New surface photometry of all known elliptical galaxies in the Virgo cluster is combined with
published data to derive composite profiles of brightness, ellipticity, position angle, isophote …

We present the results of a deep imaging survey of the Virgo cluster of galaxies,
concentrated around the cores of Virgo subclusters A and B. The goal of this survey was to …

Self-gravitating systems evolve toward the most tightly bound configuration that is reachable
via available evolution processes. The inner parts shrink and the outer parts expand …

We investigate how" extra" or" excess" central light in the surface brightness profiles of cusp
or power-law elliptical galaxies relates to the profiles of ellipticals with cores. The envelopes …

The ultra-deep multiwavelength Hubble Space Telescope Frontier Fields coverage of the
Abell Cluster 2744 is used to derive the stellar population properties of its intracluster light …

We have analysed deep R-band images, down to a limiting surface brightness of 26.5 R-
mag arcsec− 2 (equivalent to∼ 28 B-mag arcsec− 2), of five cD galaxies to determine the …

Massive early-type galaxies typically have two subpopulations of globular clusters (GCs)
which often reveal radial colour (metallicity) gradients. Collating gradients from the literature …

ABSTRACT Canada-France-Hawaii Telescope Megacam data in (g', r', i') are used to obtain
deep, wide-field photometry of the globular cluster system (GCS) around M87. A total of …

We continue our deep optical imaging survey of the Virgo cluster using the CWRU Burrell
Schmidt telescope by presenting B-band surface photometry of the core of the Virgo cluster …

Aims. We present a spectroscopic study of a sample of 287 planetary nebulas (PNs) around
the brightest cluster galaxy (BCG) M 87 in Virgo A, of which 211 are located between 40 kpc …
