We study the properties of satellites in the environment of massive star-forming galaxies at z ∼ 1.8 in the COSMOS field, using a sample of 215 galaxies on the main sequence of star formation with an average mass of ∼1011 M . At z > 1.5, these galaxies typically trace halos of mass 10 M . We use optical-near-infrared photometry to estimate stellar masses and star formation rates (SFR) of centra...

Centriolar satellites are proteinaceous granules that are often clustered around the centrosome. Although centriolar satellites have been implicated in protein trafficking in relation to the centrosome and cilium, the details of their function and composition remain unknown. FOP (FGFR1 Oncogene Partner) is a known centrosome protein with homology to the centriolar satellite proteins FOR20 and O...

We study the evolution of dark matter satellites orbiting inside more massive haloes using semi-analytical tools coupled with high-resolution N-Body simulations. We select initial satellite sizes, masses, orbital energies, and eccentricities as predicted by hierarchical models of structure formation. Both the satellite (of initial mass Ms,0) and the main halo (of mass Mh) are described by a Nav...
