Abstract The young shell-type supernova remnant RCW 103 has peculiar properties in the X-ray morphology obtained with Chandra. southeastern shell is brighter X-rays, and curved border of this region flatter than other part.We investigate formation periphery using 3D hydrodynamical simulation. Assuming that ejecta been evolved medium a density gradient, detected shape can be generally reproduced...

ABSTRACT We study molecular emission in a massive condensation at the border of H ii region RCW 120, paying particular attention to Core 1 and 2 objects, most fragments found previously by ALMA. The latter fragment was suggested host high-mass analogue Class 0 young stellar object. present spectra mm range made with APEX telescope. detect CH3OH C34S lines Cores 2. CH3CN series SO2 are only esti...

Abstract The physics of particle acceleration at supernova remnant (SNR) shocks is one the most intriguing problems in astrophysics. SNR RCW 86 provides a suitable environment for understanding because can extract information on both accelerated particles and same regions through bright X-ray emission. In this work, we study proper motions spectral properties southwestern region 86. motion velo...
