Title: Near field cosmology and the local group of Galaxies
Abstract: Near field cosmology aims at exploiting the high-quality astrophysical
observations of the local Universe for cosmological pourposes.
In recent years, observations Local Group (LG) of galaxies (e.g. relative to
abundance and anisotropy of substructure), have been used to claim
inconsistencies within the Lambda Cold Dark Matter (LCDM) standard model of
cosmology. However, the comparison between random-phase N-body simulations and

The Difference Between Short and Long GRB
GRBs may appear either longer or shorter than their intrinsic duration at the central engine. The various effects that create these illusions are reviewed. It is argued that short GRB are typically seen from a larger off-axis viewing angle than long GRB.

Kinematics of massive star forming disks at z~1-2: outflows, rotation curves and baryon content
I will discuss recent results of the SINS and KMOS-3D spectroscopy surveys of massive star forming galaxies ~10 Gyr ago, obtained on the ESO-VLT. In particular I will focus on the properties of disk and nuclear outflows and the baryon and dark matter content .
