Physical and statistical properties of High Frequency Peaked blazars In the class of active galactic nuclei (AGNs), blazars are the most extreme objects, with their relativistic jets closely aligned to our line-of-sight. The emission of blazars is mostly non-thermal, spanning the entire electromagnetic spectrum, and is often linearly polarized providing us with important insights on the magnetic field structure. An emerging radio-loud AGN population is represented by high synchrotron peaked (HSP) blazars,... Dr. Lico |

Stellar activity blurring our insight into the properties of exoplanets Stellar activity can provide important information regarding the structure, evolution, and the atmosphere of the stars, as well as their magnetic filed and mechanisms that generate them. On the other hand stellar activity introduces severe astrophysical noise in the collected data in the quest for what might be called Earth 2.0. In this talk, I will present main obstacles and difficulties which stellar activity poses on the detection and... Dr. Mahmoudreza Oshagh |

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 |

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 |

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 |

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 |

The large abundance discrepancy phenomenon in planetary nebulae The discrepancy between chemical abundances computed using optical recombination lines (ORLs) and collisionally excited lines (CELs) is a major unresolved problem in nebular astrophysics, with significant implications for the determination of chemical abundances throughout the Universe. In planetary nebulae (PNe), a common explanation of this discrepancy is that two different gas phases coexist: a hot component with standard metallicity, and a... Dr. Jorge García Rojas |

Galaxias activas: unas tanto y otras tan poco Muchas galaxias del universo, incluida nuestra propia Vía Láctea, contienen en sus centros agujeros negros supermasivos (de entre unos pocos millones hasta miles de millones de veces la masa del sol). Pero en solo una pequeña fracción de esas galaxias, las llamadas “galaxias activas”, se activan en sus núcleos una serie de mecanismos que pueden llegar a ser muy violentos. Isabel Márquez |

Detection of gravitational waves from space: the LISA mission The idea of detecting gravitational waves from space has been under consideration for more than 25 years. In 2012, the advisory bodies of ESA decided that the next-but-one "large mission", L3, will be devoted to this. Launch is scheduled for 2034. In 2015, the Director of Science of ESA appointed an external committee, with Michael Perryman as chair, to advise on the technical feasibility of the LISA mission, and the technology development...

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...

Supermassive Black Holes: Impact on Galaxy Formation and Evolution Supermassive black holes, weighing between millions to billions times the mass of the Sun, are believed to power quasars and other energetic activity in the centers of galaxies. With the help of advanced telescopes from the ground and in space, operating across the electromagnetic spectrum, astronomers have now discovered that supermassive black holes not only exist, but that they are very common and play a critical role in the formation and...

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 |

The impact of environment and confusion of the observed HI galaxy population The HI galaxy mass function represents a fundamental component of our understanding of the gas content of galaxies. How its form varies throughout the local Universe and as a function of redshift is key to developing a complete picture of galaxy evolution. We use the ALFALFA 70% catalogue, the largest uniform catalogue of extragalactic HI sources to date, to explore the environmental dependence of the HI mass function based on the projected...

Molecular gas and dust in low-metallicity starbursts Metal-poor, star-forming, dwarf galaxies play a fundamental role in galaxy formation and evolution, and according to LambdaCDM models may be the building blocks of most of the galaxies in the universe today. Although the interstellar medium (ISM) in such galaxies was thought to be virtually dust-free, over the last decade, observations have shown that dust can be an important constituent of even a low-metallicity ISM. However, the molecular... Dr. Leslie Hunt |

Cold plasma and magnetic reconnection at the magnetopause boundary layer Magnetic reconnection is a fundamental plasma process that permits the exchange of energy and mass between colliding plasmas, e.g., between the Solar Wind and the Earth's magnetosphere. Several studies have reported the presence of cold plasma of ionospheric origin at the magnetospheric side of the magnetopause boundary layer. As a result, the particle distribution functions involved in reconnection are far from equilibrium, exhibiting a cold... Dr. Sergio Toledo Redondo |

Living on the Edge: Superthin Galaxies and the Cosmic UV Background Superthin galaxies are bulgeless, late-type spiral galaxies seen edge-on. HI synthesis observations probe the kinematic structure of their interstellar medium. Observations of these isolated, quiescent galaxies have reached column densities as low as few x 1018 atoms . cm-2 . The simple structure of the superthins makes them ideal cosmological laboratories (Uson and Matthews, Astron. J. 125, 2455, 2003). I shall present the results of high-... Prof. Juan Usón |

Asteroid surfaces: irradiation and VIS-IR micro-spectroscopy in the laboratory Primitive extraterrestrial materials, such as meteorites and dust collected by sample return missions, are characterized by a large compositional heterogeneity at different scales. This heterogeneity has been observed in the laboratory by different techniques. Among these, micro-IR spectroscopy has the advantage of being totally non-destructive and allowing direct comparison with astronomical observations. With the development of Focal Plan...

Novae as Lithium factories in the Milky Way The abundance of Lithium observed in very young stellar populations is ~4 times larger than the primordial one estimated by recent Planck measurements. Since Lithium is easily destroyed in stellar interiors, the search for astrophysical sources responsible for of the observed Lithium over-abundance was a mystery for decades. In this seminar I'll discuss the recent detection of Lithium in the spectra of two slow novae, V1369 Cen and V5668 Sgr,... Dr. Luca Izzo |

Witnessing the birth of a planetary nebula Planetary nebulae are one of the last stages of evolution of stars like our Sun. The beginning of photoionization, giving rise to a new planetary nebula, will certainly produce dramatic changes in the object, but this instant is difficult to observe, since it will only take a few decades. During of a long-time study of water masers in post-AGB stars and planetary nebulae, we identified an object (IRAS 15103-5754) in which we believe... Dr. Jose Francisco Gómez |

Multiwavelength analysis of PBC J2333.9-2343 Nuclear activity as is observed in active galactic nuclei (AGN) might be a phase occurring in all galaxies, and this activity could be recurrent. A perfect laboratory to test these scenarios are the giant radio galaxies, since their emission can be as old as 10⁷-10⁸ years. In the present work we focus on the nucleus of PBC J2333.9-2343, which called our attention because it is a giant radio galaxy that shows different and incompatible... Dr. Lorena Hernández García |

The CaII triplet in Quasars: from the accretion disk to the star formation Active galactic nuclei (AGN) show a great diversity of optical and UV emission line properties. Dynamical and physical models should be built accordingly. The presence of strong FeII emission suggested the existence of a region shielded from high energy photons, where the low ionization lines are emitted. Mary Loli Martínez Aldama |
