We have identified a complete, flux-limited (S 160>120 mJy) sample of 160 μm selected sources from Spitzer observations of the 1 deg2 Infrared Space Observatory (ISO) Deep Field region in the Lockman ...
We implement a new method by which to study the faint end of the field star luminosity function. The method relies on deep, multicolor photometry of fields projected against highly obscured, nearby mo...
Despite decades of study, it remains unclear whether there are distinct radio-loud and radio-quiet populations of quasi-stellar objects (QSOs). Early studies were limited by inhomogeneous QSO samples,...
SHELS (Smithsonian Hectospec Lensing Survey) is a dense redshift survey covering a 4 square degree region to a limiting R = 20.6. In the construction of the galaxy catalog and in the acquisition of sp...
We present new measurements of the H luminosity function (LF) and star-formation rate (SFR) volume density for galaxies at z ∼ 0.8. Our analysis is based on 1.18μm narrowband data from the NE...
We searched for quasars that are  3 mag fainter than the SDSS quasars in the redshift range 3.7 . z . 4.7 in the COSMOS field to constrain the faint end of the quasar luminosity function.
We report the first results from the Hubble Infrared Pure Parallel Imaging Extragalactic Survey, which utilizes the pure parallel orbits of the Hubble Space Telescope to do deep imaging along a large ...
The Planetary Nebulae Luminosity Function (PNLF) describes the collective luminosity evolution for a given population of Planetary Nebulae (PN). A major paradox in current PNLF studies is in the unive...
We constrain the evolution of the rest-frame far-infrared (FIR) luminosity function out to z~3.5 by combining several pieces of complementary information provided by the deep Balloon-borne Large-Apert...
Stellar populations in the calán-eso catalogue. The luminosity function and kinematics of dwarfs。
Chandra monitoring observation of the antennae Galaxies:the x-ray source populations and the shape of Their luminosity function

The Pulsar Luminosity Function
We propose a new analytic approximation for the luminosity function of galaxies. The suggested expression behaves like the Schechter function at the faint end (φ ∼ Lα) but departs considerably a...
