SUMMARY:Dissecting local (U)LIRGs: A near-IR integral field spectroscopy pe

DESCRIPTION:Dissecting local (U)LIRGs: A near-IR integral field spectroscop
 y perspective \nDr. Javier Piqueras\n\nThe importance of Luminous and Ultr
 aluminous infrared galaxies (U/LIRGs)  in the context of the cosmological 
 evolution of the star-formation has  been well established in the last dec
 ades. They have been detected in  large numbers at high-z (z>1) in deep
  surveys with Spitzer and  Herschel, and they seem to be the dominant comp
 onent to the star  formation rate (SFR) density of the Universe beyond z~2
 . Although rare locally, nearby U/LIRGs are valuable candidates to study  
 extreme cases of compact star-formation and coeval AGN. In particular,  th
 e study of local U/LIRGs using near-IR integral field spectroscopic  techn
 iques allows us to disentangle the 2D distribution of the gas and  the sta
 r-formation using high spatial resolution, and characterise  dust-enshroud
 ed, spatially-resolved star-forming regions with great  amount of detail. 
 In that context, we are carrying on a comprehensive 2D IFS near-IR  survey
  of local 10 LIRGs and 12 ULIRGs, based on VLT-SINFONI  observations. I wi
 ll review different topics on the spatially resolved  study of the ISM and
  the star-formation at different spatial scales. I  will focus on the anal
 ysis of the multi-phase gas morphology and  kinematics, and on the study o
 f the spatially-resolved distribution of  the extinction-corrected star-fo
 rmation rate (SFR) and star-formation  rate surface density (ΣSFR). 
 In particular, I will present some recent  results on the characterization
  of individual star-forming regions, in  terms of their sizes and Pa&alpha
 ; luminosities.
