According to this model, the only difference between the stellar populations in the intermediate redshift E/SO galaxies is an age difference equal to the look-back time to the intermediate redshift galaxies.

CCD detectors were not yet being used on astronomical instruments to collect data from the sky, astronomers were still struggling with low-sensitivity photographic plates, and the most powehl computers were as big as a room and didn t have the capabilities equivalent to any of today s laptops. However, even at that time, astronomers knew that bigger galaxies in the universe were also chemically 232
more evolved than smaller galaxies. The origin of what is now called the mass- metallicity relation in galaxies is still controversial. After more than three decades of research and observations, theories dealing with this phenomenon still lack the information coming from an important fundamental parameter: cosmic time. We don’t know whether the mass-metallicity relation was in place in the past history of the universe or how different it was in the past from what is observed today. More precisely, we didn t even have a clue about these issues until now. A recent study based on data taken at the Gemini North telescope shows for the first time that the mass-metallicity relation in galaxies already existed at redshift z = 0.7 (seven billion years ago), at a time when the universe was about half of its present age. Not only was the relation clearly reflected in the galaxies as they existed at that time, but it was also different from the one we see in the nearby (and more recent) universe. The data used for this study were taken as part of the Gemini Deep Deep Survey (GDDS). The project benefitted from a number of factors that, when combined, allowed this dimcult discovery to be made. First, faint targets were efficiently observed thanks to the fantastic capabilities of the Gemini Multi-Object Spectrograph (GMOS), working in nod-and-shume mode. Second, the GDDS galaxies were combined with a sample of brighter galaxies observed as part of the Canada-France Redshift Survey (CFRS), doubling the size of the initial sample. Third, optical and near-infrared photometry of the galaxy integrated light (from the Las Campanas Redshift Survey and the CFRS) allowed stellar mass measurements for the sample, through extensive modeling of the stellar population. As a result, the 56 galaxies in the sample cover a very large range in stellar mass and metallicity (a factor of 400 for mass and almost 10 for metallicity).

New data from the Gemini Near-Infrared Spectrograph (GNIRS) has revealed surprising information about what lies at the center of this galaxy. Its optical appearance is striking, with a rich complex disk of dust and gas that cuts across the round body of this elliptical galaxy (Figure I). It was also one of the first astronomical radio sources ever detected. More than just historically interesting however, Centaurus A is an important object for our understanding of central black holes in galaxies, galaxy mergers, active galactic nucleus activity, and the relationships among these components during galaxy formation and evolution. As galaxies form and grow, their different components interact to assemble galaxies as we see them around us today. These interactions are understood at a wide range of levels, from quite well to not at all. One link that appears clear is the relationship between black hole mass and galaxy kinematic properties (how the stars in the galaxy are moving as a whole). This relationship has been seen in ever-growing samples of nearby well- studied galaxies and has been found reliable and to have small scatter. In order to understand the underlying reasons for this relationship, we need to study galaxies that have more diverse characteristics. Current samples of galaxies are not very heterogeneous; these well- studied galaxies have been so thoroughly examined because they lend themselves well to normal optical techniques. These techniques are not successful when applied to a more difficult type of galaxy, such as Centaurus A, which is heavily obscured by dust.

The observatory counts on programmers and information technology experts to deliver data to the right places at the right times. This includes everything from keeping the networks running to maintaining an active World Wide Web presence for the observatory. Jason Kalawe is the man behind the Gemini web portal, and beyond that, the go-to person for server administration and much more. He is part of the observatory s Information Systems Group and his official title is Web Master. However, as he likes to point out, his job goes far beyond keeping Gemini s Web page up and running.
