The understanding of the connection between star formation activity and the general properties of galaxies, particularly in active nuclei galaxies, continues under intense study by the astronomical community. We recently conducted a comparative study of the mid- to near-infrared spectroscopic properties of a sample of X-ray selected AGNs from the Swift/BAT 70-month all-sky hard X-ray survey. This sample includes spectral data from both Akari and Spitzer infrared space observatories, including both Seyfert 1 and Seyfert 2 sources. Mid- and Near-Infrared spectral properties such as PAH emission lines, forbidden emission lines and absorption features are studied mainly for investigating the relationship between star-formation and AGN activities.
Photometry is the measurement of the flux of light from astronomical objects. We have performed multi-wavelength observation of stellar objects, including variable stars (classical T-Tauri and d-Scuti stars) and open clusters at the telescopes of the San Pedro Martir National Astronomical Observatory. We were also involved in a monitoring campaign for the determination of spectro-photometric standard stars for the Gaia mission. During the last pair of years we have collaborated with a group of Russian researchers from the BTA telescope studying H-alpha emission from dwarf galaxies of the local volume.
Additionally, due to my previous training as an Electronic Engineer I have been related to various design projects of scientific instrumentation equipment, among them the design of a low-cost electronic modular data-acquisition system for monitoring biometeorological variables.
