Relative velocity of dark matter and barions in clusters of galaxies and measurements of their peculiar velocities
Klaus Dolag, Rashid Sunyaev
The increasing sensitivity of current experiments, which nowadays routinely measure the thermal SZ effect within galaxy clusters, provide the hope that peculiar velocities of indiv…
Bayesian analysis of ages, masses, and distances to cool stars with non-LTE spectroscopic parameters
Aldo Serenelli, Maria Bergemann, Gregory Ruchti +1
For studies of Galactic evolution, the accurate characterization of stars in terms of their evolutionary stage and population membership is of fundamental importance. A standard ap…

Tidal disruptions in circumbinary discs (I): Star formation, dynamics, and binary evolution
Pau Amaro-Seoane, Patrick Brem, Jorge Cuadra
In our current interpretation of the hierarchical structure of the universe it is well established that galaxies collide and merge with each other during their lifetime. If massive…
The ATLAS 3D project - XVI. Physical parameters and spectral line energy distributions of the molecular gas in gas-rich early-type galaxies

We study the global efficiency of star formation in high resolution hydrodynamical simulations of gas discs embedded in isolated early-type and spiral galaxies. Despite using a uni…
Simulations of the galaxy population constrained by observations from z=3 to the present day: implications for galactic winds and the fate of their ejecta
Bruno Henriques, Simon White, Peter Thomas +4
We apply Monte Carlo Markov Chain (MCMC) methods to large-scale simulations of galaxy formation in a LambdaCDM cosmology in order to explore how star formation and feedback are con…
Cosmology from clustering of Lyman-alpha galaxies: breaking non-gravitational Lyman-alpha radiative transfer degeneracies using the bispectrum
Bradley Greig, Eiichiro Komatsu, J. Stuart B. Wyithe
Large surveys for Lyman-alpha emitting (LAE) galaxies have been proposed as a new method for measuring clustering of the galaxy population at high redshift with the goal of determi…
Temperature, gravity and bolometric correction scales for non-supergiant OB stars
Maria-Fernanda Nieva
Context. Precise and accurate determinations of effective temperature and surface gravity are mandatory to derive reliable chemical abundances and fundamental parameters like dista…
Simulating high-z Gamma-ray Burst host galaxies
R. Salvaterra, U. Maio, B. Ciardi +1
We investigate the nature of high-z host galaxies of long Gamma-Ray Bursts (LGRBs) by means of state-of-the-art numerical simulations of cosmic structure formation and evolution of…
Turbulent convection in stellar interiors. III. Mean-field analysis and stratification effects
Maxime Viallet, Casey Meakin, David Arnett +1
We present 3D implicit large eddy simulations (ILES) of the turbulent convection in the envelope of a 5 Msun red giant star and in the oxygen-burning shell of a 23 Msun supernova p…
Nine-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Cosmological Parameter Results
G. Hinshaw, D. Larson, E. Komatsu +18
We present cosmological parameter constraints based on the final nine-year WMAP data, in conjunction with additional cosmological data sets. The WMAP data alone, and in combination…
Nine-Year Wilkinson Microwave Anisotropy Probe (WMAP) Observations: Final Maps and Results
C. L. Bennett, D. Larson, J. L. Weiland +18
We present the final nine-year maps and basic results from the WMAP mission. We provide new nine-year full sky temperature maps that were processed to reduce the asymmetry of the e…
Unification of X-ray winds in Seyfert galaxies: from ultra-fast outflows to warm absorbers
F. Tombesi, M. Cappi, J. N. Reeves +4
The existence of ionized X-ray absorbing layers of gas along the line of sight to the nuclei of Seyfert galaxies is a well established observational fact. This material is systemat…
AGN and QSOs in the eROSITA All-Sky Survey -- Part I: Statistical properties
Alexander Kolodzig, Marat Gilfanov, Rashid Sunyaev +2
Context. The main element of the observing program of the Spectrum-Roentgen-Gamma orbital observatory is a four-year all-sky survey, in the course of which the entire sky will be s…
On the signature of superclusters and voids in the Integrated Sachs-Wolfe effect
Carlos Hernandez-Monteagudo, Robert E. Smith
Through a large ensemble of Gaussian realisations and a suite of large-volume N-body simulations, we show that in a standard LCDM scenario, supervoids and superclusters in the reds…
Hot X-ray coronae around massive spiral galaxies: a unique probe of structure formation models
Akos Bogdan, William R. Forman, Mark Vogelsberger +8
Luminous X-ray gas coronae in the dark matter halos of massive spiral galaxies are a fundamental prediction of structure formation models, yet only a few such coronae have been det…
Modelling the formation of today's massive ellipticals
