A Surprisingly High Pair Fraction for Extremely Massive Galaxies at z ~ 3 in the GOODS NICMOS Survey
Asa F. L. Bluck, Christopher J. Conselice, Rychard J. Bouwens +4
We calculate the major pair fraction and derive the major merger fraction and rate for 82 massive () galaxies at utilising deep HST NICMOS d…
New Observations and a Possible Detection of Parameter Variations in the Transits of Gliese 436b
Jeffrey L. Coughlin, Guy S. Stringfellow, Andrew C. Becker +3
We present ground-based observations of the transiting Neptune-mass planet Gl 436b obtained with the 3.5-meter telescope at Apache Point Observatory and other supporting telescopes…
An Infrared High Proper Motion Survey Using 2MASS and SDSS: Discovery of M, L and T Dwarfs
Scott S. Sheppard, Michael C. Cushing
A search of the Two Micron All Sky Survey and Sloan Digital Sky Survey reveals 36 previously unknown high proper motion objects with J<17. Their red-optical colors indicate that 27…
Lessons Learned from Sloan Digital Sky Survey Operations
S. J. Kleinman, J. E. Gunn, B. Boroski +12
Astronomy is changing. Large projects, large collaborations, and large budgets are becoming the norm. The Sloan Digital Sky Survey (SDSS) is one example of this new astronomy, and…
Photometric variability of WC9 stars
R. Fahed, A. F. J. Moffat, A. Z. Bonanos
Do some Wolf-Rayet stars owe their strong winds to something else besides radiation pressure? The answer to this question is still not entirely obvious, especially in certain Wolf-…
New period-luminosity and period-color relations of classical Cepheids: III. Cepheids in SMC
A. Sandage, G. A. Tammann, B. Reindl
The photometric data for 460 classical, fundamental-mode Cepheids in the SMC with log P > 0.4 measured by Udalski et al. have been analyzed for their P-C and P-L relations, and for…
