Alekzander Kosakowski Joins Group as Postdoc

We are thrilled that Dr. Alekzander Kosakowski has joined our group as a postdoctoral research associate. Alekzander is an observational astronomer specializing in studies of merging white dwarf binaries as gravitational wave sources and progenitors to stably accreting binaries, massive single white dwarfs, and supernovae. He uses data from large ground-based telescopes to characterize binaries through detailed photometric and spectroscopic analyses. His work makes use of archival data sets from time domain surveys, such as ZTF and TESS, to identify white dwarf systems which show periodic photometric variability on timescales ranging from minutes to hours. Alekzander is the project lead for the “ELM Survey South,” a spectroscopic survey designed to identify and characterize Extremely Low Mass white dwarfs in the southern sky.
