About Me

Turgay CAGLAR

High Energy Astrophysics

Hello, I am a young passionate researcher, and I study large-scale structures of the universe. My main interest is clusters of galaxies, particularly, ICM dynamics, merging process and evolution of clusters of galaxies. In addition, I study X-ray sources from clusters of galaxies, in particular, galaxy evolution in clusters of galaxies, AGNs and XRBs. I am mostly working with X-ray data from XMM-Newton and Chandra, I also work with Suzaku, ASCA and NuStar X-ray data.

Here you may find my recent research topics and publications. Also this page provides my Curriculum Vitae.









Research Interests






Environmental Dependencies


Clusters of galaxies are the largest structural entities of the universe, and they are formed from gravitational collapses. The purpose of this study is to understand the influence of the environment on the evolution of galaxies. There is an open question whether clustering process suppress or trigger X-ray emission from member galaxies. Therefore, I study nearby galaxy clusters to solve this conflict.

Cluster Mergers

Cosmological models predict that small structures are formed firstly, then, large-scale structures of the universe are formed by merging with other structures. Comparisons of optic and X-ray data of galaxy clusters have been very successful to explain dynamics of merging process so far. Big events like cluster mergers increase the kinetic energy of plasma into thermal energy. Therefore, I concentrate on understanding one of the heating mechanism of the universe, namely galaxy cluster mergers.
