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…
