The MUSE eXtremely Deep Field: Detections of circumgalactic SiII* emission at z>~2
Haruka Kusakabe, Valentin Mauerhofer, Anne Verhamme +17
The circumgalactic medium (CGM) serves as a baryon reservoir that connects galaxies to the intergalactic medium and fuels star formation. The spatial distribution of the metal-enri…
The Wide-field Spectroscopic Telescope (WST) Science White Paper
Vincenzo Mainieri, Richard I. Anderson, Jarle Brinchmann +214
The Wide-field Spectroscopic Telescope (WST) is proposed as a new facility dedicated to the efficient delivery of spectroscopic surveys. This white paper summarises the initial con…
Bipolar Outflows out to 10~kpc for Massive Galaxies at Redshift
Yucheng Guo, Roland Bacon, Nicolas F. Bouché +15
Galactic outflows are believed to play a critical role in the evolution of galaxies by regulating their mass build-up and star formation. Theoretical models assumes bipolar shapes…
Spatially-resolved Spectroscopic Analysis of Ly Haloes: Radial Evolution of the Ly Line Profile out to 60 kpc
Yucheng Guo, Roland Bacon, Lutz Wisotzki +11
The extended Ly haloes (LAHs) have been found to be prevalent around high-redshift star-forming galaxies. However, the origin of the LAHs is still a subject of debate. Spatially…
Median Surface Brightness Profiles of Lyman- Haloes in the MUSE Extremely Deep Field
