... results are given in Sect. 3.2 and Appendix A.2. To study the effects of different energy-loss mechanisms and their impacts on the emission signatures, we introduced 2 × 10 5 number of macro-particles at the initial time of the simulation. The distribution of the Lagrangian particles allows a complete sampling of the system, as shown in Fig. 2. Here, the particles are coloured based on their unique identity, ranging from 1 to the maximum number of macro-particles. The background on which these particles are over-plotted represents the fluid density in grayscale. The left and right panels of Fig. 2 are the snapshots taken at times t/t sc = 150 and 200, respectively. The ...

The left and right panels of Fig. 2 are the snapshots taken at times t/t sc = 150 and 200, respectively. The combined evolution of Lagrangian macro-particles and the fluid density from our 2D runs clearly shows that the slab jet is sufficiently sampled during the evolution. Further, one can observe that the vortices of the KHI are responsible for mixing the particles ...

... shocked, we have initially chosen a steeper index. The synchrotron emissivity for an initial power law particle spectra is calculated using Eq. (37) of Vaidya et al. (2018) and the EC emissivity is calculated using Eq. (8) of Sect. 2.2. All the emissions are obtained at the time t/t sc = 200 (particle distribution is shown in the right panel of Fig. 2) with an observer making a 5 • angle with respect to the z-axis (pointing out of the ...

... case since the EC component of the spectra becomes broader. With change in the temperature of the photon field or the κ values, the energy loss rate of the emitting particles changes. Such effects of photon field temperature and κ values can be seen from the cooling timescale (see Fig. A.1) and the time-evolving particle spectra (refer Fig. A.2). As we decrease the temperature of the photon field, the loss due to EC also decreases. As a result, it demonstrates a substantial effect on the low-energy hump as well as the high-energy hump of the SED. Due to less EC loss, a larger number of highly energetic particles will be present to emit synchrotron emission up to 10 15 Hz. With ...

... limit (≈γ Θ 1), electrons lose energy like synchrotron process and in the Klein-Nishina limit (≈γ Θ 1), the loss mechanism follows a logarithmic profile. Furthermore, we have performed 2D toy model simulations that are focused on validating our numerical algorithm and understanding the effects of various parameters on the particle spectra (see Fig. A.2) and multi-band emissions (see Fig. ...
