    Fossil group origins. VIII. RX J075243.6+455653 a transitionary fossil group
    Context. It is thought that fossil systems are relics of structure formation in the primitive Universe. They are galaxy aggregations that have assembled their...

    Fossil group origins. X. Velocity segregation in fossil systems
    Aims: We aim to study how the velocity segregation and the radial profile of the velocity dispersion depend on the prominence of the brightest cluster galaxies...
  • Publication
    Fossil group origins. XI. The dependence of galaxy orbits on the magnitude gap
    Aims: We aim to study how the orbits of galaxies in clusters depend on the prominence of the corresponding central galaxies. Methods: We divided our data set of...

    Fossil group origins. XII. The large-scale environment around fossil systems
    Aims: We analyse the large-scale structure out to 100 Mpc around a sample of 16 confirmed fossil systems using spectroscopic information from the Sloan Digital...

    Fossil group origins. XIII. A paradigm shift: Fossil groups as isolated structures rather than relics of the ancient Universe
    Aims: In this work we study the large-scale structure around a sample of non-fossil systems and compare the results with earlier findings for a sample of...

    Fossil groups origins. I. RX J105453.3+552102 a very massive and relaxed system at z ~ 0.5
    Context. The most accepted scenario for the origin of fossil groups is that they are galaxy associations in which the merging rate was fast and efficient. These...

    Four new massive pulsating white dwarfs including an ultramassive DAV
    We report the discovery of four massive (M > 0.8 M⊙) ZZ Ceti white dwarfs, including an ultramassive 1.16 M⊙ star. We obtained ground-based, time series...

    Four sub-Jovian-mass planets detected by high-cadence microlensing surveys
    Aims: With the aim of finding short-term planetary signals, we investigated the data collected from current high-cadence microlensing surveys. Methods: From...
  • Publication
    Four winters of photometry with ASTEP South at Dome C, Antarctica
    Context. Dome C in Antarctica is a promising site for photometric observations thanks to the continuous night during the Antarctic winter and favorable weather...
