Research Experience
Observatory project
Observatory project at Paranal, observation of faint stars with SPHERE to test the contrast obtained with or without the choronograph. The results of this projects are included in the SPHERE user manual.
Research project
Modeling of the possible observed trajectory on the sky of the system V471 Tau by combining a code designed for orbital motion, Hipparcos data, LTT analysis and some orbital parameters from previous research in order to confirm that with the high precision of Gaia’s astrometric measurements we would be able to find the missing pieces of V471 Tau, under supervision of Dr. Schreiber
Research practice “The search for exoplanetary transit candidates around M dwarf stars using VVV survey data”
Performing a colour-based selection of M dwarfs in the VVV b201 tile, estimating their subtypes using VISTA multi-band photometry and searching for transit-like light curves from the first 26 epochs of the survey, under supervision of Dr. Minniti and Dr. Rojas (Rojas-Ayala, Iglesias, et al. 2014)
Relevant Experience
Observing Experience
I have professional observing experience with different high-resolution spectrographs covering the UV-optical wavelength range. My experience includes:
- 9 nights observing with FEROS echelle spectrograph mounted at the MPG/ESO-2.20m telescope at La Silla Observatory
- 4 nights with MIKE echelle spectrograph mounted at the Clay telescope at Las Campanas Observatory
- 10 nights wit HARPS echelle spectrograph mounted at the 3.6m telescope at La Silla Observatory
- 2 hours observing with SPHERE instrument at Paranal Observatory on imaging mode.
I also have quite some experience preparing Observing Blocks via P2PP (ESO software) and the new P2 online tool for large amounts of targets. In addition, I have a succesful proposal record with 13 observing proposals accepted as PI; 6 ESO proposals, 6 CNTAC and 1 ALMA proposals, adding a total of 206 hours of granted telescope time in service mode and 6 nights in visitor mode. I have already published results from some of those programs in Iglesias et al. (2018).
Computer Skills
I mostly code in Python (and i-Python), but in the past I have coded in Supermongo, Java, C++ and Basics. I manage all my spectroscopic data using my own Python scripts, which read all different kinds of data products (1D spectra, 2D spectra, multispec, etc.), apply barycentric radial velocity corrections, read and use information from the header, apply normalization to the continuum, combine several observations, fit spectral lines, analyze variability from different observations, fit residual absorptions, compute radial velocities, etc., all these automatized for large amounts of data from different objects.
I am also familiar with different astronomical and science related Python packages and use them to manage my data, compute statistics, perform queries to databases, build my own SQL database, etc.
I manage several astronomical packages and tools such as IRAF, ds9 and MESA, I use VO-tools like TOPCAT, Aladin, VOSA and the Dunes “VO-discovery tool”, and I frequently query databases like ESO, Simbad, Vizier, Gaia and SDSS to search for data, catalogs, stellar parameters, etc.
In addition, I am familiar with software related to spectroscopy such as Molecfit, a tool developed at ESO (Kausch et al. 2015; Smette et al. 2015) to perform telluric lines corrections, and the spectral synthesis codes SYNTHE and ATLAS 9 (Sbordone et al. 2004) to obtain synthetic spectra from Kurucz models (Castelli et al. 1997). I have automatized the use of these tools using python to, for instance, perform telluric corrections for large amounts of spectra from several instruments (having different spectral resolution and header keywords), and compute grids of Kurucz models with diverse combinations of parameters to find the best fitting spectral model for each object.
