Tleco: A Toolkit for Modeling Radiative Signatures from Relativistic Outflows

Zachary Davis, Jesús M. Rueda‐Becerril, Dimitrios Giannios

Abstract A wide range of astrophysical sources exhibit extreme and rapidly varying electromagnetic emission indicative of efficient nonthermal particle acceleration. Understanding these sources often involves comparing data with a broad range of theoretical scenarios. To this end, it is beneficial to have …

Tleco: A Toolkit for Modeling Radiative Signatures from Relativistic Outflows

Zachary Davis, Jesús M. Rueda‐Becerril, Dimitrios Giannios

A wide range of astrophysical sources exhibit extreme and rapidly varying electromagnetic emission indicative of efficient non-thermal particle acceleration. Understanding these sources often involves comparing data with a broad range of theoretical scenarios. To this end, it is beneficial to have tools …

Handing off the outcome of binary neutron star mergers for accurate and long-term postmerger simulations

Federico G. Lopez Armengol, Z. B. Etienne, Scott C. Noble, Bernard Kelly et autres

We perform binary neutron star (BNS) merger simulations in full dynamical general relativity with illinoisgrmhd, on a Cartesian grid with adaptive-mesh refinement. After the remnant black hole has become nearly stationary, the evolution of the surrounding accretion disk on Cartesian grids over …

Balancing turbulent heating with radiative cooling in blazars

Zachary Davis, Jesús M. Rueda‐Becerril, Dimitrios Giannios

ABSTRACT Recently, particle-in-cell (PIC) simulations have shown that relativistic turbulence in collisionless plasmas can result in an equilibrium particle distribution function where turbulent heating is balanced by radiative cooling of electrons. Strongly magnetized plasmas are characterized by higher energy peaks and broader …

HARM3D+NUC: A New Method for Simulating the Post-merger Phase of Binary Neutron Star Mergers with GRMHD, Tabulated EOS, and Neutrino Leakage

Ariadna Murguia-Berthier, Scott C. Noble, Luke F. Roberts, Enrico Ramirez-Ruiz et autres

Abstract The first binary neutron star merger has already been detected in gravitational waves. The signal was accompanied by an electromagnetic counterpart including a kilonova component powered by the decay of radioactive nuclei, as well as a short γ-ray burst. In order …

A numerical approach for radiative cooling in relativistic outflows

Jesús M. Rueda‐Becerril

Abstract In high‐energy astrophysics scenarios such as Blazars, gamma‐ray bursts, or pulsar wind nebulae, it is highly probable that ultrarelativistic particles interact with photons in their environment through scattering. As long as the energy of the particle is greater than the energy …

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 instance, flat‐spectrum radio quasars (FSRQs), the most powerful jets, manage to accelerate to …

Blazar jets launched with similar energy per baryon, independently of their power

Jesús M. Rueda‐Becerril, Amanda O. Harrison, Dimitrios Giannios

ABSTRACT The most extreme active galactic nuclei are the radio active ones whose relativistic jet propagates close to our line of sight. These objects were first classified according to their emission-line features into flat-spectrum radio quasars (FSRQs) and BL Lacertae objects (BL …

Baryon loading of blazar jets independent of accretion rate, not so their luminosity

Jesús 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 to their emission line features into flat-spectrum radio quasars (FSRQs) and BL Lacertae objects …

Inverse Compton signatures of gamma-ray burst afterglows

Hao Zhang, Ian Christie, Maria Petropoulou, Jesús M. Rueda‐Becerril et autres

ABSTRACT The afterglow emission from gamma-ray bursts (GRBs) is believed to originate from a relativistic blast wave driven into the circumburst medium. Although the afterglow emission from radio up to X-ray frequencies is thought to originate from synchrotron radiation emitted by relativistic, …
