A Bayesian approach to modelling spectrometer data chromaticity corrected using beam factors -- II. Model priors and posterior odds
The reliable detection of the global 21-cm signal, a key tracer of Cosmic Dawn and the Epoch of Reionization, requires meticulous data modelling and robust statistical frameworks for model validation and comparison. In Paper I of this series, we presented the Beam-Factor-based Chromaticity Correction (BFCC) model for spectrometer data processed using BFCC to suppress instrumentally induced spectral structure. We demonstrated that the BFCC model, with complexity calibrated by Bayes factor-based …

Steve Bannon illustrates the key point we made in ‘The Life of Brian’ - that people makes what they like of religious teaching Matthew 26,52 And then Jesus said unto him ‘Put your sword back into its place, for those who take the sword will perish by the sword” Steve Bannon has rewritten this as “Live by the sword, die by the sword” as though it was a command. I prefer Jesus’s warning of the consequences of violence Only a MAGA Christian could believe that Christ was inciti…

#ndwgoecountdown Meteoriten – Boten aus dem All
Immer wieder bahnen sich Gesteinsbrocken aus dem Weltall ihren Weg auf die Erde. Meteoriten sind interessant für Forschende. Denn die Brocken sind Zeitzeugen der Entstehung des Sonnensystems. Ihre genaue Zusammensetzung kann helfen zu verstehen, wie das Sonnensystem zu dem Ort wurde, den wir heute kennen. Mit echten Meteoriten zu…

JWST/MIRI observations of the young TWA 27 system: hydrocarbon disk chemistry, silicate clouds, evidence for a CPD
The Mid-Infrared Instrument (MIRI) on the James Webb Space Telescope (JWST) enables the characterisation of young self-luminous gas giants at previously inaccessible wavelengths, revealing physical processes in gas, dust, and clouds. We characterise the young planetary system TWA 27 (2M1207) in the mid-infrared (MIR), studying the atmosphere and disk spectra of the M9 brown dwarf TWA 27A and its L6 planetary-mass companion TWA 27b. We obtained data with the MIRI Medium Resolution Spectrometer (…
