Characterisation of an Isolated Galaxy Sample: Astrophysical Implications In order to understand the evolution of galaxies, it is necessary to have a reference sample where the effects of the environment are minimised and quantified. Recent advances in large redshift galaxy surveys, such as the Sloan Digital Sky Survey (SDSS), allow to reach a 3-dimensional picture of the environment. In the first two parts of this talk, I will present a revision of the isolation degree and a study of the 3-dimensional... Mamen Argudo Fernández Sala de Juntas del Nuevo Edificio (IAA-CSIC) |

AGN feedback and accretion in Perseus A The Perseus Cluster is known as a famous observational example of (radio-mode) AGN feedback driven by the radio jet of the central galaxy Perseus A (NGC 1275, 3C 84). The feedback process is evident from observations of the intra-cluster medium showing X-ray bubbles filled with radio plasma. The radio jet generating these bubbles is powered by accretion onto the supermassive black hole in Perseus A. In this talk, I will present our results... Dr. Julia Scharwächter |

The Martian ionosphere The ionospheres of the planets (those regions with a significant fraction of free electrons and ions) provide interesting clues about the interaction of the solar radiation and the solar energetic particles with the planetary atmospheres.They can also be used to gain information about the density and temperature of the neutral upper atmospheres, a region that in the Martian case has traditionally eluded observation. In this talk I will sketch... Dr. Francisco González Galindo |

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 |

Here I present results on a the very particular class of born-again planetary nebulae, those whose central star has experienced a helium shell flash during the lifetime of the planetary nebula. The interaction of the fast stellar wind of the central star with hydrogen-poor material ejected during the born-again episode provides a unique case to study... Dr. M. Guerrero |

How is it possible that a stationary component appears to be composed by subcomponents moving at superluminal speeds? The AGNs are a special class of galaxies that show an unusual amount of emission.

Probing Galaxy-Scale Halos and Large-Scale Structure with Weak Gravitational Lensing The presence of dark matter in the Universe is well-established and contributes significantly to structures ranging from galaxies to superclusters. However, the details of the connection between luminous galaxies and the dark matter halos in which they reside are not particularly well-characterised. Weak gravitational lensing is the only direct probe that can measure the total mass profile associated with galaxies over a wide range of radii... Dr. Ami Choi |

The X-ray emission from PNe comes in two flavors: compact sources in the vicinity of the central star and extended sources that fill the nebular cavities generated during the PN formation process. The latter variety, called hot bubbles, are chemically-enriched with helium shell burning products (C, O, and Ne... Dr. Rodolfo Montez |
