Dynamics and properties of gas at the Center of the Galaxy In the central parsec of the Milky Way Galaxy the environment of the super-massive black hole (SMBH) presents a complicated composition that includes a very young star cluster mixed with qby tidally stretched clouds of ionized gas (the Minispiral). The Galactic Center's inner few tens of arcseconds have been observed at high resolution with Keck for 20 years, with the primary goal of monitoring stars orbiting the SMBH. This unique baseline of... Dr. Anna Ciurlo |

Bringing science to kids and general public at the Observatoire de la Côte d'Azur It is important to transmit the science developed in a research institution to the public. This transmission helps to increase the scientific culture of the general public, and also can help to awake scientific vocations in the kids. During this talk I will present several actions carried out at the Observatoire de la Côte d'Azur (Nice, France), to bring astronomy to the school children and also to the general public. I will talk about the... Dr. Olga Suarez |

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 |

Hydrodynamical models of planetary nebulae with [WC] central stars High-resolution, long-slit spectroscopic observations of two planetary nebulae, M1-32 and M3-15 are presented. The observations were obtained with the 2.1-m telescope at the OAN- SPM, and MES spectrograph. M1-32 shows wide wings on the base of its emission lines, M3-15 has two very faint high-velocity knots. To model M1-32 and M3-15 we built a 3D model consisting in a jet interacting with an equatorially concentrated slow wind, emulating the... Jackeline Rechy Garcia |

Simetrías de las partículas y las interacciones: ¿el Higgs como escapatoria? La Estructura Unificada de las Partículas Elementales y sus Interacciones ha encontrado dos grandes obstrucciones matemáticas. Una escapatoria a ambos problemas, no resueltos, la proporciona el Mecanismo de Higgs-Kibble, que supone la introducción de la misteriosa partícula Higgs (conocida como partícula de dios, no con la acepción religiosa, sino en el sentido de maldita) en el escenario del Modelo Estándar de Partículas.

The Early History of Gamma-ray Bursts The discovery of Gamma-Ray Bursts (GRBs), and the subsequent realization that they are the result of the largest and most distant explosions in the Universe, represents one of the most surprising and fundamental discoveries in astronomy in the past century. Several space-borne and ground-based breakthrough observations in GRBs that led to this realization occurred during the 1990’s. This discovery resulted in the award of the 2011 Shaw Prize...

Gravitational waves: the "other light" from Cosmos First direct detections of gravitational waves were reported in the first half of 2016. These observations represented: i) a confirmation of a fundamental prediction of General Relativity dynamics, and ii) a demonstration of the existence of binaries of stellar-mass black holes capable of merging in a timescale shorter than the Universe's age. This talk will review the basic elements needed to frame the two statements above. The presentation... Prof. J.L. Jaramillo |

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...

Recovering information beyond the power spectrum of large-scale structure Future galaxy surveys of the large-scale structure in the Universe will provide a wealth of new data and make it possible to use higher-order statistics beyond the power spectrum, such as the bispectrum (or 3-point correlation function), to constrain galaxy clustering, the standard LCDM cosmology, and many of its possible extensions. However, it may be possible and preferable to use recently devised alternative statistics, such as the line... Dr. Joyce Byun |
