Disc asymmetry characterisation in JWST-observed galaxies at 1 < z < 4
Ananya Ganapathy, Michael S. Petersen, Rashid Yaaqib +1
We present a novel technique using Fourier series and Laguerre polynomials to represent morphological features of disc galaxies. To demonstrate the utility of this technique, we st…
The Impact of Classical Bulges on Stellar Bars and Box-Peanut-X-Features in Disk Galaxies
Rachel Lee McClure, Angus Beane, Elena D'Onghia +2
Galactic bars and their associated resonances play a significant role in shaping galaxy evolution. Resulting resonance-driven structures, like the vertically extended Boxy/Peanut X…
Triangulum IV: A Possible Ultra-Diffuse Satellite of M33
Itsuki Ogami, Yutaka Komiyama, Masashi Chiba +8
We report the detection of a dwarf satellite candidate (Triangulum IV: Tri IV) of the Triangulum galaxy (M33) using the deep imaging of Subaru/Hyper Suprime-Cam (HSC). From the app…
[X/Fe] Marks the Spot: Mapping Chemical Azimuthal Variations in the Galactic Disk with APOGEE
Zoe Hackshaw, Keith Hawkins, Carrie Filion +4
Chemical cartography of the Galactic disk provides insights to its structure and assembly history over cosmic time. In this work, we use chemical cartography to explore chemical gr…
The Low-Mass Stellar Initial Mass Function in Nearby Ultrafaint Dwarf Galaxies
Carrie Filion, Rosemary F. G. Wyse, Hannah Richstein +3
The stellar initial mass function (IMF) describes the distribution of stellar masses that form in a given star formation event. The long main-sequence lifetimes of low-mass stars m…
Detection of a Spatially Extended Stellar Population in M33: A Shallow Stellar Halo?
Itsuki Ogami, Yutaka Komiyama, Masashi Chiba +8
We analyze the outer regions of M33, beyond 15 kpc in projected distance from its center using Subaru/HSC multi-color imaging. We identify Red Giant Branch (RGB) stars and Red Clum…
Radial phase spirals in the Solar neighbourhood
Jason A. S. Hunt, Adrian M. Price-Whelan, Kathryn V. Johnston +4
The second data release of ESA's mission revealed numerous signatures of disequilibrium in the Milky Way's disc. These signatures are seen in the planar kinematics of stars,…
The structure of the stellar halo of the Andromeda galaxy explored with the NB515 for Subaru/HSC. I.: New Insights on the stellar halo up to 120 kpc
Itsuki Ogami, Mikito Tanaka, Yutaka Komiyama +16
We analyse the M31 halo and its substructure within a projected radius of 120 kpc using a combination of Subaru/HSC and CFHT/MegaCam - \& -…
