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…
EchoRec: Multi-Item Prediction-Empowered Generative Recommendation via Cycle-Consistent Preference Alignment
Haokai Ma, Aoqi Hu, Yueao Xing +5
Generative recommendation autoregressively generates the semantic IDs of the target item, unifying preference modeling and index retrieval within the shared token space. Recent att…
Radial velocity and atmospheric parameter calculations for the GaiaNIR spectrograph
Szabolcs Mészáros, David Hobbs, Anna Liptrott +8
Context. The upcoming GaiaNIR mission is currently planning to add a near-infrared spectrograph to its payload in order to enhance its scientific return, particularly for mapping t…
The MAGPI survey: Stellar population radial trends and mass assembly in star-forming galaxies at z~0.3
Federica Mauro, Bodo Ziegler, Iris Breda +20
The paper analyzes spatially resolved stellar populations in 34 star-forming galaxies at redshift ~0.3 using MUSE integral‑field spectroscopy, measuring radial gradients in age, me…
The MAGPI Survey: Evidence for Non-Universal Resolved Dust Attenuation Relations Beyond the Local Universe
A. Mailvaganam, T. Zafar, P. Corcho-Caballero +39
We study the spatially resolved relation between dust attenuation () and star formation rate surface density () in galaxies from the MAGPI survey ($0.25 < z…
Bar-driven secular evolution largely complete in a disk galaxy 7.6 billion years ago
Takafumi Tsukui, Zeyu Gao, Emily Wisnioski +4
Disk galaxies like the Milky Way are thought to evolve through internal dynamical processes: the stellar disk forms a bar, the bar drives gas inflow that builds a nuclear stellar d…
