Tri Astraatmadja Joins DTM as Our First Thompson Postdoctoral Fellow

Tri Astraatmadja

Tri Astraatmadja comes to DTM as our first Thompson postdoctoral fellow, supported by gifts from Mr. David W. Thompson and the Thompson Family Fund.

While at DTM, Astraatmadja will be working with Alan Boss and Alycia Weinberger to improve the data analysis pipeline of the Carnegie Astrometric Planet Search(CAPS) project. The instrument, CAPSCam, has been taking data since 2007, and is designed to accurately measure the position of target stars relative to background stars.

Before coming to DTM, Astraatmadja was working as a postdoctoral researcher at the Max Planck Institute for Astronomy (MPIA) in Heidelberg, Germany, where he was a member of the Gaia astrometric satellite collaboration. Within Gaia, he was a part of the group responsible for extracting astrophysical parameters of all sources detected by the satellite. For stellar sources the interesting parameters for examples are temperatures, surface gravity, metallicity, and line-of-sight extinction by interstellar matter. In addition to these Gaia-related works, Astraatmadja also works with Coryn Bailer-Jones in investigating the estimation of distance using Gaia parallax.

Astraatmadja did his Ph.D. research at the National Institute for Subatomic Physics in Amsterdam, Netherlands, as well as the Physics Department of Leiden University. His Ph.D. project was focused on the detection of very high-energy gamma rays using neutrino telescopes, specifically the ANTARES undersea neutrino telescope, in which he was a member of the collaboration. For this dissertation Astraatmadja won the 2015 Global Neutrino Network (GNN) dissertation prize.

Please join us in welcoming Astraatmadja as our newest fellow.
