Local Kinematics and the Local Standard of Rest
R. Schoenrich, J. Binney, W. Dehnen
We re-examine the stellar kinematics of the Solar neighbourhood in terms of the velocity of the Sun with respect to the local standard of rest. We show that the classical determina…
Cluster Galaxies Die Hard
Simone M. Weinmann, Guinevere Kauffmann, Anja von der Linden +1
We investigate how the specific star formation rates of galaxies of different masses depend on cluster-centric radius and on the central/satellite dichotomy in both field and clust…
The Stellar Mass Components of Galaxies: Comparing Semi-Analytical Models with Observation
Lei Liu, Xiaohu Yang, H. J. Mo +2
We compare the stellar masses of central and satellite galaxies predicted by three independent semianalytical models with observational results obtained from a large galaxy group c…
A Puzzle Involving Galactic Bulge Microlensing Events
Judith G. Cohen, Andrew Gould, Ian B. Thompson +7
We study a sample of 16 microlensed Galactic bulge main sequence turnoff region stars for which high dispersion spectra have been obtained with detailed abundance analyses. We demo…
The impact of feedback on the low redshift Intergalactic Medium
Luca Tornatore, Stefano Borgani, Matteo Viel +1
We analyse the evolution of the properties of the low-redshift Intergalactic Medium (IGM) using high-resolution hydrodynamic simulations that include a detailed chemical evolution…
Chemical evolution of the Galactic bulge as traced by microlensed dwarf and subgiant stars. II. Ages, metallicities, detailed elemental abundances, and connections to the Galactic thick disc
T. Bensby, S. Feltzing, J. A. Johnson +13
The Bulge is the least understood major stellar population of the Milky Way. Most of what we know about the formation and evolution of the Bulge comes from bright giant stars. The…
Chemical abundances for 11 bulge stars from high-resolution, near-IR spectra
N. Ryde, B. Gustafsson, B. Edvardsson +10
It is debated whether the Milky Way bulge has the characteristics of a classical bulge sooner than those of a pseudobulge. Detailed abundance studies of bulge stars is a key to inv…
Radio Mode Outbursts in Giant Elliptical Galaxies
Paul Nulsen, Christine Jones, William Forman +4
Outbursts from active galactic nuclei (AGN) affect the hot atmospheres of isolated giant elliptical galaxies (gE's), as well as those in groups and clusters of galaxies. Chandra ob…
The UV-optical colours of brightest cluster galaxies in optically and X-ray selected clusters
Jing Wang, Roderik Overzier, Guinevere Kauffmann +2
Many brightest cluster galaxies (BCGs) at the centers of X-ray selected clusters exhibit clear evidence for recent star formation. However, studies of BCGs in optically-selected cl…
Elemental abundances in the Galactic bulge from microlensed dwarf stars
T. Bensby, S. Feltzing, J. A. Johnson +11
We present elemental abundances of 13 microlensed dwarf and subgiant stars in the Galactic bulge, which constitute the largest sample to date. We show that these stars span the ful…
Origin and structure of the Galactic disc(s)
Ralph Schoenrich, James Binney
We examine the chemical and dynamical structure in the solar neighbourhood of a model Galaxy that is the endpoint of a simulation of the chemical evolution of the Milky Way in the…
Modelling the Galactic Magnetic Field on the Plane in 2D
T. R. Jaffe, J. P. Leahy, A. J. Banday +3
We present a method for parametric modelling of the physical components of the Galaxy's magnetised interstellar medium, simulating the observables, and mapping out the likelihood s…
Constraining models of the large scale Galactic magnetic field with WMAP5 polarization data and extragalactic Rotation Measure sources
Ronnie Jansson, Glennys R. Farrar, Andre H. Waelkens +1
We introduce a method to quantify the quality-of-fit between data and observables depending on the large scale Galactic magnetic field. We combine WMAP5 polarized synchrotron data…
An OSIRIS study of the gas kinematics in a sample of UV-selected galaxies: Evidence of "Hot and Bothered" starbursts in the local Universe
Antara R. Basu-Zych, Thiago S. Goncalves, Roderik Overzier +6
We present data from Integral Field Spectroscopy for 3 supercompact UV-Luminous Galaxies (ScUVLGs). As nearby (z~0.2), compact (R_50~1-2 kpc), bright Paschen-alpha sources, with un…
Studying Large and Small Scale Environments of Ultraviolet Luminous Galaxies
Antara R. Basu-Zych, David Schiminovich, Sebastien Heinis +23
Studying the environments of 0.4<z<1.2 UV-selected galaxies, as examples of extreme star-forming galaxies (with star formation rates in the range of 3-30 M_sol/yr), we explore the…
The spin and orientation of dark matter halos within cosmic filaments
Youcai Zhang, Xiaohu Yang, Andreas Faltenbacher +3
Clusters, filaments, sheets and voids are the building blocks of the cosmic web. In this study, we present and compare two distinct algorithms for finding cosmic filaments and shee…
O and Na abundance patterns in open clusters of the Galactic disk
G. M. De Silva, B. K. Gibson, J. Lattanzio +1
Aims. A global O-Na abundance anti-correlation is observed in globular clusters, which is not present in the Galactic field population. Open clusters are thought to be chemically h…
Helium-Core White Dwarfs in the Globular Cluster NGC 6397
R. R. Strickler, A. M. Cool, J. Anderson +3
We present results of a study of the central regions of NGC 6397 using Hubble Space Telescope's Advanced Camera for Surveys, focusing on a group of 24 faint blue stars that form a…
Discrete sources as the origin of the Galactic X-ray ridge emission
Revnivtsev M., Sazonov S., Churazov E. +3
An unresolved X-ray glow (at energies above a few kiloelectronvolts) was discovered about 25 years ago and found to be coincident with the Galactic disk -the Galactic ridge X-ray e…
The Dynamical and Chemical Evolution of Dwarf Spheroidal Galaxies
Y. Revaz, P. Jablonka, T. Sawala +8
We present a large sample of fully self-consistent hydrodynamical Nbody/Tree-SPH simulations of isolated dwarf spheroidal galaxies (dSphs). It has enabled us to identify the key ph…
