Relativistic \(^{56}\text{Ni}\) Decay Lines in GRB 221009A
Rahim Moradi, Emre S. Yorgancioglu, Shao-Lin Xiong +4
Long Gamma Ray Bursts are thought to originate from the core collapse of massive stars that give rise to energetic broad-lined Type Ic supernovae. The brightest burst ever recorded…
An Accretion-Modulated Internal Shock Model for Long GRBs
R. Moradi, C. W. Wang, E. S. Yorgancioglu +1
We introduce the Accretion-Modulated Internal Shock model (AMIS) as a possible framework for explaining the observational properties of long gamma-ray burst (GRB) prompt emission.…
Constraining the Neutron-Star Equation of State via Short Gamma-Ray Burst X-ray Afterglows
R. Moradi, Y. Wang, F. Rastegarnia +4
Recent observations from NICER in X-rays and LIGO/Virgo in gravitational waves have provided critical constraints on the mass, radius, and tidal deformability of neutron stars, imp…
Can GRB Empirical Correlations Be Used for Population Studies?
Emre S. Yorgancioglu, Yun-Fei Du, Shu-Xu Yi +1
Only a small fraction of Gamma-ray bursts (GRBs) have independent redshift measurements, which are essential for understanding their intrinsic properties. For this reason, empirica…
Investigating the Dainotti Relation in Gamma-Ray Bursts through Multipolar Electromagnetic Radiation
Emre S. Yorgancioglu, Daban Mohammed Saeed, Rahim Moradi +1
The Dainotti relation empirically connects the isotropic plateau luminosity () in gamma-ray bursts (GRBs) X-ray afterglows to the rest-frame time at which the plateau ends ($T…
A systematic study of binary neutron star merger rate density history using simulated gravitational wave and short gamma-ray burst observations
Yun-Fei Du, Emre Seyit Yorgancioglu, Shu-Xu Yi +2
Measuring the merger rate density history of binary neutron stars (BNS) can greatly aid in understanding the history of heavy element formation in the Universe. Currently, second-g…
