IFUM Integrated Field Spectroscopy of Ten M104 Satellite Galaxy Candidates
Ethan Crosby, Mario Mateo, Ivanna Escala +3
We report the spectroscopic analysis of ten satellite galaxy candidates in the sphere of influence of the Sombrero galaxy (M104, NGC4594), based on data obtained with IFUM (Integra…
New dwarf galaxy candidates in the sphere of influence of the Sombrero galaxy
Ethan Crosby, Helmut Jerjen, Oliver Müller +3
We report the discovery of 40 new satellite dwarf galaxy candidates in the sphere of influence of the Sombrero galaxy (M104) the most luminous galaxy in the Local Volume. Using the…
New dwarf galaxy candidates in the sphere of influence of the Local Volume spiral galaxy NGC2683
E. Crosby, H. Jerjen, O. Müller +3
We present initial results of a survey of host galaxies environments in the Local Volume (Mpc) searching for satellite dwarf galaxy candidates using the wide-field…
Chemical Compositions of Field and Globular Cluster RR~Lyrae Stars: II. omega Centauri
D. Magurno, C. Sneden, G. Bono +21
We present a detailed spectroscopic analysis of RR Lyrae (RRL) variables in the globular cluster NGC 5139 (omega Cen). We collected optical (4580-5330 A), high resolution (R = 34,0…
On a new method to estimate distance, reddening and metallicity of RR Lyrae stars using optical/near-infrared (,,,,,) mean magnitudes: Centauri as a first test case
G. Bono, G. Iannicola, V. F. Braga +26
We developed a new approach to provide accurate estimates of metal content, reddening and true distance modulus of RR Lyrae stars (RRLs). The method is based on homogeneous optical…
The extensive age gradient of the Carina dwarf galaxy
Giuseppina Battaglia, Michael Irwin, Eline Tolstoy +2
The evolution of small systems such as dwarf spheroidal galaxies (dSph) is likely to have been a balance between external environmental effects and internal processes within their…
