Looking for outflow and infall signatures in high mass star forming regions

P. D. Klaassen, L. Testi, H. Beuther

(Context) Many physical parameters change with time in star forming regions. Here we attempt to correlate changes in infall and outflow motions in high mass star forming regions wi…

The LABOCA Survey of the Extended Chandra Deep Field South: Clustering of submillimetre galaxies

Ryan C. Hickox, J. L. Wardlow, Ian Smail +12

We present a measurement of the spatial clustering of submillimetre galaxies (SMGs) at z = 1-3. Using data from the 870 micron LESS survey, we employ a novel technique to measure t…

The Aquila comparison Project: The Effects of Feedback and Numerical Methods on Simulations of Galaxy Formation

C. Scannapieco, M. Wadepuhl, O. H. Parry +20

We compare the results of thirteen cosmological gasdynamical codes used to simulate the formation of a galaxy in the LCDM structure formation paradigm. The various runs differ in t…

A Dynamical N-body Model for the Central Region of Centauri

B. Jalali, H. Baumgardt, M. Kissler-Patig +4

Supermassive black holes (SMBHs) are fundamental keys to understand the formation and evolution of their host galaxies. However, the formation and growth of SMBHs are not yet well…

Global structure and kinematics of stellar haloes in cosmological hydrodynamic simulations

Ian G. McCarthy, Andreea S. Font, Robert A. Crain +3

We use the Galaxies-Intergalactic Medium Interaction Calculation (GIMIC) suite of cosmological hydrodynamical simulations to study the global structure and kinematics of stellar sp…

The Origin of OB Runaway Stars

Michiko Fujii, Simon Portegies Zwart

About 20% of all massive stars in the Milky Way have unusually high velocities, the origin of which has puzzled astronomers for half a century. We argue that these velocities origi…
