Spectral analysis of four 'hypervariable' AGN: a microneedle in the haystack?
A. Bruce, A. Lawrence, C. MacLeod +13
We analyze four extreme active galactic nuclei (AGN) transients to explore the possibility that they are caused by rare, high-amplitude microlensing events. These previously unknow…

LSQ13fn: A type II-Plateau supernova with a possibly low metallicity progenitor that breaks the standardised candle relation
J. Polshaw, R. Kotak, L. Dessart +20
We present optical imaging and spectroscopy of supernova (SN) LSQ13fn, a type II supernova with several hitherto-unseen properties. Although it initially showed strong symmetric sp…

Measuring nickel masses in Type Ia supernovae using cobalt emission in nebular phase spectra
Michael J. Childress, D. John Hillier, Ivo Seitenzahl +34
The light curves of Type Ia supernovae (SNe Ia) are powered by the radioactive decay of Ni to Co at early times, and the decay of Co to Fe from ~60 days…
