Two astronomical papers out in quick succession!!

[michael.h.f.wilkinson]

Two of my PhD students got papers on image analysis of astronomical data accepted and published this month. The first one is a paper on how to detect faint sources optimally, in which we show a program developed at our university works better than the other tools tested, including the stalwart Sextractor. It was published in Astronomy & Astrophysics.

The other is about a new way to analyse (future) SKA data on the Epoch of Re-ionisation, when the first stars started to ionise the neutral hydrogen, causing local dark bubbles in the 21 cm emission (now redshifted to much longer wavelengths). The aim is to determine the distribution of bubble shapes and sizes to determine the nature of the early ionising sources. It was published in the Monthly Notices of the Royal Astronomical Society.

Both are open access papers, so if you're interested, feel free to download them.
