EVN对IRAS 23365+3604的三个历元观测
Three epochs of EVN observations towards IRAS 23365+3604
摘要：
欧洲VLBI观测网（EVN）为我们研究发光和超铝红外星系核和核周区域提供了必要的灵敏度和角分辨率。这些星系的高恒星形成率（SFR）意味着存在大量的大质量恒星和致密的周围介质。因此，预计会出现明亮的射电超新星。为了通过核心坍缩超新星（CCSN）探测来估计ULIRGs中的SFR，我们开始了与EVN一起对本地宇宙中最亮和最远的ULIRGs的小样本进行观测活动。在这里，我们提出了我们的结果，从三个时代的准同时观测与EVN在6和18厘米对我们的样本中的对象之一：IRAS 23365+3604。
英文摘要：
The European VLBI Network (EVN) provides us with the necessary sensitivity and angular resolution to study the nuclear and circumnuclear regions in Luminous and Ultraluminous Infrared Galaxies. The high Star Formation Rates (SFR) inferred for these galaxies implies both the presence of a high number of massive stars and a dense surrounding medium. Therefore, bright radio SNe are expected to occur. With the aim of estimating the SFR in ULIRGs by means of Core Collapse supernova (CCSN) detections, we started an observing campaign with the EVN on a small sample of the brightest and farthest ULIRGs in the local Universe. We present here our results from three epochs of quasi-simultaneous observations with the EVN at 6 and 18 cm towards one of the objects in our sample: IRAS 23365+3604.
