(Sept. 6, 2013) -- In July, the biggest optical/infrared telescope in the world was put in the hands of UTSA astronomers. For a week, two graduate students, Laura McMaster and Lindsay Fuller, and post-doctoral researcher Enrique Lopez-Rodriguez from the UTSA Department of Physics and Astronomy performed astronomical observations at the 10.4-meter Gran Telescopio Canarias (GTC) at La Palma in the Canary Islands, Spain.

Their goal was to observe the central regions of active galaxies that have a supermassive black hole at their center to advance their research about the structure and evolution of the objects.

The GTC is at the top of La Palma, one of the steepest islands in the world at 7,438 feet above sea level. At that altitude, the clouds are almost always below the telescope allowing for stable and clear skies. These conditions are excellent for using the telescope's infrared instrument called CanariCam. UTSA Assistant Professor Christopher Packham was one of the lead scientists in its development.

"Since relatively few 10-meter class telescopes exist, it is essential for students to travel there in order to train and collect data. This will be only one of many observing trips for them," said Lopez-Rodriguez.

McMaster and Fuller were instructed in how to perform astronomical observations by Lopez-Rodriguez and the GTC support astronomers. For the students, it was a quick introduction to the operation of scientific equipment and data analysis. "While there, we were able to observe the center of the Milky Way as well as several other distant galaxies," McMaster said.

Observations in infrared light, a form of light with a longer wavelength than visible light, are used by astronomers to better study dusty areas in galaxies. In the infrared, the dusty clouds appear bright, instead of dark and obscure as they do in visible light.

The trip was not just an observational training for the students but also an introduction to the collaborative format that the field of astronomy encourages. By creating partnerships, UTSA has the ability to enhance its scientific productivity using world-class facilities.

"The trip was literally on-the-job training, which just happened to be at the largest optical-infrared facility available in the world," said McMaster.

UTSA makes the grade with a strong core curriculum

UTSA prides itself on giving students a well-rounded education. Combining a top-tier academic program with opportunities for personal growth prepares students to compete in a global economy. And that's not all. They learn to be informed and engaged citizens as well. At the heart of that academic program is an award-winning core curriculum.

For four consecutive years, UTSA has received an A-rating from the American Council of Trustees and Alumni for the caliber of its core curriculum. According to ACTA, UTSA requires its students to take six of the seven courses deemed "crucial" to a well-rounded education: composition, literature, U.S. government or history, economics, mathematics and science. Only a handful of other institutions in the U.S. are giving students these tools, which are needed to succeed in careers and the community.

Did you know? UTSA is one of only three Texas institutions and 23 in the United States to receive the highest rating for its core curriculum in the 2014-2015 edition of the ACTA's "What Will They Learn?" report.
