Photometric Redshifts with the LSST II: The Impact of Near-Infrared and Near-Ultraviolet Photometry

The groundbreaking advances in cosmological astrophysics to be made by the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) all rely, at least in part, on accurate photometric redshift estimates for billions galaxies in our Universe. These…

Photometric Biases in Modern Surveys

Precise brightness measurements, or photometry, are essential for many areas of astronomy. DiRAC Postdoctoral Fellow Stephen Portillo, together with collaborators Joshua Speagle and Douglas Finkbeiner, published the  paper “Photometric Biases in Modern Surveys” which illustrates a measurement bias that is common…
