恒定变化的无线电测量和用ALMA进行的展望
Radio measurements of constant variation, and perspectives with ALMA
摘要:
本文评述了射电范围内基本常数变化(α和μ)的现有限制,这些限制主要来自中z到高z星系类星体前的吸收线,通过CO,HI,OH,HCO+,HCN。连接到NH3和CII。有了ALMA,探测窄带射电连续谱源的灵敏度将提高一个数量级,预期的进展是量化的。强调了无线电域相对于光域的相对优势。
英文摘要:
The present constraints on fundamental constant variation (αand μ) obtained in the radio range are reviewed, coming essentially from absorption lines in front of quasars of intermediate to high-z galaxies, through CO, HI, OH, HCO+, HCN .. lines up to NH3 and CII. With ALMA, the sensitivity to detect radio continuum sources in narrow bands will increase by an order of magnitude, and the expected progress is quantified. The relative advantage of the radio domain with respect to the optical one is emphasized.
