An analytic expression for the luminosity function for galaxies
- P. Schechter
- Physics
- 15 January 1976
A new analytic approximation for the luminosity function for galaxies is proposed, which shows good agreement with both a luminosity distribution for bright nearby galaxies and a composite luminosity…

The Luminosity Function of Galaxies in the Las Campanas Redshift Survey
- Huan Lin, R. Kirshner, P. Schechter
- Physics
- 13 February 1996
We present the $R$-band luminosity function for a sample of 18678 galaxies, with average redshift $z = 0.1$, from the Las Campanas Redshift Survey. The luminosity function may be fit by a Schechter…
The Las Campanas Redshift Survey
- S. Shectman, S. Landy, P. Schechter
- Physics
- 28 April 1996
The Las Campanas Redshift Survey (LCRS) consists of 26418 redshifts of galaxies selected from a CCD-based catalog obtained in the $R$ band. The survey covers over 700 square degrees in 6 strips, each…
DOPHOT, A CCD PHOTOMETRY PROGRAM: DESCRIPTION AND TESTS
- P. Schechter, M. Mateo, A. Saha
- Physics
- 1 November 1993
The design considerations and operation features of DoPHOT, a point spread function fitting (PSF) photometry program, are described. Some relevant details of the PSF fitting are discussed. The…

The Velocity Dispersion Function of Early-Type Galaxies
- R. Sheth, M. Bernardi, Ž. Ivezić
- Physics
- 4 March 2003
The distribution of early-type galaxy velocity dispersions, ϕ(σ), is measured using a sample drawn from the Sloan Digital Sky Survey database. Its shape differs significantly from that obtained by…
FIRE: A Facility Class Near-Infrared Echelle Spectrometer for the Magellan Telescopes
- R. Simcoe, A. Burgasser, J. Bochanski
- Physics
- 21 March 2013
We describe the design, construction, and commissioning of FIRE, a 0.82–2.51 μ m echelle spectrograph for the 6.5 m Magellan Baade telescope. FIRE may be operated in two modes. Its primary mode is a…
SIZES AND TEMPERATURE PROFILES OF QUASAR ACCRETION DISKS FROM CHROMATIC MICROLENSING
- J. Blackburne, D. Pooley, S. Rappaport, P. Schechter
- Physics, Geology
- 9 July 2010
Microlensing perturbations to the flux ratios of gravitationally lensed quasar images can vary with wavelength because of the chromatic dependence of the accretion disk's apparent size.…
Quasar Microlensing at High Magnification and the Role of Dark Matter: Enhanced Fluctuations and Suppressed Saddle Points
- P. Schechter, J. Wambsganss
- Physics
- 25 April 2002
Contrary to naive expectation, diluting the stellar component of the lensing galaxy in a highly magnified system with smoothly distributed "dark" matter increases rather than decreases the…
