Vegetation's Red Edge: A Possible Spectroscopic Biosignature of Extraterrestrial Plants
Sara Seager, Edwin L. Turner, Justin Schafer +1
Earth's deciduous plants have a sharp order-of-magnitude increase in leaf reflectance between approximately 700 and 750 nm wavelength. This strong reflectance of Earth's vegetation…
A Model of the Temporal Variability of Optical Light from Extrasolar Terrestrial Planets
Eric B. Ford, Sara Seager, Edwin L. Turner
The light scattered by an extrasolar Earth-like planet's surface and atmosphere will vary in intensity and color as the planet rotates; the resulting light curve will contain infor…
Microlensing results from APO monitoring of the double quasar Q0957+561A,B between 1995 and 1998
Joachim Wambsganss, Robert W. Schmidt, Wesley N. Colley +2
If the halo of the lensing galaxy 0957+561 is made of massive compact objects (MACHOs), they must affect the lightcurves of the quasar images Q0957+561 A and B differently. We sear…
A Model-Independent Photometric Redshift Estimator
Yun Wang, Neta Bahcall, Edwin L. Turner
We derive a simple empirical photometric redshift estimator using a training set of galaxies with multiband photometry and measured redshifts in the Hubble Deep Field (HDF). This e…
The Near-Infrared Galaxy Counts Anomaly: Local Underdensity or Strong Evolution?
L. A. Phillips, Edwin L. Turner
We analyze bright-end (K = 10 -17) galaxy counts from a number of near-infrared galaxy surveys. All studies available as of mid-1997, considered individually or collectively, show…
