The Case for Space Environmentalism
A. Lawrence, M. L. Rawls, M. Jah +8
The shell bound by the Karman line at a height of 80 to 100km above the Earth's surface, and Geosynchronous Orbit, at 36,000km, is defined as the orbital space surrounding the Eart…
Systematic light curve modelling of TDEs: statistical differences between the spectroscopic classes
Matt Nicholl, Daniel Lanning, Paige Ramsden +4
With the sample of observed tidal disruption events (TDEs) now reaching several tens, distinct spectroscopic classes have emerged: TDEs with only hydrogen lines (TDE-H), only heliu…
Spectropolarimetry of NGC3783 and Mrk509: Evidence for powerful nuclear winds in Seyfert 1 Galaxies
P. Lira, M. Kishimoto, R. W. Goosmann +6
We present results from high signal-to-noise optical spectropolarimetric observations of the Seyfert 1 galaxies NGC783 and Mrk509 in the 3500-7000 A range. We find complex structur…
The Tidal Disruption Event AT 2018hyz I: Double-peaked emission lines and a flat Balmer decrement
P. Short, M. Nicholl, A. Lawrence +28
We present results from spectroscopic observations of AT 2018hyz, a transient discovered by the ASAS-SN survey at an absolute magnitude of mag, in the nucleus of a…
Long-term NIR Variability in the UKIDSS Ultra Deep Survey: a new probe of AGN activity at high redshift
E. Elmer, O. Almaini, M. Merrifield +5
We present the first attempt to select AGN using long-term NIR variability. By analysing the K-band light curves of all the galaxies in the UKIDSS Ultra Deep Survey, the deepest NI…
Through Andromeda and Beyond: AGN Optical Transient 'Sharov21' Revisited
A. Bruce, A. Lawrence, D. McLeod +1
We revisit a notable AGN known as `Sharov21', seen to undergo a dramatic outburst in 1992, brightening by a factor of thirty over a period of approximately one year. A simple micro…
