Evolutionary properties of the low-luminosity galaxy population in the NGC5044 Group
(Wiley Blackwell Publishing, Inc, 2012-03)
In this third paper of a series we present Johnson-Gunn B, g, V, r, i, z multicolour photometry for 79 objects, including a significant fraction of the faintest galaxies around NGC5044, assessing group membership on the ...
On the formation and stability of fermionic dark matter haloes in a cosmological framework
(Wiley Blackwell Publishing, Inc, 2021-04)
The formation and stability of collisionless self-gravitating systems are long-standing problems, which date back to the work of D. Lynden-Bell on violent relaxation and extends to the issue of virialization of dark matter ...
ROGER: Reconstructing orbits of galaxies in extreme regions using machine learning techniques
(Wiley Blackwell Publishing, Inc, 2020-01)
We present the ROGER (Reconstructing Orbits of Galaxies in Extreme Regions) code, which uses three different machine learning techniques to classify galaxies in, and around, clusters, according to their projected phase-space ...
Hierarchical star formation in nearby galaxies
(EDP Sciences, 2020-10)
Aims. The purpose of this work is to study the properties of the spatial distribution of the young population in three nearby galaxiesin order to better understand the first stages of star formation.Methods. We used ACS/HST ...
The effect of gas accretion on the radial gas metallicity profile of simulated galaxies
(Oxford University Press, 2020-07)
We study the effect of the gas accretion rate (M˙ accr) on the radial gas metallicity profile (RMP) of galaxies using the EAGLE cosmological hydrodynamic simulations, focusing on central galaxies of stellar mass M 109 M ...
Field spheroid-dominated galaxies in a Λ-CDM Universe
(EDP Sciences, 2018-06)
Context. Understanding the formation and evolution of early-type, spheroid-dominated galaxies is an open question within the context of the hierarchical clustering scenario, particularly in low-density environments. Aims. ...
Extending the nearby galaxy heritage with wise: First results from the wise enhanced resolution galaxy atlas
(IOP Publishing, 2013-01)
The Wide-field Infrared Survey Explorer (WISE) mapped the entire sky at mid-infrared wavelengths 3.4 μm, 4.6 μm, 12 μm, and 22 μm. The mission was primarily designed to extract point sources, leaving resolved and extended ...
Chemodynamics of barred galaxies in cosmological simulations: On the Milky Way’s quiescent merger history and in-situ bulge
(Wiley Blackwell Publishing, Inc, 2020-06)
We explore the chemodynamical properties of a sample of barred galaxies in the Auriga magnetohydrodynamical cosmological zoom-in simulations, which form boxy/peanut (b/p) bulges, and compare these to the Milky Way (MW). ...
Tracking the orbit of unresolved subhalos for semi-analytic models
(Wiley Blackwell Publishing, Inc, 2021-10)
We present an updated model for the evolution of the orbits of "orphangalaxies" to be used in the SAG semi-analytical model of galaxy formation andevolution. In cosmological simulations, orphan galaxies are those ...
Scaling relations for globular cluster systems in early-type galaxies
(Wiley Blackwell Publishing, Inc, 2019-07-25)
The formation and growth of globular cluster systems (GCSs) is closely related to the evolutionary processes experienced by their host galaxies. In particular, their radial distributions scale with several properties of ...
