Visitamos un cometa. El éxito de la misión Rosetta Tras recorrer casi seis mil cuatrocientos millones de kilómetros a través del Sistema Solar, la sonda Rosetta (ESA) ha completado varios hitos en la exploración espacial: despertó con éxito tras meses en hibernación, se colocó en órbita en torno al cometa 67P/Churyumov-Gerasimenko y liberó un módulo robótico, Philae, que se posó sobre el núcleo del cometa...

Structural properties of isolated galaxies Distinct components of galaxies are products of internal and environmental processes throughout their lifetimes. Disentangling these processes is an important issue for understanding how galaxies form and evolve. In this context isolated galaxies represent a fruitful population to explore as they should be mainly affected by internal processes (minimal merger/accretion/tidal effects). I will present the structural analysis of a representative... Mirian Fernández Lorenzo |

First results from SDSS IV - MaNGA Large spectroscopic surveys of nearby galaxies (like the Sloan Digital Sky Survey) have shaped our understanding of galaxy evolution. However, to gain insight into the processes shaping the various galactic sub-components, a three-dimensional view (giving access to both spatial and spectral information) is necessary. In recent years, integral field spectroscopy (IFS) surveys of the nearby Universe (Sauron, CALIFA, Sami) are filling in this... Francesco Belfiore |

An ALMA view on the compact obscured nuclei of luminous IR galaxies Until recently, the study of the molecular interstellar medium of galaxies has been mostly focused on a few, relatively abundant, molecular species. Recent attempts at modeling the molecular emission of active galaxies have shown that standard high-density tracers do not provide univocal results and are not able to discriminate between different relevant environments (e.g., star-formation vs AGN). Spectral lines surveys allow us to explore... Francesco Costagliola |

Unveiling the Massive Stars in the Galactic Centre Because of the proximity, the Galactic Centre is an unique lab for studies of the interplay between stars, ISM and super massive black holes in galactic nuclei. The central 200 pc of the Galactic Centre includes 4x10^7 molecular clouds and has a star formation rate of ~0.03 M/yr. Three young, massive and compact star clusters were found and includes around 100 massive stars, which shape the nearby ISM. However, the... Dr. Hui Dong |

La cuna de la vida: cómo se forman las estrellas y los planetas Hace casi veinte años que se descubrió el primer exoplaneta, pero desde mucho antes los astrónomos que estudiamos cómo se forman la estrellas ya teníamos evidencias de que otras estrellas como el Sol podían estar rodeadas de sistemas planetarios. Las estrellas se forman a partir del colapso de nubes enormes de gas y polvo. En este proceso, la estrella acaba rodeada de un disco en rotación a su alrededor. Mayra Osorio |

The non-thermal universe at the highest energies: TeV gamma-ray astronomy with the MAGIC telescope Some os the most violent processed in the universe present a non-thermal spectrum reaching energies of several tens of TeV. Due to the low fluxes at these energies, we need a technique capable to achieve collection areas of the order of the km^2. This can be reached by the Imaging Atmospheric Cherenkov technique and MAGIC is one of the main detectors for performing ground-based observations using this technique. It consists of two 17m...

The Fingerprint of a Galactic Nucleus: A Multi-Wavelength, High-Angular Resolution, Near Infrared Study of the Centre of the Milky Way The centre of the Milky Way is the only galactic nucleus and the most extreme astrophysical environment that we can examine on scales of milli-parsecs. It is therefore a crucial laboratory for studying galactic nuclei and their role in the context of galaxy evolution. Yet, suitable data that would allow us to examine the stellar component of the Galactic Centre exist for less than 1% of its projected area. This ERC-funded research programme... Dr. Rainer Schödel |

'What is the progenitor system of the nearby Type Ia SN 2014J?' Type Ia supernovae (SNe Ia) are the thermonuclear explosive end-products of white dwarfs. SNe Ia are primary cosmological distance indicators and a major contributor to the chemical evolution of galaxies, yet we do not know what makes a SN Ia. There are two basic families of models leading to a SN Ia, the single- degenerate model (SD) and the double-degenerate model (DD). In the SD scenario, a WD... Dr. Miguel Ängel Pérez Torres |

The brief lives of massive stars as witnessed by interferometry Massive stars present the newest and perhaps most challenging opportunity for long baseline interferometry to excel. Large distances require high angular resolution both to study the means of accreting enough mass in a short time and to split new-born multiples into their components for the determination of their fundamental parameters. Dust obscuration of young stellar objects require interferometry in the infrared, while post-... Dr. Christian Hummel |

Remote sensing: survival strategies in the jungle of averaging kernels and covariance matrices Outer space, stars, exoplanets, planets in the solar system, and even the Earth's middle and upper atmosphere have in common that it is inconvenient, expensive, and often technically unfeasible to make in situ measurements there. Remote sensing, e.g., by means of radiance measurements, is a relatively cheap and convenient alternative. The conversion of the measured radiances to the quantities of interest, e.g., temperature and composition... Dr. Thomas von Clarmann |

Inconsistences in the harmonic analysis of time series The power of asteroseismology relies on the ability to infer the stellar structure from the unambiguous frequency identification of the correspoinding pulsation mode. Hence, the use of a Fourier transform is in the basis of asteroseismic studies. Nevertheless, the difficulties with the interpretation of the frequencies found in many stars lead us to reconsider Fourier analysis and the classical methods used to process time series...

