The Radius-Luminosity Relationship for Active Galactic Nuclei with Hierarchical Bayesian Reverberation Mapping

Hugh McDougall, Tamara M. Davis, Benjamin J. S. Pope +6

Reverberation mapping of active galactic nuclei uses the time taken for variability to travel through the system as a measure of system size, with this size being used to inform es…

The Cosmic Radio Dipole and Observer Effects in SKA all-sky surveys

D. Bertacca, L. Böhme, B. Bottazzi Baldi +13

The Square Kilometre Array (SKA) will observe our Universe on the largest scales and so enable the study of fundamental assumptions in cosmology, such as cosmic homogeneity and iso…

Harnessing stellar kinematics to constrain dark energy with the double-source-plane gravitational lens SDSS J0946+1006

Daniel J. Ballard, Wolfgang J. R. Enzi, Thomas E. Collett +6

SDSS J0946+1006 is an attractive target for measuring cosmological parameters through lens modelling. It is the best-studied galaxy-scale strong gravitational lens with multiple so…

AGN Reverberation Mapping with LITMUS: Fundamental Limits on lag Recovery Rates

Hugh McDougall, Tamara M. Davis, Benjamin J. S. Pope +4

Reverberation mapping of active galactic nuclei provides one of the most direct probes of the geometry and kinematics of the broad-line region by measuring time delays between cont…

Simulation-based tension quantification of the cosmic dipole

Mali Land-Strykowski, Harry T. J. Bevins, Oliver T. Oayda +1

The cosmic dipole measured in surveys of cosmologically distant sources consistently exceeds the expectation derived from the cosmic microwave background, posing a significant chal…

Microlensing of Microlensing: Effects of Random Stars on the Double-Source-Plane Gravitational Lens

Nada Salama, Daniel J. Ballard, Huimin Qu +2

Microlensing, the influence of stars within a galactic gravitational lens, has emerged as a powerful probe of compact mass and, through differential magnification, sub-parsec scale…

The Ellis and Baldwin test of the Cosmic Dipole: Exploring the impact of multiple flux density cuts

Vasudev Mittal, Geraint F. Lewis

The cosmic dipole tension - the discrepancy between the Cosmic Microwave Background kinematic dipole and the matter dipole inferred from all-sky surveys poses a significant challen…

Multi-band Reconstruction of Sixteen Gravitational Lens Systems using PISCO data

Huimin Qu, Daniel J. Ballard, Geraint F. Lewis +12

Next-generation surveys such as the Euclid survey, the Legacy Survey of Space and Time (LSST), and the China Space Station Telescope (CSST) survey are expected to discover ~10^5 ga…

OzDES Reverberation Mapping of Active Galactic Nuclei: Final Data Release, Black-Hole Mass Results, & Scaling Relations

H. McDougall, T. M. Davis, Z. Yu +53

Over the last decade, the Australian Dark Energy (OzDES) collaboration has used Reverberation Mapping to measure the masses of high redshift supermassive black holes. Here we prese…

OzDES Reverberation Mapping Program: CIV lags from six years of data

A. Penton, H. McDougall, T. M. Davis +52

We present 29 successfully recovered CIV time lags in Active Galactic Nuclei from the complete Dark Energy Survey Reverberation Mapping campaign. The AGN in this sample span a reds…

Cosmic dipole tensions: confronting the cosmic microwave background with infrared and radio populations of cosmological sources

Mali Land-Strykowski, Geraint F. Lewis, Tara Murphy

The cosmic dipole measured in surveys of cosmologically distant sources is generally found to be in disagreement with the kinematic expectation of the Cosmic Microwave Background (…

Constraining Cosmology with Double-source-plane Strong Gravitational Lenses from the AGEL Survey

Duncan J. Bowden, Nandini Sahu, Anowar J. Shajib +17

Double-source-plane strong gravitational lenses (DSPLs), with two sources at different redshifts, are independent cosmological probes of the dark energy equation of state parameter…

The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics

Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533

The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…

Dark Energy Survey Year 1 Results: Cross-Correlation Redshifts - Methods and Systematics Characterization

M. Gatti, P. Vielzeuf, C. Davis +104

We use numerical simulations to characterize the performance of a clustering-based method to calibrate photometric redshift biases. In particular, we cross-correlate the weak lensi…

A Study of Quasar Selection in the Dark Energy Survey Supernova fields

S. S. Tie, P. Martini, D. Mudd +75

We present a study of quasar selection using the DES supernova fields. We used a quasar catalog from an overlapping portion of the SDSS Stripe 82 region to quantify the completenes…

Gravitational Microlensing as a probe of the Electron Scattering Region in Q2237+0305

D. J. Kedziora, H. Garsden, G. F. Lewis

Recent observations have provided strong evidence for the presence of an Electron Scattering Region (ESR) within the central regions of AGNs. This is responsible for reprocessing e…
