Research interests

I am interested in star-forming galaxies and active galactic nuclei (AGN) both in the local universe and at high-z. I mainly use the infrared (IR) spectral range from 1 to 200microns to study the properties of these objects, but always keeping in mind a multi-wavelength (X-ray through radio) approach.

In the local universe I'm currently studying the properties of the so-called Luminous Infrared Galaxies (LIRGs), defined to have IR (8-1000micron) luminosities in the range LIR=10¹¹-10¹²Lsun, and Ultraluminous Infrared Galaxies (ULIRGs) with LIR=10¹²-10¹³Lsun. I use high spatial resolution data (e.g., HST, Spitzer, Gemini/T-ReCS) to characterize the properties of the nuclei (HII or AGN) and circumnuclear HII regions. I'm also interested in the IR emission of nearby Seyfert galaxies,  particularly to derive the properties of the obscuring material. To do so, we compare the nuclear IR SEDs and mid-IR spectra of nearby Seyferts with outputs of torus models to derive properties such as torus size, optical depth, geometry, etc.


I'm also heavily involved in the Spitzer cosmological surveys being conducted by the MIPS Science Team at the University of Arizona. The main goals are to study the properties of IR-selected star forming galaxies, X-ray dectected AGN, and obscured AGN (identified via their radio emission and/or mid-IR properties) at 0.5<z<3.

I'm member of the following science teams: Spitzer/MIPS, Spanish participation in JWST/MIRI, AGN Canari-Cam for GTC, and GOYA for GTC.
