Subaru Seminars



This Month






Site Map

The Subaru Seminar is usually held in Room 104 of the Hilo Base Facility, adjacent to the main lobby. Everyone is welcome to attend. If you are interested in giving a seminar, please contact Subaru seminar organizers (Tae-Soo Pyo, Sherry Yeh, Nagayoshi Ohashi) by email : (please change"_at" to @).

" About VIRUSes, Fibers and Galaxies "

Maximilian Fabricius

(Max Planck Institute for Extraterrestrial Physics)

VIRUS-W is a fiber based optical IFU spectrograph that we constructed specifically to study the dynamical properties of kinematically cold stellar systems such as disks and dwarf galaxies. The instrument is a spin-off of the main survey instrument for the Hobby-Eberly Dark Energy Experiment (HETDEX). I will introduce the instrument itself and also talk about its heritage. Its high spectral resolution positions VIRUS-W uniquely to detect low level rotations of stellar systems and to study the actual fine structure of line-of-sight velocity distributions. I will discuss a few recent science results such as the genuine kinematic decomposition of the spiral galaxy NGC7217 and the detection of ubiquitous central rotation of Milky Way globular clusters.

Seminars are also held at JAC, CFHT, and IfA.
