一个极高光度IRAS星系样本在20cm观测的初步结果

Preliminary Results of 20cm Observations on an Ultraluminous IRAS Galaxy Sample

使用澳大利亚致密阵 (ATCA)在 1 .4GHz上观测了一个极高光度的IRAS星系样本。在这个样本所包括的 3 7个IRAS星系中 ,探测到 1 9个源的射电发射 ,获得了它们的射电参数 ,如峰值位置 ,射电流量等。该样本的射电功率范围在 2 2 .9<logP1 .4G(W /Hz) <2 3 .8,本文给出了观测的初步结果。

An ultraluminous IRAS galaxy sample was observed at 1.4 GHz wavelength by using the Australia Telescope Compact Array(ATCA).Radio emission was detected from 19 sources in the 37 IRAS galaxy sample.The radio parameters,for example,peak position,radio flux,etc.are obtained.The radio power of the sample is in the range 22.9<log P 1.4GHz (W/Hz)<23.8.Preliminary results of the observations are given in the paper.
