The Cetus-Palca stream: A disrupted small dwarf galaxy. A prequel to the science possible with WEAVE with precise spectro-photometric distances
Guillaume F. Thomas, Giuseppina Battaglia
We present a new fully data-driven approach to derive spectro-photometric distances based on artificial neural networks. The method was developed and tested on SEGUE data and will…
The phantom dark matter halos of the Local Volume in the context of modified Newtonian dynamics
P. -A. Oria, B. Famaey, G. F. Thomas +8
We explore the predictions of Milgromian gravity (MOND) in the Local Universe by considering the distribution of the `phantom' dark matter (PDM) that would source the MOND gravitat…
Uncovering fossils of the distant Milky Way with UNIONS: NGC 5466 and its stellar stream
Jaclyn Jensen, Guillaume Thomas, Alan W. McConnachie +9
We examine the spatial clustering of blue horizontal branch (BHB) stars from the -band of the Canada-France Imaging Survey (CFIS, a component of the Ultraviolet Near-In…
The Pristine Dwarf-Galaxy survey -- IV. Probing the outskirts of the dwarf galaxy Boötes I
Nicolas Longeard, Pascale Jablonka, Anke Arentsen +12
We present a new spectroscopic study of the dwarf galaxy Bootes I (Boo I) with data from the Anglo-Australian Telescope and its AAOmega spectrograph together with the Two Degree Fi…
Gaia early DR3 systemic motions of Local Group dwarf galaxies and orbital properties with a massive Large Magellanic Cloud
G. Battaglia, S. Taibi, G. F. Thomas +1
We perform a comprehensive determination of the systemic proper motions of 74 dwarf galaxies and dwarf galaxy candidates in the Local Group based on Gaia early data release 3. The…
The Pristine survey XIII: Uncovering the very metal-poor tail of the thin disc
Emma Fernández-Alvar, Georges Kordopatis, Vanessa Hill +9
We evaluate the rotational velocity of stars observed by the Pristine survey towards the Galactic anticentre, spanning a wide range of metallicities from the extremely metal-poor r…
