A talk by Dr. Andrew Baker of Rutgers University.

The May AAAP meeting is on the 9th at 7:30PM in Peyton Hall on the Princeton University campus. The talk is on "Dense Gas in Distant Dusty Galaxies" by Dr. Andrew Baker of Rutgers University.

To understand how galaxies evolve across cosmic time, we must understand not only their dark matter and their stars, but also the properties of their interstellar gas, from which new stars form and into which old stars release the products of nucleosynthesis. Cold, "dense" gas, in which hydrogen is largely molecular, constitutes one of the most important yet elusive components of galaxies’ interstellar media. Dr. Baker will describe how radio astronomers use molecular emission lines to detect and characterize dense gas in galaxies. He will then explain how observations of distant galaxies allow us to determine their dense gas masses and their exact distances. Such observations are especially critical for understanding recently discovered populations of galaxies that are so heavily obscured by interstellar dust that they cannot be effectively studied at optical wavelengths.

Prior to the meeting there will be a meet-the-speaker dinner at 6PM at Winberie’s in Palmer Square in Princeton. If you’re interested in attending the dinner please contact by noon on May 9.

We look forward to seeing you at the May meeting and the dinner!
