Astropy: A Community Python Package for Astronomy
The Astropy Collaboration, Thomas P. Robitaille, Erik J. Tollerud +42
We present the first public version (v0.2) of the open-source and community-developed Python package, Astropy. This package provides core astronomy-related functionality to the com…
Line Transfer through Clumpy, Large-Scale Outflows: Lyman Alpha Absorption and Halos around Starforming Galaxies
Mark Dijkstra, Roban Hultman Kramer
We present constrained radiative transfer calculations of Lyman Alpha (Lya) photons propagating through clumpy, dusty, large scale outflows, and explore whether we can quantitative…
Delayed Enrichment by Unseen Galaxies: Explaining the Rapid Rise in IGM CIV Absorption from z = 6-5
Roban Hultman Kramer, Zoltán Haiman, Piero Madau
In the near future, measurements of metal absorption features in the intergalactic medium (IGM) will become an important constraint on models of the formation and evolution of the…
Probing Reionization with Quasar Spectra: the Impact of the Intrinsic Lyman-alpha Emission Line Shape Uncertainty
Roban Hultman Kramer, Zoltan Haiman
Arguably the best hope of understanding the tail end of the reionization of the intergalactic medium (IGM) at redshift z > 6 is through the detection and characterization of the Gu…
The Thickness of High-Redshift Quasar Ionization Fronts as a Constraint on the Ionizing Spectral Energy Distribution
Roban Hultman Kramer, Zoltán Haiman
High-redshift quasars (z >~ 6) drive ionization fronts into the intergalactic medium (IGM). If the thickness of the front can be measured, it can provide a novel constraint on the…
Wind signatures in the X-ray emission line profiles of the late O supergiant Orionis
David H. Cohen, Maurice A. Leutenegger, Kevin T. Grizzard +3
X-ray line profile analysis has proved to be the most direct diagnostic of the kinematics and spatial distribution of the very hot plasma around O stars. In this paper we apply sev…
