Annotation:

There is strong observational evidence indicating a time lag of order of some 100 Myr between the onset of starburst and AGN activity in galaxies. Dynamical time lags have been invoked to explain this. We extend this approach by introducing a viscous time lag the gas additionally needs to flow through the AGN's accretion disc before it reaches the central black hole. Our calculations reproduce the observed time lags and are in accordance with the observed correlation between black hole mass and stellar velocity dispersion.

My research has focused on locating and measuring star formation and AGN activity in different environments with interferometric and single-dish radio observations. As my first PhD project, I studied the complex interaction between an intermediate redshift (z 0.3) starburst galaxy and a nearby ( 7 kpc separation) QSO using sub-arcsecond VLA observations. I found new evidence for jet-induced star formation activity in the companion galaxy, making the system a strong candidate for this rare, and potentially important process in the early Universe. In my second paper, I investigated the infrared-

Annotation:

The ubiquity of Lyman alpha (Ly alpha) emission in a sample of four bright [O III]- strong star-forming galaxies with redshifts above seven has led to the suggestion that such luminous sources represent a distinct population compared with their fainter, more numerous counterparts. The presence of Lya emission within the reionization era could indicate that these sources created early ionized bubbles due to their unusually strong radiation, possibly because of the presence of active galactic nuclei. To test this hypothesis, we secured long integration spectra with XSHOOTER on the VLT for three

In this Thesis I investigate how, and to which extent, Active Galactic Nuclei (AGN) activity affects the properties of the host-galaxy interstellar medium (ISM). AGN are thought to regulate the host star formation (SF) by injecting large amount of energy in the circumnuclear region, either suppressing or enhancing the formation of new stars. To understand the interplay between AGN and SF multi-wavelength approach is needed, which allows us to trace the different gas components. In the first part of the Thesis, I present the result of a systematic analysis of the X-ray properties of a sample o

>Magister Scientiae - MSc<br>We investigate the link between environment and radiative accretion efficiency using a sample of 8946 radio-loud AGN detected at 1 − 2 GHz in the SDSS Stripe 82 region. We quantify their environments using the surface-density parameter, ƩN, which measures galaxy density based on distances to Nth nearest neighbours. Comparing Ʃ2 and Ʃ5 between AGN and control galaxies, we obtain relative densities that quantify the degree of galaxy clustering around each AGN. Using this, we examine the relation between density and the HERG-LERG dichotomy (accretion-modes) classified

Although the graying of the American society has been well documented, the question as to whether the elderly populace will indeed become a political factor has yet to be determined. Some studies indicate that the elderly will soon develop the consensus needed for political action; other studies counter that the elderly will never be a viable political factor. Among the determinants listed as influencing the political participation equation are standard socioeconomic variables (e.g., race, social status, education, and income). These factors have been studied extensively (Campbell 1960; Key 19

Developmental cortical malformations are a major cause of intractable seizures. Determining the location and timing of susceptibility for epileptiform activity is critical to identifying what mechanisms contribute to epileptogenesis in any model. Using the freeze lesion rat model of polymicrogyria, we have identified, in lesioned cortex, these two aspects of epileptogenesis. Previous studies have demonstrated that epileptiform activity cannot be evoked prior to postnatal day (P) 12, but the malformed cortex is more susceptible to seizures as early as P10.

Physical activity is associated with greater independence in old age. While most research has focused on the frequency, intensity and time spent in activity, inconsistent findings have emerged, possibly due to differences across different types of physical activity. Physical activities differ in terms of their non-metabolic, mental, physical and social demands, however, to date, the effects of these demands on functional independence are unexplored.
