Lyman Break Galaxies at $z\sim5$: Rest-Frame UV Spectra

, 2004
We report initial results for spectroscopic observations of candidates of Lyman Break Galaxies (LBGs) at $z\sim5$ in a region centered on the Hubble Deep Field-North by using the Faint Object Camera and Spectrograph attached to the Subaru Telescope ...

Spectroscopic Studies of z~5.7 and z~6.5 Galaxies: Implications for Reionization [PDF]

, 2005
The recent development of large, complete samples which identify high-redshift galaxies at z~5.7 and z~6.5 from deep, wide-field surveys provides detailed information on the earliest galaxies, their numbers, spatial and kinematic distributions, and ...

Spectroscopic Ultraluminous Lyα Luminosity Functions at z = 5.7 and z = 6.6 from HEROES: Evidence for Ionized Bubbles

The Astrophysical Journal
We present spectroscopic Ly α luminosity functions (LFs) at z = 5.7 and z = 6.6 based on a large 209 source sample of Ly α emitter (LAE) candidates identified in Subaru/Hyper Suprime-Cam narrowband imaging and confirmed with Keck II/DEIMOS spectroscopy ...

Models for Dusty Lyman alpha Emitters at High Redshift

, 1998
Models are presented for the Lyman alpha emission of dusty high-redshift galaxies by combining the Press-Schechter formalism with a treatment of the inhomogeneous dust distribution inside galaxies.

Impact of Cosmic Ray-driven Outflows on Lyα Emission in Cosmological Simulations

The Astrophysical Journal
Cosmic ray (CR) feedback has been proposed as a powerful mechanism for driving warm gas outflows in galaxies. We use cosmological magnetohydrodynamic simulations to investigate the impact of CR feedback on neutral hydrogen (H i ) in a 10 ^11 M _⊙ dark ...

Quasar Negative Feedback to Surrounding Galaxies Probed with Lyα Emitters and Continuum-selected Galaxies

The Astrophysical Journal Letters
We report on the statistical analysis of quasar photoevaporation at z  ∼ 2.2 by comparing the density of surrounding Ly α emitters (LAEs) and continuum-selected galaxies, based on the imaging data of the Hyper Suprime-Cam (HSC) Subaru Strategic Program ...

The nature of z ~ 2.3 Lyman-alpha emitters

, 2011
We study the multi-wavelength properties of a set of 171 Ly-alpha emitting candidates at redshift z = 2.25 found in the COSMOS field, with the aim of understanding the underlying stellar populations in the galaxies.

Testing Lyα Emitters and Lyman-break Galaxies as Tracers of Large-scale Structures at High Redshifts

The Astrophysical Journal
We test whether Lyα emitters (LAEs) and Lyman-break galaxies (LBGs) can be good tracers of high- z large-scale structures, using the Horizon Run 5 cosmological hydrodynamical simulation.

Constraints on the z  ∼  6−13 intergalactic medium from JWST spectroscopy of Lyman-alpha damping wings in galaxies

Astronomy & Astrophysics
Context. JWST provides a unique dataset for studying the earliest stages of reionisation at z > 9, promising insights into the first galaxies. Many JWST/NIRSpec prism spectra of z > 5 galaxies have revealed smooth Lyman-alpha breaks, implying damping ...
