We use data from the IAC Stripe82 Legacy Project to study the surface photometry of 22 nearby, face-on to moderately inclined spiral galaxies. The reprocessed and combined Stripe 82 g',r' and I' images allow us to probe the galaxy down to 29-30 r'-magnitudes arcsec-2 and thus reach into the very faint outskirts of the galaxies. Truncations are found in three galaxies. An additional 15 galaxies are found to have an apparent extended stellar halo. Simulations show that the scattering of light… 
Stellar Populations in the Outer Disk and Halo of the Spiral Galaxy M101
We use deep Hubble Space Telescope imaging in the outskirts of the nearby spiral M101 to study stellar populations in the galaxy’s outer disk and halo. Our Advanced Camera for Surveys (ACS) field
Discovery of disc truncations above the galaxies’ mid-plane in Milky Way-like galaxies
Disc truncations are the closest feature to an edge that galaxies have, but the nature of this phenomena is not yet understood. In this paper, we explore the truncations in two nearby (D ~15 Mpc)
The Dragonfly Edge-on Galaxies Survey: Shaping the Outer disk of NGC 4565 via Accretion
We present deep g- and r-band imaging of the well-known edge-on galaxy NGC 4565 (the “Needle Galaxy”), observed as part of the Dragonfly Edge-on Galaxies Survey. The 3σ local surface brightness
An excessively massive thick disc of the enormous edge-on lenticular galaxy NGC 7572
Galactic discs are known to have a complex multilayer structure. An in-depth study of the stellar population properties of the thin and thick components can elucidate the formation and evolution of
Properties of extragalactic thick discs recovered from ultra-deep Stripe82 imaging
Context. Thick discs can give invaluable information on the formation and evolution history of galaxies as most, if not all, disc galaxies have a thin (classical) disc and a thick disc. Aims. We
Ultra-Deep Imaging: Structure of Disks and Haloes
Deep imaging is a fundamental tool in the study of the outermost structures of galaxies. We review recent developments in ultra-deep imaging of galaxy disks and haloes, highlighting the technical
The reports of thick discs’ deaths are greatly exaggerated : thick discs are NOT artefacts caused by diffuse scattered light
Recent studies have made the community aware of scattered light when examining low-surface-brightness galaxy features such as thick discs. In our past studies of the thick discs of edge-on galaxies
Census and classification of low-surface-brightness structures in nearby early-type galaxies from the MATLAS survey
The morphology of galaxies gives essential constraints on the models of galaxy evolution. The morphology of the features in the low-surface-brightness regions of galaxies has not been fully explored
Varied origins of up-bending breaks in galaxy disks
Aims. Using a sample of 175 low-inclination galaxies from the S4G, we investigate the origins of up-bending (Type III) breaks in the 3.6 μm surface brightness profiles of disk galaxies. Methods. We
The Fornax Deep Survey with VST. VII. Evolution and Structure of Late Type Galaxies inside the Virial Radius of the Fornax Cluster
We present the study of a magnitude limited sample (mB < 16.6 mag) of 13 late type galaxies (LTGs), observed inside the virial radius, Rvir 0.7 Mpc, of the Fornax cluster within the Fornax Deep


Point spread function tails and the measurements of diffuse stellar halo light around edge‐on disc galaxies
Measuring the integrated stellar halo light around galaxies is very challenging. The surface brightness of these haloes is expected to be many magnitudes below dark sky and the central brightness of
Stars beyond galaxies: the origin of extended luminous haloes around galaxies
We use numerical simulations to investigate the origin and structure of the luminous haloes that surround isolated galaxies. These stellar structures extend out to several hundred kpc away from a
Tracing Galaxy Formation with Stellar Halos. I. Methods
If the favored hierarchical cosmological model is correct, then the Milky Way system should have accreted ~100-200 luminous satellite galaxies in the past ~12 Gyr. We model this process using a
Stellar substructure in the halo and outer disk of M31
We report the discovery of significant stellar substructure in the halo and outer disk of our nearest large galactic neighbor, M31. Our deep panoramic survey with the Isaac Newton Telescope Wide
A faint red stellar halo around an edge-on disc galaxy in the Hubble Ultra Deep Field
We analyse the detailed structure of a highly-inclined (i > 80°) disc galaxy that lies within the Hubble Ultra Deep Field (UDF). The unprecedented depth of the UDF data allow disc and extraplanar
Quantifying the faint structure of galaxies
Ground-based surveys have mapped the stellar outskirts of Local Group disc galaxies in unprecedented detail, but extending this work to other galaxies is necessary in order to overcome stochastic
Lopsided spiral galaxies and a limit on the galaxy accretion rate
We present a measurement of lopsidedness for the stellar disks of 60 field spiral galaxies in terms of the azimuthal m = 1 Fourier amplitude, A1, of the stellar light. We confirm the previous result
Stellar haloes of disc galaxies at z ∼ 1
Taking advantage of the ultra-deep near-infrared imaging obtained with the Hubble Space Telescope on the Hubble Ultra Deep Field, we detect and explore for the first time the properties of the
Deep CCD Surface Photometry of the Edge-on Spiral NGC 4244
We have obtained deep surface photometry of the edge-on spiral galaxy NGC 4244. Our data reliably reach 27.5 R magnitude arcsec-2, a significant improvement on our earlier deep CCD surface photometry
The formation of disc galaxies in a cosmological context: structure and kinematics
We present results concerning the internal structure and kinematics of disk galaxies formed in cosmologically motivated simulations. The calculations include dark matter, gas dynamics, radiative
