The X-ray-Weak Tail of the Quasar Population: Physical Properties and Redshift Evolution of Variability-Selected AGN in eFEDS

P. Arévalo, J. Buchner, M. Salvato +10

(abridged) Aims: To characterize variability-selected AGN candidates within the eROSITA Final Equatorial-Depth Survey (eFEDS), leveraging the synergy between optical variability an…

The NuSTAR Local AGN Distribution Survey (NuLANDS) I: Towards a Truly Representative Column Density Distribution in the Local Universe

Peter G. Boorman, Poshak Gandhi, Johannes Buchner +33

Hard X-ray-selected samples of Active Galactic Nuclei (AGN) provide one of the cleanest views of supermassive black hole accretion, but are biased against objects obscured by Compt…

An uncertainty principle for star formation -- III. The characteristic emission time-scales of star formation rate tracers

Daniel T. Haydon, J. M. Diederik Kruijssen, Mélanie Chevance +4

We recently presented a new statistical method to constrain the physics of star formation and feedback on the cloud scale by reconstructing the underlying evolutionary timeline. Ho…

An uncertainty principle for star formation - II. A new method for characterising the cloud-scale physics of star formation and feedback across cosmic history

J. M. Diederik Kruijssen, Andreas Schruba, Alexander P. S. Hygate +3

The cloud-scale physics of star formation and feedback represent the main uncertainty in galaxy formation studies. Progress is hampered by the limited empirical constraints outside…

LLAMA: Normal star formation efficiencies of molecular gas in the centres of luminous Seyfert galaxies

D. J. Rosario, L. Burtscher, R. I. Davies +23

Using new APEX and JCMT spectroscopy of the CO 2-1 line, we undertake a controlled study of cold molecular gas in moderately luminous Active Galactic Nuclei (AGN) and inactive gala…
