Dwarf Galaxies and the Cosmic Web
Alejandro Benitez-Llambay, Julio F. Navarro, Mario G. Abadi +4
We use a cosmological simulation of the formation of the Local Group of Galaxies to identify a mechanism that enables the removal of baryons from low-mass halos without appealing t…
Galaxy Pairs in the Local Group
Azadeh Fattahi, Julio F. Navarro, Else Starkenburg +2
Current models of galaxy formation predict that galaxy pairs of comparable magnitudes should become increasingly rare with decreasing luminosity. This seems at odds with the relati…
Thin disk kinematics from RAVE and the solar motion
S. Pasetto, E. K. Grebel, T. Zwitter +14
Aims. We study the Milky Way thin disk with the Radial Velocity Experiment (RAVE) survey. We consider the thin and thick disks as different Galactic components and present a techni…
Thick disk kinematics from RAVE and the solar motion
S. Pasetto, E. K. Grebel, T. Zwitter +14
Radial velocity surveys such as the Radial Velocity Experiment (RAVE) provide us with measurements of hundreds of thousands of nearby stars most of which belong to the Galactic thi…
From the CMD of Omega Centauri and (super-)AGB stellar models to a Galactic plane passage gas purging chemical evolution scenario
Falk Herwig, Don A. VandenBerg, Julio F. Navarro +2
[Abbreviated] We have investigated the color-magnitude diagram of Omega Centauri and find that the blue main sequence (bMS) can be reproduced only by models that have a of helium a…
Satellites and Haloes of Dwarf Galaxies
Laura V. Sales, Wenting Wang, Simon D. M. White +1
We study the abundance of satellite galaxies as a function of primary stellar mass using the SDSS/DR7 spectroscopic catalogue. In contrast with previous studies, which focussed mai…
The properties of the local spiral arms from RAVE data: two-dimensional density wave approach
A. Siebert, B. Famaey, J. Binney +19
Using the RAVE survey, we recently brought to light a gradient in the mean galactocentric radial velocity of stars in the extended solar neighbourhood. This gradient likely origina…
The Dynamical State and Mass-Concentration Relation of Galaxy Clusters
Aaron D. Ludlow, Julio F. Navarro, Ming Li +3
We use the Millennium Simulation series to study how the dynamical state of dark matter halos affects the relation between mass and concentration. We find that a large fraction of…
The satellites of the Milky Way - Insights from semi-analytic modelling in a LambdaCDM cosmology
Else Starkenburg, Amina Helmi, Gabriella De Lucia +7
We combine the six high-resolution Aquarius dark matter simulations with a semi-analytic galaxy formation model to investigate the properties of the satellites of Milky Way-like ga…
Exploring the Morphology of RAVE Stellar Spectra
G. Matijevic, T. Zwitter, O. Bienayme +18
The RAdial Velocity Experiment (RAVE) is a medium resolution R~7500 spectroscopic survey of the Milky Way which already obtained over half a million stellar spectra. They present a…
The Missing Massive Satellites of the Milky Way
Jie Wang, Carlos S. Frenk, Julio F. Navarro +2
Recent studies suggest that only three of the twelve brightest satellites of the Milky Way (MW) inhabit dark matter halos with maximum circular velocity, V_max, exceeding 30km/s. T…
The Phoenix Project: the Dark Side of Rich Galaxy Clusters
L. Gao, J. F. Navarro, C. S. Frenk +3
[abridged] We introduce the Phoenix Project, a set of CDM simulations of the dark matter component of nine rich galaxy clusters. Each cluster is simulated at least at two differ…
