On the normalized FRB luminosity function [PDF]

Monthly Notices of the Royal Astronomical Society, 2018
Thirty-three fast radio bursts (FRBs) had been detected by March 2018. Although the sample size is still limited, meaningful statistical studies can already be carried out. The normalised luminosity function places important constraints on the intrinsic power output, sheds light on the origin(s) of FRBs, and can guide future observations. In this paper,

The evolution of the galaxy UV luminosity function at redshifts z ≃ 8 – 15 from deep JWST and ground-based near-infrared imaging [PDF]

Monthly notices of the Royal Astronomical Society, 2022
We reduce and analyse the available JWST ERO and ERS NIRCam imaging (SMACS0723, GLASS, CEERS) in combination with the latest deep ground-based near-infrared imaging in the COSMOS field (provided by UltraVISTA DR5) to produce a new measurement of the ...

The Evolution of the IR Luminosity Function and Dust-obscured Star Formation over the Past 13 Billion Years [PDF]

Astrophysical Journal, 2021
We present the first results from the Mapping Obscuration to Reionization with ALMA (MORA) survey, the largest Atacama Large Millimeter/submillimeter Array (ALMA) blank-field contiguous survey to date (184 arcmin2) and the only at 2 mm to search for ...

The Evolution of the Lyman-alpha Luminosity Function during Reionization [PDF]

Astrophysical Journal, 2021
The time frame in which hydrogen reionization occurred is highly uncertain, but can be constrained by observations of Lyman-alpha (Lyα) emission from distant sources.

The bolometric quasar luminosity function at z = 0–7 [PDF]

Monthly notices of the Royal Astronomical Society, 2020
In this paper, we provide updated constraints on the bolometric quasar luminosity function (QLF) from z = 0 to z = 7. The constraints are based on an observational compilation that includes observations in the rest-frame IR, B band, UV, soft, and hard ...

On the FRB luminosity function – – II. Event rate density [PDF]

Monthly notices of the Royal Astronomical Society, 2020
The luminosity function of Fast Radio Bursts (FRBs), defined as the event rate per unit cosmic co-moving volume per unit luminosity, may help to reveal the possible origins of FRBs and design the optimal searching strategy. With the Bayesian modelling,

The Faint End of the Quasar Luminosity Function at z ∼ 5 from the Subaru Hyper Suprime-Cam Survey [PDF]

Astrophysical Journal, 2020
We present the quasar luminosity function at z ∼ 5 derived from the optical wide-field survey data obtained as a part of the Subaru strategic program (SSP) with the Hyper Suprime-Cam (HSC).

The extended Baryon Oscillation Spectroscopic Survey: Variability selection and quasar luminosity function [PDF]

, 2016
The SDSS-IV/eBOSS has an extensive quasar program that combines several selection methods. Among these, the photometric variability technique provides highly uniform samples, unaffected by the redshift bias of traditional optical-color selections, when ...

The subdwarf luminosity function [PDF]

Monthly Notices of the Royal Astronomical Society, 2003
Using data from the Sloan Digital Sky Survey Early Data Release and SuperCOSMOS Sky Survey scans of POSS-I plates we identify a sample of 2600 subdwarfs using reduced proper motion methods and strict selection criteria. This forms one of the largest and most reliable samples of candidate subdwarfs known, and enables us to determine accurate luminosity ...

Luminosity functions of cluster galaxies [PDF]

Astronomy & Astrophysics, 2018
We derive NUV luminosity functions for 6471 NUV detected galaxies in 28 0.02 < z < 0.08 clusters and consider their dependence on cluster properties. We consider optically red and blue galaxies and explore how their NUV LFs vary in several cluster subsamples, selected to best show the influence of environment.
