Euclid preparation. XXV. The Euclid Morphology Challenge -- Towards model-fitting photometry for billions of galaxies
Euclid Collaboration, E. Merlin, M. Castellano +218
The ESA Euclid mission will provide high-quality imaging for about 1.5 billion galaxies. A software pipeline to automatically process and analyse such a huge amount of data in real…
Spatiotemporal dynamics of ultrarelativistic beam-plasma instabilities
P. San Miguel Claveria, X. Davoine, J. R. Peterson +28
An electron or electron-positron beam streaming through a plasma is notoriously prone to micro-instabilities. For a dilute ultrarelativistic infinite beam, the dominant instability…
The LSST DESC Data Challenge 1: Generation and Analysis of Synthetic Images for Next Generation Surveys
F. Javier Sánchez, Chris W. Walter, Humna Awan +23
Data Challenge 1 (DC1) is the first synthetic dataset produced by the Rubin Observatory Legacy Survey of Space and Time (LSST) Dark Energy Science Collaboration (DESC). DC1 is desi…
Deblending and Classifying Astronomical Sources with Mask R-CNN Deep Learning
Colin J. Burke, Patrick D. Aleo, Yu-Ching Chen +4
We apply a new deep learning technique to detect, classify, and deblend sources in multi-band astronomical images. We train and evaluate the performance of an artificial neural net…
PhoSim-NIRCam: Photon-by-photon image simulations of the James Webb Space Telescope's Near-Infrared Camera
Colin J. Burke, John R. Peterson, Eiichi Egami +3
Recent instrumentation projects have allocated resources to develop codes for simulating astronomical images. Novel physics-based models are essential for understanding telescope,…
Unveiling the Rich and Diverse Universe of Subsecond Astrophysics through LSST Star Trails
David Thomas, Steven M. Kahn, Federica B. Bianco +9
We present a unique method that allows the LSST to scan the sky for stellar variability on short timescales. The operational component of the strategy requires LSST to take star tr…
