Four years of optical turbulence monitoring at the Cerro Tololo Inter-American Observatory (CTIO)
S. G. Els, M. Schoeck, E. Bustos +7
The optical turbulence conditions as measured between 2004 until end of 2008 above Cerro Tololo, their seasonal as well as nocturnal behavior are presented. A comparison with the M…
Thirty Meter Telescope Site Testing VI: Turbulence Profiles
S. G. Els, T. Travouillon, M. Schoeck +5
The results on the vertical distribution of optical turbulence above the five mountains which were investigated by the site testing for the Thirty Meter Telescope (TMT) are reporte…
Thirty Meter Telescope Site Testing I: Overview
M. Schoeck, S. Els, R. Riddle +15
As part of the conceptual and preliminary design processes of the Thirty Meter Telescope (TMT), the TMT site testing team has spent the last five years measuring the atmospheric pr…
Wide-Field Survey of Globular Clusters in M31. I. A Catalog of New Clusters
Sang Chul Kim, Myung Gyoon Lee, Doug Geisler +6
We present the result of a wide-field survey of globular clusters (GCs) in M31 covering a 3deg x 3deg field c. We have searched for GCs on CCD images taken with Washington CMT1 fil…
Exploring Halo Substructure with Giant Stars III: First Results from the Grid Giant Star Survey and Discovery of a Possible Nearby Sagittarius Tidal Structure in Virgo
A. Kundu, S. R. Majewski, J. Rhee +14
We describe first results of a spectroscopic probe of selected fields from the Grid Giant Star Survey. Multifiber spectroscopy of several hundred stars in a strip of eleven fields…
The Type Ia Supernova 1999aw: a Probable 1999aa-like Event In a Low-Luminosity Host Galaxy
L. -G. Strolger, R. C. Smith, N. B. Suntzeff +39
SN 1999aw was discovered during the first campaign of the Nearby Galaxies Supernova Search (NGSS) project. This luminous, slow-declining (Delta m_{15} (B) = 0.81 \pm 0.03) Type Ia…
New CCD Survey of Globular Clusters in M31
Myung Gyoon Lee, Sang Chul Kim, Doug Geisler +3
We present a progress report of our wide field CCD survey of globular clusters in M31. We have covered 3 deg X 3 deg area centered on M31, using the KPNO 0.9m and Washington CMT1 f…
Washington Photometry of New Globular Clusters in M31
Sang Chul Kim, Myung Gyoon Lee, Doug Geisler +3
We present a progress report on Washington photometry of several hundred new globular cluster (GC) candidates in M31 which were recently found from our new CCD survey of GCs. Washi…
