Secondary evolution of galaxies investigated by N-body simulations [PDF]
, 2008 In the ΛCDM cosmology, merging is one of the most important physical processes that drives the formation and evolution of galaxies. In the present work, we use N-body techniques to investigate some of currently open issues related to the formation and ...

The Problem of Psychonomic Harmony
Philosophy and Phenomenological Research, EarlyView.ABSTRACT The problem of nomological harmony is the problem of explaining why the laws of nature match or apply to the states of the universe in a way that results in temporal evolution. The problem of psychophysical harmony is the problem of explaining why phenomenal states are paired with physical states and other phenomenal states in surprisingly ...

Gas Outflows in Radio Galaxies [PDF]
Symposium - International Astronomical Union, 2004 We present a summary of our recent results on gas outflows in radio galaxies. Fast outflows (up to 2000 km s−1) have been detected both in ionized and neutral gas. The latter is particularly surprising as it shows that, despite the extremely energetic phenomena occurring near an AGN, some of the outflowing gas remains, or becomes again, neutral.

The evolution of radio galaxies
, 2010 Radio galaxies with extended lobes are believed to interact strongly with their environment. In this thesis, I investigate the evolution of radio galaxies with different properties and track them through the cosmological ages.In Chapters 2 and 3, I ...

The Astrophysical JournalWe present a detailed study of radio-detected dwarf galaxies ( M _⋆ ≲ 3 × 10 ^9 M _⊙ ) to characterize extreme star formation and search for (variable) radio active galactic nuclei (AGNs). Our sample comes from A. E.

On Our Cosmic (In)significance
Ratio, EarlyView.ABSTRACT This article discusses three interpretations of cosmic significance, all of which reveal something important about the notion of significance. Along the way, it proposes a unified view of significance by combining elements of each of the views.

, 2003 Recent results on the radio emission from galaxy clusters are reviewed, with emphasis both on the radio galaxies and on the diffuse radio emission from the intracluster medium. We show that the formation of the tailed morphology in cluster radio galaxies is due to the effect of the cluster gaseous environment and of its large scale motions in merging ...

EMU/GAMA: Radio detected galaxies are more obscured than optically selected galaxies [PDF]
We demonstrate the importance of radio selection in probing heavily obscured galaxy populations. We combine Evolutionary Map of the Universe (EMU) Early Science data in the Galaxy and Mass Assembly (GAMA) G23 field with the GAMA data, providing optical ...

The Astronomical JournalThe Fanaroff–Riley radio galaxies exhibit the most extensive radio emissions derived from the active nuclei of galaxies. They morphologically differ from the highly compact and bright radio galaxies observed as gigahertz peaked spectrum and compact steep
