    Sažetak

    I will discuss some aspects of the research related to my  
short-term research stay at the University of Oldenburg. We will  
mainly touch upon the general basics, beginning with the theory of  
General Relativity (GR) and the recently observed astrophysical events  
that verified the predictions of the theory, with one of the  
accomplishments being the detection of a binary neutron star merger.  
The gravitational waves during the ringdown phase are emitted at  
characteristic frequencies that can be calculated using the  
quasinormal modes. In spite of the success of GR so far, there have  
been proposals of modified gravity theories which attempt to overcome  
the shortcomings of GR in view of the dark energy for instance. We  
will see how the analysis in an alternative gravity theory known as  
R^2 gravity works in the quasinormal mode formalism.
