The Lyman-Alpha and Continuum Origins Survey (LACOS) has HST data of 42 low redshift (z~0.3), compact, star-forming galaxies. For every target, there are reduced images in each of the five filters, Lyman-α line and continuum maps, a general properties catalog, and a preview composite image. All images are corrected for Milky Way extinction (using the Fitzpatrick1999 law) and PSF-matched.
The HST Legacy Archival Uniform Reduction of Local Group Imaging (LAURELIN)is a collection of resolved stellar photometry catalogs for 36 ultra-faint dwarf galaxies within 400kpc from new and archival HST imaging. Additional catalog files contain binary fits tables of photometry for the LAURELIN archival project, as described in Durbin et al. (2025). Measurements were made using the DOLPHOT (Dolphin 2000, Dolphin 2016) PSF photometry package.
Hubble Arp Galaxy Survey (HAGS) provides optical high-resolution images and point source photometry for unusual, disturbed, and/or interacting galaxies from the Arp (1966) and Arp & Madore (1987) catalogs. The resulting galaxy images display rich morphologies, revealing a variety of massive stars, HII regions, stellar clusters, dust lanes, tidal tails, backlit galaxies, and occasional chance superpositions. The atlas images provide a starting point for more detailed studies with high-resolution imaging in other wavelengths, and spectroscopy to track kinematics and the interstellar medium (ISM). Areas of scientific relevance include feedback and star formation in merging and interacting galaxies, resolved stellar populations at the extremes of stellar density, the properties of young massive stars and stellar clusters, the physics of the cold ISM and dust, and stellar and gas dynamics.
Rocky-Worlds is the HLSP for data from the Rocky Worlds DDT program. Data from the first release are now available at MAST! This includes calibrated light curves, model fits, preliminary eclipse depth estimation, and auxiliary data for GJ 3929 b.
