Issues in star and cluster formation The upper mass stellar initial mass function is similar to the mass function of young star clusters. I argue that this is a basic result expected when gravitational focusing on scales much larger than the Jeans length operate. I will also present recent VLBI studies of Orion which yield new distance estimates. Prof. Lee Hartmann |

Young brown dwarfs: exploring the bottom of the Initial Mass Function Brown dwarfs are the objects that bridge the realms of stars and planets, making them important benchmarks for testing star and planet formation theories. In particular, studies of brown dwarfs at young ages are crucial for understanding the mass dependence in the formation and early evolution of stars. Lda. Koraljka Muzic |

Shaking the grounds of unification: are type 1 and type 2 AGN intrinsically different? The simplest standard unified models of Active Galactic Nuclei (AGN), put forward more than 30 years ago, postulate that the diversity of observed properties of AGN can be largely explained as a viewing angle effect resulting in anisotropic nuclear obscuration. A key ingredient of these models is a homogeneous distribution of dust and gas located at tens of parsecs that obscures the AGN nuclear region from certain lines-of-sight (the ‘torus’)....

Massive galaxy clusters: from relaxed to highly substructured Galaxy clusters are important in cosmology to set constraints on various parameters, but they are also intrinsically interesting, since they allow to study many physical processes. The DAFT/FADA survey of 90 clusters in the redshift range 0.4<z<0.9 has allowed us to analyse several aspects of clusters, linked with their formation. We will present here our search for substructuring and its variation with redshift. For subsamples of clusters... Florence Durret |

Spectro-interferometry study of red supergiants Red supergiant stars (RSGs) are cool and massive stars that evolve toward Wolf-Rayet stars and supernovae. They have extended atmospheres and strong stellar winds, which lead to significant mass loss. Currently, the mechanisms that explain the large observed atmospheric extensions are open to debate. The estimation of the fundamental parameters of these stars and their location in the HR diagram are very important for calibrating the... Dr. Belén Arroyo-Torres |

Challenges of the Doppler technique in the presence of stellar noise for the detection of Earth-like exoplanets The Doppler method is still the most efficient one in detecting exoplanets around nearby stars which are amenable for further characterization. In particular, planets as small as the Earth can in principle be detected in hot orbits around sun-like stars (G and K dwarfs), and warm to temperate orbits around M-dwarfs (M<0.5 sun) in orbital periods from a few days to tens of days. Unfortunately, these time-scales are plagued with structured... Dr. Guillem Anglada-Escude |

Following the posterior with the ALHAMBRA survey The probability distribution functions (PDFs) provided by photometric redshift codes such as BPZ are a powerful tool for galaxy evolution studies. Despite of their potential, only a few studies in the literature attempt to use the full PDFs in their analysis and we are still learning how to make the most of them. We present the latests PDF advances from the ALHAMBRA survey, focusing in the estimation of the B-band luminosity function. We... Carlos López-Sanjuan |

High Spatial Resolution 2D Nebular Abundances in Disk Galaxies Galaxies evolve through the changes that face their various components such as the gas, dust, stars, and dark matter. Gas and dust are prime ingredients for the formation of new stars, and thereafter the massive stars newly formed will quickly modify the chemical composition of galaxies whereas low mass stars will take more time to contribute to the interstellar gas enrichment. Beside the stars, other processes occurring during the galaxies... Laurie Rousseau-Nepton |

Dissecting a rare galaxy merger (the Hummingbird) with radio and mm-observations The Bird is a luminous infrared galaxy product of a triple merger. Previous infrared observations have shown that the ongoing star formation in the least massive of the components (the head) outshines that of the mprimary nuclei (the heart and the body). This clashes with the commonly accepted major merger scenario in which the SF is expected to be higher in central compact regions. Here I will present preliminary results...

Baryon Acoustic Oscillations and the Expansion History of the Universe The tiny inhomogeneities left over from the inflationary phase seeded the early Universe with primordial density perturbations. The photon-baryon fluid reacted to these perturbations by forming spherical pressure waves known as baryon acoustic oscillations (BAO). These waves propagated through the primordial plasma until the Universe became transparent to radiation, effectively stopping the dragging of the baryons by the photons. This left... A. J.

Into Darkness: the seek for pulsars in the Galactic Centre Pulsars are highly-magnetized rotating neutron stars that emit beams of electromagnetic emission. They are unique astronomical laboratories, not only because they are the most magnetized, densest, directly-observable objects in the Universe, but also because they act as extremely precise clocks located all over the Galaxy. The variety of science enabled by pulsars is very broad, from, e.g., limits on the Equation-of-... Pablo Torne |

The influence of dynamics on airglow and constituents in the terrestrial mesopause region In the terrestrial atmosphere, the mesopause region (~90 km height) is a transition region between the inviscid lower/middle atmosphere and the geomagnetically forced geospace. It is a region of strong dynamical forcing and where several constituents vary strongly with height one of which is atomic oxygen. Airglow, which is the result of naturally occurring chemiluminescence in the mesopause region involving exothermic reactions associated... Prof. William Ward |

Observing the onset of outflow collimation in a massive protostar: assembling the puzzle The current paradigm of star formation through accretion disks, and magnetohydrodynamically driven gas ejections, predicts the development of collimated outflows, rather than expansion without any preferential direction. We present radio continuum observations of the massive protostar W75N(B)-VLA 2, showing that it is a thermal, collimated ionized wind and that it has evolved in 18 years from a compact source into an elongated one.
