ABSTRACT:   Software is pervasive. In particular, a lot of programs are nowadays produced to be executed in safety critical contexts. It is crucial to certify these programs. There are several methods of certification. By far the most used is testing. But testing can be costly, and more importantly, it only covers a finite number of cases. Formal verification is a vastly different approach: it aims at building a mathematical proof that the program meets its specification, thus covering all possible cases. To increase the level of certification, this proof can even be computer-checked by a...

“DASH: Deep Learning for the Automated Spectral Classification of Supernovae”

Event Date: Jan 27, 2017 in Other Areas, Seminars

ABSTRACT:   We have reached a new era of ‘big data’ in astronomy with surveys now recording an unprecedented number of spectra. In particular, new telescopes such as LSST will soon incease the spectral catalogue by a few orders of magnitude. Moreover, the Australian sector of the Dark Energy Survey (DES) is currently in the process of spectroscopically measuring several thousands of supernovae. To meet this new demand, novel approaches that are able to automate and speed up the classification process of these spectra is essential. To this end, I have developed a software...

Towards understanding the Milky Way with LSST and Gaia

Event Date: Sep 30, 2016 in Other Areas, Seminars

Abstract: I will provide a brief update on the progress of LSST construction, and my work on running end-to-end tests of the nightly image difference processing. I will also describe my scientific focus on the formation of the Milky Way and how the Gaia satellite is giving us the clearest picture of this process to date. With Gaia our raw data on the Milky Way will soon outpace our statistical tools for analyzing these data in a cosmological context, and I will highlight some open questions which could benefit the most from a comprehensive statistical...
