星系中的射电辐射主要有三种
- 同步辐射 (低频,幂律谱)
- 自由-自由散射 (HII区:低频是接近于热谱,光学厚,高频光学薄,平谱)
- AME
- Anomalous Microwave Emission (AME) is a component of diffuse Galactic radiation observed at frequencies in the range ≈ 10–60 GHz. AME was first detected in 1996 and recognised as an additional component of emission in 1997
