Seminario en IRAM-Granada: Dissecting AGN feedback: the extraordinary multi-phase outflow in the NLSy1 IRAS17020+4544
IRAM-Granada is organising a seminar at their premises in Av. Divina Pastora 7, Local 20, next Wednesday, 29th May at 12:00. The speaker is Dr. Anna Lia Longinotti, from Instituto Nacional de Astrofísica, Óptica y Electrónica (INAOE), Tonanzintla, Puebla (México). She will present a multi-frequency study of the Narrow Lline Seyfert 1 galaxy IRAS17020+4544. Webex/videconference connection can be provided to those interested in participating from external sites.
Dissecting AGN feedback: the extraordinary multi-phase outflow in the NLSy1 IRAS17020+4544
The growing evidence for energy-conserving outflows in powerful and luminous AGN supports the idea that high-velocity X-ray winds launched from the accretion disc evolve after undergoing a shock with the ambient medium, with the ultimate effect to expel enough mass and energy so as to produce the so-called AGN feedback, often invoked in galaxy formation and evolution. This talk will give an overview of AGN Ultra Fast Outflows, how they work, their observational properties and their relation with AGN outflows in other bands, what is their impact on the host galaxies and their role in feedback processes, with focus on recent results obtained from grating spectroscopy of bright sources.
In particular, I will present the case for a multi-phase energy-conserving outflow in the Narrow Line Seyfert 1 Galaxy IRAS17020+4544 spanning from accretion disk to galaxy-scale, which has been targeted by an unprecedented multi-wavelength campaign by the following observatories: XMM-Newton, Chandra-LETG, VLBA, Large Millimeter Telescope, NOEMA and HST/COS.
