Testing disc reprocessing models for AGN optical variability by comparison of X-ray and optical power spectra of NGC 4395

Max Beard, Ian McHardy, Keith Horne +11

It is generally thought that AGN optical variability is produced, at least in part, by reprocessing of central X-rays by a surrounding accretion disc, resulting in wavelength-depen…

JWST detection of heavy neutron capture elements in a compact object merger

A. Levan, B. P. Gompertz, O. S. Salafia +80

The mergers of binary compact objects such as neutron stars and black holes are of central interest to several areas of astrophysics, including as the progenitors of gamma-ray burs…

Localised thermonuclear bursts from accreting magnetic white dwarfs

S. Scaringi, P. J. Groot, C. Knigge +16

Nova explosions are caused by global thermonuclear runaways triggered in the surface layers of accreting white dwarfs. It has been predicted that localised thermonuclear bursts on…

On the multi-wavelength variability of Mrk 110: Two components acting at different timescales

F. M. Vincentelli, I. McHardy, E. M. Cackett +17

We present the first intensive continuum reverberation mapping study of the high accretion rate Seyfert galaxy Mrk 110. The source was monitored almost daily for more than 200 days…

Periodicities in the K2 lightcurve of HP Librae

Siddhant Solanki, Thomas Kupfer, Omer Blaes +2

We analyse Kepler/K2 lightcurve data of the AM CVn system HP Librae. We detect with confidence four photometric periodicities in the system: the orbital frequency, both positive an…

Multimessenger science opportunities with mHz gravitational waves

John Baker, Zoltán Haiman, Elena Maria Rossi +32

LISA will open the mHz band of gravitational waves (GWs) to the astronomy community. The strong gravity which powers the variety of GW sources in this band is also crucial in a num…
