THE STELLAR MASS CONTENT OF SUBMILLIMETER-SELECTED GALAXIES [PDF]
The Astrophysical Journal, 2011 We present a new study of the stellar mass in a sample of ~ 70 submillimeter-selected galaxies (SMGs) with accurate spectroscopic redshifts. We fit combinations of stellar population synthesis models and power laws to the galaxies' observed-frame optical through mid-IR spectral energy distributions to separate stellar emission from non-stellar near-IR ...

Stellar Content of Local Group Galaxies - An Introduction [PDF]
Symposium - International Astronomical Union, 1999 In The Realm of the Nebulae, Hubble (1936) first drew attention to the fact that the Milky Way system and the Andromeda galaxy belong to a small cluster that also contains M32, M33, the Magellanic Clouds, NGC 205, NGC 6822 and IC 1613. Hubble also listed IC 10 as a possible member of what he referred to as “the Local Group”. Inspection of the prints of

The Stellar Content of 10 Dwarf Irregular Galaxies [PDF]
The Astronomical Journal, 1998 We examine the stellar content of 10 dwarf irregular galaxies of which broad-band CCD photometry was published in Hopp & Schulte-Ladbeck (1995). We also present Halpha images for several of these galaxies. The galaxies in the sample are located outside of the Local Group.

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.

Structure and stellar content of dwarf galaxies [PDF]
Astronomy and Astrophysics Supplement Series, 2000 We have carried out CCD photometry in the Cousins B and R bands of 15 galaxies in the Canes Venatici I cloud. Total magnitudes, effective radii, effective surface brightnesses, as well as galaxy radii at various isophotal levels in both colors were determined.

Stellar content of NGC 404 – The nearest S0 Galaxy [PDF]
Astronomy & Astrophysics, 2003 We report V−band and I−band CCD stellar and surface photometry of the galaxy NGC 404 , taken with HST WFPC2 and the 2.5 m Nordic telescope. The colour-magnitude diagram for the stars in this galaxy is typical of that of spheroidal systems (i.e. it lacks luminous, young stars but contains a large number of Asymptotic Giant Branch (AGB) and Red Giant ...

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).

Structure and stellar content of dwarf galaxies [PDF]
Astronomy & Astrophysics, 2002 We present B and R band surface photometry of 25 Southern eld dwarf galaxies within a distance of 10 Mpc. For each galaxy we give the essential model-free photometric parameters and, by tting exponentials to the surface brightness proles, the central extrapolated surface brightness and the exponential scale length, in both colour bands.

Ionized Gas and Stellar Content in a Sample of HII Galaxies [PDF]
International Astronomical Union Colloquium, 1989 AbstractWe present the first results of an extensive study of the stellar content and the ionized gas structure for a sample of BCGs. Deep broad (BVRI Johnson) and narrow (Hα) CCD images have been obtained for about 25 galaxies. For a subset of objects, selected on the basis of their apparent structure, long-slit spectroscopy has also been obtained in ...

The Stellar Content of the Nuclei of Spiral Galaxies [PDF]
Highlights of Astronomy, 1983 Numerous studies have been attempted to determine the stellar content of the nuclei of galaxies. In the case of elliptical galaxies observations show that there is a change in spectral type from later to earlier types correlated with a variation from high to low luminosity (e.g. Faber 1977).
