Investigating the Dust Distribution in Galactic Disks with Dustpedia and NiKA2

我们目前正在领导大型国际合作，以利用赫歇尔空间天文台获得的数据。所获得的数据被用于研究附近星系的远红外光谱能量分布，以更多地了解宇宙尘埃的物理性质以及星系随时间演化和变化的方式。卡迪夫仪器集团在赫歇尔的主要仪器之一中占据了领先地位，现在正在领导地面望远镜仪器的发展。其中一台仪器，NIKA2相机，将于2015年秋季部署在IRAM望远镜上。我们提出的项目涉及到该相机独特的成像能力的开发，它被设计为观察1毫米和2毫米的波长。这个项目是专门利用这些数据和我们的赫歇尔数据来尝试和理解以前没有观察到的星际介质中的物理过程。NIKA2数据还将与GMRT新获得的射电连续谱观测相结合。

We are currently leading large international collaborations to exploit dataobtained with the Herschel Space Observatory. The data obtained is beingused to study the far-infrared spectral energy distribution of nearby galaxies tolearn more about the physical properties of cosmic dust and the ways in whichgalaxies have evolved and changed with time. Having taken the leading rolein one of Herschel's primary instruments the Cardiff instrumentation group arenow leading the development of instruments for ground based telescopes.One such instrument, the NIKA2 camera, will be deployed on the IRAMtelescope in autumn 2015. Our proposed project concerns the exploitation ofthe unique imaging capabilities of this camera , which is designed to observeat a wavelength of 1 and 2 mm. The project is to specifically use this dataalong with our Herschel data to try and understand physical processes in theinter-stellar medium not previously observed. The NIKA2 data will also be combined with newly obtained radio continuum observations from the GMRT.
