Extreme (Rogue) Waves: From Theory to Experiments in Ultracold Gases and Beyond
A. Chabchoub, P. Engels, P. G. Kevrekidis +4
In this Chapter, we review key theoretical and experimental advances in the study of extreme nonlinear wave events, called rogue waves (RWs), in both single-component attractively…
The primordial nature of the C-19 stellar stream
Kim A. Venn, Zhen Yuan, Nicolas F. Martin +32
Stellar streams, remnants of compact star systems stretched out by the tidal forces of the Milky Way, offer a unique way to study stellar populations that formed billions of years…
GHOST commissioning science results -- IV: Chemodynamical analyses of Milky Way satellites Sagittarius II and Aquarius II
Daria Zaremba, Kim Venn, Christian R. Hayes +28
We present Gemini/GHOST high-resolution spectra of five stars observed in two low surface brightness Milky Way satellites, Sagittarius II (Sgr2) and Aquarius II (Aqu2). For Aqu2, t…
Deep in the Fields of the Andromeda Halo: Discovery of the Pegasus VII dwarf galaxy in UNIONS
Simon E. T. Smith, Alan W. McConnachie, Stephen Gwyn +8
We present the newly discovered dwarf galaxy Pegasus VII (Peg VII), a member of the M31 sub-group which has been uncovered in the photometric catalogs from the Ultraviolet Nea…
High-Resolution Dayside Spectroscopy of WASP-189b: Detection of Iron during the GHOST/Gemini South System Verification Run
Emily K. Deibert, Adam B. Langeveld, Mitchell E. Young +30
With high equilibrium temperatures and tidally locked rotation, ultra-hot Jupiters (UHJs) are unique laboratories within which to probe extreme atmospheric physics and chemistry. I…
GHOST Commissioning Science Results III: Characterizing an iron-poor damped Lyman system
Trystyn A. M. Berg, Christian R. Hayes, Stefano Cristiani +20
The Gemini High-resolution Optical SpecTrograph (GHOST) is a new echelle spectrograph available on the Gemini-South telescope as of Semester 2024A. We present the first high resolu…
The Science Performance of the Gemini High Resolution Optical Spectrograph
Alan W. McConnachie, Christian R. Hayes, J. Gordon Robertson +46
The Gemini High Resolution Optical Spectrograph (GHOST) is a fiber-fed spectrograph system on the Gemini South telescope that provides simultaneous wavelength coverage from 348 - 1…
The discovery of the faintest known Milky Way satellite using UNIONS
Simon E. T. Smith, William Cerny, Christian R. Hayes +14
We present the discovery of Ursa Major III/UNIONS 1, the least luminous known satellite of the Milky Way, which is estimated to have an absolute V-band magnitude of $+2.2^{+0.4}_{-…
SPLUS J142445.34-254247.1: An R-Process Enhanced, Actinide-Boost, Extremely Metal-Poor star observed with GHOST
Vinicius M. Placco, Felipe Almeida-Fernandes, Erika M. Holmbeck +33
We report on the chemo-dynamical analysis of SPLUS J142445.34-254247.1, an extremely metal-poor halo star enhanced in elements formed by the rapid neutron-capture process. This sta…
