Dust-to-Gas Ratio in the Extremely Metal Poor Galaxy I ZW 18
Rodrigo Herrera-Camus, David B. Fisher, Alberto D. Bolatto +7
The blue compact dwarf galaxy I Zw 18 is one of the most metal poor systems known in the local Universe (12 + log(O/H) 7.17). In this work we study I Zw 18 using data from {\it…
Dust May Be More Rare Than Expected in Metal Poor Galaxies
David B. Fisher, Alberto D. Bolatto, Rodrigo Herrera-Camus +7
'Normal' galaxies observed at z>6, when the Universe was <1 billion years old, thus far show no evidence of the cold dust that accompanies star formation in the local Universe, whe…
New Parallaxes for the Upper Scorpius OB Association
Jessica Donaldson, Alycia Weinberger, Jonathan Gagné +2
Upper Scorpius is a subgroup of the nearest OB association, Scorpius--Centaurus. Its young age makes it an important association to study star and planet formation. We present para…
A Uniform Analysis of Debris Disks with the Gemini Planet Imager II: Constraints on Dust Density Distribution Using Empirically-Informed Scattering Phase Functions
Justin Hom, Jennifer Patience, Christine H. Chen +40
Spatially-resolved images of debris disks are necessary to determine disk morphological properties and the scattering phase function (SPF) which quantifies the brightness of scatte…
