Exploring the nature of the Lyman- emitter CR7
Tilman Hartwig, Muhammad A. Latif, Mattis Magg +6
CR7 is the brightest Lyman- emitter observed at , which shows very strong Lyman- and HeII 1640Å line luminosities, but no metal line emission. Previous studies suggest t…
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…
On the nature of star-forming filaments: II. Sub-filaments and velocities
Rowan J. Smith, Simon C. O. Glover, Ralf S. Klessen +1
We show that hydrodynamic turbulent cloud simulations naturally produce large filaments made up of a network of smaller and coherent sub-filaments. Such simulations resemble observ…
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…
Lyman-Werner UV Escape Fractions from Primordial Halos
Anna T. P. Schauer, Daniel J. Whalen, Simon C. O. Glover +1
Population III stars can regulate star formation in the primordial Universe in several ways. They can ionize nearby halos, and even if their ionizing photons are trapped by their o…
How an improved implementation of H2 self-shielding influences the formation of massive stars and black holes
Tilman Hartwig, Simon C. O. Glover, Ralf S. Klessen +2
High redshift quasars at z>6 have masses up to ~ M. One of the pathways to their formation includes direct collapse of gas, forming a supermassive star, precursor of…
New constraints on direct collapse black hole formation in the early Universe
Bhaskar Agarwal, Britton Smith, Simon Glover +2
Direct collapse black holes (DCBH) have been proposed as a solution to the challenge of assembling supermassive black holes by to explain the bright quasars observed at this…
Simulating the formation of massive seed black holes in the early Universe. II: Impact of rate coefficient uncertainties
Simon C. O. Glover
We investigate how uncertainties in the chemical and cooling rate coefficients relevant for a metal-free gas influence our ability to determine the critical ultraviolet field stren…
