The ages of the oldest astrophysical objects in an ellipsoidal universe
Binici, Selinay Sude; Deliduman, Cemsinan; Dilsiz, Furkan Sakir (Elsevier, 2024)James Webb Space Telescope's (JWST) observations since its launch have shown us that there could be very massive and very large galaxies, as well as massive quasars very early in the history of the Universe, conflicting ... -
Alternatif yerçekimi kuramlarının astrofiziksel uygulamaları
Kaşıkçı, Oğuzhan (Mimar Sinan Güzel Sanatlar Üniversitesi, 2019)[Abstract Not Available] -
Astrophysics with Weyl gravity
Deliduman, Cemsinan; Kasikci, Oguzhan; Yapiskan, Baris (World Scientific Publ Co Pte Ltd, 2018)We aim to explain some astrophysical phenomena in low density astronomical regions without invoking dark matter. We propose that the effective theory of gravity could have individual terms which become dominant in respective ... -
Constraints on perturbative f(R) gravity via neutron stars
Arapoglu, Savas; Deliduman, Cemsinan; Eksi, K. Yavuz (Iop Publishing Ltd, 2011)We study the structure of neutron stars in perturbative (R) gravity models with realistic equations of state. We obtain mass-radius relations in a gravity model of the form f(R) = R + alpha R-2. We find that deviations ... -
Einstein-Weyl-Eddington kuramında Noether simetrisi
Dilsiz, Furkan Şakir (Mimar Sinan Güzel Sanatlar Üniversitesi, 2021)Einstein'in Genel Görelilik kuramı yerçekimsel olayları açıklamada oldukça başarılı olsa da açıklamada yetersiz kaldığı bazı önemli problemler vardır. Kuramsal açıdan bakıldığında, Genel Görelilik kuramının renormalize ... -
Emergence of correlated proton tunnelling in water ice
Pusuluk, Onur; Farrow, Tristan; Deliduman, Cemsinan; Vedral, Vlatko (Royal Soc, 2019)Several experimental and theoretical studies report instances of concerted or correlated multiple proton tunnelling in solid phases of water. Here, we construct a pseudo-spin model for the quantum motion of protons in a ... -
f(R) gravity in an ellipsoidal universe
Deliduman, Cemsinan; Kasikci, Oguzhan; Tugyanoglu, Vildan Keles (Elsevier, 2024)We propose a new model of cosmology based on an anisotropic background and a specific f ( R ) theory of gravity. It is shown that field equations of f ( R ) gravity in a Bianchi type I background give rise to a modified ... -
Flat galactic rotation curves from geometry in Weyl gravity
Deliduman, Cemsinan; Kasikci, Oguzhan; Yapiskan, Baris (Springer, 2020)We searched for a resolution of the flat galactic rotation curve problem from geometry instead of assuming the existence of dark matter. We observed that the scale independence of the rotational velocity in the outer region ... -
Gravitational lensing in Weyl gravity
Kasikci, Oguzhan; Deliduman, Cemsinan (Amer Physical Soc, 2019)We calculate the deflection angle of light from a distant source by a galaxy cluster in Weyl's conformal gravity. The general method of calculation is first applied to calculate the deflection angle in Schwarzschild-de ... -
Kuadratik genelçekim kuramında karadelik çözümleri ve entropi
Helva, Mehmet (T.C. Mimar Sinan Güzel Sanatlar Üniversitesi Fen Bilimleri Enstitüsü, 2015)[Abstract Not Available] -
A massive S-duality in four dimensions
Catal-Ozer, Aybike; Deliduman, Cemsinan; Saka, E. Ulas (Springer, 2011)We reduce the Type IIA supergravity theory with a generalized Scherk-Schwarz ansatz that exploits the scaling symmetry of the dilaton, the metric and the NS 2-form field. The resulting theory is a new massive, gauged ... -
Neutron star solutions in perturbative quadratic gravity
Deliduman, Cemsinan; Eksi, K. Y.; Keles, Vildan (Iop Publishing Ltd, 2012)We study the structure of neutron stars in R vertical bar beta R-mu nu R-mu nu gravity model with perturbative method. We obtain mass-radius relations for six representative equations of state (EoSs). We find that, for ... -
Neutron Stars as Laboratories for Gravity Physics
Deliduman, Cemsinan (Amer Inst Physics, 2014)We study the structure of neutron stars in R + alpha R-2 gravity model with perturbative method. We obtain mass-radius relations for four representative equations of state (EoS). We find that, for vertical bar alpha vertical ... -
Neutron stars in a perturbative f(R) gravity model with strong magnetic fields
Cheoun, Myung-Ki; Deliduman, Cemsinan; Gungor, Can; Keles, Vildan; Ryu, C. Y.; Kajino, Toshitaka; Mathews, Grant J. (Iop Publishing Ltd, 2013)In Kaluza-Klein electromagnetism it is natural to associate modified gravity with strong electromagnetic fields. Hence, in this paper we investigate the combined effects of a strong magnetic field and perturbative f(R) ... -
Nötron yıldızlarında materyal özelliklerinin sınıflandırılması
Helva, Mehmet (Mimar Sinan Güzel Sanatlar Üniversitesi, Fen Bilimleri Enstitüsü, 2024)Kompakt yıldızlar yüksek yoğunluk değerlerine sahip astrofiziksel nesnelerdir. Bu yüksek yoğunluktaki ortamda maddenin nasıl davrandığı ancak altında yatan mikroskobik teorilerin anlaşılmasıyla mümkündür. Bu teoriler, ... -
Proton tunnelling in hydrogen bonds and its implications in an induced-fit model of enzyme catalysis
Pusuluk, Onur; Farrow, Tristan; Deliduman, Cemsinan; Burnett, Keith; Vedral, Vlatko (Royal Soc, 2018)The role of proton tunnelling in biological catalysis is investigated here within the frameworks of quantum information theory and thermodynamics. We consider the quantum correlations generated through two hydrogen bonds ... -
Quantum entanglement shared in hydrogen bonds and its usage as a resource in molecular recognition
Pusuluk, Onur; Torun, Gokhan; Deliduman, Cemsinan (World Scientific Publ Co Pte Ltd, 2018)Quantum tunneling events occurring through biochemical bonds are capable of generating quantum correlations between bonded systems, which in turn makes the conventional second law of thermodynamics approach insufficient ... -
Spherical and cylindrical solutions in f(T) gravity by Noether symmetry approach
Nurbaki, Ali Nur; Capozziello, Salvatore; Deliduman, Cemsinan (Springer, 2020)We find exact solutions for f(T) teleparallel gravity for the cases of spherically and cylindrically symmetric tetrads. The adopted method is based on the search for Noether symmetries of point-like Lagrangians defined in ... -
