Euclid Quick Data Release (Q1): The impact of AGN emission on SED-derived physical properties
Euclid Collaboration, B. Laloux, A. Bongiorno +309
The Euclid Quick Data Release (Q1) is a powerful dataset to study active galactic nuclei (AGN) and their host galaxies. Deriving their physical properties through multi-component s…
Characterizing the roles of transitory obscured phases and inner torus in shaping the fractions of obscured AGN at cosmic noon
Alba V. Alonso-Tetilla, Francesco Shankar, Fabio Fontanot +11
The origin of obscuration in Active Galactic Nuclei (AGN) is still a matter of contention. It is unclear whether obscured AGN are primarily due to line-of-sight effects, a transito…
An obscured quasar census with the 4MOST IR AGN survey: design, predicted properties, and scientific goals
Carolina Andonie, David M. Alexander, Claire Greenwell +11
We present the 4MOST IR AGN survey, the first large-scale optical spectroscopic survey characterizing mid-infrared (MIR) selected obscured active galactic nuclei (AGN). The survey…
How to set up your first machine learning project in astronomy
Johannes Buchner, Sotiria Fotopoulou
Large, freely available, well-maintained data sets have made astronomy a popular playground for machine learning projects. Nevertheless, robust insights gained to both machine lear…
