Properties of Spectroscopically-Confirmed Galaxies at z >= 6

Title: Properties of Spectroscopically-Confirmed Galaxies at z >= 6

Speaker: Linhua Jiang (KIAA/PKU)

Time: 3 PM, June 8 (Thursday)

Location: Lecture Hall, 3rd floor

Abstract:

Star-forming galaxies at redshift z >= 6 are natural tools to study the early galaxy formation and explore the history of cosmic reionization. In this talk, I will present our recent work on our understanding of these high-redshift galaxies. The talk will consist of two parts.In the first part, I will present the physical properties of a sample of spectroscopically confirmed galaxies at z>=6, including nearly 70 Lyman-alpha emitters (LAEs) and Lyman-break galaxies (LBGs). They have deep multi-band data and secure redshifts that allow us to reliably measure their physical properties.In the second part of the talk, I will introduce our on-going program that uses Magellan M2FS to spectroscopically identify a large number galaxy candidates at 5.6 < z < 7. M2FS is one of the most efficient instruments to identify relatively bright high-redshift galaxies. When the program completes, we will build the largest (in terms of areal coverage) sample of luminous,

spectroscopically-confirmed galaxies in this redshift range.This galaxy sample will be used to study physical properties of high-redshift galaxies and their implications to cosmic reionization.
