MeerKAT observations of the spiral galaxy NGC 2997 in the S band. Detection of high dynamo modes
A. Damas-Segovia, R. Beck, S. A. Mao +18
We seek to exploit the expanded observational range of the MeerKAT radio telescope with the new S-band receivers (2.0-2.8 GHz). To showcase its enhanced capabilities, we conducted…
H I Properties of Field Galaxies at -0.6: Insights into Declining Cosmic Star Formation
David DePalma, Neeraj Gupta, Hsiao-Wen Chen +18
We report statistically significant detection of H I 21-cm emission from intermediate-redshift (-0.6) galaxies. By leveraging multi-sightline galaxy survey data from t…
Evaluation of Provenance Serialisations for Astronomical Provenance
Michael A. C. Johnson, Marcus Paradies, Hans-Rainer Klöckner +5
Provenance data from astronomical pipelines are instrumental in establishing trust and reproducibility in the data processing and products. In addition, astronomers can query their…
Pipeline Provenance for Analysis, Evaluation, Trust or Reproducibility
Michael A. C. Johnson, Hans-Rainer Klöckner, Albina Muzafarova +5
Data volumes and rates of research infrastructures will continue to increase in the upcoming years and impact how we interact with their final data products. Little of the processe…
