Desert sky may yield answers
Daily Texan feature by Hudson Lockett
26 October 2009
Far above the desert landscape of West Texas, the Milky Way dominated the night sky. Six astronomers huddled around a cluster of glowing monitors, wrapping up a six-day
test run for a $34 million experiment that will keep the McDonald Observatory's largest telescope busy for three years, probing
the mysteries of dark energy. "There's a lot riding on this," said principal investigator Gary Hill early Sunday morning.
The final version of the Hobby-Eberly Telescope Dark Energy Experiment will measure the effect of dark energy on the universe by
surveying 100 million galaxies, making the largest-ever map of the universe in the process.
Texas Cosmology Network Meeting 2009 Begins Thursday, October 29 on the Austin Campus
26 October 2009
Cosmologists from Texas research institutions will meet Thursday and Friday, October 29 & 30, at the
AT&T Conference Center [map],
on the Austin campus of The University of Texas, for the second Texas Cosmology Network Meeting. A new Cosmology
program at Texas A&M was joined earlier this year by the opening of the Texas Cosmology Center in Austin.
Participants from UT Dallas, Baylor, Southern Methodist University, and the University of Houston will consider four broad focus areas: the early
universe (inflation), dark energy, dark matter and structure formation in the universe. The meeting is organized by the Texas Cosmology Center,
which is supported by The University of Texas at Austin, the College of Natural Sciences, the Department of Astronomy, Department of Physics,
and the McDonald Observatory.
2009 Antoinette de Vaucouleurs Lectureship Honors Russian Astronomer Rashid Sunyaev
22 October 2009
Awarded each year to an outstanding astronomer for a lifetime of dedication to astronomy,
the 2009 Antoinette de Vaucouleurs Lectureship honors the distinguished Russian astrophysicist Rashid Alievich Sunyaev (translit.-"Syunyaev").
Among the essential tools of modern astrophysics, Dr. Sunyaev's work includes the standard model of disk accretion
onto black holes, and the Sunyaev-Zel’dovich (SZ) effect, the scattering interaction of low energy Cosmic Microwave Background photons
with high energy photons found in the gas associated with galaxy clusters. The SZ effect opened the possibility of determining fundamental
cosmological parameters, the nature of density fluctuations in the early universe, the role of dark energy, and of measuring the hubble constant.
A highlight of award events will be the public lecture by Dr. Sunyaev, "The Richness and Beauty of the Physics of Cosmological
Recombination," Tuesday, October 27 at 7:00 PM in ACES 2.302.
Third Biennial Frank N. Bash Symposium, New Horizons in Astronomy, Begins Oct. 18
12 October 2009
The University of Texas Department of Astronomy and McDonald Observatory will be hosting the third biennial Frank N. Bash
Symposium on the topic of New Horizons in Astronomy, October 18-20, 2009 in the Avaya Auditorium, ACES 2.302,
on the Austin campus [map] .
The meeting brings together young researchers at the cutting edge of astronomy and astrophysics, to promote the exchange of
research ideas and visions for the future of astronomy. This year's meeting will include talks on cosmology, high energy astrophysics,
instrumentation, planet formation and more. The symposium is made possible by the contributions of The University of Texas at
Austin McDonald Observatory and Department of Astronomy Board of Visitors.
University of Texas Planetary Science Symposium Brings Together Researchers Across Disciplines
25 September 2009
Geologists, Aerospace Engineers, and Astronomers are among University of Texas researchers meeting
Friday, October 2, in the Avaya Auditorium, on the Austin campus, for the University of Texas Planetary Science Symposium. The meeting is
designed to introduce planetary scientists to one another, and to help foster new, interdisciplinary collaborations, courses and seminars.
An overfull schedule of 27 speakers will feature short talks on current research in Solar System Exploration and Techniques, Planet Formation and Evolution,
AstroGeoBiology, and Extrasolar Planets. The meeting is co-sponsored by The University of Texas at Austin Jackson School of Geosciences
and Department of Astronomy.

Joyce Byun, Krista Smith, Andy Liao and Aditi Raye Allen Win 2009 Undergraduate Awards
15 April 2009
The 2009 Outstanding Senior award, for overall performance (grades, research,
and service) to a graduating senior, has been awarded to Joyce Byun. For excellent overall performance
to a current or entering senior, Krista Smith has won the Board of Visitors scholarship. The Karl G. Henize endowed scholarship for
excellent academic performance in the 2nd year and beyond, has been jointly awarded to Andy Liao and Aditi Raye Allen. Prize winners are selected
each year by the Undergraduate Studies Executive Committee, following a call for nominations.
HETDEX Workshop to be held February 17-18
11 February 2009
The HETDEX Workshop
will be held Tuesday and Wednesday, February 17-18 at the Union Building (UNB)
on the campus of The University of Texas at Austin. New instruments and upgrades to the Hobby-Eberly Telescope are currently under way for the Hobby-Eberly
Telescope Dark Energy Experiment (HETDEX). The new capablities will create opportunities to probe important questions in astrophysics outside of the
primary objective of dark energy. Astronomers and engineers from participating HETDEX institutions will develop science cases to determine whether and
how current design plans might
be adjusted to take advantage of the new possibilities.
Public Lecture: Frontiers in Cosmology
30 January 2009
Dr. Eiichiro Komatsu, Assoc. Professor and Director of the Texas Cosmology Center, will present the public lecture "Frontiers in Cosmology,"
Saturday, February 7, at 1:00PM, in the Avaya Auditorium
ACE(S) 2.302 [map].
Dr. Komatsu will discuss both the astounding advances of the last decadequantifying the age, energy and matter of the Universeand the new, daunting
questions: What is Dark Matter and Dark Energy? What powered the Big Bang? Dr. Komatsu is a member of NASA's WMAP science team,
and a contributor to HETDEX, the Hobby-Eberly Telescope Dark Energy Experiment. The Great Lectures in Astronomy public series is sponsored by the The University of Texas at Austin
McDonald Observatory and Department of Astronomy Board of Visitors.

7 January 2009
The Second GMT High Resolution Spectroscopy Workshop will be held Friday and Saturday, January 16-17, in
ACE(S) 2.402 [map],

infrared spectroscopic instruments for the Giant Magellan Telescope (GMT). Scheduled for completion around 2017 at Las Campanas, Chile,
the 24.5-meter GMT will be the largest telescope ever built, producing images exceeding the resolution of Hubble Space Telescope. Astronomers
and instrument builders from 11 institutions on 3 continents are scheduled to attend.
