Globular cluster systems in fossil groups: NGC6482, NGC1132 and ESO306-017
K. A. Alamo-Martínez, M. J. West, J. P. Blakeslee +6
We study the globular cluster (GC) systems in three representative fossil group galaxies: the nearest (NGC6482), the prototype (NGC1132) and the most massive known to date (ESO306-…
On the Shapes and Structures of High-Redshift Compact Galaxies
M. Chevance, A. Weijmans, I. Damjanov +5
Recent deep Hubble Space Telescope WFC3 imaging suggests that a majority of compact quiescent massive galaxies at z~2 may contain disks. To investigate this claim, we have compared…
Luminosities of Barred and Unbarred S0 Galaxies
Sidney van den Bergh
Lenticular galaxies with M_B < -21.5 are almost exclusively unbarred, whereas both barred and unbarred objects occur at fainter luminosity levels. This effect is observed both for…
A Fundamental Line for Elliptical Galaxies
Preethi Nair, Sidney van den Bergh, Roberto G. Abraham
Recent studies have shown that massive galaxies in the distant universe are surprisingly compact, with typical sizes about a factor of three smaller than equally massive galaxies i…
How Different are Normal and Barred Spirals?
Sidney van den Bergh
No significant color differences are found between normal and barred spirals over the range of Hubble stages a - ab - b - bc. Furthermore, no significant difference is seen between…
A Comparison Between the Half-Light Radii, Luminosities, and UBV Colors of Globular Clusters in M31 and the Galaxy
Sidney van den Bergh
The Milky Way System and the Andromeda galaxy experienced radically different evolutionary histories. Nevertheless, it is found that these two galaxies ended up with globular clust…
