Observations of Cosmic Dust Evolution using GRBsDaniel Perley2009 年 04 月 22 日

Introduction

● How does high-z dust differ from local dust?– How much dust at z>3,4,5? (When did most of it form?)– Does it have the same composition, size distribution, and

observational signatures as dust today?– What can it tell us about conditions in early galaxies?

● GRBs: excellent tools for probing high-z dust– Extremely luminous: visible to extreme redshifts– Occur in “typical” star-forming galaxies– Intrinsically simple spectrum (F = λβ)

Summary

GRB 080607:● Large dust column in star-forming galaxy at z>3● Probing sightline through molecular cloud● Solar metallicity, dust resembles MW, LMC but

not SMC, suggesting similar conditions to now: mature, dusty star-forming galaxy?

● Highest-redshift detection of 2175Å feature: carrier was formed (in part) by t = 2 Gyr.

Conclusions

● Diffuse MW / LMC / SMC is not the whole story

● 080607: Galactic-like molecular cloud at z=3 with weaker 2175 Å carrier

● 071025: Plenty of dust at z=5, extinction law resembles z>5 quasars and modeled dust from Type II Sne

● SN → AGB production transition at z~5?
