A population of highly energetic transient events in the centres of active galaxies

E. Kankare, R. Kotak, S. Mattila +25

Recent all-sky surveys have led to the discovery of new types of transients. These include stars disrupted by the central supermassive black hole, and supernovae that are 10-100 ti…

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…

GALEX Detection of Shock Breakout in Type II-P Supernova PS1-13arp: Implications for the Progenitor Star Wind

S. Gezari, D. O. Jones, N. E. Sanders +23

We present the GALEX detection of a UV burst at the time of explosion of an optically normal Type II-P supernova (PS1-13arp) from the Pan-STARRS1 survey at z=0.1665. The temperatur…

Measuring Quasar Variability with Pan-STARRS1 and SDSS

E. Morganson, W. S. Burgett, K. C. Chambers +10

We measure quasar variability using the Panoramic Survey Telescope and Rapid Response System 1 Survey (Pan-STARRS1 or PS1) and the Sloan Digital Sky Survey (SDSS) and establish a m…

Rapidly-Evolving and Luminous Transients from Pan-STARRS1

M. R. Drout, R. Chornock, A. M. Soderberg +33

In the past decade, several rapidly-evolving transients have been discovered whose timescales and luminosities are not easily explained by traditional supernovae (SN) models. The s…
