The origin of the Broad Line Region (BLR) in active galaxies remains unknown. It seems to be related to the underlying accretion disk but an efficient mechanism is required to rise the material from the disk surface without giving too strong signatures of the outflow in the case of the low ionization lines. We discuss in detail two proposed mechanisms: (i) radiation pressure acting on dust in the disk atmosphere creating a failed wind (ii) the gravitational instability of the underlying disk. We compare the predicted location of the inner radius of the BLR in those two scenarios with the observed position obtained from the reverberation studies of several active galaxies. The failed dusty outflow model well represents the observational data while the predictions of the self-gravitational instability are not consistent with observations. The issue remains why actually we do not see any imprints of the underlying disk instability in the BLR properties.

“…This can significantly affect the measured broadline lag if the BLR has a characteristic radius on the order of light-days. The variable optical continuum has also been shown to have smoother features and smaller amplitudes than its UV counterpart (e.g., Peterson et al 1991;Dietrich et al 1993Dietrich et al , 1998Stirpe et al 1994;Santos-Lleó et al 1997;Shappee et al 2014;Fausnaugh et al 2016). These differences between the UV and optical continua suggest that the optical continuum is not fully interchangeable with the ionizing source for determining reverberation lags.…”

We present the results of an optical spectroscopic monitoring program targeting NGC 5548 as part of a larger multiwavelength reverberation mapping campaign. The campaign spanned 6 months and achieved an almost daily cadence with observations from five ground-based telescopes. The Hβ and He II λ4686 broad emission-line light curves lag that of the 5100Å optical continuum by , respectively. The Hβ lag relative to the 1158Å ultraviolet continuum light curve measured by the Hubble Space Telescope is ∼50% longer than that measured against the optical continuum, and the lag difference is consistent with the observed lag between the optical and ultraviolet continua. This suggests that the characteristic radius of the broad-line region is ∼50% larger than the value inferred from optical data alone. We also measured velocity-resolved emission-line lags for Hβ and found a complex velocity-lag structure with shorter lags in the line wings, indicative of a broadline region dominated by Keplerian motion. The responses of both the Hβ and He II emission lines to the driving continuum changed significantly halfway through the campaign, a phenomenon also observed for C IV, Lyα, He II (+O III]), and Si IV(+O IV]) during the same monitoring period. Finally, given the optical luminosity of NGC 5548 during our campaign, the measured Hβ lag is a factor of five shorter than the expected value implied by the R BLR -L AGN relation based on the past behavior of NGC 5548.

“…Para SANTOS (1990), há duas formas, geralmente concomitantes, de lidar com a aposentadoria: crise -pela recusa em aceitar a condição de aposentado, especialmente devido à imagem estigmatizada vinculada à inatividade que tal condição confere; liberdade -sentimento resultante da busca pelo prazer em atividades de lazer e concretização de planos anteriormente não possíveis de se realizarem pelo compromisso/obrigação de trabalhar.…”

RESUMOEste estudo busca uma discussão sobre como o trabalho influencia a construção da identidade e quais suas consequências frente à aposentadoria. Os sujeitos desta pesquisa consistiram em servidoras aposentadas de uma agência pública de fomento à ciência e Tecnologia, localizada no Distrito Federal. Especificamente, buscou-se caracterizar o contexto de vida atual nas dimensões das relações sociais, das atividades ora desenvolvidas e suporte familiar; descrever as vivências de prazer e sofrimento e investigar os mecanismos utilizados para mediar o sofrimento. Foram realizadas duas entrevistas semiestruturadas coletivas que foram analisadas por meio da Análise de Núcleo de Sentido. Os resultados, com base nos depoimentos colhidos nas entrevistas, evidenciam o quanto o trabalho implica diretamente nas diversas formas de inserção social dos sujeitos e mostra a dificuldade e o sofrimento que emergem da perda da identidade social com a ausência do trabalho. Conclui-se que o sofrimento advindo da aposentadoria está fortemente relacionado à ausência de um projeto de preparação para a aposentadoria. PALAVRAS-CHAVE: prazer, políticas públicas, sofrimento. IDENTITY, WORK AND RETIREMENT: STUDY OF RETIRED EMPLOYEES OF A PUBLIC FOUNDATIONABSTRACT This study aims a discussion about how work influences the construction of identity and what its consequences forward to retirement. The subjects are servants retired from a public agency promoting science and technology, located in the Federal District. Specifically, it sought to characterize the context of current life in the dimensions of social relations, now developed activities and family support; describes the experiences of pleasure and pain and investigates the mechanisms used to mediate suffering. Two collective semi-structured interviews were conducted that were analyzed by the ANS. The results, based on interviews conducted; show how much work involves directly the various forms of social integration of subjects and shows the difficulty and suffering that emerge from the loss of social identity with
