The Forward Physics Facility at the High-Luminosity LHC [PDF]

open access: yesJournal of Physics G: Nuclear and Particle Physics, 2022
High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large number of particles along the beam collision axis, outside of the acceptance of existing LHC experiments.

GOLDRUSH. IV. Luminosity Functions and Clustering Revealed with ∼4,000,000 Galaxies at z ∼ 2–7: Galaxy–AGN Transition, Star Formation Efficiency, and Implication for Evolution at z > 10 [PDF]

open access: yesAstrophysical Journal Supplement Series, 2021
We present new measurements of rest-UV luminosity functions and angular correlation functions from 4,100,221 galaxies at z ∼ 2–7 identified in the Subaru/Hyper Suprime-Cam survey and CFHT Large Area U-band Survey. The obtained luminosity functions at z ∼

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

open access: yesMonthly 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 ...

Reverberation Measurements for 17 Quasars and the Size-Mass-Luminosity Relations in Active Galactic Nuclei [PDF]

open access: yes, 1999
Correlated variations in the line and continuum emission from active galactic nuclei (AGNs) can be used to determine the size and geometry of the broad emission-line regions (BLRs).

Subaru High-z Exploration of Low-luminosity Quasars (SHELLQs). V. Quasar Luminosity Function and Contribution to Cosmic Reionization at z = 6 [PDF]

open access: yesAstrophysical Journal, 2018
We present new measurements of the quasar luminosity function (LF) at z ∼ 6 over an unprecedentedly wide range of the rest-frame ultraviolet luminosity M1450 from −30 to −22 mag.

Discovery of the First Low-luminosity Quasar at z > 7 [PDF]

open access: yesAstrophysical Journal, 2019
We report the discovery of a quasar at z = 7.07, which was selected from the deep multi-band imaging data collected by the Hyper Suprime-Cam (HSC) Subaru Strategic Program survey.

Evolution of the AGN UV luminosity function from redshift 7.5 [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2018
Determinations of the ultraviolet (UV) luminosity function of active galactic nuclei (AGN) at high redshifts are important for constraining the AGN contribution to reionization and understanding the growth of supermassive black holes.

Leaf anatomy and morpho-physiological mechanisms of acclimation to high irradiance in heliconia genotypes

open access: yesCiência e Agrotecnologia, 2023
The amount of solar irradiation available in the growing environment can cause significant changes in physiology and leaf anatomy that enable crops to acclimate to different light conditions.
