[1][2] With its second director, Martin A. Pomerantz, an Antarctic research program was developed along these lines and is maintained until today: Bartol scientists contribute to several Antarctic cosmic-ray projects, including ballon-borne cosmic-ray detectors such as ANITA, and ground-based experiments such as neutron monitors[3] and the IceCube Neutrino Observatory.

Consequently, the Bartol Research Institute is a member of several major international collaborations that run some of the leading experiments in this field, such as VERITAS, the Cherenkov Telescope Array, the Pierre Auger Observatory, and IceCube.

Among its members is William H. Matthaeus, the current director of the NASA Delaware Space Grant Consortium", who has made key contributions to the field including involvement in the Parker Solar Probe.

[5] Shortly before Norman Ness became the third Bartol Director, he was elected to the National Academy of Sciences for his seminal contributions to measuring planetary and interplanetary magnetic fields.

[15] The integration of the Bartol Research Institute into the Department of Physics and Astronomy at the University of Delaware was completed in the year 2005.
