We present Hubble Space Telescope (HST) Wide Field Planetary Camera 2 (WFPC2) photometry of the resolved stellar population in the poststarburst galaxy NGC 1569. The color-magnitude diagram (CMD) derived in the F439W and F555W photometric bands contains ~2800 stars with a photometric error of ≤0.2 mag down to mF439, mF555 26 and is complete for mF555 23. Adopting the literature-distance modulus and reddening, our CMD samples stars more massive than ~4 M☉, allowing us to study the star formation…

Studying the galactic outflow in NGC 1569
We present deep WIYN H alpha imaging of the dwarf irregular starburst galaxy NGC 1569, together with WIYN SparsePak spatially resolved optical spectroscopy of the galactic outflow. This leads on from
Star Cluster Formation and Evolution in the Dwarf Starburst Galaxy NGC 1569
We analyse multi-wavelength Hubble Space Telescope (HST) observations of a large number of star clusters in the nearby (post-) starburst dwarf galaxy NGC 1569. Their spectral energy distributions
How old are the stars in the halo of NGC 5128 (Centaurus A)
Context. NGC 5128 (Centaurus A) is, at the distance of just 3.8 Mpc, the nearest easily observable giant elliptical galaxy. Therefore it is the best target to investigate the early star formation

ABSTRACT We present the results of deep high resolution imaging performed withACS/HRC@HST in the most active region of the nearby starburst galaxy NGC 4214.We resolved the stellar populations of five
Hubble Space Telescope study of resolved red giant stars in the outer halos of nearby dwarf starburst galaxies
Context. Central starbursts in galaxies are an extreme example of ongoing galaxy evolution. The outer parts of galaxies contain a fossil record of galaxy formation and evolution processes in the more


The Stellar Content and the Star Formation History of the Local Group Dwarf Galaxy LGS 3
The star formation history (SFH) and the properties of the dwarf galaxy LGS3 are analyzed using color-magnitude (CM) diagrams plotted from VRI photometry of 736 stars. The distance to the galaxy is
