MMT/AO 5 micron Imaging Constraints on the Existence of Giant Planets Orbiting Fomalhaut at ~13-40 AU

Matthew A. Kenworthy, Eric E. Mamajek, Philip M. Hinz +5

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) A…

Deep L' and M-band Imaging for Planets Around Vega and epsilon Eridani

A. N. Heinze, Philip M. Hinz, Matthew Kenworthy +2

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)…

A cryogenic liquid-mirror telescope on the moon to study the early universe

Roger Angel, Simon P. Worden, Ermanno F. Borra +9

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 in…

Enrichment and Pre-Heating in Intragroup Gas from Galactic Outflows

Romeel Davé, Benjamin D. Oppenheimer, Suresh Sivanandam

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 gal…

A photometric search for transients in galaxy clusters

D. J. Sand, D. Zaritsky, S. Herbert-Fort +2

We have begun a program to search for supernovae and other transients in the fields of galaxy clusters with the 2.3m Bok Telescope on Kitt Peak. We present our automated photometri…

First On-Sky High Contrast Imaging with an Apodizing Phase Plate

Matthew A. Kenworthy, Johanan L. Codona, Philip M. Hinz +3

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…

High Contrast L' Band Adaptive Optics Imaging to Detect Extrasolar Planets

Ari Heinze, Phil Hinz, Suresh Sivanandam +2

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…

Clio: a 3-5 micron AO planet-finding camera

S. Sivanandam, P. M. Hinz, A. N. Heinze +2

Clio is an adaptive-optics camera mounted on the 6.5 meter MMT optimized for diffraction-limited L' and M-band imaging over a ~15'' field. The instrument was designed from the grou…

Thermal Infrared Constraint to a Planetary Companion of Vega with the MMT Adaptive Optics System

Philip M. Hinz, A. N. Heinze, Suresh Sivanandam +5

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…
