The High-Energy Light Isotope eXperiment (HELIX) Instrument
P. S. Allison, M. Baiocchi, J. J. Beatty +27
The HELIX detector is a balloon-borne instrument designed to measure the flux of light (Z < 11) cosmic-ray isotopes. In this paper we describe the initial configuration of HELIX, o…
The emergence of X-ray emission lines during relativistic radio-jet formation in the changing-look active galactic nucleus 1ES 1927+654
Dev R. Sadaula, Sibasish Laha, Eileen T. Meyer +27
We present results from a comprehensive multi-wavelength monitoring campaign of the changing-look active galactic nucleus 1ES 1927+654 during the onset and evolution of a relativis…
Hadronic Processes, Plasma Evolution and Neutrino Emission in Magnetic Towers of Neutron-Star Merger Remnants
Rostom Mbarek, Jiaxi Wu, Elias R. Most
Binary neutron star mergers can form short-lived magnetar-like remnants whose magnetically dominated polar towers reach --, but the microphysical…
On The Nonthermal Power Laws In Magnetized Turbulent Plasmas
Rostom Mbarek, Daniel Grošelj, Alexander Philippov
Building on recent progress in the understanding of particle transport in magnetized plasmas, we derive a scaling law for the formation of nonthermal spectral tails in mildly and s…
Particle Acceleration, Coronal Neutrino Production, and the Diffuse Extragalactic Neutrino Background from Supermassive Black Holes
Rostom Mbarek
We present a generalized neutrino luminosity function for protons accelerated in the X-ray coronae of supermassive black holes in Seyfert-like galaxies. A major uncertainty in asse…
An outflow from the X-ray corona as the origin of millimeter emission from radio-quiet AGN
A. Hankla, A. Philippov, R. Mbarek +4
Recent observations of radio-quiet active galactic nuclei (RQAGN) have shown the presence of millimeter emission, whose origin remains unknown, from within parsec scales of the cen…
