Ground-based Measurements of Sources in the AFGL Infrared Sky Survey. (2002)
Rudy,Richard J., Gosnell,Timothy R., Willner,S. P.
This report contains ground-based observations of 271 objects detected in the AFGL infrared sky survey, falling between 40 min. and 60 min. of each hour of right ascension and +60 deg and -30 deg of...
Lada, Charles J., Muench, August A., Haisch Jr., Karl E., Lada, Elizabeth A., Alves, Joao F., Tollestrup, Eric V., ...
We report the results of a sensitive near-infrared JHKL imaging survey of the Trapezium cluster in Orion. We use the JHKL colors to obtain a census of infrared excess stars in the cluster. Of (391)...
Wide-field J- and K-band galaxy counts in the ELAIS fields (2000)
Vaisanen, P., Tollestrup, E. V., Willner, S. P., Cohen, M.
New near-infrared galaxy counts in the J and K bands are presented over a total area of 0.70 and 0.97 degrees^2, respectively. The limiting magnitudes of the deepest regions are 19.5 in J and 18.0 in...
The Infrared Array Camera (IRAC) for the Space Infrared Telescope Facility (SIRTF) (1998)
G.G. Fazio, J.L. Hora, S.P. Willner, Pipher B
The Space Infrared Telescope Facility (SIRTF) contains three focal plane instruments, one of which is the Infrared Array Camera (IRAC). IRAC is a four-channel camera that provides simultaneous 5.12...
Power Law Decays in the Optical Counterparts of GRB 970228 and GRB970508 (1997)
Garcia, M. R., Callanan, P. J., Moraru, D., McClintock, J. E., Tollestrup, E., Willner, S. P., ...
We report on R_c and K band observations of the optical counterpart to GRB 970508 with the Fred Lawrence Whipple Observatory (FLWO) 1.2m telescope. Eleven R_c-band observations were obtained on 1997...
The Infrared Tully-Fisher Relation in the Ursa-Major Cluster (1993)
Peletier, R. F., Willner, S. P.
We present new magnitudes derived from 1.65 micron images for 23 galaxies in the Ursa Major cluster. Magnitudes now exist for all but one spiral meeting our criteria for cluster membership and having...
Interstellar absorption lines toward NGC 2264 and AFGL 2591: Abundances of H2, H+3 and CO (1990)
Black, J.H., Dishoeck, E.F. Van, Willner, S.P., Woods, R.C.
Interstellar absorption-line spectroscopy of NGC 2264 is reported which shows that the CO molecule has a column density of 5 x 10 to the 18th/sq cm and a rotational excitation temperature of 28 K. A...
