Texas Astronomy Undergraduate Research Symposium 2014
The University of Texas at Austin Department of Astronomy will be hosting the fourth annual Texas Astronomy Undergraduate Research Symposium on Friday, September 19, 2014. Undergraduates from central Texas are invited to give 10 minute talks on their astronomy research, based on either their summer or academic year research projects. Other students, postdocs, and faculty are invited to attend and hear about the first-rate research being done by these undergraduates.
The Inner Regions of Quasars
The symposium The Inner Regions of Quasars will be held Friday, September 12th through Sunday, September 14th, 2014 on the 15th floor of Robert Lee Moore Hall (RLM) [map] on the campus of The University of Texas at Austin, to celebrate the work and career of Dr. Beverley Wills. Bev has been one of the pioneers in observing and interpreting the broad emission lines in all types of AGNs. Her enthusiasm and dedication inspired a generation of researchers in the field. This meeting celebrates Bev's contributions (many with Derek Wills) by presenting new results and by reviewing what has been achieved recently in this area of research.

HETDEX Update: Tracking Sphere
Mechanical Engineer John Good was in West Texas in late July to run point tests with HET's new tracker. The tracker sits 13 meters above the stationary primary mirror array, and moves within six axes (hexapod), to track stars. The image above defines the contact lens shaped plane along which the tracker must move to both track a star and maintain focus. These plotted, six axis measurements are accurate enough to quantify the deflection of the HET frame as the tracker assembly moves. The 20-ton, automated tracker will routinely traverse the focal sphere with a precision of a few microns, about 1/10th the diameter of a human hair.

Astronomy Undergraduates Earn Recognition
With programs like the Freshman Research Initiative, UT Astronomy continues to develop as a leading program for high achieving undergraduates, who participate directly in research and publication with scientists and faculty.

Henize Scholar; Mark Moore, Phi Beta Kappa; Amanda Turbyfill, Phi Beta Kappa; Sae Saito (not pictured), Eva Stevenson Woods Endowed Presidential Scholarship.
Revolutionary IGRINS enters engineering runs
McDonald Observatory's newest instrument, the Immersion Grating Infrared Spectrograph (IGRINS), began engineering runs in March. It will increase the spectral range, the range of instantaneous collectable wavelengths, 30x over the premier CRyogenic high-resolution InfraRed Echelle Spectrograph (CRIRES) at the European Southern Observatory's Very Large Telescope (VLT). IGRINS will have the ability to better penetrate dust obscured regions where stars and planets form, and will be used to find and characterize extrasolar planets. IGRINS will be available to observers as a PI instrument in Fall 2014.

Assembly and alignment of VIRUS spectrographs
The Hobby-Eberly Telescope in West Texas, is clearing room for the pending arrival of the first of 150 VIRUS spectrographs, undergoing assembly and alignment in Austin. Top left: units house optics and electronics in a vacuum. Top right: completed and aligned VIRUS pairs begin to fill a rack. Bottom right: optical fiber feeds the pairs during alignment, as mirrors and electronics are calibrated. Alignment alone requires about two days per pair. Bottom left: Trent Peterson and undergraduate Ingrid Johnson describe the demanding assembly. Learn more at HET Blog and HETDEX: Illuminating the Darkness.
Dr. Robert C. Kennicutt, Jr.
Public Lecture: The Hidden Universe Revealed
10 February 2014
Dr. Robert C. Kennicutt, Jr., Plumian Professor of Astronomy and Experimental Philosophy at the Institute of Astronomy, University of Cambridge, will deliver the public lecture, "The Hidden Universe Revealed," Wednesday, February 19, 2014 at 4:00 PM, in CPE 2.208 on The University of Texas at Austin campus. Dr. Kennicutt will discuss completely new classes of objects and phenomenon revealed by international space telescopes observing in the infrared and terahertz, regions of the electromagnetic spectrum previously hidden from telescopes. Dr. Kennicutt is the 17th recipient of the Antoinette de Vaucouleurs Memorial Lectureship, recognizing a lifetime of outstanding contribution to Astronomy.
