Statistical evidence for massive black hole recoils in active galactic nuclei
Bence Bécsy, Peter Raffai, Zoltán Haiman +2
We search for a population-level signature of gravitational-wave recoiling supermassive black holes: a positive correlation between dust obscuration and the magnitude of the line-o…
LeMMINGs VII: 5 GHz, 50 mas e-MERLIN observations of a statistically complete sample of nearby AGN
D. R. A. Williams-Baldwin, R. D. Baldi, R. J. Beswick +36
We present 5 GHz e-MERLIN radio images at 50 mas resolution of the nuclear regions of the Legacy e-MERLIN Multi-band Imaging of Nearby Galaxies survey (LeMMINGs), the deepest stati…
Not all nitrogen-rich field stars originate from globular clusters
Ellen I. Leitinger, Andrea Miglio, Josefina Montalbán +7
Globular clusters (GCs) are important tracers of the early Galactic assembly process, with part of their stars showing distinct chemical abundance patterns. When such stars are fou…
Identifying and distinguishing quenching galaxies with spatially resolved star formation in TNG50
Cameron Lawlor-Forsyth, Michael L. Balogh, Elizaveta Sazonova +3
Using the TNG50 simulation, we determine observationally motivated metrics that can distinguish quenching galaxies from star forming galaxies for $M_{*} \geqslant 10^{9.5}~M_{\odot…
Mechanisms Affecting Galaxies Nearby and Environmental Trends (MAGNET)
Benedetta Vulcani, Gabriella De Lucia, Daria Zakharova +28
[ABRIDGED] Galaxy evolution is shaped by internal and external mechanisms that regulate the baryon cycle and star formation activity. We present a theoretical framework based on th…
Two faces of Gaia-Sausage-Enceladus: Mining the chemical abundance space with graph attention networks
Milan Quandt-Rodriguez, Sara Lucatello, Lorenzo Spina +2
Recent studies suggest that chemical abundances hold the key to disentangling halo substructure, providing a more reliable tracer than dynamics alone. We aim to probe the Milky Way…
