11. Shapes of Spacetimes : Collected tales of black holes
Abstract : In theory, the existence of black holes is predicted by general relativity. In reality, there is a general consensus that they exist in space; in particular at the center of many galaxies. The theory of black holes has been around for decades, but there are still interesting questions calling for attention. READ MORE

12. SN 2011dh and the progenitors of Type IIb supernovae
Abstract : Core-collapse supernovae (SNe) are the observed events following the collapse of the core of evolved massive stars. The gravitational energy released creates a powerful shock that disrupts the star and ejects the heated material into the surrounding circumstellar medium. The observed properties depend on the mass lost by the star, e.g. READ MORE

13. Observations of distant supernovae and cosmological implications
Abstract : Type Ia supernovae can be used as distance indicators for probing the expansion history of the Universe. The method has proved to be an efficient tool in cosmology and played a decisive role in the discovery of a yet unknown energy form, dark energy, that drives the accelerated expansion of the Universe.

14. Regional Lung Mechanics and Influence of an Active Diaphragm in Experimental Lung Injury
Abstract : Despite being an essential life-support strategy in severe respiratory failure, mechanical ventilation can, if not optimally set and monitored, lead to injury of the lung parenchyma and diaphragm. These conditions are called ventilator-induced lung injury and ventilator-induced diaphragmatic dysfunction (VIDD), respectively. READ MORE

15. Formation and Evolution of Protoplanetary Discs
Abstract : Protoplanetary discs and the protostars they surround are formed from the gravitational collapse of molecularcloud cores. These discs consist primarily of gas, with a small but important dust component. The roughlymm-sized grains that make up the dust component are the building blocks of planets. READ MORE
