Already during my diploma thesis on nonlinear oscillations of neutron stars I have been fascinating by neutron stars. Fortunately, I could follow my interested by doing my thesis on magneto-elastic oscillations of magnetars, which are a particular class of highly magnetized neutron stars. After my first PostDoc, working on these kind of oscillations and emission processes of magnetars, I started to broaden my interest further and joined the Garching supernova group and worked on long-time evolutions of supernova. Before finally arriving at my current possition in Valencia as a distinguished researcher, where I develop a reasearch program on long-time supernova simulations, I was working as an visiting professor in Ilhéus. There, I discovered my interest in teaching the new generation of physics students.
Research Experience
Senior PhD Researcher
PI of the project: 3D-Loss:
The main goal is to connect supernova explosions to their remnants. With 3D long-time simulations we would like to answer questions like: Do different classes of progenitors lead to different observables in the lightcurves, spectra or the distribution of elements in supernova remnants?
What can we learn from the observations of particular nearby supernova remnants like SN 1987A, Cas A or Crab nebula? How can we connect the results of our simulations to observations (quantitavely)?
Visiting Professor
Teaching of various theoretical and laboratory curses in the bachelors degrees of physcics, biology, computer science, and engineering. Paricipation in the supervision and examination of theses.
Senior PhD Researcher
PostDoc researcher involved in the ERC AdG No.341157-COCO2CASA led by Prof. H.-T. Janka. During this project, I extended the 3D hydrodynamical code PROMETHEUS-HOTB to be employable to perform long-time simulations of supernova explosions, which were used to couple the gap between 3D explosion engine simulations and the late supernova remnant stage.
Junior PhD Researcher
Investigation of the effects of superfluid phases in the core of magnetars on their magneto-elastic oscillations. Study of how the (internal) mag and magnetar spectra.neto-elastic oscillations can influence and couple to the external magnetic field. Development of a numerical model to calculate the spectra of magnetar. This tool is also used to describe the modulation of the emission due to the coupling of the magneto-elastic oscillations of the magnetar to its magnetospheric field.
PHD Thesis
Max-Planck-Institute for Astrophysics, Garching, Germany
In this thesis we describe a model which can explain the quasi-periodic oscillations observed in gamma-ray flares of soft gamma-ray repeaters. These oscillations are assumed to originate from the magneto-elastic pulsations of a highly magnetized neutron star. These modulate the magnetic field in the exterior of the star and thus create electric currents in the magnetosphere. Photons emitted from the stellar surface or by the flare can scatter resonantly (cyclotron scattering) off the charge carriers, which are mostly electrons and positrons. Thereby, the intensity of the radiation changes in certain frequency bands and the observed light curve is modulated. In analogy to seismology for the earth or for the sun, it is possible to learn about the interior magnetic field of the neutron star and about its interior structure.
Diploma Thesis
Friedrich-Schiller-Universität Jena, Germany
In order to study nonlinear oscillations in full nonlinear general relativity, highly accurate numerical studies are required. We developed a numerical scheme specifically tailored for such a study based on formulating the time evolution in terms of deviations from a stationary equilibrium configuration. Using this technique, we investigate nonlinear effects in the evolution of radial oscillations of neutron stars. In particular, we discuss mode coupling due to nonlinear interaction, the occurrence of resonance phenomena, formation of discontinuities near the stellar surface as well as the capacity of nonlinearities to stabilize perturbatively unstable neutron star models.
