[ascl:2305.025] CELEBI: Precision localizations and polarimetric data for fast radio bursts
Scott, D. R.; Cho, H.; Day, C. K.; Deller, A. T.; Glowacki, M.; Gourdji, K.; Bannister, K. W.; Bera, A.; Bhandari, S.; James, C. W.; Shannon, R. M.

The Australian Square Kilometre Array Pathfinder (ASKAP) has been enabled by the Commensal Real-time ASKAP Fast Transients Collaboration (CRAFT) to detect Fast Radio Bursts (FRBs) in real-time and save raw antenna voltages containing FRB detections. CELEBI, the CRAFT Effortless Localization and Enhanced Burst Inspection pipeline, extends CRAFT’s existing software to process ASKAP voltages to produce sub-arcsecond precision localizations and polarimetric data at time resolutions as fine as 3 ns of FRB events. CELEBI uses Nextflow (ascl:2305.024) to link together Bash and Python code to perform software correlation, interferometric imaging, and beamforming, thereby making use of common astronomical software packages.

[ascl:2412.022] ForestFlow: Lyman-alpha cosmology emulator
Chaves-Montero, J.; Cabayol-Garcia, L.; Lokken, M.; Font-Ribera, A.; Aguilar, J.; Ahlen, S.; Bianchi, D.; Brooks, D.; Claybaugh, T.; Cole, S.; de la Macorra, A.; Ferraro, S.; Forero-Romero, J. E.; Gaztañaga, E.; Gontcho, S. Gontcho A; Gutierrez, G.; Honscheid, K.; Kehoe, R.; Kirkby, D.; Kremin, A.; Lambert, A.; Landriau, M.; Manera, M.; Martini, P.; Miquel, R.; Muñoz-Gutiérrez, A.; Niz, G.; Pérez-Ràfols, I.; Rossi, G.; Sanchez, E.; Schubnell, M.; Sprayberry, D.; Tarlé, G.; Weaver, B. A.

ForestFlow emulates the linear biases and small-scale deviation parameters of the 3D flux power spectrum of the Lyman-alpha forest. The parameters are modeled as a function of cosmology – the small-scale amplitude and slope of the linear power spectrum – and the physics of the intergalactic medium.
