Kenworthy, Matthew A., Mamajek, Eric E., Hinz, Philip M., Meyer, Michael R., Heinze, Aren N., Miller, Douglas L., ...
A candidate < 3 Jupiter mass, extrasolar planet was recently imaged by Kalas et al. (2008) using HST/ACS at 12.7" (96 AU) separation from the nearby (d = 7.7 pc) young (~200 Myr) A2V star Fomalhaut....
The Enrichment of the Intracluster Medium (2008)
Sivanandam, Suresh, Zabludoff, Ann I., Zaritsky, Dennis, Gonzalez, Anthony H., Kelson, Dan D.
To determine the relative contributions of galactic and intracluster stars to the enrichment of the intracluster medium (ICM), we present X-ray surface brightness, temperature, and Fe abundance...
Deep L' and M-band Imaging for Planets Around Vega and epsilon Eridani (2008)
Heinze, A. N., Hinz, Philip M., Kenworthy, Matthew, Miller, Douglas, Sivanandam, Suresh
We have obtained deep Adaptive Optics (AO) images of Vega and epsilon Eri to search for planetary-mass companions. We observed at the MMT in the L' (3.8 micron) and M (4.8 micron) bands using Clio, a...
A cryogenic liquid-mirror telescope on the moon to study the early universe (2008)
Angel, Roger, Worden, Simon P., Borra, Ermanno F., Eisenstein, Daniel J., Foing, Bernard, Hickson, Paul, ...
We have studied the feasibility and scientific potential of zenith observing liquid mirror telescopes having 20 to 100 m diameters located on the moon. They would carry out deep infrared surveys to...
Enrichment and Pre-Heating in Intragroup Gas from Galactic Outflows (2008)
Davé, Romeel, Oppenheimer, Benjamin D., Sivanandam, Suresh
We examine metal and entropy content in galaxy groups having T_X~0.5-2 keV in cosmological hydrodynamic simulations. Our simulations include a well-constrained prescription for galactic outflows...
First On-Sky High Contrast Imaging with an Apodizing Phase Plate (2007)
Kenworthy, Matthew A., Codona, Johanan L., Hinz, Philip M., Angel, J. Roger P., Heinze, Ari, Sivanandam, Suresh
We present the first astronomical observations obtained with an Apodizing Phase Plate (APP). The plate is designed to suppress the stellar diffraction pattern by 5 magnitudes from 2-9 lambda/D over a...
High Contrast L' Band Adaptive Optics Imaging to Detect Extrasolar Planets (2006)
Heinze, Ari, Hinz, Phil, Sivanandam, Suresh, Apai, Daniel, Meyer, Michael
We are carrying out a survey to search for giant extrasolar planets around nearby, moderate-age stars in the mid-infrared L' and M bands (3.8 and 4.8 microns, respectively), using the Clio camera...
Hinz, Philip M., Heinze, A. N., Sivanandam, Suresh, Miller, Douglas L., Kenworthy, Matthew A., Brusa, Guido, ...
Vega may have a massive companion in a wide orbit, as evidenced by structure in its cold dust debris. We have tested this hypothesis by direct imaging with adaptive optics in the M band. The...
