IRyAGN

This is the web page of the IRyAGN group. A group devoted to the study of active galactic nuclei (AGN) using multiwavelength information. This group begun in 2017, when we start to gather together to pursue different group projects. Since then we have published several papers together.

The AGN residing at the center of some galaxies are known to have a complex structure of clouds. These clouds are composed by gas and dust, being the latter confined to the outer radii due to the strong radiation field of the AGN. The importance of this component is key due to its role on the obscuration of the inner accretion disk and the high velocity clouds, and, therefore, responsible for some of the diversity of AGN classes observed. Despite the enormous amount of effort put into studying it, little is known on the subject. The main difficulty on the study of this obscuring material is its physical extension (smaller than a dozen of parsecs), which prevents to spatially resolve it with the current state-of-the- art instruments. This group collect all kind of evidences to give the most complete picture of dust and obscuration around AGN and its connection to the gas, using the most advanced models and first-class current and future instruments.
