Interaction effects on galaxy pairs with Gemini/GMOS- I: electron density
(Wiley, 2014-01)
We present an observational study about the impacts of the interactions on the electron density of HII regions located in seven systems of interacting galaxies. The data consist of long-slit spectra in the range 4400-7300 ...
ALMA [N II] 205 mu m Imaging Spectroscopy of the Interacting Galaxy System BRI 1202-0725 at Redshift 4.7
(IOP PUBLISHING LTD, 2017)
We present the results from Atacama Large Millimeter/submillimeter Array imaging in the [N II] 205 mu m fine-structure line (hereafter [N II]) and the underlying continuum of BRI 1202-0725, an interacting galaxy system at ...
The role of the Galactic bar in the chemical evolution of the Milky Way
(Oxford University PressOxford, 2014)
In the absence of an interaction, central bars might be the most effective mechanism for radial
motions of gas in barred spiral galaxies, which represent two-thirds of disc galaxies. The
dynamical effects induced by bars ...
FINDING FOSSIL GROUPS: OPTICAL IDENTIFICATION AND X-RAY CONFIRMATION
(IOP PUBLISHING LTDBRISTOL, 2012)
We report the discovery of 12 new fossil groups (FGs) of galaxies, systems dominated by a single giant elliptical galaxy and cluster-scale gravitational potential, but lacking the population of bright galaxies typically ...
Interactions, mergers and the fundamental mass relations of galaxies
(EDP Sciences, 2006-12)
We present a study of the effects of mergers and interactions on the mass distribution of galactic systems in hierarchical clustering scenarios using the disc-bulge structural parameters and their dynamical properties ...
Galaxy And Mass Assembly (GAMA): extended intragroup light in a group at z=0.2 from deep Hyper Suprime-Cam images
We present a pilot study to assess the potential of Hyper Suprime-Cam Public Data Release 2 (HSC-PDR2) images for the analysis of extended faint structures within groups of galaxies. We examine the intragroup light (IGL) ...
The effects of mergers on the formation of disc-bulge systems in hierarchical clustering scenarios
(Oxford University Press, 2003-02)
We study the effects of mergers on the structural properties of disc-like systems by using smooth particle hydrodynamical (SPH) numerical simulations in hierarchical clustering scenarios. In order to assess the effects of ...
