摘要
梅西耶104,NGC 4594，也被称为草帽星系，已经被广泛研究，特别是它的结构和恒星晕。它丰富的球状星团已经产生了许多理论和猜测。然而，在这样一个壮观的星系附近的其他物体有时会被忽略。在研究HST遗产网站上提供的M104光环(HST提案9714,PI: Keith Noll)的HST图像时，作者在2000年的12:40:07.829 -11:36:47.38观测到一个直径约为4角秒的物体。用VO工具进行的一项研究表明，该物体是一个具有AGN (Seyfert)的SBc星系。
Messier 104, NGC 4594, also known as the Sombrero Galaxy, has been extensively studied, especially its structure and stellar halo. Its abundance of globular clusters has given rise to many theories and much speculation. However, other objects in the vicinity of such a spectacular galaxy are sometimes ignored. While studying HST images available on the HST Legacy website of the halo of M104 (HST proposal 9714, PI: Keith Noll), the author observed at 12:40:07.829 -11:36:47.38 (in j2000) an object about 4 arc seconds in diameter. A study with VO tools suggests that the object is a SBc galaxy with an AGN (Seyfert).
