WMAP平面异常信号模型

A Model For The WMAP Anomalous Ecliptic Plane Signal

H. N. Sharpe

摘要:

本文提出了一个简单的模型来解释Diego等人(2009)最近报道的WMAP数据中的高银河纬度异常。据认为,从热谱的异常偏离可能是由背景热辐射通过前景光学薄HII云的传播。背景辐射可能是与来自Sgr A* 的一度活跃的喷流有关的冷却射电瓣的残余。

英文摘要:

A simple model is presented to explain the high Galactic latitude anomalies in the WMAP data recently reported by Diego et al (2009). It is suggested that the anomalous deviation from a thermal spectrum could be caused by the propagation of background thermal radiation through a foreground optically thin HII cloud. The background radiation may be the remnant of cooling radio lobes associated with once-active jets from Sgr A*.
