The Impact of Stochastic Attenuation on Photometric Redshift Estimates
Thorsten Tepper García, Uta Fritze-von Alvensleben
We model the attenuation due to HI along a random line of sight (LOS) using differential distribution functions constrained from observations (Kim et al. 97) in a Monte Carlo fashi…
NGC 3310 and Its Tidal Debris: Remnants of Galaxy Evolution
Elizabeth H. Wehner, John S. Gallagher, Polichronis Papaderos +2
NGC 3310 is a local galaxy with an intense, ongoing starburst thought to result from a merger with a companion galaxy. It has several known tidal features in the northwest and sout…
Analysing Globular Cluster observations - Models and Analysis Tools for Lick/IDS indices
Thomas Lilly, Uta Fritze-v. Alvensleben
We have extended our evolutionary synthesis code, GALEV, to include Lick/IDS absorption-line indices for both simple and composite stellar population models (star clusters and gala…
The Impact of Starbursts and Post-Starbursts on the Photometric Evolution of High Redshift Galaxies
Uta Fritze -- v. Alvensleben, Jens Bicker
We present evolutionary synthesis models for galaxies of spectral types Sa through Sd with starbursts of various strengths triggered at various redshifts and study their photometri…
Star Cluster Analyses from Multi-Band Photometry: the Key Advantage of SALT's U-band Sensitivity
Uta Fritze - v. Alvensleben, Polychronis Papaderos, Peter Anders +3
Conventionally, CMD analyses of nearby star clusters are based on observations in 2 passbands. They are plagued by considerable degeneracies between age, metallicity, distance (and…
Metallicity dependent calibrations of flux based SFR tracers
Jens Bicker, Uta Fritze -- v. Alvensleben
We present new calibrations of the widely used H_alpha, [OII], and UV luminosity vs. star formation rate (SFR) relations. Using our evolutionary synthesis code GALEV we compute the…
