Galaxy structure in the ultraviolet: the dependence of morphological parameters on rest-frame wavelength (2018)
Journal Article
Mager, V. A., Conselice, C. J., Seibert, M., Gusbar, C., Katona, A. P., Villari, J. M., …Windhorst, R. A. (2018). Galaxy structure in the ultraviolet: the dependence of morphological parameters on rest-frame wavelength. Astrophysical Journal, 864(2), doi:10.3847/1538-4357/aad59e. ISSN 1538-4357

Evolutionary studies that compare galaxy structure as a function of redshift are complicated by the fact that any particular galaxy's appearance depends in part on the rest-frame wavelength of the observation. This leads to the necessity for a "morph... Read More

Clumpy galaxies in CANDELS. II. Physical properties of UV-bright clumps at 0.5 ≤ z < 3 (2018)
Journal Article
Guo, Y., Rafelski, M., Bell, E. F., Conselice, C. J., Dekel, A., Faber, S. M., …Wang, W. (2018). Clumpy galaxies in CANDELS. II. Physical properties of UV-bright clumps at 0.5 ≤ z < 3. Astrophysical Journal, 853(2), doi:10.3847/1538-4357/aaa018. ISSN 0004-637X

Studying giant star-forming clumps in distant galaxies is important to understand galaxy formation and evolution. At present, however, observers and theorists have not reached a consensus on whether the observed "clumps" in distant galaxies are the s... Read More

Scientific synergy between LSST and Euclid (2017)
