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…
OzDES Reverberation Mapping Program: CIV lags from six years of data
A. Penton, H. McDougall, T. M. Davis +52
The paper reports 29 successful CIV reverberation time‑lag measurements for high‑redshift active galactic nuclei from the OzDES survey, derives black‑hole masses of 0.8–1.3 billion…
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…
Las Cumbres Observatory Gravitational-Wave Follow-up in the Third and Fourth Observing Runs: Strengths and Weaknesses of a Rapid Response Galaxy Targeted Strategy
Ido Keinan, Iair Arcavi, D. Andrew Howell +34
We present a summary of gravitational-wave (GW) follow-up using the Las Cumbres Observatory global network of telescopes during the third (O3) and fourth (O4) observing runs of the…
Constraints on Dynamical Dark Energy from Multiple Probes in the Full Dark Energy Survey
DES Collaboration, T. M. C. Abbott, M. Adamow +166
We present results on dark energy evolution, assuming a time-dependent equation of state , from growth and geometric probes using the full six-year Dark Energy S…
The Dark Energy Survey Supernova Program: A Reanalysis Of Cosmology Results And Evidence For Evolving Dark Energy With An Updated Type Ia Supernova Calibration
B. Popovic, P. Shah, W. D. Kenworthy +80
We present improved cosmological constraints from a re-analysis of the Dark Energy Survey (DES) 5-year sample of Type Ia supernovae (DES-SN5YR). This re-analysis includes an improv…