Sculpting the Galactic Centre: Astrophysics and fundamental physics with photons and gravitational waves Since 1993 we have known that the Galactic Center (GC) displays a core-like distribution of red giant branch (RGB) stars starting at ~ 1'', which poses a theoretical problem, because the GC should have formed a segregated cusp of old stars. I postulate that the reason for the missing stars in the RGB is closely intertwined with the formation of a formerly existing dense gas disk, an episode that removed the... Dr. Pau Amaro-Seoane |

New findings on the X-ray emission from Wolf-Rayet nebulae We present the most recent results of XMM-Newton and Chandra observations on the only four Wolf-Rayet (WR) nebulae observed to date. Given the limited number of observations and the different morphological and spectral characteristics of these nebulae, it has been difficult to understand the physics behind the plasma emission. Numerical and analytical models can not explain the 'soft' nature and low plasma temperatures (T~106 K)... Jesús A. Toalá |

The Nature of the IR Emission in Low-Luminosity AGN at Parsec Scales The vast majority of AGN belong to the low-luminosity class (LLAGN): they exhibit a low radiation efficiency (L/Ledd < 10^-3) and the absence of the big blue bump in their spectra, a signature of the accretion disk. The study of LLAGN is a complex task due to the contribution of the host galaxy, whose light outshines these faint nuclei. As a consequence, numerical models are usually compared with relatively poorly defined spectral energy... Juan Antonio Fernández Ontiveros |

Quasars and their emission lines as cosmological probes Quasars are the most luminous stable sources in the Universe. They are currently observed out to redshift z ~ 7 when the Universe was less than one tenth of its present age. Since their discovery 50 years ago astronomers have dreamed of using them as standard candles. Unfortunately quasars cover a very large range (8 dex) of luminosity making them far from standard. I briefly review several methods that can potentially exploit quasars... Dr. Paola Marziani |

La nave espacial Rosetta y el cometa 67P viajan juntos hacia el Sol Los responsables de la misión han proyectado el viaje de Rosetta hacia el cometa de tal manera que el encuentro con el cometa 67P se produzca cuando este se sitúe a unos 675 millones de kilómetros del Sol. Entonces, el cometa apenas presentará actividad y su forma se reducirá a una bola compuesta de hielo y, posiblemente, material rocoso, materiales que, se piensa, pueden constituir los restos inmaculados de la formación del Sistema Solar.

Hot potatoes: the compact obscured nuclei of dusty IR galaxies Evidence is now mounting that most of the activity in some luminous infrared galaxies takes place in their compact obscured nuclei (CONs), regions of less than 100~pc in diameter, which harbor large amounts of warm (T$>$100~K) molecular material (N(H$_2$)$>10^{24}$~cm$^{-2}$). The combined effect of warm, shielded gas and intense infrared radiation produce rich molecular spectra, which make these objects unique laboratories to study... Dr. Francesco Costagliola |

Spectroscopy of the short GRB 130603B: The host galaxy and environment of a compact object merger The nature of short duration gamma-ray bursts (GRBs) remains a central problem of modern astrophysics. They are thought to be related to the violent merger of compact objects, such as neutron stars or black holes, which would make them promising sources of gravitational waves. The absence of supernovae signatures clearly indicates that SGRB progenitors differ from their long duration cousins, but constraints to-date arise almost entirely from...

Main-Belt Comets Since the discovery of 133P/Elst-Pizarro in 1996, an object moving in a typical Main Asteroid Belt orbit, but displaying a comet-like tail, nine more of those objects have been identified. They constitute a new class of small Solar System bodies, the ``missing link'' between asteroids and comets. Three of those objects fall into the ``disrupted asteroids'' subgroup, where the activity is suspected to be driven by either a... Dr. Fernando Moreno |

Cosmological Simulations of Galaxy Formation We present a suite of simulated galaxies, that match a wide range of scaling relations over a large mass range at z=0, and follow the evolution of these relations and confront them with observational constraints. We then make connections to "galactic archaeology" by examining the nature of the major structural components of the discs, highlighting that far and near field cosmology can be combined using these types of simulations. We... Dr. Chris Brook |

SN 1993J and M81: a fruitful astrophysical collaboration SN1993J, a powerful radio supernova high in the northern sky, has been monitored with VLBI though its lifetime. The VLBI observations have been phase-referenced to the core of M81. We will highlight the main results obtained: its extremely circular shell-like radio structure has expanded over 15 years in a rather self-similar way; the expansion is wavelength dependent, a result which can be mainly explained by a combination of a varying free-...

Can we solve by solar magneto-seismology one of astrophysics great problems: Coronal heating enigma? The latest satellite and ground-based observations have provided us a wealth of evidence of waves and oscillations present in the solar atmosphere from the low photosphere to the upper corona. Our understanding of the magnetically dominated structures and their dynamics in the solar atmosphere has been considerably enhanced in light of the latest high spatial and temporal resolution observations (e.g. DST/ROSA, IBIS, CoMP, SST/CRISP; SOHO,...

PAH's in Titan's Upper Atmosphere Observations of Titan's atmosphere made with the VIMS instrument on board the Cassini satellite show a strong limb emission around 3.3 µm at high atmospheric altitudes (above 700 km). This emission exhibits the typical spectral signatures of the strong CH4 bands. A detailed analysis of the spectra reveals, however, an additional strong emission centered at 3.28 µm and peaking at about 950 km. We have untangled this spectral... Prof. Manuel López-Puertas |

Hall motions and star escape in galactic dynamics in the Hill approach The motion of a galactic cluster is approximately described by those equations in a co-moving frame, introduced by Hill in the XIXth century. Individual motions can only studied numerically, but for the center of mass interstellar gravitational forces drop out and one is left with a simply system analogous to those considered by Hall for a planar electron in crossed electric and magnetic fields. In both cases, the motion of the COM is... Dr. P. Horvathy |
