Unlocking the Capabilities of Future High-Resolution X-ray Spectroscopy Missions Through Laboratory Astrophysics

Gabriele Betancourt-Martinez, Hiroki Akamatsu, Didier Barret +46

Thanks to high-resolution and non-dispersive spectrometers onboard future X-ray missions such as XRISM and Athena, we are finally poised to answer important questions about the for…

H, He-like recombination spectra I: -changing collisions for hydrogen

F. Guzmán, N. R. Badnell, R. J. R. Williams +3

Hydrogen and helium emission lines in nebulae form by radiative recombination. This is a simple process which, in principle, can be described to very high precision. Ratios of He I…

The Lexington Benchmarks for Numerical Simulations of Nebulae

G. Ferland, L. Binette, M. Contini +9

We present the results of a meeting on numerical simulations of ionized nebulae held at the University of Kentucky in conjunction with the celebration of the 70th birthdays of Prof…

Stout: Cloudy's Atomic and Molecular Database

M. L. Lykins, G. J. Ferland, R. Kisielius +6

We describe a new atomic and molecular database we developed for use in the spectral synthesis code Cloudy. The design of Stout is driven by the data needs of Cloudy, which simulat…

Corrigendum: Improved He~I Emissivities in the Case B Approximation

R. L. Porter, G. J. Ferland, P. J. Storey +1

Errors were discovered in our recent calculations of HeI emissivities (Porter et al. 2012; arXiv:1206.4115). This corrigendum discusses the errors and reports corrected emissivitie…

Quasar Metal Abundances and Host Galaxy Evolution

Fred Hamann, Craig Warner, Matthias Dietrich +1

Quasars signal a unique phase of galaxy evolution -- when massive spheroids are rapidly being assembled, forming stars and growing their central super-massive black holes. Measurem…
