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 |

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’)....

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 |

Baryon Acoustic Oscillations and the Expansion History of the Universe The tiny inhomogeneities left over from the inflationary phase seeded the early Universe with primordial density perturbations. The photon-baryon fluid reacted to these perturbations by forming spherical pressure waves known as baryon acoustic oscillations (BAO). These waves propagated through the primordial plasma until the Universe became transparent to radiation, effectively stopping the dragging of the baryons by the photons. This left... A. J.

Understanding the obscuring torus and the nuclear star formation of AGN using GTC/CanariCam observations The fueling of black holes occurring in active galactic nuclei (AGN) is fundamental to the evolution of galaxies. AGN themselves are largely explained in the context of a unified theory, by which a geometrically and optically thick torus of gas and dust obscures the AGN central engine. The torus intercepts a substantial amount of flux from the central engine and and reradiates it in the infrared. There are still many... Almudena Alonso-Herrero |

FORMATION AND EVOLUTION OF COSMIC DUST: THE NANOCOSMOS PROJECT Evolved stars are the factories of cosmic dust. This dust is made of tiny grains that are injected into the interstellar medium and plays a key role in the evolution of astronomical objects from galaxies to the embryos of planets. However, the fundamental processes involved in dust formation and evolution are still a mystery. The aim of the NANOCOSMOS project is to take advantage of the new ... J. Cernicharo, C. Joblin & J.A.

Activity and Evolution of Oort Cloud Comets Comets formed early in the evolution of the solar system while material was accreting to form planets. When proto-planets became large enough, a population of comets was dynamically ejected into the Oort cloud. Comets entering the inner solar system for the first time are called dynamically new comets. These objects have not been heated by the Sun and retain some of the most primordial material available for observation in the solar system... Dr. Dennis Bodewits |

Structural properties of isolated galaxies Distinct components of galaxies are products of internal and environmental processes throughout their lifetimes. Disentangling these processes is an important issue for understanding how galaxies form and evolve. In this context isolated galaxies represent a fruitful population to explore as they should be mainly affected by internal processes (minimal merger/accretion/tidal effects). I will present the structural analysis of a representative... Mirian Fernández Lorenzo |

First results from SDSS IV - MaNGA Large spectroscopic surveys of nearby galaxies (like the Sloan Digital Sky Survey) have shaped our understanding of galaxy evolution. However, to gain insight into the processes shaping the various galactic sub-components, a three-dimensional view (giving access to both spatial and spectral information) is necessary. In recent years, integral field spectroscopy (IFS) surveys of the nearby Universe (Sauron, CALIFA, Sami) are filling in this... Francesco Belfiore |

An ALMA view on the compact obscured nuclei of luminous IR galaxies Until recently, the study of the molecular interstellar medium of galaxies has been mostly focused on a few, relatively abundant, molecular species. Recent attempts at modeling the molecular emission of active galaxies have shown that standard high-density tracers do not provide univocal results and are not able to discriminate between different relevant environments (e.g., star-formation vs AGN). Spectral lines surveys allow us to explore... Francesco Costagliola |

Unveiling the Massive Stars in the Galactic Centre Because of the proximity, the Galactic Centre is an unique lab for studies of the interplay between stars, ISM and super massive black holes in galactic nuclei. The central 200 pc of the Galactic Centre includes 4x10^7 molecular clouds and has a star formation rate of ~0.03 M/yr. Three young, massive and compact star clusters were found and includes around 100 massive stars, which shape the nearby ISM. However, the... Dr. Hui Dong |

The non-thermal universe at the highest energies: TeV gamma-ray astronomy with the MAGIC telescope Some os the most violent processed in the universe present a non-thermal spectrum reaching energies of several tens of TeV. Due to the low fluxes at these energies, we need a technique capable to achieve collection areas of the order of the km^2. This can be reached by the Imaging Atmospheric Cherenkov technique and MAGIC is one of the main detectors for performing ground-based observations using this technique. It consists of two 17m...

The Fingerprint of a Galactic Nucleus: A Multi-Wavelength, High-Angular Resolution, Near Infrared Study of the Centre of the Milky Way The centre of the Milky Way is the only galactic nucleus and the most extreme astrophysical environment that we can examine on scales of milli-parsecs. It is therefore a crucial laboratory for studying galactic nuclei and their role in the context of galaxy evolution. Yet, suitable data that would allow us to examine the stellar component of the Galactic Centre exist for less than 1% of its projected area. This ERC-funded research programme... Dr. Rainer Schödel |
