My research interests focus on the searches and characterization of substellar companions, i.e., brown dwarfs and extrasolar planets to stars, particularly using direct imaging techniques. Currently I am carrying out a project aiming to identify such companions using the VISTA Hemishpere Survey data.

My research in plan:
1.- Improve our gas-grain model to include more realistic processes and try to establish Monte Cario gas-grain model for the purpose to study microscopic grain surface processes.
2.- Design observations to verify the chemical effects caused by turbulent dust grain motions.
3.- Use our chemical model to explain the chemical abundances in star-formation regions.
4.- Carry out MHD simulation study of turbulent grain dynamics with co-authors (important for grain chemistry).
5.- The isotopic chemistry of D, 13C, 15N and 18O.

Do the properties of stars forming in dense, massive star-forming regions differ from those in nearby low-mass star forming regions? I aim to put constraints on the differences in their properties using multi-wavelength observations of star-forming regions in the Milky Way, and extra-Galactic systems.

My research focuses on the formation of massive stars. Since their formation appears to be intimately linked to the one of the molecular clouds in which they form, I study the dynamical connections between the parent molecular cloud and the individual objects (massive dense cores). My second field of interest concerns the ignition of the collimated jets in T-Tauri and Herbig objects, by magneto-centrifugal scenarios, in order to get a deeper understanding of how this ubiquitous phenomenon is generated. To accomplish this, I carry out single dish and interferometric observations at optical, IR and submillimeter wavelengths.

I’m interested in extrasolar planets orbiting cool stars. I use the radial velocity technique that requires data from high-resolution spectrographs (e.g. HARPS-ESO). Cool stars are benchmark objects to discover Earth-mass planets orbiting in temperate orbits. Besides detecting and characterising potentially habitable exoplanets, I’m interested in the stellar physics of the host stars. In particular, I search for the first observational confirmation of a seismic signal in M-dwarf stars. Stellar pulsations are common for most spectral types but they have not been detected in M dwarfs. Among the implications, their discovery will trigger the asteroseismology theory allowing a better knowledge of the star parameters and thus constraining the parameters of the posible hosted exoplanets. I’m also part of the CARMENES consortium, a high-resolution optical-NIR spectrograph settled at the CAHA observatory aimed at monitoring 300 M-dwarf stars of the northern hemisphere to discover new exo-worlds.

I am a Chilean astronomer born and raised in the beautiful city of Valparaíso. When I was studying engineering at UTFSM, I discovered astronomy through astrophysics.
I moved to Universidad de Chile to complete my Bachelor and Master in Science with major in Astronomy, working mainly on type II supernovae (SNe) and their capability of delivering cosmological distances.
I obtained my PhD in 2013 from the Technical University Munich. The thesis was developed at the Max-Planck-Institute for Extraterrestrial Physics, where I studied SNe that have been found in association with gamma-ray bursts (GRBs).
Currently, I work at the Universidad Andrés Bello within the MAS SN group on optical and near-infrared spectroscopy and photometry of stripped-envelope SNe.
Since a couple of years I have also been analyzing data from SNe and their associated GRBs in search of correlations.

I am highly specialized in black hole accretion and planet formation in the field of Astrophysics. I use optical to infrared spectroscopy to study stellar mass black holes, and various observational tools to study protoplanetary discs. I am an expert on modeling and sophisticated simulations of planets interacting with their disks. I obtained my PhD at Oxford University on Inflow and Outflow in Microquasars (stellar mass black holes).

My research is based on the study of a variety of phenomena using numerical hydro-dynamical simulations. In the last years I have studied different astrophysical topics from the formation of first stars and galaxies in cosmological simulations to black hole growth in idealised galaxy mergers. All my studies are performed using the N-body hydro-dynamical code RAMSES.

I'm interested in the diffuse emission both in total intensity and polarisation. In particular, radio emission in the 20-300 GHz frequency range which is a foreground to observations of the Cosmic Microwave Background.
