Unveiling a Black Hole at the Center of Our Galaxy (2009)
More than a quarter century ago, it was suggested that galaxies such as our own Milky Way may harbor massive, though possibly dormant, central black holes. Definitive proof, for or against, the...
Beichman, Charles, Baraffe, Isabelle, Crockett, Christopher, Dodson-Robinson, Sarah, Fortney, Jonathan, Ghez, Andrea, ...
Despite the revolution in our knowledge resulting from the detection of planets around mature stars, we know almost nothing about planets orbiting young stars because rapid rotation and active...
Tanner, Angelle, Beichman, Charles, Akeson, Rachel, Ghez, Andrea, Grankin, Konstantin N., Herbst, William, ...
We present a review of precursor observing programs for the SIM PlanetQuest Key project devoted to detecting Jupiter mass planets around young stars. In order to ensure that the stars in the sample...
Late-time observations of SN2006gy: Still Going Strong (2008)
Smith, Nathan, Foley, Ryan J., Bloom, Joshua S., Li, Weidong, Filippenko, Alexei V., Gavazzi, Raphael, ...
Owing to its extremely high luminosity and long duration, SN2006gy radiated more energy in visual light than any other known SN. Two hypotheses to explain its high luminosity -- that it was powered...

Pinwheels in the Quintuplet Cluster (2006)
Tuthill, Peter, Monnier, John, Tanner, Angelle, Figer, Donald, Ghez, Andrea, Danchi, William
The five enigmatic Cocoon stars after which the Quintuplet cluster was christened have puzzled astronomers since their discovery. Their extraordinary cool, featureless thermal spectra have been...
We present the results of a magnitude limited (K
Non coeval young multiple systems? On the pairing of protostars and T Tauri stars (2003)
Duchene, Gaspard, Ghez, Andrea, McCabe, Caer
We summarize here the observed properties of ``infrared companions'' to T Tauri stars and argue that their observational properties are identical to those of Class I sources. They may therefore be...
