ABSTRACT: Pulsars are electromagnetic machines that convert the rotational energy of neutron stars into relativistic magnetically-dominated outflows. How these machines actually operate has remained a puzzle for many years. I will describe the...

Using hydro-cosmological simulations and analytic modeling, we attempt solid predictions for the formation of massive galaxies at high redshift within the LCDM cosmology. The emerging new picture highlights the formation of galaxies at the nodes of...

In the last few decades, advances in observational cosmology have given us a standard model of cosmology. We know the content of the universe to within a few percent. With more ambitious experiments on the way, we hope to move beyond the knowledge...

In the early stages of planet formation dust grains collect to form km-sized planetesimals. Growth beyond a few cms is frustrated by collisional shattering and rapid radial drift of pebbles and rocks. I will present my work on the dynamics of...
