Sky survey newborn jets distant galaxies
2020/12/11
Astronomers using data from the ongoing VLA Sky Survey have found distant galaxies with supermassive black holes at their cores that have launched powerful, radio-emitting jets of material w...

2014/12/9
We explore the growth of galaxies formed in self-consistent Smoothed Particle Hydrodynamic (SPH) cosmological simulations. In the first Chapter, we examine the temperature history of gas accreted by f...

2011/10/20
We cross match the NVSS and FIRST surveys with three large photometric catalogues of luminous red galaxies (LRGs) to define radio-loud samples. These have median redshifts 0.35, 0.55 and 0.68 and, by ...
Galaxy Zoo: Dust lane early-type galaxies are tracers of recent, gas-rich minor mergers
galaxies: evolution — galaxies: interactions — galaxies: active — galax-ies: elliptical and lenticular
2011/10/17
We present the second of two papers concerning the origin and evolution of local early-type galaxies exhibiting dust features. We use optical and radio data to examine the nature of AGN activity in th...
The ATLAS3D Project-- VIII: Modelling the Formation and Evolution of Fast and Slow Rotator Early-Type Galaxies within $Λ$CDM
galaxies elliptical and lenticular cD – galaxies formation – galaxies evolution – galaxies structure
2011/10/21
We propose a simple model for the origin of fast and slow rotator early-type galaxies (ETG) within the hierarchical $\Lambda$CDM scenario, that is based on the assumption that the mass fraction of ste...

2009/3/19
We investigate the influence of recent advances in research on the
gaseous content of the universe on our knowledge of star formation histories of spiral
galaxies. The discovery of low-redshift popu...
The Fate of Dwarf Galaxies in Clusters and the Origin of Intracluster Stars

2010/9/15
The main goal of this paper is to compare the relative importance of destruction by tides vs. destruction by mergers, in order to assess if tidal destruction of galaxies in clusters is a viable scenar...
