Cataloging Reflections by Kit Whitten, Carnegie Observatories Library Intern

It is commonly believed that when looking for valuable treasure, the best place to look is the attic—after all, works by Caravaggio, Van Gogh, Rembrandt, and Jackson Pollack have been discovered in attics—but not everyone thinks to look in the basement. Yet institutions like Carnegie Observatories often keep the best stuff in the basement.

The underground vault at the Observatories houses the nation’s second-largest, single-institution collection of astronomical glass plates, which are thin sheets of glass with an emulsion image of celestial bodies.  Photographic plates preceded plastic

Former Carnegie fellow and current trustee Sandy Faber has been selected to receive the 2018 American Philosophical Society’s Magellanic Premium Medal.  The medal is the nation’s oldest for scientific achievement. It was established in 1786. It is awarded from time to time “ to the author of the best discovery or most useful invention related to navigation, astronomy, or natural philosophy…”

Dr. Faber is the University of California, Santa Cruz, University Professor of Astronomy and Astrophysics and has been a Carnegie trustee since 1985.  After receiving a B.A. in physics from Swarthmore College, she pursued her Ph.D. in astronomy at Harvard, which she received in 1972. Much of

La Serena, Chile—Last week, scientists and staff from Carnegie’s Las Campanas Observatory volunteered for Astroday 2018 at a 170-year-old school in the nearby city of Las Serena, the Colegio Seminario Conciliar.

Organized by the Gemini Observatory, the daylong outreach event features activities including a planetarium, science projects, a 3-D movie, and night sky viewing. Several Chile-based astronomy facilities participated, both from the research and tourist sectors, all sharing the wonders of the universe with the community.

Since its inception in 2006, thousands of La Serena residents have participated in Astroday.

The recent discovery that the universe is expanding at an accelerating rate has profoundly affected physics. If the universe were gravity-dominated then it should be decelerating. These contrary results suggest a new form of “dark energy”—some kind of repulsive force—is driving the universe. To get a grasp of dark energy, it is extremely important that scientists get the most accurate measurements possible of Type Ia supernovae. These are specific types of exploring stars with exceptional luminosity that allow astronomers to determine distances and the acceleration rate at different distances. At the moment, the reality of the accelerating universe remains controversial because of

The Earthbound Planet Search Program has discovered hundreds of planets orbiting nearby stars using telescopes at Lick Observatory, Keck Observatory, the Anglo-Australian Observatory, Carnegie's Las Campanas Observatory, and the ESO Paranal Observatory.  Our multi-national team has been collecting data for 30 years, using the Precision Doppler technique.  Highlights of this program include the detection of five of the first six exoplanets, the first eccentric planet, the first multiple planet system, the first sub-Saturn mass planet, the first sub-Neptune mass planet, the first terrestrial mass planet, and the first transit planet.Over the course of 30 years we have improved the

The Carnegie Irvine Galaxy Survey is obtaining high-quality optical and near-infrared images of several hundred of the brightest galaxies in the southern hemisphere sky, at Carnegie’s Las Campanas Observatory to investigate the structural properties of galaxies.

Staff astronomer emeritus Eric Persson headed a group that develops and uses telescope instrumentation to exploit new near-infrared (IR) imaging array detectors. The team built a wide-field survey camera for the du Pont 2.5-meter telescope at Carnegie’s Las Campanas Observatory in Chile, and the first of two cameras for the Magellan Baade telescope. Magellan consortium astronomers use the Baade camera for various IR-imaging projects, while his group focuses on distant galaxies and supernovae.

Until recently, it was difficult to find large numbers of galaxies at near-IR wavelengths. But significant advances in the size of IR detector arrays have allowed the Persson group to survey

Leopoldo Infante became the director of the Las Campanas Observatory on July 31, 2017.

Since 2009, Infante has been the founder and director of the Centre for Astro-Engineering at the Chilean university. He joined PUC as an assistant professor in 1990 and has been a full professor since 2006. He was one of the creators of PUC’s Department of Astronomy and Astrophysics, and served as its director from 2000 to 2006. He also established the Chilean Astronomical Society (SOCHIAS) and served as its president from 2009 to 2010.

Infante received his B.Sc. in physics at PUC. He then acquired a MSc. and Ph.D. in physics and astronomy from the University of Victoria in Canada.

Guillermo Blanc wants to understand the processes by which galaxies form and evolve over the course of the history of the universe. He studies local galaxies in the “present day” universe as well as very distant and therefore older galaxies to observe the early epochs of galaxy evolution. Blanc conducts a series of research projects on the properties of young and distant galaxies, the large-scale structure of the universe, the nature of Dark Energy—the mysterious repulsive force, the process of star formation at galactic scales, and the measurement of chemical abundances in galaxies.

To conduct this work, he takes a multi-wavelength approach including observations in the UV,

Staff member Nick Konidaris joined Carnegie in October 2017. He works on a variety of new optical instrumentation projects in astronomy. He  recently began working on a new development platform for the 40-inch Swope telescope at Carnegie's Las Campanas Observatory. It is called the Rapid Response Swope Spectrograph and Imager (R2S2I). When operational, it will be a workhorse instrument and development platform.

Prior to Carnegie, he was director of product management at Kairos Aerospace in Mountain View, CA. Konidaris received a B.S. in physics from Carnegie Mellon University, and conducted coursework in electrical engineering before obtaining a Ph.D. in astrophysics from the
