Hakkımızda

eGRAVITY (Ege Gravitational Astrophysics Group: theory, observation and computational) is a team of researchers, based at the University of Ege, İzmir, Turkey. Our research group was established in 2010. We are working on gravitational astrophysics in the context of stellar evolution, black holes, gravitational waves, and numerical relativity. 


Gravitational Waves:

The direct observation of gravitational waves with new generation instruments (LIGO, Virgo, LISA) opens new opportunities for the study of neutron stars, black holes, and other relativistic binary stars.




Black Holes Physics:

Black holes deform the space-time around them. They are possibly the most fascinating objects in the Universe. Black holes are highly dense spherical conglomerates of rotating matter, exhibiting strong gravitational effects. In 2015 LIGO team succeeded at detecting gravitational waves from colliding black holes.



Structure and Evolution of Binary Systems:

A binary star system is a gravitationally bound two components that orbit around their center of mass. Most stars in the sky are in binary or even triples and quadruplets. They are very important objects in Astronomy and Astrophysics. Photometric and spectroscopic observations of binary and multiple systems allow one to determine accurate physical and orbital parameters of component stars. We can test stellar formation, structure, and evolution using binary parameters.




Astrophysics and Numerical Relativity:

In Einstein's theory of General Relativity (GR), gravity is governed by an extremely complex set of nonlinear differential equations. Research in Numerical Relativity (NR) is involved in the modeling and simulation of binary black holes and binary neutron stars. NR uses some numerical techniques in computers to simulate the relativistic effect of colliding binary compact systems.
