具有CMB极化的早期宇宙

Early Universe with CMB polarization

Tarun Souradeep

摘要:

宇宙是人类心灵可以努力理解自然的最宏伟的可想象的尺度。宇宙学是试图理解宇宙起源和演化的科学分支,它的惊人之处在于,它在很大程度上可以通过应用我们用于其他物理学分支的相同物理学基本定律来理解。观测到的宇宙微波背景(CMB)是通过应用辐射过程和传输的基本定律来理解的,这些基本定律在经典的S。在宇宙学的背景下。除了现在广受好评的温度各向异性,还有线性偏振信息印在观测到的宇宙微波背景。CMB极化已经解决了,并承诺做更多的事情,以解开关于接近宇宙起源的物理学的最深层次的基本问题。

英文摘要:

The Universe is the grandest conceivable scale on which the human mind can strive to understand nature. The amazing aspect of cosmology, the branch of science that attempts to understand the origin and evolution of the Universe, is that it is largely comprehensible by applying the same basic laws of physics that we use for other branches of physics. The observed cosmic microwave background (CMB) is understood by applying the basic laws of radiative processes and transfer, masterfully covered in the classic text by S. Chandrasekhar, in the cosmological context. In addition to the now widely acclaimed temperature anisotropy, there is also linear polarization information imprinted on the observed Cosmic Microwave background. CMB polarization already has addressed, and promises to do a lot more, to unravel the deepest fundamental queries about physics operating close to the origin of the Universe.
