A large population of recently-quenched red-sequence dwarf galaxies in the outskirts of the Coma Cluster
Russell J. Smith, Ronald O. Marzke, Ann E. Hornschemeier +6
We analyse the stellar populations of 75 red-sequence dwarf galaxies in the Coma cluster, based on high signal-to-noise spectroscopy from the 6.5m MMT. The sample covers a luminosi…
Models for Massive Stellar Populations with Rotation
Gerardo A. Vazquez, Claus Leitherer, Daniel Schaerer +2
We present and discuss evolutionary synthesis models for massive stellar populations generated with the Starburst99 code in combination with a new set of stellar evolution models a…
Constraints on accretion in Ultraluminous X-ray Sources from Spitzer IRS observations of NGC 4485/90: Infrared diagnostic diagrams
Gerardo A. Vazquez, Ann E. Hornschemeier, Edward Colbert +3
Constraining the astrophysical nature of Ultra-Luminous X-ray (ULX) sources, which have X-ray luminosities exceeding 10^39 erg/s, has been elusive due to the optical faintness of a…
Optimization of Starburst99 for Intermediate-Age and Old Stellar Populations
Gerardo A. Vazquez, Claus Leitherer
We have incorporated the latest release of the Padova models into the evolutionary synthesis code Starburst99. The Padova tracks were extended to include the full asymptotic giant…
New Evolutionary Synthesis code. An application to the irregular galaxy NGC 1560
Gerardo A. Vazquez, Leticia Carigi, J. J. Gonzalez
We have developed a new evolutionary synthesis code, which incorporates the output from chemical evolution models. We compare results of this new code with other published codes, a…
