(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 researcher is a star behind the cloud

A revolution in cloud computing is underway, and Ravi Sandhu believes it will be much bigger than the PC and Internet revolutions that have already changed the way we live. Sandhu, director of the UTSA Institute for Cyber Security, says UTSA is taking a leadership role in tackling three fundamental cloud technology problems: how to build and operate the cloud, how to use it profitably for diverse applications and how to keep it secure.

Sandhu, the Lutcher Brown Distinguished Chair in Cyber Security in the College of Sciences, and Ram Krishnan, assistant professor of electrical engineering in the UTSA College of Engineering, are funded by a $500,000 grant from the National Science Foundation to improve cloud security.

Did you know? Sandhu, a world-renowned cybersecurity expert, holds 30 patents, has authored more than 250 papers and been cited more than 30,000 times.
