On estimating redshift and luminosity distributions in photometric redshift surveys
The luminosity functions of galaxies and quasars provide invaluable information about galaxy and quasar formation. Estimating the luminosity function from magnitude limited samples is relatively straightforward, provided that the distances to the objects in the sample are known accurately; techniques for doing this have been available for about thirty years. However, distances are usually known...
متن کاملCounts of Low-redshift SDSS Quasar Candidates
We analyze the counts of low-redshift quasar candidates selected using nine-epoch SDSS imaging data. The co-added catalogs are more than 1 mag deeper than single-epoch SDSS data, and allow the selection of low-redshift quasar candidates using UV-excess and also variability techniques. The counts of selected candidates are robustly determined down to g=21.5. This is about 2 magnitudes deeper tha...
متن کاملGalaxy evolution at low redshift? II. Number counts and optical identifications of faint IRAS sources
We analyse a Far InfraRed (FIR) catalogue of galaxies at 60 μm with a flux limit of ≈ 110 mJy, extracted from a deep subsample of the IRAS Faint Source Survey. MonteCarlo simulations and optical identification statistics are used to put constraints on the evolution of galaxies in the FIR. We find evidence for strong evolution of IRAS galaxies, in luminosity ∝ (1 + z)3.2±0.2±0.3 or density ∝ (1 ...
متن کاملThe Fluence and Distance Distributions of Fast Radio Bursts
Fast radio bursts (FRB) are millisecond-duration radio pulses with apparent extragalactic origins. All but two of the FRBs have been discovered using the Parkes dish, which employs multiple beams formed by an array of feed horns on its focal plane. In this paper, we show that (i) the preponderance of multiple-beam detections and (ii) the detection rates for varying dish diameters can be used to...
