Noise and bias in square-root compression schemes (2009)
Bernstein, Gary M., Bebek, Chris, Rhodes, Jason, Stoughton, Chris, Vanderveld, Ali, Yeh, Penshu
We investigate data compression schemes for proposed all-sky diffraction-limited visible/NIR sky surveys aimed at the dark energy problem. We show that lossy square-root compression to 1 bit of noise...
Improved Constraints on the Gravitational Lens Q0957+561. II. Strong Lensing (2009)
Fadely, Ross, Keeton, Charles R., Nakajima, Reiko, Bernstein, Gary M.
We present a detailed strong lensing analysis of an HST/ACS legacy dataset for the first gravitational lens, Q0957+561. With deep imaging we identify 24 new strongly lensed features, which we use to...
The cosmology dependence of weak lensing cluster counts (2008)
Marian, Laura, Smith, Robert E., Bernstein, Gary M.
We present the main results of a numerical study of weak lensing cluster counting. We examine the scaling with cosmology of the projected-density-peak mass function. Our main conclusion is that the...
Comprehensive Two-Point Analyses of Weak Gravitational Lensing Surveys (2008)
We present a framework for analyzing weak gravitational lensing survey data, including lensing and source-density observables, plus spectroscopic redshift calibration data. All two-point observables...
Multipole Formulae for Gravitational Lensing Shear and Flexion (2008)
Bernstein, Gary M., Nakajima, Reiko
The gravitational lensing equations for convergence, potential, shear, and flexion are simple in polar coordinates and separate under a multipole expansion once the shear and flexion spinors are...
THE QUADRUPLE GRAVITATIONAL LENS PG 11151080: TIME DELAYS AND MODELS (2007)
Paul L. Schechter, Charles D. Bailyn, Robert Barr, Richard Barvainis, Christopher M. Becker, Gary M. Bernstein, ...
12 TODD HURT,
Gary M. Bernstein, Puragra Guhathakurta, Somak Raychaudhury, Riccardo Giovanelli, Martha P. Haynes, Terry Herter, ...
We examine the precision of the Tully-Fisher relation (TFR) using a sample of galaxies in the Coma region of the sky, and find that it is good to 5 % or better in measuring relative distances. Total...
Tests of the Tully-Fisher Relation II: Scatter Using Optical Rotation Curves (2007)
Somak Raychaudhury, Kaspar Von Braun, Gary M. Bernstein, Puragra Guhathakurta
We investigate the amount of scatter in the Tully-Fisher relation (TFR) when using optical long-slit Hff rotation curves to determine the velocity widths of spiral galaxies. We study a sample of 25...
Detectability of CMB tensor B modes via delensing with weak lensing galaxy surveys (2007)
Marian, Laura, Bernstein, Gary M.
We analyze the possibility of delensing CMB polarization maps using foreground weak lensing (WL) information. We build an estimator of the CMB lensing potential out of optimally combined projected...
Dark energy constraints from lensing-detected galaxy clusters (2006)
Marian, Laura, Bernstein, Gary M.
We study the ability of weak lensing surveys to detect galaxy clusters and constrain cosmological parameters, in particular the equation of state of dark energy. There are two major sources of noise...
Lightcurves of 20--100 kilometer Kuiper Belt Objects using the Hubble Space Telescope (2005)
Trilling, David E., Bernstein, Gary M.
We report high precision photometry of three small and one larger Kuiper Belt Objects (KBOs) obtained with the Advanced Camera for Surveys onboard the Hubble Space Telescope (ACS/HST). The three...
Tests of the Tully-Fisher Relation II: Scatter Using Optical Rotation Curves (1997)
Raychaudhury, Somak, Von Braun, Kaspar, Bernstein, Gary M., Guhathakurta, Puragra
We investigate the amount of scatter in the Tully-Fisher relation (TFR) when using optical long-slit H-alpha rotation curves to determine the velocity widths of spiral galaxies. We study a sample of...
Detection of Lens Candidates for the Double QSO Q2345+007 (1994)
Fischer, Philippe, Tyson, J. Anthony, Bernstein, Gary M., Guhathakurta, Puragra
Luminous objects associated with the 7.06\arcsec\ separation double quasar Q2345+007 have, until now, escaped detection. In this letter we present the results of the deepest known imaging of the...
