Additional (optional) reading material (if you can not get the full-text papers, use the Warwick Library Proxy):
- An example of infrared imaging using adaptive optics: the expanding shell of a Helium nova.
- The data release (DR9) of the Sloan Digital Sky Survey in the BBC News, a fantastic example of astronomy with state-of-the art technology (multi-object fibre spectrograph, large CCD camera). SDSS is now at DR12.
- Photon-counting in the optical? In principle yes, see First Astronomical Application of a Cryogenic Transition Edge Sensor Spectrophotometer, but is still technologically challenging, and the size of the detector arrays are tiny compared to conventional CCD.
- Direct detection of four planets around the A-star HR8799 as an impressive example of the high-contrast, high spatial resolution that can nowadays be achieved with ground-based telescopes.
- Ransom et al's discovery of A millisecond pulsar in a stellar triple system (see the BBC's new item)
- Van Kerkwijk et al's paper on the detection of Doppler boosting in the light curve of an eclipsing binary
- Gänsicke et al's paper finding the elusive "minimum period spike" in the period distribution of cataclysmic variables
