Gemini NIFS survey of feeding and feedback processes in nearby active galaxies: stellar populations
Prof. Rogério Riffel
Departamento de Astronomia, UFRGS
Resumen:
Active Galactic Nuclei (AGN) characterize a critical phase in galaxy evolution in which its nuclear supermassive black hole (SMBH) is being fed due to gas accretion onto the nuclear region. The AGN feeding and feedback processes are believed to couple the growth of the SMBHs and their host galaxies and are claimed to be responsible for the correlation between the mass of the SMBH and that of the galaxy bulge. The co-evolution scenario and the gas feeding in the inner kiloparsec of galaxies when they are in the active phase imply that the galaxy bulge grows in consonance with the SMBH. Over the last few years, our team has undertaken a major observational effort to understand this co-evolution by recovering the spatially resolved star formation history and studying the stellar kinematics of the inner few tens parsecs of galaxies. To this purpose we are applying an updated version of the STARLIGHT code to Gemini Near-infrared Integral Field Spectrograph (NIFS) data-cubes of nearby Seyfert galaxies. I will discuss these results in this talk.simulations . Unambiguous evidence that ad hoc molecular design enables the electron charge carriers to be freed from both internal and external disorder to ultimately reach band-like transport is provided.

Charge transport in organic semiconductor: From principles to devices.
Prof. Emanuele Orgiu
Université du Québec – Canada
Resumen:
Charge transport in organic semiconductors is notoriously extremely sensitive to the presence of disorder, both internal and external (i.e., related to interactions with the dielectric layer), especially for n-type materials. Internal dynamic disorder stems from large thermal fluctuations both in intermolecular transfer integrals and (molecular) site energies in weakly interacting van der Waals solids and sources transient localization of the charge carriers. The molecular vibrations that drive transient localization typically operate at low-frequency (<a-few-hundred cm−1), which makes it difficult to assess them experimentally. Hitherto, this has prevented the identification of clear molecular design rules to control and reduce dynamic disorder. In addition, the disorder can also be external, being controlled by the gate insulator dielectric properties. During the seminar, I will give a few examples of charge transport in very closely related molecular organic semiconductors using a combination of temperature-dependent inelastic neutron scattering and photoelectron spectroscopy corroborated by electrical measurements, theory, and simulations . Unambiguous evidence that ad hoc molecular design enables the electron charge carriers to be freed from both internal and external disorder to ultimately reach band-like transport is provided.
