Fossil Groups in the Millennium Simulation. Evolution of the Brightest Galaxies
Eugenia Diaz-Gimenez, Hernan Muriel, Claudia Mendes de Oliveira
We create a catalogue of simulated fossil groups and study their properties, in particular the merging histories of their first-ranked galaxies. We compare the simulated fossil gro…
Searching High Redshift Large-Scale Structures: Photometry of Four Fields Around Quasar Pairs at z~1
N. V. Boris, L. Sodre, E. S. Cypriano +3
We have studied the photometric properties of four fields around the high-redshift quasar pairs QP1310+0007, QP1355-0032, QP0110-0219, and QP0114-3140 at z ~ 1 with the aim of iden…
The early-type dwarf galaxy population of the Fornax cluster
S. Mieske, M. Hilker, L. Infante +1
AIMS: We analyse the photometric properties of the early-type Fornax cluster dwarf galaxy population, based on a wide field imaging study of the central cluster area in V and I. We…
A search for ultra-compact dwarf galaxies in the NGC 1023 group of galaxies
S. Mieske, M. J. West, C. Mendes de Oliveira
We present a photometric search for UCD candidates in the nearby galaxy group NGC 1023 (d=11 Mpc) -- the poorest environment searched for UCDs yet --, based on wide field imaging w…
Intra-group diffuse light in compact groups of galaxies. HCG 79, HCG 88 and HCG 95
Cristiano Da Rocha, Claudia Mendes de Oliveira
Deep and images of three Hickson Compact Groups, HCG 79, HCG 88 and HCG 95, were analyzed using a new wavelet technic to measure possible intra-group diffuse light present…
Gas Kinematics of Three Hickson Compact Groups: The Data
H. Plana, P. Amram, C. Mendes de Oliveira +2
We present Fabry Perot observations of three Hickson Compact Groups, HCG 88, HCG 89 and HCG 100. We detect ionized gas in 15 group members, three of which were previously uncatalog…
The Mass Function of Field Galaxies at 0.4 < z < 1.2 Derived From the MUNICS K-Selected Sample
N. Drory, R. Bender, J. Snigula +5
We derive the number density evolution of massive field galaxies in the redshift range 0.4 < z < 1.2 using the K-band selected field galaxy sample from the Munich Near-IR Cluster S…
The Munich Near-Infrared Cluster Survey (MUNICS) - Number density evolution of massive field galaxies to z ~ 1.2 as derived from the K-band selected survey
N. Drory, R. Bender, J. Snigula +5
We derive the number density evolution of massive field galaxies in the redshift range 0.4 < z < 1.2 using the K-band selected field galaxy sample from the Munich Near-IR Cluster S…
Globular Clusters around Galaxies in Groups
C. Da Rocha, C. Mendes de Oliveira, M. Bolte +2
We have obtained deep photometry of NGC 1199 (in HCG 22) and NGC 6868 (in the Telescopium group). Both galaxies are the optically brightest galaxies of their groups. Our analysis o…
The Munich Near-Infrared Cluster Survey - I. Field selection, object extraction, and photometry
N. Drory, G. Feulner, R. Bender +5
The Munich Near-IR Cluster Survey (MUNICS) is a wide-area, medium-deep, photometric survey selected in the K' band. It covers an area of roughly one square degree in the K' and J n…
Candidate tidal dwarf galaxies associated with the Stephan's Quintet
C. Mendes de Oliveira, H. Plana, P. Amram +2
We present kinematic and photometric evidence for the presence of seven candidate tidal dwarf galaxies in Stephan's quintet. The central regions of the two most probable parent gal…
The Dwarf Galaxy Population of the Dorado group down to Mv=-11

We present V and I CCD photometry of suspected low-surface brightness dwarf galaxies detected in a survey covering ~2.4 deg^2 around the central region of the Dorado group of galax…
Kinematics and morphology of ionized gas in Hickson Compact Group 18
H. Plana, P. Amram, C. Mendes de Oliveira +1
We present new observations of emission in the Hickson Compact Group 18 (HCG 18) obtained with a scanning Fabry-Perot interferometer. The velocity field does not show motions…
Wide-Field CCD Photometry of the Globular Cluster M30
Eric L. Sandquist, Michael Bolte, G. E. Langer +2
We present new VI photometry for the halo globular cluster M30 (NGC 7099), and compute luminosity functions (LFs) in both bands for samples of about 15,000 hydrogen-burning stars f…
A NIR search for high-redshift clusters
