Communicating astrobiology and the search for life elsewhere: speculations and promises of a developing scientific field in newspapers, press releases and papers
Danilo Albergaria, Pedro Russo, Ionica Smeets +2
This study examines the communication of astrobiology and the Search for Life Elsewhere (SLE) in academic papers, press releases, and news articles over three decades. Through a qu…
The Gaia Astrometric Catalogue and Secular Aberration Drift in Proper Motions
Anthony G. A. Brown, Ulrich Bastian, Sergei Klioner
A recent paper demonstrated the existence of a secular aberration drift term in stellar proper motions that arises when transforming an astrometric catalogue defined for an observe…
The X-ray Integral Field Unit at the end of the Athena reformulation phase
Philippe Peille, Didier Barret, Edoardo Cucchetti +279
The Athena mission entered a redefinition phase in July 2022, driven by the imperative to reduce the mission cost at completion for the European Space Agency below an acceptable ta…
PACMAN: A pipeline to reduce and analyze Hubble Wide Field Camera 3 IR Grism data
Sebastian Zieba, Laura Kreidberg
Here we present PACMAN, an end-to-end pipeline developed to reduce and analyze HST/WFC3 data. The pipeline includes both spectral extraction and light curve fitting. The foundation…
Gaia Data Release 3: External calibration of BP/RP low-resolution spectroscopic data
P. Montegriffo, F. De Angeli, R. Andrae +46
Context. Gaia Data Release 3 contains astrometry and photometry results for about 1.8 billion sources based on observations collected by the European Space Agency (ESA) Gaia satell…
Bayesian error propagation for neural-net based parameter inference
Daniela Grandón, Elena Sellentin
Neural nets have become popular to accelerate parameter inferences, especially for the upcoming generation of galaxy surveys in cosmology. As neural nets are approximative by natur…
