Radiation Signatures From Striped Blazar Jet
Haocheng Zhang, Dimitrios Giannios
Relativistic jets from supermassive black holes are among the most powerful and luminous astrophysical systems in Universe. We propose that the open magnetic field lines through th…
The blazar sequence revised
Jesús M. Rueda-Becerril, Amanda O. Harrison, Dimitrios Giannios
We propose and test a fairly simple idea that could account for the blazar sequence: all jets are launched with similar energy per baryon, independently of their power. For instanc…
Shock-powered radio precursors of neutron star mergers from accelerating relativistic binary winds
Navin Sridhar, Jonathan Zrake, Brian D. Metzger +2
During the final stages of a compact object merger, if at least one of the binary components is a magnetized neutron star (NS), then its orbital motion substantially expands the NS…
Multimessenger parameter estimation of GW170817: from jet structure to the Hubble constant
Hao Wang, Dimitrios Giannios
The electromagnetic radiation that followed the neutron star merger event GW170817 revealed that gamma-ray burst afterglows from jets misaligned with our line of sight exhibit a li…
Blazar jets launched with similar energy per baryon, independently of their power
Jesus M. Rueda-Becerril, Amanda O. Harrison, Dimitrios Giannios
The most extreme active galactic nuclei (AGN) are the radio active ones whose relativistic jet propagates close to our line of sight. These objects were first classified according…
Radiation and Polarization Signatures from Magnetic Reconnection in Relativistic Jets--I. A Systematic Study
Haocheng Zhang, Xiaocan Li, Dimitrios Giannios +3
Blazars are relativistic magnetized plasma outflows from supermassive black holes that point very close to our line of sight. Their emission is nonthermal dominated and highly vari…
