Posterior samples of source galaxies in strong gravitational lenses with score-based priors
Alexandre Adam, Adam Coogan, Nikolay Malkin +4
Inferring accurate posteriors for high-dimensional representations of the brightness of gravitationally-lensed sources is a major challenge, in part due to the difficulties of accu…
Strong-Lensing Source Reconstruction with Denoising Diffusion Restoration Models
Konstantin Karchev, Noemi Anau Montel, Adam Coogan +1
Analysis of galaxy--galaxy strong lensing systems is strongly dependent on any prior assumptions made about the appearance of the source. Here we present a method of imposing a dat…
Disks, spikes, and clouds: distinguishing environmental effects on BBH gravitational waveforms
Philippa S. Cole, Gianfranco Bertone, Adam Coogan +5
Future gravitational wave interferometers such as LISA, Taiji, DECIGO, and TianQin, will enable precision studies of the environment surrounding black holes. In this paper, we stud…
Dimensionally Reduced Waveforms for Spin-Induced Quadrupole Searches
Horng Sheng Chia, Thomas D. P. Edwards, Richard N. George +5
We present highly accurate, dimensionally-reduced gravitational waveforms for binary inspirals whose components have large spin-induced quadrupole moments. The spin-induced quadrup…
One never walks alone: the effect of the perturber population on subhalo measurements in strong gravitational lenses
Adam Coogan, Noemi Anau Montel, Konstantin Karchev +3
Analyses of extended arcs in strong gravitational lensing images to date have constrained the properties of dark matter by measuring the parameters of one or two individual subhalo…
Measuring dark matter spikes around primordial black holes with Einstein Telescope and Cosmic Explorer
Philippa S. Cole, Adam Coogan, Bradley J. Kavanagh +1
Future ground-based gravitational wave observatories will be ideal probes of the environments surrounding black holes with masses . Binary black hole merg…
