Project 1: Testing the presence of quark matter inside neutron stars
Quantum chromodynamics predicts that at sufficiently high densities, nuclear matter will undergo a phase transition to quark matter. This prediction can be tested by combining available theoretical knowledge, experimental data and astrophysical observations of neutron stars (NSs). In this project we will use piecewise polytope parameterization to describe the hadronic matter and above the hadron-quark transition density constant speed of sound quark matter equation of state (EOS) will be used. The student has to write a numerical code to develop this generic equation of state parameterization (of course he/she will be helped). Once it is developed lots of exciting problems can be done:
- Calculate mass-radius sequence and tidal Love number of NSs
- Develop robust statistical framework to test the presence of quark matter inside the core of NSs.
Project 2: Investigating tidal interactions in the Galactic Centre
The centre of the Milky Way is among the most intriguing regions in the Galaxy. The presence of the super-massive black hole Sgr A*, the nuclear star cluster and the extremely hot plasma filling the region making it an ideal laboratory for studying physics in an extreme environment. In the last decade, many gaseous and dusty sources have been detected whose nature still remain unknown. Specifically, it is not clear if such sources are purely gaseous or if they have a star embedded in them. This project aims to constrain the age and place of origin of one of such objects that seems to be interacting tidally due to the gravitational pull of Sgr A*. To do so, the student will conduct a series of Newtonian calculations, test-particle and/or hydrodynamic simulations. The resulting models will be contrasted with real observational data of the object to asses their validity. Properties such as mass, size, shape, and medium properties will be investigated in order to characterise a potential formation region and time for the enigmatic source. Further continuation of the project can result into a scientific publication as a part of an international collaboration.
