Abdurrahman Savaş Arapoğlu

Abdurrahman Savaş Arapoğlu is a Professor at the Department of Physics Engineering, Istanbul Technical University. His research focuses on cosmology, general relativity, scalar field theories, and neutron star physics. He is actively involved in projects investigating cosmological phase transitions and gravitational wave dynamics.

He has led TÜBİTAK-funded projects on cosmological phase transitions and gravitational waves (2021-2024) and currently directs a BAP project on O(D,D)-symmetric cosmological dynamics (2024-2025). His work bridges theoretical frameworks with observational cosmology, contributing to our understanding of dark energy and modified gravity.

Key research areas include:

• Scalar-tensor theories and their cosmological implications
• Phase transitions in anisotropic universes
• Gravitational wave signatures from early universe processes

His recent publications (2020-2024) address topics like neutron star mass-radius relations, stability analysis in stringy gravity, and numerical solutions to modified gravity scenarios.
