Obscuration beyond the nucleus: infrared quasars can be buried in extreme compact starbursts
Carolina Andonie, David M. Alexander, Claire Greenwell +14
In the standard quasar model, the accretion disk obscuration is due to the canonical dusty torus. Here, we argue that a substantial part of the quasar obscuration can come from the…
The demographics of obscured AGN from X-ray spectroscopy guided by multiwavelength information
Brivael Laloux, Antonis Georgakakis, Carolina Andonie +10
A complete census of Active Galactic Nuclei (AGN) is a prerequisite for understanding the growth of supermassive black holes across cosmic time. A significant challenge toward this…
A panchromatic view of infrared quasars: excess star formation and radio emission in the most heavily obscured systems
Carolina Andonie, David M. Alexander, David Rosario +13
To understand the Active Galactic Nuclei (AGN) phenomenon and their impact on the evolution of galaxies, a complete AGN census is required; however, finding heavily obscured AGNs i…
Towards modelling Ghostly DLAs
Brivael Laloux, Patrick Petitjean, Camille Noûs
We use simple models of the spatial structure of the quasar broad line region (BLR) to investigate the properties of so-called ghostly damped Lyman-α (DLA) systems detected in SDSS…
