Vortex-reconnection energy bounds in Bose-Einstein-condensed and superfluid dark matter halos
Kazım Yavuz Ekşi
Bose-Einstein-condensed (BEC) and superfluid dark-matter (SFDM) halos can contain coherent, wave-supported cores whose angular momentum is carried by quantized vortices. When vorti…
An energy approach to pulsar-disc interaction: disc stability and implications for transitional millisecond pulsars
Eda Vurgun, Domingo García-Senz, Manuel Linares +1
The stability of an accretion disc surrounding a millisecond pulsar is analysed from an energetic point of view, using magnetohydrodynamic simulations that consider realistic disc…
Angular Dependence of Coherent Radio Emission from Magnetars with Multipolar Magnetic Fields
Shotaro Yamasaki, Kazim Yavuz Eksi, Ersin Gogus
The recent detection of a Fast Radio Burst (FRB) from a Galactic magnetar secured the fact that neutron stars (NSs) with super-strong magnetic fields are capable of producing these…
Ricci-Determinant Gravity: Dynamical Aspects and Astrophysical Implications
Hemza Azri, K. Yavuz Ekşi, Canan Karahan +1
The Palatini gravitational action is enlarged by an arbitrary function of the determinants of the Ricci tensor and the metric, . The res…
On the Magnetic Fields, Beaming Fractions, and Fastness Parameters of Pulsating Ultra-Luminous X-Ray Sources
M. H. Erkut, M. M. Türkoğlu, K. Y. Ekşi +1
The discovery of pulsating ultra-luminous X-ray sources (PULX) suggests that neutron stars are presumably common within the ultra-luminous X-ray source (ULX) population though the…
The initial evolution of millisecond magnetars: an analytical solution
Sercan Çıkıntoğlu, Sinem Sasmaz Mus, K. Yavuz Ekşi
Millisecond magnetars are often invoked as the central engine of some gamma-ray bursts (GRBs), specifically the ones showing a plateau phase. We argue that an apparent plateau phas…
