We present the prospects for a future joint gamma-ray and radio survey of southern hemisphere sources using the Fermi Large Area Telescope (LAT) and the upcoming Australian Square Kilometre Array Pathfinder (ASKAP) radio telescope. ASKAP is a next generation radio telescope designed to perform surveys at GHz frequencies at a much higher survey speed than previous radio telescopes, and is scheduled to start engineering observations in 2011. The survey capabilities of both Fermi LAT and ASKAP are described, and the planned science surveys for ASKAP are summarized. We give some expected details of the Variable and Slow Transient (VAST) survey using ASKAP, which will search for transients on timescales from 5 seconds to years. Some observational properties of faint and transient sources seen at gamma-ray and radio wavelengths are summarized, and prospects and strategies for using ASKAP survey data for LAT source counterpart identification are summarized.

Prospects for Discovering Pulsars in Future Continuum Surveys Using Variance Imaging
在Dai等人（2016）中，我们开发了一种形式主义，用于从包含时间和频率信息的标准干涉无线电图像计算方差图像。方差成像与未来的无线电连续调查，使我们能够识别无线电脉冲星，并作为一个补充，传统的脉冲星搜索是最敏感的严格的周期性信号。在这里，我们进行模拟来预测我们可以在未来的连续调查中使用方差成像发现的卫星数量。我们表明，澳大利亚SKA探路者（ASKAP）的宇宙进化图（EMU）调查可以发现$\sim30$正常的恒星和$\sim40$毫秒恒星（MSP）超过和超过今天已知的数量，同样的，一个全天空连续调查与SKA-MID可以发现$\sim140$正常的恒星和$\sim110$ MSP与此技术。EMU和SKA-MID的方差成像将检测具有大占空比的双星，因此是在相对论双星系统中寻找MSP和双星的潜在工具。与目前在南半球银河系高纬度地区进行的脉冲星调查相比，EMU和SKA-MID的方差成像将更加灵敏，并将能够探测色散测量值在$\sim10$和100 cm $^{-3}$ pc之间的脉冲星。
