Abstract:
Most galaxies in the universe spend their lives inhabiting what is called the main-sequence (MS) of star-formation, a relatively peaceful state in which galaxies form stars and feed their central massive black holes (BHs) in a steady manner. However, both simulations and observations suggest that, at least once within their life-times, galaxies undergo a merger event during which their star formation efficiencies and BH accretion rates drastically increase over a short period of time. This phase is fundamental to our understanding of the main physical processes that drive the evolution of galaxies over cosmic time, but it occurs behind a thick blanket of gas and dust that obscures the very luminous, central power source(s), making them detectable only in the infrared. In this talk I will present results obtained from recent observations of nearby and high-redshift luminous infrared galaxies, for which in-depth studies of their interstellar medium have been only made possible by the advent of state-of-the-art infrared/sub-mm facilities such as ALMA and JWST.
Short Bio:
Tanio Diaz Santos obtained his BSc in Physics in 2003 as well as his MSc in 2005 from Universidad Complutense de Madrid (Spain). In 2009 he was awarded his PhD in Astrophysics from Spanish National Research Council (CSIC) with a thesis entitled “A Mid-infrared Study of Local Luminous Infrared Galaxies”.From 2009 until 2011 he was a postdoctoral researcher at the Dept. of Physics of the Univ. of Crete (Greece) before moving to the Spitzer Science Center at the California Institute of Technology (USA) as a postdoctoral researcher during 2011-2014. He was an ALMA-CONICYT fellow at the Nucleo de Astronomia, Universidad Diego Portales (Chile) from 2014 until 2019 as well as a CAS-CONICYT Fellow from 2019 until 2020. He was elected at IA-FORTH as Associate Researcher in 2020.
