Blue straggler star (BSS) candidates have been observed in all old dwarf spheroidal galaxies (dSphs), however whether or not they are authentic BSSs or young...
Blue straggler stars in dwarf spheroidal galaxies - II. Sculptor and Fornax
The existence of blue straggler stars (BSSs) in dwarf spheroidal galaxies (dSphs) is still an open question. In fact, many BSS candidates have been observed in...

Context. Galaxy superclusters are the largest systems in the Universe that can give us information about the formation and evolution of the cosmic web. Aims: We...
Bottom-heavy initial mass function in a nearby compact L★ galaxy
We present orbit-based dynamical models and stellar population analysis of Sloan Digital Sky Survey J151741.75-004217.6, a low-redshift (z = 0.116) early-type...
Box- and peanut-shaped bulges. III. A new class of bulges: Thick Boxy Bulges
Inspecting all 1224 edge-on disk galaxies larger than 2arcmin in the RC3 on Digitized Sky Survey (DSS) images (Lütticke et al. cite{lue2000a}) we have found...
Break type and interactions from ultra-deep optical imaging of isolated galaxies
In the standard cosmological model of galaxy evolution, mergers and interactions play a fundamental role in shaping galaxies. Galaxies that are currently...
Breaking the Habit: The Peculiar 2016 Eruption of the Unique Recurrent Nova M31N 2008-12a
Since its discovery in 2008, the Andromeda galaxy nova M31N 2008-12a has been observed in eruption every single year. This unprecedented frequency indicates an...
Breaks and truncations: a unified picture for spiral galaxies
Departures from a simple exponential decay (usually called breaks or truncations) in the surface brightness distribution of galaxy disks are found in the vast...
