Schoerck, T., Christlieb, N., Cohen, J. G., Beers, T. C., Shectman, S., Thompson, I., ...
We determine the metallicity distribution function (MDF) of the Galactic halo by means of a sample of 1638 metal-poor stars selected from the Hamburg/ESO objective-prism survey (HES). The sample was...
An Update on the 0Z Project (2007)
Cohen, J. G., Christlieb, N., McWilliam, A., Shectman, S., Thompson, I.
We give an update on our 0Z Survey to find more extremely metal poor (EMP) stars with [Fe/H] < -3 dex through mining the database of the Hamburg/ESO Survey. We present the most extreme such stars we...
Soderberg, A. M., Nakar, E., Cenko, S. B., Cameron, P. B., Frail, D. A., Kulkarni, S. R., ...
We present detailed optical, near-infrared, and radio observations of the X-ray flash 050416a obtained with Palomar and Siding Springs Observatories as well as HST and the VLA, placing this event...
Results from the GMT Ground-Layer Experiment at the Magellan Telescopes (2006)
Athey, A., Shectman, S., Phillips, M., Thomas-Osip, J.
We present results from our two year study of ground-layer turbulence as seen through the 6.5-meter Magellan Telescopes at Las Campanas Observatory. The experiment consists of multiple, moderate...
The afterglow of GRB050709 and the nature of the short-hard gamma-ray bursts (2005)
Fox, D. B., Frail, D. A., Price, P. A., Kulkarni, S. R., Berger, E., Piran, T., ...
The final chapter in the long-standing mystery of the gamma-ray bursts (GRBs) centres on the origin of the short-hard class, suspected on theoretical grounds to result from the coalescence of neutron...
An HST Search for Supernovae Accompanying X-ray Flashes (2005)
Soderberg, A. M., Kulkarni, S. R., Fox, D. B., Berger, E., Price, P. A., Cenko, S. B., ...
We present the results from an Hubble Space Telescope/ACS search for supernovae associated with X-ray flashes 020903, 040701, 040812 and 040916. We find strong evidence that XRF 020903 (z=0.25) was...
Discovery of the CV ROTSE3 J015118.59-022300.1 (2002)
Smith, D. A., Akerlof, C., Ashley, M. C. B., Casperson, D., Gisler, G., Henden, A., ...
We report on the discovery of an outburst from a previously unknown high- latitude CV we designate ROTSE3 J015118.59-022300.1. The object was first detected on 2001 Oct 13.291 at...
The Universe on Very Large Scales: A View from the Las Campanas Redshift Survey (1999)
Tucker, D. L., Lin, H., Shectman, S.
The Las Campanas Redshift Survey (LCRS) is among the first galaxy redshift surveys to sample a reasonably fair volume of the local Universe. On the largest scales (>> 100/h Mpc), the galaxy...
