Multiple stellar populations in Magellanic Cloud clusters. V. The split main sequence of the young cluster NGC1866
A. P. Milone, A. F. Marino, F. D'Antona +7
One of the most unexpected results in the field of stellar populations of the last few years, is the discovery that some Magellanic-Cloud globular clusters younger than ~400 Myr, e…
Large-scale filamentary structures around the Virgo cluster revisited
Suk Kim, Soo-Chang Rey, Martin Bureau +9
We revisit the filamentary structures of galaxies around the Virgo cluster, exploiting a larger dataset based on the HyperLeda database than previous studies. In particular, this i…
Testing the two planes of satellites in the Centaurus Group
Oliver Müller, Helmut Jerjen, Marcel S. Pawlowski +1
The existence of satellite galaxy planes poses a major challenge for the standard picture of structure formation with non-baryonic dark matter. Recently Tully et al. (2015) reporte…
Portrait of a Dark Horse: a Photometric and Spectroscopic Study of the Ultra-faint Milky Way Satellite Pegasus III
Dongwon Kim, Helmut Jerjen, Marla Geha +6
Pegasus III (Peg III) is one of the few known ultra-faint stellar systems in the outer halo of the Milky Way. We present the results from a follow-up campaign with Magellan/IMACS a…
Extended stellar substructure surrounding the Boötes I dwarf spheroidal galaxy
T. A. Roderick, A. D. Mackey, H. Jerjen +1
We present deep stellar photometry of the Boötes I dwarf spheroidal galaxy in g and i band filters, taken with the Dark Energy Camera at Cerro Tololo in Chile. Our analysis reveals…
New low surface brightness dwarf galaxies in the Centaurus group
Oliver Müller, Helmut Jerjen, Bruno Binggeli
We conducted an extensive CCD search for faint, unresolved dwarf galaxies of very low surface brightness in the whole Centaurus group region encompassing the Cen A and M 83 subgrou…
