Proposals for Supervising Licencjat and Masters (Magister) projects at TCfA

Nov 2005 - Sep 2006

Projekt licencjat jest w sensie naukowy podobny do projekt magisterski, tylko jest mniej ambitny, np w sensie zrobiony własne kalkulacji. Jednak jest równie ważny że student myśli dla siebie i skeptycznie próbuje rozumieć temat.

A podobnie, badania na poziom doktoratu, może być na podobnych tematów do projektów licencjatu/magisterski, ale oczywiście, może być więcej głęboki a jest więcej szans, że będzie na poziom wystarczający dla publikowanie w czasopismie.

Były i aktualne studenci kosmologii w TCfA:

• doktorat - integrowany na CosmoProjects
• StudMagister
• StudLicencjat

Supervisor: B. Roukema (boud at astro.uni.torun.pl)

Number of students: up to 3-4 students is possible

Observational Cosmology Masters/Licencjat Project - General Outline

Description:

There are many possible projects which could be done as a master's thesis project, in using publicly available archival data from observational surveys to constrain one or more of the local or global cosmological parameters, either those related to shape (curvature, topology) or maybe also those unrelated to shape ("dark energy" or "dark matter"). The precise projects would be chosen in discussion with the masters/licencjat students. Please see http://cosmo.torun.pl/cgi-bin/twiki/view/Cosmo/CosmoProjects for projects that the cosmology group is working on and http://cosmo.torun.pl/cgi-bin/twiki/view/Cosmo/CosmoNews for ideas on the hottest topics in cosmology research - any of these would be appropriate if the student is sufficiently interested. Some examples are on http://cosmo.torun.pl/cgi-bin/twiki/view/Cosmo/LicMagTematy.

Reproducible galaxy formation pipeline

rodzaj praca: mag/lic, specjalność: astronomia/fizyka matematyczna

In ArXiv:2010.03742 a reproducible galaxy formation pipeline is established. The initial results showed that void location contributes to a later epoch of a dark matter halo's initial collapse, which tends to imply a lower density at the collapse epoch of the halo, and a higher dimensionless spin parameter of the disk that forms in the halo, tending to imply a lower surface density of matter in the disk. Both effects imply that void location contributes to low surface brightness galaxy (LSBG) formation. Several extensions to develop these initial results further would be possible as straightforward and potentially publishable undergraduate research projects. A side benefit of the project would be an introduction to a state-of-the-art method of making a scientific computational project reproducible by independent scientists.

Non-perturbative N-body/GR simulations

rodzaj praca: mag/lic, specjalność: astronomia/fizyka matematyczna

N-body simulations (e.g. AstroPh:0411043, ArXiv:1105.1082, AstroPh:0111367) used for the modelling of 0.1 to 5 Gpc scale structure formation assume a rigid Friedmann-Lemaitre-Robertson-Walker (FLRW) background against which perturbations grow according to Newtonian gravity, while the FLRW background itself evolves assuming that structure formation do not form. An UMK-Lyon project is underway to develop relativistic methods of correcting N-body simulations for this contradiction, by using scalar averaging (AstroPh:9912347, ArXiv:0707.2153, ArXiv:0803.1401, ArXiv:1203.6263, ArXiv:1303.6193). The main result of the full project (ArXiv:1706.06179) is that more accurate simulations help show that "dark energy" is a misinterpretation of the virialisation epoch, during which much of the most massive galaxies and galaxy clusters formed. The student's contribution would be in checking caveats of this calculational method and/or proposing extensions. Other codes including Einstein Toolkit/FLRWSolver or Gevolution could alternatively be considered for the project.
