Strong Lensing Cosmology with Population-level Calibrated Neural Ratio Estimation
Sreevani Jarugula, Brian D. Nord, Aleksandra Ćiprijanović +1
Strong gravitational lensing contains key information about cosmic acceleration. Modern and next-generation galaxy imaging surveys are expected to provide high-quality data on $\ma…
The Vera C. Rubin Observatory Data Preview 1
Vera C Rubin Observatory Team, Tatiana Acero Cuellar, Emily Acosta +325
We present Rubin Data Preview 1 DP1, the first data from the NSF DOE Vera C Rubin Observatory, comprising raw and calibrated single epoch images, coadds, difference images, detecti…
BayesEoR: Bayesian 21-cm Power Spectrum Estimation from Interferometric Visibilities
Peter H. Sims, Jacob Burba, Jonathan C. Pober
BayesEoR is a GPU-accelerated, MPI-compatible Python package for estimating the power spectrum of redshifted 21-cm emission from interferometric observations of the Epoch of Reioni…
Hydrogen Epoch of Reionization Array (HERA) Phase II Deployment and Commissioning
Lindsay M. Berkhout, Daniel C. Jacobs, Zuhra Abdurashidova +93
This paper presents the design and deployment of the Hydrogen Epoch of Reionization Array (HERA) phase II system. HERA is designed as a staged experiment targeting 21 cm emission m…
Touching the Sky: The Use of Arduino in Transferring Telescopic Light to Haptic Vibrations
Ruoning Lan, Wanda Diaz Merced
The chaotic nature of outer space and the limitation of visual displays command for much more than visual display of information and for the integration of other sensorial modaliti…
All Sky Modelling Requirements for Bayesian 21 cm Power Spectrum Estimation with BayesEoR
Jacob Burba, Peter H. Sims, Jonathan C. Pober
We present a comprehensive simulation-based study of the BayesEoR code for 21 cm power spectrum recovery when analytically marginalizing over foreground parameters. To account for…
