Abundance ratios in dwarf elliptical galaxies
Ş. Şen, R. F. Peletier, A. Boselli +14
We determine abundance ratios of 37 dwarf ellipticals (dEs) in the nearby Virgo cluster. This sample is representative of the early-type population of galaxies in the absolute magn…
Virgo Redux: The Masses and Stellar Content of Nuclei in Early-Type Galaxies from Multi-Band Photometry and Spectroscopy
Chelsea Spengler, Patrick Côté, Joel Roediger +14
We present an analysis of 39 nuclei and their early-type hosts in the Virgo Cluster using ten broadband filters: F300W, F475W, F850LP, F160W, , and . We describe the…
Young, metal-enriched cores in early-type dwarf galaxies in the Virgo cluster based on colour gradients
Linda Urich, Thorsten Lisker, Joachim Janz +11
Early-type dwarf galaxies are not simply featureless, old objects, but were found to be much more diverse, hosting substructures and a variety of stellar population properties. To…
The Next Generation Virgo cluster Survey (NGVS). XXVI. The issues of photometric age and metallicity estimates for globular clusters
Mathieu Powalka, Ariane Lançon, Thomas H. Puzia +17
Large samples of globular clusters (GC) with precise multi-wavelength photometry are becoming increasingly available and can be used to constrain the formation history of galaxies.…
Hubble Space Telescope Imaging of the Ultra-Compact High Velocity Cloud AGC 226067: A stripped remnant in the Virgo Cluster
D. J. Sand, A. C. Seth, D. Crnojević +10
We analyze the optical counterpart to the ultra-compact high velocity cloud AGC 226067, utilizing imaging taken with the Advanced Camera for Surveys (ACS) on the Hubble Space Teles…
