Autor: Dawn K. Erb, Zhihui Li, Charles C. Steidel, Yuguang Chen, Max Gronke, Allison L. Strom, Ryan F. Trainor, Gwen C. Rudie

Publikováno v: The Astrophysical Journal, Vol 953, Iss 1, p 118 (2023)

The resonantly scattered Ly α line illuminates the extended halos of neutral hydrogen in the circumgalactic medium of galaxies. We present integral field Keck Cosmic Web Imager observations of double-peaked, spatially extended Ly α emission in 12 r

Lyα Scattering Models Trace Accretion and Outflow Kinematics in T Tauri Systems

Publikováno v: The Astrophysical Journal, Vol 944, Iss 2, p 185 (2023)

T Tauri stars produce broad Ly α emission lines that contribute ∼88% of the total UV flux incident on the inner circumstellar disks. Ly α photons are generated at the accretion shocks and in the protostellar chromospheres and must travel through

Spectral shapes of the Ly α emission from galaxies – II. The influence of stellar properties and nebular conditions on the emergent Ly α profiles

Autor: Matthew J Hayes, Axel Runnholm, Claudia Scarlata, Max Gronke, T Emil Rivera-Thorsen

Publikováno v: Monthly Notices of the Royal Astronomical Society. 520:5903-5927

We demonstrate how the stellar and nebular conditions in star-forming galaxies modulate the emission and spectral profile of HI Lya emission line. We examine the net Lya output, kinematics, and in particular emission of blue-shifted Lya radiation, us

Cloudy with a chance of rain: accretion braking of cold clouds

Autor: Brent Tan, S Peng Oh, Max Gronke

Publikováno v: Monthly Notices of the Royal Astronomical Society. 520:2571-2592

Understanding the survival, growth and dynamics of cold gas is fundamental to galaxy formation. While there has been a plethora of work on `wind tunnel' simulations that study such cold gas in winds, the infall of this gas under gravity is at least e

On the evolution of the size of Lyman alpha haloes across cosmic time: no change in the circumgalactic gas distribution when probed by line emission

Publikováno v: Monthly Notices of the Royal Astronomical Society, 522 (3)

Lyman α (Lyα) is now routinely used as a tool for studying high-redshift galaxies, and its resonant nature means it can trace neutral hydrogen around star-forming galaxies. Integral field spectrograph measurements of high-redshift Lyα emitters ind

Lyman-alpha Scattering Models Trace Accretion and Outflow Kinematics in T Tauri Systems

T Tauri stars produce broad Lyman-alpha emission lines that contribute $\sim$88% of the total UV flux incident on the inner circumstellar disks. Lyman-alpha photons are generated at the accretion shocks and in the protostellar chromospheres and must

Tracing the kinematics of the whole ram pressure stripped tails in ESO 137-001

Autor: Rongxin Luo, Ming Sun, Pavel Jáchym, Will Waldron, Matteo Fossati, Michele Fumagalli, Alessandro Boselli, Francoise Combes, Jeffrey D P Kenney, Yuan Li, Max Gronke

Ram pressure stripping (RPS) is an important process to affect the evolution of cluster galaxies and their surrounding environment. We present a large MUSE mosaic for ESO 137-001 and its stripped tails, and study the detailed distributions and kinema

We present the first results from the X-SHOOTER Lyman-$\alpha$ survey at $z=2$ (XLS-$z2$). XLS-$z2$ is a deep spectroscopic survey of 35 Lyman-$\alpha$ emitters (LAEs) utilising $\approx90$ hours of exposure time with VLT/X-SHOOTER and covers rest-fr
