Rho, J.; Dyer, K. K.; Borkowski, K. J.; Reynolds, S. P., 2002, "X-ray synchronization emitting Fe-rich ejecta in SNR RCW 86", https://hdl.handle.net/2014/9653, Astrophysical journal, JPL Open Repository
Supernova remnants may exhibit both thermal and nonthermal X-ray emission. In a previous study with ASCA data, we found that the middle-aged supernova remnant RCW 86 showed evidence for both processes, and predicted that observations with much higher spatial resolution would dist... |

Chen, Jacqueline C.; Stanton, Philip H., 1994, "X/Ka-Band Dual Frequency Horn Design", https://hdl.handle.net/2014/36302, Seattle, Washington, USA, JPL Open Repository
The Deep Space Network has a need for a dual frequency horn for simulation dual frequency operation in a beam waveguide antenna. The dual frequency horn will receive X-band (8.4-8.5 GHz), KABLE frequency (33.6-33.8 GHz), and DSN Ka-band downlink (31.8-32.3 GHz) signals simultaneo... |
