SDSS-III: MASSIVE SPECTROSCOPIC SURVEYS OF THE DISTANT UNIVERSE, THE MILKY WAY, AND EXTRA-SOLAR PLANETARY SYSTEMS
- D. Eisenstein, D. Weinberg, +237 authors B. Zhao
- Physics
- 1 December 2007
Building on the legacy of the Sloan Digital Sky Survey (SDSS-I and II), SDSS-III is a program of four spectroscopic surveys on three scientific themes: dark energy and cosmological parameters, the… Expand
Black Hole Masses and Eddington Ratios at 0.3 < z < 4
- J. Kollmeier, C. Onken, +12 authors Jpl
- Physics
- 30 August 2005
We study the distribution of Eddington luminosity ratios, Lbol/LEdd, of active galactic nuclei (AGNs) discovered in the AGN and Galaxy Evolution Survey (AGES). We combine Hβ, Mg II, and C IV line… Expand
REDDENING AND EXTINCTION TOWARD THE GALACTIC BULGE FROM OGLE-III: THE INNER MILKY WAY'S RV ∼ 2.5 EXTINCTION CURVE*
- D. Nataf, A. Gould, +11 authors R. Poleski
- Physics
- 6 August 2012
We combine VI photometry from OGLE-III with VISTA Variables in The Via Lactea survey and Two Micron All Sky Survey measurements of E(J ? Ks ) to resolve the longstanding problem of the non-standard… Expand
Discovering Planetary Systems through Gravitational Microlenses
Planetary systems of Galactic disk stars can be detected as microlenses of stars in the Galactic bulge. Planets in a solar-like system positioned half-way to the Galactic center should leave a… Expand
Resonant Enhancements In WIMP Capture By The Earth
- A. Gould
- 1987
The exact formulae for the capture of WIMPS (weakly interacting massive particles) by a massive body are derived. Capture by the earth is found to be significantly enhanced whenever the WIMP mass is… Expand

M Dwarfs from Hubble Space Telescope Star Counts. III. The Groth Strip
- A. Gould, J. Bahcall, C. Flynn
- Physics
- 20 November 1996
We analyze the disk M dwarfs found in 31 new fields observed with the Wide Field Camera 2 (WFC2) on the Hubble Space Telescope, together with the sample previously analyzed from 22 WFC2 fields and… Expand
A giant planet undergoing extreme-ultraviolet irradiation by its hot massive-star host
- B. Gaudi, K. Stassun, +57 authors Patricia Trueblood
- Physics, Medicine
- Nature
- 1 June 2017
The amount of ultraviolet irradiation and ablation experienced by a planet depends strongly on the temperature of its host star. Of the thousands of extrasolar planets now known, only six have been… Expand
A CLUSTER OF BLACK HOLES AT THE GALACTIC CENTER
- J. Miralda-Escud'e, A. Gould
- Physics
- 17 March 2000
If the stellar population of the bulge contains black holes formed in the final core collapse of ordinary stars with M 30 M☉, then about 25,000 stellar mass black holes should have migrated by… Expand
Stellar Contribution to the Galactic Bulge Microlensing Optical Depth
We estimate the optical depth to self-lensing by stars in the Galactic bulge using the Hubble Space Telescope star counts of Holtzman et al. and Zoccali et al. as extrapolated by Gould into the brown… Expand
Imaging the Forest of Lyman Limit Systems
- A. Gould, D. Weinberg
- Physics
- 1 September 1996
We show that it is now possible to image optically thick $\lya$ clouds in fluorescent $\lya$ emission with a relatively long ($\sim 20 $hr) integration on a large ($\sim 10 $m) telescope. For a broad… Expand
