A possible dwarf galaxy satellite-of-satellite problem in ?CDM

Dark matter clusters on all scales, and it is therefore expected that even substructure should host its own substructure. Using the Extragalactic Distance Database, we searched for dwarf-galaxy satellites of dwarf galaxies, that is, satellite-of-satellite ...

The Pristine survey - XV. A CHIT ESPaDOnS view on the Milky Way halo and disc populations

Pascale Jablonka, Willem Suter, Carmela Lardo, Romain Ely Roland Lucchesi

We present a one-dimensional, local thermodynamic equilibrium homogeneous analysis of 132 stars observed at high resolution with ESPaDOnS. This represents the largest sample observed at high resolution (R similar to 40 000) from the Pristine survey. This s ...

Study of the Sextans dwarf spheroidal galaxy from the DART Ca ii triplet survey star

Pascale Jablonka

We use Very Large Telescope (VLT)/Fibre Large Array Multi Element Spectrograph (FLAMES) intermediate-resolution (R similar to 6500) spectra of individual red giant branch stars in the near-infrared Ca ii triplet (CaT) region to investigate the wide-area me ...

Relating basic properties of bright early-type dwarf galaxies to their location in Abell 901/902

We present a study of the population of bright early-type dwarf galaxies in the multiple-cluster system Abell 901/902. We use data from the STAGES survey and COMBO-17 to investigate the relation between the color and structural properties of the dwarfs and ...

Membership and binarity of solar-type dwarfs in the nearby open cluster Alpha Persei (Mel 20)

Jean-Claude Mermilliod

Context. The Alpha Persei open cluster (Melotte 20) is one of the nearby clusters (d < 500 pc) for which a long-term systematic radial-velocity monitoring of the solar-type stars has not been published so far. ...
