Magnetosphere Evolution and Precursor-Driven Electromagnetic Signals in Merging Binary Neutron Stars
Dimitrios Skiathas, Constantinos Kalapotharakos, Zorawar Wadiasingh +3
We detail new force-free simulations to investigate magnetosphere evolution and precursor electromagnetic (EM) signals from binary neutron stars. Our simulations fully follow a rep…
Combined magnetic field evolution in neutron star cores and crusts: Ambipolar diffusion, Hall effect and Ohmic dissipation
Dimitrios Skiathas, Konstantinos N. Gourgouliatos
Neutron star magnetic field evolution is mediated through the Hall effect and Ohmic dissipation in the crust while ambipolar diffusion is taking place in the core. These effects ha…
A Third Epoch Proper Motion Study of The Forward Shock in Kepler's Supernova Remnant
Sadie C. Coffin, Brian J. Williams, Satoru Katsuda
We present measurements of the expansion of Kepler's Supernova Remnant (SNR) over three epochs of Chandra X-ray observations from 2000, 2006, and 2014. As the remnant of a historic…
Fitting strategies of accretion column models and application to the broadband spectrum of Cen X-3
Philipp Thalhammer, Matthias Bissinger, Ralf Ballhausen +10
Due to the complexity of modeling the radiative transfer inside the accretion columns of neutron star binaries, their X-ray spectra are still commonly described with phenomenologic…
Systematic search for gamma-ray periodicity in active galactic nuclei detected by the Fermi Large Area Telescope
P. Peñil, A. Domínguez, S. Buson +8
We use nine years of gamma-ray data provided by the Fermi Large Area Telescope (LAT) to systematically study the light curves of more than two thousand active galactic nuclei (AGN)…
NuSTAR Observations and multi-wavelength modeling of the high-redshift BL Lac Object 4FGL J2146.5-1344
M. Rajagopal, L. Marcotulli, M. Ajello +3
High synchrotron peak (HSP; Hz) BL Lacs are some of the most extreme accelerators in the Universe. Those found at high redshifts () challenge our under…
