M31:近距离的观测表明,仙女座星系的黑洞没有我们想象的那样“冷”
译:Jack
钱德拉和哈勃太空望远镜最近观测了两个发光的球状星团(我们这么说,是因为他们
的形状是球形的),我们通常用它来定位仙女座星系的X-射线源,这样做的精确度要比以
前高10倍左右。图片中我们可以看见三个钱德拉辐射源,这三个辐射源距离中心黑洞很近
,我们已经在哈勃图片中放大并且用等高线(红色)标示了出来。一般都认为黑洞存在于
花生状的等高线的中央,也就是在三个钱德拉辐射源的北部。

这样高的观测精度告诉我们:以前我们将较冷的X-射线源和中心黑洞溶为一体,而且
这些东西处于星系的中央,这种想法是错误的;实际上这些东西在中心以南10光年。第二
,就是发现了较热的X-射线源和黑洞是在同一个位置。在这张图片中,那两个球状星团在
图片中我们是看不见的。

一个遥远的类星体及其前景星系
译:Shea
这是一张类星体PKS1127-145的X射线照片,它是一个非常亮的X射线以及可见光源,
离开地球大约100亿光年,从类星体延伸出的喷流至少有1百万光年。这一喷流可能是由高
能电子和微波光子碰撞而形成的。
环绕超大质量黑洞的气体的爆发性活动可能引发了这一喷流。从喷流的长度以及观测
到的X射线的亮度来判断,爆发性活动是长期的,但是有间歇。

当这个类星体的X射线射向地球时,会穿过一个40亿光年远的星系。这个星系中不同
的原子会吸收X射线,造成一个亮度变弱的类星体像,或者说它制造了一个X射线阴影。相
同的,当X射线照射我们的身体时,我们的骨骼也会产生一个X射线阴影。通过测量X射线
吸收的量,天文学家估计出,40亿年前,这个星系中的氧与氢的浓度比比银河系低5倍。
这些观测可以是天文学家认识到氧在星系中是如何积累的。

这些炽热的气体会进入星系的其他部分。外流的气体,夹杂着恒星毁灭时抛出的化学

Astronomers think they've found two "quark stars."
by Vanessa Thomas
The Chandra X-ray Observatory has examined two weird objects that should look
like neutron stars, but don't. They appear to be incredibly dense — too dense
even for neutron stars. Astronomers suspect the objects are composed of a new
type of matter made simply of quarks, the most basic subatomic particles
known.

The apparent discovery, made with NASA's orbiting Chandra X-Ray Observatory,

from backyard scopes to the Hubble Space Telescope.

来自主题: Astronomy版 - 天文研究用的照片有做叠加吗?
叠加的主要好处是可以增加探测效率
首先要知道所谓detection, 指的是S/N大于某个阈值,比如说5sigma detection
指S/N>5. 现在假设你有单张image,有个源的信噪比是1,那你不能说是5sigma
detection.
但是如果你拍了很多张同样曝光时间的image并叠加的话,你的信噪比会提高,因为信
号总是在那儿的而随机error会降低,就好像重复试验降低统计误差一样。所以单张
image上不够5sigma detection的源,叠加的够多了就可能可以。
有时候还必须要把单张曝光时间拆成多次曝光,之后再叠加,这样做的目的就是像
chandra说的,方便扣cosmic ray, 避免背景饱和等等。有的时候还可以dither多次曝
光,
可以更好的扣天光背景(尤其是近红外),避免目标源落在CCD坏点上,或者更好的
spatially sample PSF等等.
