PublicationThe Odd Offset between the Galactic Disk and Its Bar in NGC~3906
We use mid-infrared 3.6 and 4.5 μm imaging of NGC 3906 from the Spitzer Survey of Stellar Structure in Galaxies (S4G) to understand the nature of an unusual...

PublicationThe Onset of a Three-Galaxy Merger in the Compact Group of Galaxies HCG 95?
In this Letter we report new evidence for a close three-galaxy interaction in the compact group of galaxies HCG 95. Deep optical imaging in the Johnson UBVRI...

PublicationThe optical behaviour of BL Lacertae at its maximum brightness levels: a blend of geometry and energetics
In 2021 BL Lacertae underwent an extraordinary activity phase, which was intensively followed by the Whole Earth Blazar Telescope (WEBT) Collaboration. We...

PublicationThe optical morphologies of the 2 Jy sample of radio galaxies: evidence for galaxy interactions
We present deep Gemini Multi-Object Spectrograph South (GMOS-S)/Gemini optical broad-band images for a complete sample of 46 southern 2 Jy radio galaxies at...

PublicationThe optical properties of low redshift radio galaxies
We present morphological and photometric properties of 79 low redshift (z=-24.0 with a clear trend for FRI sources to be ~ 0.5 mag brighter than FRII galaxies...

PublicationThe Orbit and Origin of the Ultra-faint Dwarf Galaxy Segue 1
We present the first proper motion measurement for an ultra-faint dwarf spheroidal galaxy, Segue 1, using data from the Sloan Digital Sky Survey (SDSS) and the...

PublicationThe Orientation of Disk Galaxies around Large Cosmic Voids
Using a large sample of galaxies from the the seventh data release of the Sloan Digital Sky Survey (SDSS-DR7), we have analyzed the alignment of disk galaxies...

PublicationThe orientation of galaxy dark matter haloes around cosmic voids
Using the Millennium N-body Simulation we explore how the shape and angular momentum of galaxy dark matter haloes surrounding the largest cosmological voids are...
