Over the next decade, observations conducted with ALMA and the SKA will reveal the process of mass assembly and accretion onto young stars and will be revolutionary for studies of star formation. Here we summarise the capabilities of ALMA and discuss recent results from its early science observations. We then review infrared and radio variability observations of both young low-mass and high-mass stars. A time domain SKA radio continuum survey of star forming regions is then outlined. This survey will produce radio light-curves for hundreds of young sources, providing for the first time a systematic survey of radio variability across the full range of stellar masses. These light-curves will probe the magnetospheric interactions of young binary systems, the origins of outflows, trace episodic accretion on the central sources and potentially constrain the rotation rates of embedded sources.

Synergies between SALT and Herschel, Euclid & the SKA: strong gravitational lensing & galaxy evolution
引力透镜在过去的几年里引起了人们极大的兴趣。由于创新的多波长选择,2000年已知的少数几个强透镜系统现在已经被数百个所取代,并且来自Herschel和其他亚毫米测量的数千个透镜的前景迫在眉睫。欧几里德和平方公里阵列承诺数万甚至数十万。引力透镜是极少数能够绘制暗物质晕分布的探测器之一。透镜还提供了独立的宇宙学参数估计,并使研究星系人口,否则太微弱的详细研究。SALT处于非常有利的位置,可以对Herschel、南极望远镜、Atacama宇宙学望远镜、Euclid和Square Kilometer Array等的前景透镜和背景源的后续观测产生巨大影响。本文回顾了高影响SALT科学的前景和星系演化的许多限制,可能导致。

Stacking of large interferometric data sets in the image- and uv-domain -- a comparative study
我们提出了一种在紫外域叠加无线电干涉数据的新算法。利用模拟的阿塔卡玛大型毫米/亚毫米阵列(ALMA)和卡尔G。Jansky Very Large Array(VLA)Deep Extragalactic Survey(Jansky甚大阵深河外巡天)我们发现,图像和紫外叠加产生类似的结果,但是,紫外叠加通常是更强大的方法。紫外线叠加算法的一个优点是紫外线数据后叠加的可用性,这使得有可能识别和删除有问题的基线。对于深VLA调查,紫外叠加产生的信噪比比图像叠加高20%。此外,我们还研究了一个模拟的VLA数据集,其中1.5”(10-12 kpc在z ~ 1-4)源堆叠的分解源的堆叠。我们发现,紫外线叠加,其中一个模型是直接拟合的vibrium,显着提高了精度和鲁棒性的大小估计。虽然这项工作的科学动机是研究微弱的高z星系,但这里分析的算法也适用于天文学的其他领域。无线电干涉测量数据的叠加预计也将在未来使用LOFAR和平方公里阵列(SKA)等望远镜进行的调查中发挥重要作用。
