Experimental simulation of the atmospheric ablation of cosmic dust particles: implications for HPLA radar and lidar observations
The inner solar system is full of interplanetary dust particles (IDPs) originating from cometary trails and collisions between asteroids. The entry and evaporation of IDPs in planetary atmospheres is related to a variety of phenomena including formation of mesospheric metal layers and clouds, and stratospheric aerosol chemistry.

The role of magnetic field for stability in relativistic jets
Relativistic jets have been observed or postulated in various astrophysical sources, including active galactic nuclei, microquasars in the galaxy and gamma-ray bursts. There are many unsolved problems related to the relativistic jets, for example, formation & acceelration, collimation, and long-term stability. The most promising mechanisms for producing and accelerating relativistic jets, and maintaining collimated structure of relativistic...

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...

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...

Following the posterior with the ALHAMBRA survey
The probability distribution functions (PDFs) provided by photometric redshift codes such as BPZ are a powerful tool for galaxy evolution studies. Despite of their potential, only a few studies in the literature attempt to use the full PDFs in their analysis and we are still learning how to make the most of them. We present the latests PDF advances from the ALHAMBRA survey, focusing in the estimation of the B-band luminosity function. We...

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...

Dissecting a rare galaxy merger (the Hummingbird) with radio and mm-observations
The Bird is a luminous infrared galaxy product of a triple merger. Previous infrared observations have shown that the ongoing star formation in the least massive of the components (the head) outshines that of the mprimary nuclei (the heart and the body). This clashes with the commonly accepted major merger scenario in which the SF is expected to be higher in central compact regions. Here I will present preliminary results...

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...

Into Darkness: the seek for pulsars in the Galactic Centre
Pulsars are highly-magnetized rotating neutron stars that emit beams of electromagnetic emission. They are unique astronomical laboratories, not only because they are the most magnetized, densest, directly-observable objects in the Universe, but also because they act as extremely precise clocks located all over the Galaxy. The variety of science enabled by pulsars is very broad, from, e.g., limits on the Equation-of-...

The influence of dynamics on airglow and constituents in the terrestrial mesopause region
In the terrestrial atmosphere, the mesopause region (~90 km height) is a transition region between the inviscid lower/middle atmosphere and the geomagnetically forced geospace. It is a region of strong dynamical forcing and where several constituents vary strongly with height one of which is atomic oxygen. Airglow, which is the result of naturally occurring chemiluminescence in the mesopause region involving exothermic reactions associated...

Ubiquitous magnetic flux emergence in the Sun: a fundamental process
The fundamental process of magnetic flux emergence happens continuously and everywhere over the solar surface, hence the ubiquitousness. No matter which spatial (granular, supergranular, active region) and temporal scale we look at buoyant magnetic field coming from the convection zone pierces the photosphere in the form of two opposite polarities and travels upwards through the solar atmosphere. We will describe the general characteristics...

Massive Star Formation at the Puerto Varas Workshop
The recent decades have witnessed major advances in our understanding of the formation of solar-mass stars. However, the formation mechanisms of stars at the extremes  of the mass range, that is, on one hand very massive stars and in the other brown dwarfs, remain poorly understood. I will summarize the main results presented in a recent meeting on massive star formation that took place in Puerto Varas,...

Observing the onset of outflow collimation in a massive protostar: assembling the puzzle
The current paradigm of star formation through accretion disks, and magnetohydrodynamically driven gas ejections, predicts the development of collimated outflows, rather than expansion without any preferential direction. We present radio continuum observations of the massive protostar W75N(B)-VLA 2, showing that it is a thermal, collimated ionized wind and that it has evolved in 18 years from a compact source into an elongated one. This...

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...
