Multi-Phase Gas Physics in the CGM

MPA Special Seminar on Galaxy Formation
I discuss small scale physical processes which affect the formation and survival of warm (T ~ 10^4 K) gas in the CGM, which is crucial for fueling star formation in the host galaxy. In particular, I will discuss thermal instability in the presence of magnetic fields and cosmic rays, and cold gas survival during infall onto the galaxy. [mehr]

Lyman-X day

ORIGINS workshop
The main goal of the workshop is to connect scientists within the Munich community that work on Lyman lines (both emission and absorption; Lyman-alpha, Lyman-beta, ...) and Lyman continuum - so called Lyman-X, and to spark a discussion for future collaborations. The scientific scope is grouped around three main areas: Galaxy formation / evolution How can Lyman-X data bring a new perspective? How can (low-z, z~<3) observations help to constrain the gas in & around galaxies? The Epoch of Reionization (EoR) and the high-z Universe. How the bright Lyman-alpha line can be used to detect the most distant sources, constrain the EoR and help to find the sources driving reionization (e.g., as a proxy for ionizing photon escape)? Large-scale structure / Cosmology. How in particular Lyman-alpha is used in emission (Intensity Mapping) as well as absorption (tomography) as a tool for cosmology to probe the large-scale structure of the Universe with ongoing and future surveys such as HETDEX or DESI? How can simulations and theory aid this process? We expect a fruitful synergy between observational motivations and theoretical developments in a friendly, respectful atmosphere. Because of lunch/coffee arrangements, and to generally help us organize *please register* if you want to attend. [mehr]
