לוח שנה משולב

In the last 4 years many measurements of the gas content in galaxies at increasing redshifts have been published. This wave has been driven by new and upgraded instruments in the far-infrared and sub-millimeter that are able to perform such measurements in "normal" z>0.5 galaxies. CO observations receive special attention these days as ALMA enters routine operation phase. But does CO emission trace all the molecular gas? I will discuss the structure of molecular clouds and the so called 'dark gas' that we may be missing.

The Microlensing planet searches are being radically transformed. The event rate is in process of increasing 15-fold to ~50/year in 2015. While this is still small compared to other techniques, microlensing is uniquely capable of probing low-mass planets in the cold outer parts of solar systems. Once thought to be a "purely statistical" method, microlens planet detections now frequently yield detailed information about individual systems, including masses, distances, and orbital motion. These include terrestrial mass planets in Earth-like orbits, multi-planet systems, and planets in binary systems. Microlensing is yielding full orbital solutions of binary lenses (a prospect once
considered preposterous) which opens the way for direct testing by RV followup. I review the recent discoveries made possible by the microlensing revolution, and discuss a second revolution that is now just in its planning stages.
