螺旋星系的毫米到厘米的SED。NIKA2和SRT工具之间的协同作用
The mm-to-cm SED of spiral galaxies. Synergies between NIKA2 and SRT instruments
摘要:
螺旋星系的光谱能量分布的毫米到厘米的范围在很大程度上还没有被探索。它的覆盖范围需要解开尘埃排放,自由和同步辐射的贡献,并可以提供尘埃模型,恒星形成率和ISM属性的限制。我们提出的情况下,NIKA2观测附近的螺旋和那些从计划和目前的仪器在撒丁岛射电望远镜之间的协同作用,并报告一个试点K波段计划,以寻找异常微波发射,一个难以捉摸的发射组件,这大概是与灰尘。
英文摘要:
The mm-to-cm range of the Spectral Energy Distribution of spiral galaxies remains largely unexplored. Its coverage is required to disentangle the contribution of dust emission, free-free and synchrotron radiation and can provide constraints on dust models, star-formation rates and ISM properties. We present the case for a synergy between NIKA2 observations of nearby spirals and those from planned and current instrumentation at the Sardinia Radio Telescope, and report on a pilot K-band program to search for Anomalous Microwave Emission, an elusive emission component which is presumably related to dust.
