Dancing in the void: hydrodynamical N-body simulations of the extremely metal poor galaxy DDO 68
R. Pascale, F. Annibali, M. Tosi +7
Using hydrodynamical -body simulations, we show that the observed structure and kinematics of the extremely metal-poor, dwarf irregular galaxy DDO 68 is compatible with a merger…
STEP Survey II: Structural Analysis of 170 star clusters in the SMC
M. Gatto, V. Ripepi, M. Bellazzini +9
We derived surface brightness profiles in the \emph{g} band for 170 Small Magellanic Cloud (SMC) star clusters (SCs) mainly located in the central region of the galaxy. We provide…
YMCA-1: a new remote star cluster of the Milky Way?
M. Gatto, V. Ripepi, M. Bellazzini +11
We report the possible discovery of a new stellar system (YMCA-1), identified during a search for small scale overdensities in the photometric data of the YMCA survey. The object's…
Revisiting Attenuation Curves: the Case of NGC 3351
Daniela Calzetti, Andrew J. Battisti, Irene Shivaei +14
Multi-wavelength images from the farUV (~0.15 micron) to the sub-millimeter of the central region of the galaxy NGC 3351 are analyzed to constrain its stellar populations and dust…
Reaching the oldest stars beyond the Local Group: ancient star formation in UGC 4483
Elena Sacchi, Alessandra Aloisi, Matteo Correnti +9
We present new WFC3/UVIS observations of UGC 4483, the closest example of a metal-poor blue compact dwarf galaxy, with a metallicity of and located at a…
The star formation history of Eridanus II: on the role of SNe feedback in the quenching of ultra-faint dwarf galaxies
C. Gallart, M. Monelli, T. Ruiz-Lara +17
Eridanus II (EriII) is an ultra-faint dwarf (UFD) galaxy (M_V=-7.1) located at a distance close to the Milky Way virial radius. Early shallow color-magnitude diagrams (CMD) indicat…
