– Carlo Contaldi (Imperial) – ”Parity violations in polarization”
–Daniela Saadeh (UCL) – ”How isotropic is the Universe?”

Update: talks now available at links below.
The next London Cosmology Discussion Meeting will be held next week at 1400 on Thursday 29th October at the Royal Astronomical Society.
There is no overall theme, but we have two theory talks related to field theory for inflation and dark energy and two talks focusing more on methods for and analysis of data.
The talks and the speakers will be the following:
14:00 – 14:25: Soft limits in multifield inflation — David Mulryne (QMUL)
14:25 – 14:50: Effective field theory in cosmology — Raquel Ribeiro (QMUL)
14:50 – 15:15: Discussion
15:15 – 15:45: *** Tea break ***
15:45 – 16:10: Transient astronomy and machine learning for cosmology in the era of LSST — Michelle Lochner (UCL)
16:10 – 16:35: Bahamas: Bayesian reanalysis of SNe data — Hik Shariff (Imperial)
16:35 – 17:00: Discussion
