Kinetic Monte Carlo simulations of ice processing: from the lab to interstellar environments Open

Aspen R. Clements, R. T. Garrod, Ilsa R. Cooke, Brandon Berk · 2020

Dust grains in cold, dense interstellar clouds build up ice mantles through the accretion and subsequent surface chemistry of atoms and molecules from the gas. These mantles, of thicknesses on the order of 100 monolayers, are primarily com…

The Effective Surface Area of Amorphous Solid Water Measured by the Infrared Absorption of Carbon Monoxide Open

Jiao He, Aspen R. Clements, SM Emtiaz, Francis Toriello, Robin T Garrod , et al. · 2019

The need to characterize ices coating dust grains in dense interstellar clouds arises from the importance of ice morphology in facilitating the diffusion and storage of radicals and reaction products in ices, a well-known place for the for…

A Centimeter-wave Study of Methanol and Ammonia Isotopologues in Sgr B2(N): Physical and Chemical Differentiation between Two Hot Cores Open

Elisabeth A. C. Mills, Joanna Corby, Aspen R. Clements, Natalie Butterfield, P. A. Jones , et al. · 2018

We present new radio-frequency interferometric maps of emission from the 14 NH 3 , 15 NH 3 , and NH 2 D isotopologues of ammonia and the 12 CH 3 OH and 13 CH 3 OH isotopologues of methanol toward Sgr B2(N). With a resolution of ∼3″ (0.1 pc…

Discovery of <sup>14</sup>NH<sub>3</sub> (2,2) Maser Emission in Sgr B2 Main Open

Elisabeth A. C. Mills, Adam Ginsburg, Aspen R. Clements, P. Schilke, Á. Sánchez-Monge , et al. · 2018

We report the discovery of the first 14 NH 3 (2,2) maser, seen in the Sgr B2 Main star-forming region near the center of the Milky Way, using data from the Very Large Array radio telescope. The maser is seen in both lower-resolution (3″ or…
