Star Clusters in M 31. IV. A Comparative Analysis of Absorption Line Indices in Old M 31 and Milky Way Clusters
Ricardo P. Schiavon, Nelson Caldwell, Heather Morrison +4
We present absorption line indices measured in the integrated spectra of globular clusters both from the Galaxy and from M 31. Our samples include 41 Galactic globular clusters, an…
An Investigation of Sloan Digital Sky Survey Imaging Data and Multi-Band Scaling Relations of Spiral Galaxies (with Dynamical Information)
Melanie Hall, Stephane Courteau, Aaron A. Dutton +2
We have compiled a sample of 3041 spiral galaxies with multi-band gri imaging from the Sloan Digital Sky Survey (SDSS) Data Release 7 and available galaxy rotational velocities der…
Magnetic fields in the Large-Scale Structure of the Universe
Dongsu Ryu, Dominik R. G. Schleicher, Rudolf A. Treumann +2
Magnetic fields appear to be ubiquitous in astrophysical environments. Their existence in the intracluster medium is established through observations of synchrotron emission and Fa…
The First Magnetic Fields
Lawrence M. Widrow, Dongsu Ryu, Dominik Schleicher +3
We review current ideas on the origin of galactic and extragalactic magnetic fields. We begin by summarizing observations of magnetic fields at cosmological redshifts and on cosmol…
Peaks above the Maxwellian Sea: A New Approach to Finding Substructure in N-Body Haloes
Pascal J. Elahi, Robert J. Thacker, Lawrence M. Widrow
We describe a new algorithm for finding substructures within dark matter haloes from N-body simulations. The algorithm relies upon the fact that dynamically distinct substructures…
The Luminosity Profile and Structural Parameters of the Andromeda Galaxy
Stephane Courteau, Lawrence M. Widrow, Michael McDonald +5
We have constructed an extended composite luminosity profile for the Andromeda galaxy, M31, and have decomposed it into three basic luminous structural components: a bulge, a disk…
A Survey of 286 Virgo Cluster Galaxies at Optical griz and Near-IR H-band: Surface Brightness Profiles and Bulge-Disk Decompositions
Michael McDonald, Stephane Courteau, R. Brent Tully +1
We present griz and H-band surface brightness profiles and bulge-disk decompositions for a morphologically-broad sample of 286 Virgo cluster galaxies. The H-band data come from a v…
Gemini/GMOS Imaging of Globular Cluster Systems in Five Early-type Galaxies
Favio R. Faifer, Juan C. Forte, Mark A. Norris +7
This paper presents deep high quality photometry of globular cluster (GC) systems belonging to five early-type galaxies covering a range of mass and environment. Photometric data w…
Combined Limits on WIMPs from the CDMS and EDELWEISS Experiments
CDMS, EDELWEISS Collaborations, : +114
The CDMS and EDELWEISS collaborations have combined the results of their direct searches for dark matter using cryogenic germanium detectors. The total data set represents 614 kg.d…
The Formation and Evolution of Virgo Cluster Galaxies - I. Broadband Optical & Infrared Colours
Joel C. Roediger, Stephane Courteau, Michael McDonald +1
We use a combination of deep optical (gri) and near-infrared (H) photometry to study the radially-resolved colours of a broad sample of 300 Virgo cluster galaxies. For most galaxy…
Internal gamma gamma-opacity in Active Galactic Nuclei and the consequences for the TeV observations of M87 and Cen A
Katharina A. Brodatzki, David J. S. Pardy, Julia K. Becker +1
Low Luminosity Active Galactic Nuclei (LLAGNs) possess the characteristic features of more luminous Active Galactic Nuclei (AGNs) but exhibit a much lower nuclear Halpha luminosity…
Dark Matter Search Experiments
Wolfgang Rau
Astronomical and cosmological observations of the past 80 years build solid evidence that atomic matter makes up only a small fraction of the matter in the universe. The dominant f…
Exploring the Properties of the M31 Halo Globular Cluster System
A. P. Huxor, A. M. N. Ferguson, N. R. Tanvir +6
Following on from our discovery of a significant population of M31 outer halo globular clusters (GCs), and updates to the Revised Bologna Catalogue of M31 GCs, we investigate the G…
