Additional (optional) reading material (if you can not get the full-text papers, use the Athens login, or go through the library):
- 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.
- 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
- Marsh et al's paper weighing the black hole in the low mass X-ray binary A 0620-00
- Schoedel et al's paper on the mass of the black hole in the centre of the Milky Way
- Gilessen et al's paper on the discovery of a gas cloud on its way to SgrA* (see the BBC's news item)
- Silverman et al's paper on IC10 X-1, currently the most massive stellar black hole known
- Shakura & Sunyaev's seminal paper on the structure accretion discs, and a recent discussion on the possible values of "alpha"
- Gänsicke et al's paper on a metal-rich debris disc around a white dwarf, see also this sequence of cartoons
- Tanaka et al's paper on a relativistic Kα emission line from close to the supermassive black hole in MCG-6-30-15
- Marsh & Horne's paper introducing the method of Doppler tomography
