The Stellar Content of the Isolated Transition Dwarf Galaxy DDO210 [PDF]

Monthly Notices of the Royal Astronomical Society, 2006
We use Subaru Suprime-Cam and VLT FORS1 photometry of the dwarf galaxy DDO210 to study the global stellar content and structural properties of a transition-type galaxy (with properties intermediate between dwarf irregular and dwarf spheroidal systems).

Spectroscopic Characterization of the Stellar Content of Ultra-Diffuse Galaxies [PDF]

Monthly Notices of the Royal Astronomical Society, 2018
Understanding the peculiar properties of Ultra Diffuse Galaxies (UDGs) via spectroscopic analysis is a challenging task requiring very deep observations and exquisite data reduction. In this work we perform one of the most complete characterisations of the stellar component of UDGs to date using deep optical spectroscopic data from OSIRIS at GTC.

The stellar content of a prototype double barred galaxy

Astrophysics and Space Science, 2003
High spatial resolution visible and NIR observations of the bar of NGC 5850, a prototype of double barred spirals, together with visible intermediate and high dispersion spectra along the primary bar, are being used, with the aid of simple stellar population synthesis models, to investigate the mean age and metallicity of the different stellar ...

Stellar content and kinematics of starburst galaxies

AIP Conference Proceedings, 1997
We present the Far Ultraviolet (FUV) spectra of four nearby starburst galaxies. We analyse them in terms of the stellar content and the kinematics of the interstellar medium and we discuss the implications of these results for the interpretation of the UV spectra of high redshift galaxies.
