Stellar Tidal Streams in Nearby Galaxies as Dark Matter Probes Mergers and tidal interactions between massive galaxies and their dwarf satellites are a fundamental prediction of the Lambda-Cold Dark Matter cosmology. These events are thought to influence galaxy evolution throughout cosmic history and to provide important observational diagnostics of nonlinear structure formation. Thin stellar streams in the Milky Way and Andromeda galaxies are spectacular evidence for satellite disruption at the... Dr. David Martinez-Delgado |

Nonlinear dynamics of space and astrophysical plasmas Solar atmosphere and solar wind provide a unique laboratory for understanding the nonlinear dynamics of space and astrophysical plasmas. A quantitative analysis of the reconnection condition and the degree of intermittency reveals that rope–rope magnetic reconnection is the most likely site for genesis of interplanetary intermittency turbulence in this event. The dynamic pressure pulse resulting from this reconnection triggers the onset of a... Prof. Abraham Chian |

What we (don't) know about the trans-Neptunian objects The first trans-Neptunian object was discovered in 1930 and we waited over 60 years to discover the second one. The discovery of Albion (a.k.a. 1992QB1) enticed the minor bodies community to characterize the new population, called collectively as trans-Neptunian objects (TNOs). Today we know the existence of over 2,000 objects and counting. Nevertheless, it seems that we have reached our technological limitation in terms of observational studies...

El puzzle de Arp299. Agujeros negros que devoran estrellas En enero de 2005 se detectaba, en el núcleo de la galaxia en proceso de fusión Arp 299-B, un brillante destello que se consideró una explosión supernova. Sin embargo, diez años de observaciones en distintas longitudes de onda han permitido presenciar cómo la región luminosa se alargaba y expandía, y concluir que se trata de un chorro de material expulsado por el agujero negro supermasivo central de la galaxia tras desgarrar una estrella.

The planetary nebula HuBi 1, a rebel with a cause Planetary nebulae, the descendants of low- and intermediate-mass stars, have characteristic onion-like ionization structure, with the highest ionization species closer to the central star. This is true for all planetary nebulae, but HuBi 1, which shows an inverted ionization inner shell. There is a reason for this oddity, a peculiar stellar evolution of its central star, which makes HuBi 1 the missing link of the population of cool C-rich... Dr. Martin Guerrero |

Optical spectroscopy of local type-1 AGN LINERs The Balmer emission originated in the broad line region (BLR) of active galactic nuclei (AGNs) could be either weak and difficult to detect, or even absent, for low luminosity AGNs, as low ionization nuclear emission-line regions (LINERs). This makes LINERs challenging to fit in the AGN unification scheme. Moreover, a long debate can be found in the literature proposing different ionization sources at the origin of optical emission lines and no... Dr. Sara Cazzoli |

The peculiar case of the active galactic nuclei in PBC J2333.9-2343 Under unification schemes, active galactic nuclei (AGN) can be explained by orientation effects. However, some sources show properties at different frequencies that led to incongruent classifications and cannot be explained by such unification scheme. This is the case of PBC J2333.9-2343; its optical spectrum is of a type 2 AGN but its X-ray spectrum does not show signs of absorption, and in the radio it has many features typical of a blazar but...

Lightning – from Its Base to Space Lightning has been studied for centuries with surprisingly meager progress since the early breakthroughs of Franklin. There are numerous reasons for this lack of progress: lightning is complex, it is very energetic with large peak power - hard for in-situ probes to survive, it is spatially and temporally sparse – hard to place a sensor in an optimal location. However, modern technological advances and innovations have led to new remote... Prof. Hugh Christian |

The LIGO and Virgo gravitational-wave observatories detected the first compact binary inspiral produced by two neutron stars, which was followed about two seconds later by a short GRB, labelled GRB 170817A, detected by the GBM instrument on Fermi. The detection by all three GW observatories allowed the error region to be... Dr. David Alexander Kann |

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 |

Fighting in Maya ruins: Data Engineering, Data Science, computation clusters and the trans-neptunian search tool IAA is sitting under a gold mine of data, achieved in past observing campaigns, that will be increased with the data coming from next instrumentation. A tool that can exploit the wealth beneath our feet is the Engineering and Data Science (EDS). This lecture will introduces the EDS and its application on preliminary analysis on a concrete astronomical problem: the search of trans-neptunian objects. Two of the tools used in this analysis will... Dr. Rafael Morales |

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 |

High resolution radio imaging of nearby star-forming galaxies: on the way to SKA The Square Kilometer Array (SKA) will be a key instrument in the study of our local Universe. In particular, by virtue of its high sensitivity (both to point sources and diffuse low surface brightness emission), angular resolution and the frequency ranges covered, the SKA will undertake a very wide range of astrophysical research in the field of nearby galaxies. By surveying nearby galaxies of all types with microJy sensitivity and sub-arcsecond... Prof. Antxon Alberdi |

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 European VLBI Network (EVN) and user cases to improve your science The European VLBI Network (EVN) is a network of radio telescopes located primarily in Europe and Asia, with additional antennas in South Africa and Puerto Rico. The combination of such extended network of telescopes provides an extremely high angular resolution (down to milliarcsecond scales). In addition to that, and given its unparalleled sensitivity on this type of observations, the EVN becomes a genuine instrument to observe an enormous... Dr. Benito Marcote |

H2O. Agua El agua, H2O, es la matriz de la vida. Al mismo tiempo una molécula sencilla y una substancia muy especial con propiedades extraordinarias y universales, que inextricablemente permea la estructura social, ecológica, biológica y geológica de la Tierra (¿y en cuántos otros exoplanetas?). Haremos un breve recorrido por algunas de las propiedades de la molécula, de la substancia, y de su inmanente presencia. Enrique Pérez Jiménez |

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 |
