved, and how they behave in general) and I would like to be part of this.

Thanks to professor xxx I learned about the physics PhD at the University of xxx and about possibile projects that include obscured AGN, cosmic X-ray background and high redshift source identification. These projects are just what I would like to study in the future to further my career in these fields and I think xxx is a great place to do this. I know that Miami is a modern and multicultural city, where people from all over the world live and work together in an environment that becomes very stimulating and in which I would like to be part of.

In addition it is since childhood that I dream of being able to work in the United States, that is one of the places from where the first missions for the Moon started, which I have loved so much since I was a child.
