High molecular gas fractions in normal massive star-forming galaxies in the young Universe
TLDR
A survey of molecular gas in samples of typical massive-star-forming galaxies at mean redshifts of about 1.2 and 2.3 reveals that distant star forming galaxies were indeed gas rich, and that the star formation efficiency is not strongly dependent on cosmic epoch.
The Structure of Dark Matter Halos in Dwarf Galaxies
Recent observations indicate that dark matter halos have flat central density profiles. Cosmological simulations with nonbaryonic dark matter, however, predict self-similar halos with central density
Kinetic Energy Decay Rates of Supersonic and Super-Alfvénic Turbulence in Star-Forming Clouds
We compute 3D models of supersonic, sub-Alfvenic, and super-Alfvenic decaying turbulence, with an isothermal equation of state appropriate for star-forming interstellar clouds of molecular gas. We
THE SINS SURVEY OF z ∼ 2 GALAXY KINEMATICS: PROPERTIES OF THE GIANT STAR-FORMING CLUMPS*
We have studied the properties of giant star-forming clumps in five z ~ 2 star-forming disks with deep SINFONI AO spectroscopy at the ESO VLT. The clumps reside in disk regions where the Toomre
Bulge n and B/T in High Mass Galaxies: Constraints on the Origin of Bulges in Hierarchical Models
We use the bulge Sersic index n and bulge-to-total mass ratio (B/T) to explore the fundamental question of how bulges form. We perform two-dimensional bulge-disk-bar decomposition on H-band images of
Resolution requirements for smoothed particle hydrodynamics calculations with self-gravity
We determine a new resolution requirement for the smoothed particle hydrodynamics (SPH) numerical method when self-gravity is included. Comparison calculations between an SPH code and an Eulerian
PHIBSS: Unified Scaling Relations of Gas Depletion Time and Molecular Gas Fractions
This paper provides an update of our previous scaling relations (Genzel et al.2015) between galaxy integrated molecular gas masses, stellar masses and star formation rates, in the framework of the
A gas cloud on its way towards the supermassive black hole at the Galactic Centre
TLDR
The presence of a dense gas cloud approximately three times the mass of Earth that is falling into the accretion zone of Sagittarius A*, a compact radio source at the Galactic Centre, is reported.
THE SINS SURVEY: MODELING THE DYNAMICS OF z ∼ 2 GALAXIES AND THE HIGH-z TULLY-FISHER RELATION*
We present the modeling of SINFONI integral field dynamics of 18 star-forming galaxies at z ~ 2 from Hα line emission. The galaxies are selected from the larger sample of the SINS survey, based on
THE TWO PHASES OF GALAXY FORMATION
Cosmological simulations of galaxy formation appear to show a "two-phase" character with a rapid early phase at z 2 during which "in situ" stars are formed within the galaxy from infalling cold gas
