Discovery of a new nearby globular cluster with extreme kinematics located in the extension of a halo stream
Dante Minniti, José G. Fernández-Trincado, Matías Gómez +3
Context. We report the discovery of VVV-CL160, a new nearby globular cluster (GC) with extreme kinematics, located in the Galactic plane at deg, deg. Aim…
Wide-field study of the peculiar globular cluster system hosted by the field lenticular NGC 1172
Ana Inés Ennis, Juan Pablo Caso, Lilia Patricia Bassino +2
We present a wide-field study of the globular cluster system (GCS) of the field lenticular galaxy NGC 1172, based on observations from GMOS/Gemini (optical), FourStar/Magellan (NIR…
Radial variation of the stellar mass functions in the globular clusters M15 and M30: clues of a non-standard IMF?
Mario Cadelano, Emanuele Dalessandro, Jeremy J. Webb +5
We exploit a combination of high-resolution Hubble Space Telescope and wide-field ESO-VLT observations to study the slope of the global mass function (alphaG) and its radial variat…
Early-type galaxies in the Antlia Cluster: global properties
J. P. Calderón, L. P. Bassino, S. A. Cellone +2
We present an extension of our previous research on the early-type galaxy population of the Antlia cluster (d ~ 35 Mpc), achieving a total coverage of ~ 2.6 deg x deg and performin…
Globular cluster systems as tracers of the evolutionary history in NGC 3258 and NGC 3268
Juan Pablo Caso, Lilia P. Bassino, Matías Gómez
We present a new photometric study of NGC 3258 and NGC 3268 globular cluster systems (GCSs), using images in filters and , obtained from four different telescopes.…
The curious case of the companion: evidence for cold accretion onto a dwarf satellite near the isolated elliptical NGC 7796
T. Richtler, M. Hilker, K. Voggel +4
The isolated elliptical (IE) NGC 7796 is accompanied by an interesting early-type dwarf galaxy, named NGC7796-DW1. It exhibits a tidal tail, very boxy isophotes, and multiple nucle…
Early-type galaxies in the Antlia Cluster: Catalogue and isophotal analysis
Juan P. Calderón, Lilia P. Bassino, Sergio A. Cellone +1
We present a statistical isophotal analysis of 138 early-type galaxies in the Antlia cluster, located at a distance of Mpc. The observational material consists of CCD i…
The globular cluster system of NGC 1316 IV. Nature of the star cluster complex SH2
T. Richtler, B. Husemann, M. Hilker +3
The light of the merger remnant NGC 1316 is dominated by old and intermediate-age stars. The only sign of current star formation in this big galaxy is the HII region SH2, an isolat…
Globular Cluster Scale Sizes in Giant Galaxies: Orbital Anisotropy and Tidally Under-filling Clusters in M87, NGC 1399, and NGC 5128
Jeremy J. Webb, Alison Sills, William E. Harris +4
We investigate the shallow increase in globular cluster half-light radii with projected galactocentric distance observed in the giant galaxies M87, NGC 1399, and NGC 5128.…
Footprints in the sand: What can globular clusters tell us about NGC 4753 past?
Juan Pablo Caso, Lilia P. Bassino, Matías Gómez
NGC 4753 is a bright (M_V approx -22.3) lenticular galaxy. It is a very interesting target to test different theories of formation of lenticular galaxies, due to its low-density en…
Early-type galaxies in the Antlia Cluster: A deep look into scaling relations
Juan P. Calderón, Lilia P. Bassino, Sergio A. Cellone +3
We present the first large-scale study of the photometric and structural relations followed by early-type galaxies (ETGs) in the Antlia cluster. Antlia is the third nearest populou…
