Hunting for the signatures of molecular cloud formation
Simon C. O. Glover, Paul C. Clark
In order to understand how molecular clouds form in the Galactic interstellar medium, we would like to be able to map the structure and kinematics of the gas flows responsible for…
Impact of supernova and cosmic-ray driving on the surface brightness of the galactic halo in soft X-rays
Thomas Peters, Philipp Girichidis, Andrea Gatto +7
The halo of the Milky Way contains a hot plasma with a surface brightness in soft X-rays of the order erg cm s deg. The origin of this gas is unclear…
Star formation and molecular hydrogen in dwarf galaxies: a non-equilibrium view
Chia-Yu Hu, Thorsten Naab, Stefanie Walch +2
We study the connection of star formation to atomic (HI) and molecular hydrogen (H) in isolated, low metallicity dwarf galaxies with high-resolution ( = 4 M$_\odot…
Launching cosmic-ray-driven outflows from the magnetized interstellar medium
Philipp Girichidis, Thorsten Naab, Stefanie Walch +10
We present a hydrodynamical simulation of the turbulent, magnetized, supernova (SN)-driven interstellar medium (ISM) in a stratified box that dynamically couples the injection and…
Synthetic observations of molecular clouds in a galactic center environment: I. Studying maps of column density and integrated intensity
Erik Bertram, Simon C. O. Glover, Paul C. Clark +2
We run numerical simulations of molecular clouds (MCs), adopting properties similar to those found in the Central Molecular Zone (CMZ) of the Milky Way. For this, we employ the mov…
Is atomic carbon a good tracer of molecular gas in metal-poor galaxies?
Simon C. O. Glover, Paul C. Clark
Carbon monoxide (CO) is widely used as a tracer of molecular hydrogen (H2) in metal-rich galaxies, but is known to become ineffective in low metallicity dwarf galaxies. Atomic carb…
The SILCC (SImulating the LifeCycle of molecular Clouds) project - II. Dynamical evolution of the supernova-driven ISM and the launching of outflows
Philipp Girichidis, Stefanie Walch, Thorsten Naab +8
The SILCC project (SImulating the Life-Cycle of molecular Clouds) aims at a more self-consistent understanding of the interstellar medium (ISM) on small scales and its link to gala…
Does the CO-to-H2 conversion factor depend on the star formation rate?
Paul C. Clark, Simon C. O. Glover
We present a series of numerical simulations that explore how the `X-factor', -- the conversion factor between the observed integrated CO emission and the column density o…
TOPoS: II. On the bimodality of carbon abundance in CEMP stars. Implications on the early chemical evolution of galaxies
P. Bonifacio, E. Caffau, M. Spite +18
In the course of the TOPoS (Turn Off Primordial Stars) survey, aimed at discovering the lowest metallicity stars, we have found several carbon-enhanced metal-poor (CEMP) stars. We…
The role of 3-body H formation in the fragmentation of primordial gas
Jayanta Dutta, Biman B. Nath, Paul C. Clark +1
It has been shown that the behaviour of primordial gas collapsing in a dark matter minihalo can depend on the adopted choice of 3-body H formation rate. The uncertainties in th…
