Speaker: Linda Tacconi (MPE Garching)

Title: The Evolution of Molecular Gas and Star Formation from the Peak Epoch of Galaxy Formation to the Present

Comprehensive and systematic studies of the molecular content of galaxies during the epochs that are associated with the peak (z~1-2), and subsequent winding down (z<1) of star formation in the Universe are enabling us to illustrate the important role that cold gas, , the fuel for star formation, has played in the assembly of galaxies across cosmic time. Surveys, including COLDGASS and PHIBSS1&2, already provide robust molecular gas detections in hundreds of normal, star forming galaxies, from redshifts 0-2.5. In this talk, we focus on results from PHIBSS, comprising two IRAM Large Programs, where we are we have are mapping the CO J=3-2 or J-2-1 line emission in ~200 such galaxies from z=0.5-2.5; we find that galaxies at these epochs are very gas rich, relative to their star-forming counterparts in the local Universe. We discuss scaling relations for massive star forming galaxies that we derive from these data, and the impact of all of these new observations on our understanding of galaxy evolution in the early Universe.

Title: Astronomical Instrumentation Made in Chile

Since the recognition of Chile as an Astronomical paradise about 50 years ago, 
Chilean Astronomy has grown inflactionary to the proportion of being today 
one of the most productive areas of science in Chile, represented by a well developed 
community at the level of the most developed countries. Today we are facing 
a second phase in this growth with a program aimed at the development in Chile 
of instrumentation for astronomy. This task is being especially challenging 
because of the limiting boundary conditions of a developing country. 
In this talk I will present the efforts carried out in this direction at the Center of 
Astro Engineering UC, the first scientific results obtained with astronomical instruments 
made in Chile and the exciting challenges that we are preparing for the future.
