I am an assistant professor and astronomer at the University of Denver. I study how massive stars interact with their environments, both before and after they explode as supernovae.
Lisa Randall to speak at DU
2013 March 27 — Harvard professor and renowned particle physicist Lisa Randall will speak at DU during the April APS meeting, 7 PM on April 15. Dr. Randall will present her lecture, entitled "Truth and Beauty, and Other Scientific Misconceptions," after accepting the Andrew Gemant Award from the American Institute of Physics. She will also sign copies of her books after the lecture.
The DU Department of Physics & Astronomy is sponsoring Dr. Randall's lecture, which will be free and open to the public. Our local chapter of the Society of Physics Students will present live physics demonstrations before and after the talk. Please join us for an evening of fascinating science! For more details, see our information page or contact me directly.
All eyes on Mintaka
2013 January 31 — My group has been invited to participate in a multiwavelength observing campaign focused on the massive binary star δ Ori (Mintaka, one of the stars in Orion's belt). We will contribute spectropolarimetric observations obtained with HPOL that will support recent X-ray spectra from Chandra and precision optical photometry from MOST. The aim is to better describe the characteristics of the clumpy mass loss occurring in this complex, eclipsing variable system.
We obtained one observation shortly before the Chandra data were taken, and will continue to monitor the system to characterize its polarized light curve.
