Summary: In this study, the merging process of magnetized plasma jets was modeled using fully kinetic particle-in-cell simulations. The modified two-stream instability was identified as the main mechanism responsible for stopping the plasma jets and preventing species interpenetration. The results showed that the merged plasma had electron and ion Hall parameters greater than unity and a plasma beta close to unity, which are desired characteristics for PLX experiments. Additionally, the 2D simulations validated the results of the radiation magneto-hydrodynamics code FLASH, which will be used for modeling future PJMIF experiments.

Summary: Time-dependent gasdynamic parameters of high-speed aluminum plasma jets injected into the ionosphere were obtained through numerical simulations, which agree with measurement data of gasdynamic and radiation characteristics of the plasma in laboratory and ionospheric experiments.

Summary: The laboratory simulation of jets from young stars was conducted to investigate the spatial structure of plasma jets in different gases. The results show that pure neon gas produces the most structured plasma flow, while pure helium gas shows the least structured flow. However, adding a small amount of neon to helium significantly alters the shape of the plasma ejection head and introduces noticeable small-scale structures. It is suggested that these differences are related to the cooling efficiency and the presence of instabilities in the plasma. In addition, multiple blobs propagating parallel to each other can be observed in some cases, leading to the formation of a lace-like structure in the plasma ejection.

Summary: The study compared the results of different hydrodynamic approaches in computing a simplified one-dimensional model of a type II supernova during the free expansion stage, showing good agreement in profiles of physical quantities and light curves. Additionally, it demonstrated that the light curve of such type II supernova in the UX band exhibits a characteristic double-peaked structure.

Summary: Experiments were conducted to investigate the X-ray self-emission of plasma in heated targets composed of layers of different materials. The study found that materials with high atomic number Z contribute significantly to the self-emission of the target.

Summary: This work discusses the determination of radiation-gas-dynamic parameters of a high-speed aluminum plasma jet injected into the ionosphere using the explosive cumulative generator VGPS-300. The algorithm for calculating these parameters is described, and the numerical simulation results for the initial stage of the jet plasma dynamics are consistent with evidence from laboratory experiments and ionospheric experiments Fluxus.
