We present a complete solution to the cyclotron-synchrotron radiation due to an isotropic distribution of electrons moving in a magnetic field. We make no approximations in the calculations other than artificially broadening the harmonics by a small amount in order to facilitate the numerics. In contrast to previous calculations, we sum over all relevant harmonics and integrate over all particle and observer angles relative to the magnetic field. We present emission spectra for electron…

Time-dependent Numerical Model for the Emission of Radiation from Relativistic Plasma
We describe a numerical model constructed for the study of the emission of radiation from relativistic plasma under conditions characteristic of, e.g., gamma-ray bursts and active galactic nuclei.
Thermal synchrotron radiation and its Comptonization in compact X-ray sources
We investigate the process of synchrotron radiation from thermal electrons at semirelativistic and relativistic temperatures. We find an analytic expression for the emission coefficient for random
Cyclotron-synchrotron: Harmonic fitting functions in the non-relativistic and trans-relativistic regimes
The present work investigates the calculation of absorption and emission cyclotron line profiles in the non-relativistic and trans-relativistic regimes. We provide fits for the ten first harmonics
Radiative, two-temperature simulations of low luminosity black hole accretion flows in general relativity
We present a numerical method which evolves a two-temperature, magnetized, radiative, accretion flow around a black hole, within the framework of general relativistic radiation magnetohydrodynamics.
A MODEL FOR EMISSION FROM JETS IN X-RAY BINARIES: CONSEQUENCES OF A SINGLE ACCELERATION EPISODE
There is strong evidence for powerful jets in the low/hard state of black hole X-ray binaries (BHXRBs). Here, we present a model in which electrons are accelerated once at the base of the jet, and
Prompt Gamma-Ray Burst Spectra: Detailed Calculations and the Effect of Pair Production
We present detailed calculations of the prompt spectrum of γ-ray bursts (GRBs) predicted within the fireball model framework, in which emission is due to internal shocks in an expanding relativistic
Are Particles in Advection-dominated Accretion Flows Thermal?
We investigate the form of the momentum distribution function for protons and electrons in an advection-dominated accretion flow (ADAF). We show that for all accretion rates, Coulomb collisions are
The Role of Magnetic Field Dissipation in the Black Hole Candidate Sagittarius A*
The compact, nonthermal radio source Sgr A* at the Galactic center appears to be coincident with a ~2.6 × 106 M☉ pointlike object. Its energy source may be the release of gravitational energy as gas
Polarized Synchrotron Emissivities and Absorptivities for Relativistic Thermal, Power-Law, and Kappa Distribution Functions
Synchrotron emission and absorption determine the observational appearances of many astronomical systems. In this paper, we describe a numerical scheme for calculating synchrotron emissivities and
Thermal Electrons in Mildly Relativistic Synchrotron Blast Waves
Numerical models of collisionless shocks robustly predict an electron distribution composed of both thermal and nonthermal electrons. Here, we explore in detail the effect of thermal electrons on the
