2016 Severo Ochoa PhD Students




Carlos Cardona Guillén Stellar and Interstellar Physics
I started my education in Zaragoza, where I took a Physics Degree. After realizing that astrophysics was what I really liked, I moved to Universidad de La Laguna where I got my Master in Astrophysics, which in turn allowed me to start my PhD in the IAC under the supervision of Dr. Víctor Sánchez Bejar and Dr. Nicolas Lodieu. The aim of this thesis is to study the existence of exoplanets in young star clusters. However, these young late-type stars usually present activity signs that hinder the detection of such exoplanets, so an additional goal for the thesis will be to attempt to characterize and filter these signals.

 

 

Nuria Salvador Rusiñol Formation and Evolution of Galaxies

I'm doing my PhD thesis under the supervision of Alexandre Vazdekis and Michael A. Beasley. The main goal of the project is to explore the UV spectral range to constrain the evolution of massive early-type galaxies. These galaxies are considered to be the end-product within a hierarchical galaxy formation framework. The UV range provides a unique capability for disentangling tiny contributions from young stellar components that almost do not shine in the visible. Observations of UV spectra, absorption line-strength indices and colors from statistical meaningful studies as well as very detailed studies of cluster galaxies at varying redshift will be compared with newly extended stellar population models that cover a wide range of ages, metallicities and initial mass functions. The results of my work will be of great value to current galaxy formation and cosmological numerical simulations.

 

 

Jaume Jaume Bestard Solar Physics

My PhD project is supervised by Dr. Javier Trujillo Bueno (IAC) and Dr. Jiri Stepan (ASCR). The aim of the project is to study the magnetic field of the solar atmosphere comparing spectropolarimetric observations with novel 3D simulations of radiative transfer. With a fair knowledge of how the Zeeman and Hanle effect and optical pumping polarize the radiation, it is possible to infer in the structure of the magnetic field in the solar atmosphere improving our knowledge of the solar chromosphere.

 

 

Alejandro Reina Conde Cosmology and Astroparticles

I obtained a Physics Degree by the University of La Laguna, where I did the astrophysics branch. Later I did the Master of Astrophysics in the same university and in collaboration with the IAC. My final work was supervised by Alberto Rubiño and Ignacio Trujillo, the main point of the work was to study the possibility that some galaxy clusters can have less gas that expected according its mass, using the newest surveys supplied by the spacecraft PLANCK. Actually I am doing my PHD in the project AMS (Alpha Magnetic Spectrometer), under the supervision of Ramon Lopez and Alberto Oliva. This project is dedicated to study the chemical composition of the cosmic rays.

 

 

 Paula Izquierdo Sánchez Exoplanets and Solar System

My PhD is supervised by Pablo Rodriguez Gil (IAC) and Boris Gäensicke (University of Warwick). The aim of this project is to increase the number of planetary remnant systems known to date and to obtain and analyze follow-up observations making use of the Hubble Space Telescope (HST), the Very Large Telescope (VLT) and the Gran Telescopio de Canarias (GTC). The great majority of all planet-hosting stars will finally evolve into white dwarfs (WDs) and the close-in planets will evaporate. However, asteroids and planets beyond a few astronomical units will survive this phase and they can be detected in the form of circumstellar debris transiting the WD. By studying these systems we are able to learn about the chemistry in extrasolar planets which is currently unachievable in other way, as well as to derive some important characteristics of the system, such as the superficial gravity or the luminosity.

 

 

Javier de Miguel Hernández Instrumentation

My PhD thesis, supervised by Dr. Roger Hoyland, is focused on the research and development of innovative instruments dedicated to the study of the Cosmic Microwave Background (CMB). The CMB is the main tool for the study of the earliest epochs of the Universe, and the instruments that we are developing here could help us to explore the Age of Reionization, to restrict the Inflation to scales below 1Mpc, to study the relics of the decay and annihilation, the metals during dark ages or the cosmological radiation of recombination, among others. My work also explores the applications that the prototypes that I am developing for my thesis could offer in the field of the medical technology.
