Hector Galaxy Survey: Falling in Between - Infalling Galaxies in the Midst of the Abell 3667 Merger
Oğuzhan Çakır, Matt Owers, Gabriella Quattropani +38
Whether cluster mergers enhance ram pressure stripping (RPS) and accelerate member galaxy evolution remains an open question. Here, we investigate galaxy populations in the nearby…
The Wide-field Spectroscopic Telescope: optical designs for the low-resolution multi-object spectrographs
Will Saunders, Kjetil Dohlen, Dimitri Buffat +7
In MOS Low-Resolution mode, WST has a 'spectral etendue' per fiber (etendue x spectral resolution elements) twice as large as any existing MOS instrument, and a total spectral eten…
Hector Galaxy Survey: Linking the low- and high-mass ends of the initial mass function in star-forming galaxies
Diego Salvador, Andrew Hopkins, Matt Owers +30
The stellar initial mass function (IMF) is a fundamental ingredient in galaxy evolution, linking observed integrated light to galaxy properties. Constraining the full IMF shape bey…
Hector Galaxy Survey: Data Processing, Quality Control and Early Science
S. Oh, M. L. P. Gunawardhana, S. M. Croom +52
The Hector Galaxy Survey is a new optical integral field spectroscopy (IFS) survey currently using the AAT to observe up to 15,000 galaxies at low redshift (). The Hector…
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…
