On the ultra-compact dwarf galaxy-nuclear star cluster connection Ultra-compact dwarf galaxies (UCDs) are predominatly found in the cores of nearby galaxy clusters, regions that are dominated by early-type galaxies, among them nucleated dwarf ellipticals. One of the favourite scenarios for the origin of UCDs is that they are isolated nuclei from threshed dwarf galaxies or maybe also from disrupted late-type spiral galaxies that fell into the clusters. In this scenario one would expect to find super... Dr. Michael Hilker |

Can CALIFA tell us something about the cosmic evolution of the star formation rate and stellar mass of the Universe? We investigate the cosmic evolution of the absolute and specific star formation rate (SFR, sSFR) of galaxies as derived from a spatially-resolved study of the stellar populations in a set of nearby galaxies from the CALIFA survey. The results show again the uniqueness of the CALIFA survey to characterize the cosmic evolution of the spatially- resolved SFR and stellar mass of galaxies. Also the success of the fossil record of the stellar... Prof. Rosa González |

Dust belts around Proxima Centauri. First results from a multi-department project at the IAA In this talk I will present the results of an exploratory program we carried out at the ALMA Observatory soon after the discovery of a terrestrial planet candidate in a temperate orbit around Proxima Centauri, the star closest to our Sun. Our ALMA observations reveal the presence of a belt of dust orbiting the star at distances ranging between 1 and 4 au, approximately. This dust might trace a small-scale analog to our solar system's Kuiper Belt... Dr. Guillem Anglada |

Surprising characteristics of the dwarf planet Haumea revealed by a stellar occultation The solar system currently contains 8 planets and 5 dwarf planets. Among the 5 dwarf planets, 4 of them dwell in the transneptunian region, and among the transneptunian dwarf planets, the only one that remained poorly characterized was Haumea. This was because all other dwarf planets had been visited by spacecraft or had produced stellar occultations which allowed us to determine some of their basic physical properties with accuracy. The only... Dr. Jose Luis Ortíz |

GRB 170817A: a peculiar low-luminosity short gamma-ray burst associated with a NS-NS merger gravitational wave signal Short-duration gamma-ray bursts (sGRBs) have long been proposed to be produced in systems involving the coalescence of double neutron stars (NS-NS), and the observations of sGRB afterglows and host galaxies are consistent with such a conjecture. Based on the estimated event rate density derived from previously observed sGRBs at cosmological distances, the chance of detecting a sGRB within a small volume for detectable NS-NS mergers by advanced...

The Supernovae that Accompany Gamma-ray bursts Energetic supernovae have been seen to occur at the same spatial locations as long-duration gamma-ray bursts (GRBs). These so-called gamma-ray burst supernovae (GRB-SNe) are bright and energetic, and their spectra indicate that material within in the supernova outflow moves at tens of thousands of kilometres per second. The first GRB-SN was observed in 1998, with only 50 in the intervening years. Over the past two decades, the physical... Dr. Zach Cano |

Dust evolution in the interstellar medium Dust grains play a crucial role in many physical and chemical processes in the interstellar medium (ISM) and in protoplanetary disks (PPDs). In the ISM, dust properties influence, for example, the formation and temperature of the major molecules in molecular clouds. It is therefore important to characterise the grain size, structure, shape and material composition in all phases of the ISM. Observations of the dust SED and extinction give... Dr. Melanie Köehler |

High-z proto-clusters with the GTC The study of high-z proto-clusters are important for constraining several cosmological parameters. These clusters are hard to find as they do no yet emit the strong X-ray emission typical of the local clusters. These proto-clusters are however found either around strong QSO’s or more often around strong star-forming galaxies. Incidentally, they are also found around strong sub-millimetre galaxies. We have undertaken a search for Lyα sources... Prof. Jose Miguel Rodríguez-Espinosa |

Analogue spacetimes Analogue spacetimes, (as opposed to general relativity spacetimes), arise when applying the mathematics of differential geometry to generic physical systems. As long as the perturbations have finite propagation speed, then the causal structure can be summarized by propagation cones, similar to the light cones of general relativity; thereby defining a conformal structure. Often one can go further and define an analogue Lorentzian metric.... Prof. Matt Visser |

Star formation in nearby early-type galaxies It is well known that there is little star formation activity in early-type galaxies. By cross-matching SDSS DR 7 with RC3 catalog and visually checking the SDSS images, we derive a sample of 583 S0 galaxies with the central spectrophotometric information. In order to separate nebular emission lines from the underlying stellar contribution, we fit the stellar population model to the SDSS spectra of these S0 galaxies. According to the BPT diagram...

Blazars: Order and Disorder Blazars are the most luminous persistent objects in the sky. They emit light across the entire electromagnetic spectrum, from low-energy radio waves to high-energy gamma-rays, and they exhibit variability on timescales that range from years down to minutes. The launch of the Fermi Large Area Telescope (LAT) in 2008 has ushered in a new era of high-energy astrophysics. Prof. Nicholas Macdonald |

Sgr A* and its environment: insights from X-ray observations Almost every massive galaxy has at least one super-massive black hole (SMBH) at its center. Most (>90%) of those SMBHs are quiet. Understanding the accretion of low-luminosity SMBHs represents a very important and fundamental problem in astronomy. Dr. Daniel Wang |

Formación Estelar: ¿podemos acotar el problema? Mientras que la evolución estelar conforma un cuerpo teórico bien estructurado, incluyendo aquí las últimas fases de la misma, la formación estelar está lejos de admitir una formulación teórica predictiva que permita, conociendo las propiedades físicas de la nube molecular, pergeñar las propiedades de la futura población estelar naciente.

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 |

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 |
