  IAA||Infrared observations of the Galactic Center|| The Galactic center is located at a distance of just 8 kpc from the Solar System, 100 times closer than the next comparable nucleus in a spiral galaxy, and 1000 times closer than the next active galactic nucleus. Therefore, the center of our Galaxy serves as a unique laboratory to investigate the physical processes at the bottom of the potential of a common spiral galaxy. On its way to the Solar System, the radiation emitted at the

center of the Milky Way has to traverse dense clouds of gas and dust in the Galactic plane. It is consequently subject to strong extinction. Therefore, one can study the Galaxy center only at radio and infrared wavelengths, and in the X-ray regime. In this talk I will present the results of infrared observations of the Galactic center, with a particular emphasis on the nuclear star cluster and the massive black hole, Sagittarius A*, which is located at the very dynamical center of the Milky Way. ||

  Jun 18 15:00	Christof Buchbender	An In-Depth Study of the Interstellar Medium in the Barred Spiral Galaxy NGC3627	I will present a study of the cold, dense, star forming ISM in the barred spiral galaxy NGC3627, with the final goal to obtain a spatially resolved Schmidt-Kennicutt law, which is a power law relation between the star formation rate (SFR) and the gas mass surface density. NGC3627 is located in the nearby Leo Triplet with a distance of about 9 Mpc. It is strongly interacting with its nearest neighbor NGC3628 and as such, it is representative for a large number of galaxies where gravitational interaction has triggered the formation of a bar and the associated SF activity along the bar and in the nuclear region. To investigate the molecular gas in NGC3627 measurements of the CO(1-0) line as well as 1.2 dust continuum emission were used. With these two tracers of molecular mass at hand it is possible to study local variations of the X-factor, which relates CO(1-0) intensity to H$_2$ column density, across the disk of the galaxy. These observations are complemented by HI, Halpha, and 24,70 and 160 micron Spitzer observations, allowing to determine dust temperatures, SFRs, and atomic gas masses. This comprehensive wavelength coverage provides a good view into the structure of the different components of the cold ISM in this galaxy.
  June 3rd 17:00	Rebeca Aladro	Chemical differences between two types of starburst galaxies
  May 15th 13:00	Javier Adrian Rodon MPIA Heidelberg	The Core Mass Function of IRAS 19410+2336
  May 5th 13:00	Manuel Gonzalez Garcia OBSPM	Infrared pumping of molecular lines in PDRs	The arrival of new instruments such as Herschel or ALMA opens new resarch possibilities. Astrophysical models such as the Meudon PDR code will be very important to prepare and analyse furure observations. We will explain how we have improved the grain model of PDR Meudon code, by making an interface with DUSTEM code. We will also explain that an exact computation of the infrared pumping term has to be done if we want to accurately describe excitation of some molecules, such as water. Finally we will show how these improvements permits us to describe the objects S140 and M82.

  November 13th 13:00	Jeffrey Wagg	Submm-to-radio observations of molecular and atomic gas in massive high-redshift galaxies	The current generation of large single-dish submm/radio-wavelength telescopes and interferometers have opened up the study of gas and dust in galaxies and AGN out to the epoch of reionization at z>6. The IRAM facilities have been at the forefront of this revolution, and I will present our most recent results of an ongoing survey of dust continuum emission and molecular CO line emission in z~6 quasars using the CSO, the IRAM 30m, the PdBI and the GBT. I will also present our first attempts at using observations of redshifted CO line emission as a means of measuring redshifts for dust-obscured submm galaxies. Finally, I will discuss some of the applications of redshifted atomic lines such as neutral and ionized Carbon for studying star-formation in the first galaxies.
