PublicationThe Role of Evolutionary Age and Metallicity in the Formation of Classical Be Circumstellar Disks. II. Assessing the Evolutionary Nature of Candidate Disk Systems
We present the first detailed imaging polarization observations of six SMC and six LMC clusters, known to have large populations of B-type stars that exhibit...

PublicationThe role of grain size in active galactic nuclei torus dust models
Context. Active galactic nuclei (AGN) are surrounded by dust within the central parsecs. The dusty circumnuclear structures, referred to as the torus, are...

PublicationThe Role of Mergers in Galaxy Evolution
In the last decade the importance of mergers in the evolution of galaxies has become evident. In this paper we illustrate this importance by showing examples of...

PublicationThe role of stellar radial motions in shaping galaxy surface brightness profiles
Aims: The physics driving features such as breaks observed in galaxy surface brightness (SB) profiles remains contentious. Here, we assess the importance of...

PublicationThe Role of the Accretion Disk, Dust, and Jets in the IR Emission of Low-luminosity Active Galactic Nuclei
We use recent high-resolution infrared (IR; 1-20 μm) photometry to examine the origin of the IR emission in low-luminosity active galactic nuclei (LLAGN). The...

PublicationThe ROSAT International X-ray/Optical Survey (RIXOS): source catalogue
We describe the ROSAT International X-ray/Optical Survey (RIXOS), a medium-sensitivity survey and optical identification of X-ray sources discovered in ROSAT...

PublicationThe ROSAT UK medium sensitivity survey.
The authors present the first results on the optical identification of 89 ROSAT sources on the second Lockman hole. Because of the low Galactic H I column...

PublicationThe ROSAT UK Medium Sensitivity Survey: optical identification and relation to X-ray spectral properties
We present the first results on the optical identification of 89 sources with S(0.5-2 keV)>=1.7x10^-14 erg s^-1 cm^-2 detected in eight ROSAT Position Sensitive...
