An outflow powers the optical rise of the nearby, fast-evolving tidal disruption event AT2019qiz
M. Nicholl, T. Wevers, S. R. Oates +42
At 66 Mpc, AT2019qiz is the closest optical tidal disruption event (TDE) to date, with a luminosity intermediate between the bulk of the population and iPTF16fnl. Its proximity all…
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…
Slow blue nuclear hypervariables in PanSTARRS-1
A. Lawrence, A. G. Bruce, C. MacLeod +23
We discuss 76 large amplitude transients (Delta-m>1.5) occurring in the nuclei of galaxies, nearly all with no previously known Active Galactic Nucleus (AGN). They have been discov…
Selection of Burst-like Transients and Stochastic Variables Using Multi-Band Image Differencing in the Pan-STARRS1 Medium-Deep Survey
S. Kumar, S. Gezari, S. Heinis +24
We present a novel method for the light-curve characterization of Pan-STARRS1 Medium Deep Survey (PS1 MDS) extragalactic sources into stochastic variables (SV) and burst-like (BL)…
X-ray Fluctuation Power Spectral Densities of Seyfert 1 Galaxies
A. Markowitz, R. Edelson, S. Vaughan +11
By combining complementary monitoring observations spanning long, medium and short time scales, we have constructed power spectral densities (PSDs) of six Seyfert~1 galaxies. These…
