Illuminating the Physics of Cosmic Origin and Evolution: A UK Space Frontiers 2035 White Paper
Florian Beutler, Eva-Maria Mueller, Seshadri Nadathur +61
Understanding the Universe's origins and evolution remains one of the most fundamental challenges in modern cosmology. This white paper explores three key science priorities in thi…
COSMOS-Web: Comprehensive Data Reduction for Wide-Area JWST NIRCam Imaging
Maximilien Franco, Caitlin M. Casey, Anton M. Koekemoer +37
We present the data reduction methodology used for the COSMOS-Web survey JWST NIRCam data. Covering 0.54 deg^2 with four broadband filters (F115W, F150W, F277W, F444W) and a total…
On Soft Clustering For Correlation Estimators
Edward Berman, Sneh Pandya, Jacqueline McCleary +14
Properly estimating correlations between objects at different spatial scales necessitates distance calculations. For this reason, most widely adopted packages fo…
SpecPT (Spectroscopy Pre-trained Transformer) Model for Extragalactic Spectroscopy: I. Architecture and Automated Redshift Measurement
Rohan Pattnaik, Jeyhan S. Kartaltepe, Clive Binu
We introduce the Spectroscopy Pre-trained Transformer (SpecPT), a transformer-based model designed to analyze spectroscopic data, with applications in spectrum reconstruction and r…
Efficient PSF Modeling with ShOpt.jl: A PSF Benchmarking Study with JWST NIRCam Imaging
Edward Berman, Jacqueline McCleary, Anton M. Koekemoer +13
With their high angular resolutions of 30--100 mas, large fields of view, and complex optical systems, imagers on next-generation optical/near-infrared space observatories, such as…
CEERS Epoch 1 NIRCam Imaging: Reduction Methods and Simulations Enabling Early JWST Science Results
Micaela B. Bagley, Steven L. Finkelstein, Anton M. Koekemoer +34
We present the data release and data reduction process for the Epoch 1 NIRCam observations for the Cosmic Evolution Early Release Science Survey (CEERS). These data consist of NIRC…
