THE HUBBLE SPACE TELESCOPE UV LEGACY SURVEY OF GALACTIC GLOBULAR CLUSTERS. III. A QUINTUPLE STELLAR POPULATION IN NGC 2808 [PDF]
, 2015 In this study we present the first results from multi-wavelength Hubble Space Telescope (HST) observations of the Galactic globular cluster (GC) NGC 2808 as an extension of the Hubble Space Telescope UV Legacy Survey of Galactic GCs (GO-13297 and ...

The SWIRE-VVDS-CFHTLS surveys: stellar mass assembly over the last 10 Gyears. Evidence for a major build up of the red sequence between z=2 and z=1 [PDF]
, 2007 (abridged abstract) We present an analysis of the stellar mass growth over the last 10 Gyrs using a large 3.6$\mu$ selected sample. We split our sample into active (blue) and quiescent (red) galaxies.

Abundances in Stellar Populations [PDF]
Symposium - International Astronomical Union, 1976 Stellar abundances are reviewed with emphasis on large-scale effects which may yield clues to galactic structure and evolution. Spectroscopic and indirect photoelectric abundance criteria are discussed, and utilized.The abundance statistics of nearby galactic disk stars, dominated by M dwarfs, but observed at spectral types F and GV and K III, suggest ...

The detection of an older population in the Magellanic Bridge [PDF]
, 2013 The Magellanic system comprises the Large Magellanic Cloud (LMC), the Small Magellanic Cloud (SMC), and the less frequently observed Magellanic Bridge and Magellanic Stream. The Bridge is traced by neutral gas and has an observed stellar component, while

THE MASSIVE SURVEY. II. STELLAR POPULATION TRENDS OUT TO LARGE RADIUS IN MASSIVE EARLY-TYPE GALAXIES [PDF]
, 2015 We examine stellar population gradients in ∼100 massive early-type galaxies spanning 180 < &sgr; * < 370 ?> km s−1 and MK of −22.5 to −26.5 mag, observed as part of the MASSIVE survey.

Stellar Populations in Galaxies [PDF]
Annual Review of Astronomy and Astrophysics, 1972 There are significant differences among old stellar systems which may partly be a function of luminosity. One such difference is the presence of nuclei in many high luminosity spiral galaxies but their absence in low luminosity irregular systems. Other differences are seen in the spectroscopic and photometric properties.

Stellar Populations in Spiral Galaxies [PDF]
Proceedings of the International Astronomical Union, 2006 We report preliminary results of the characterization of bulge and inner disk stellar populations for 8 nearby spiral galaxies using Gemini/GMOS. The long-slit spectra extend out to 1-2 disk scale lengths with S/N/Ang > 50. Two different model fitting techniques, absorption-line indices and full spectral synthesis, are found to weigh age ...
