Inferring redshift and galaxy properties via a multi-task neural net with probabilistic outputs: An application to simulated MOONS spectra
Michele Ginolfi, Filippo Mannucci, Francesco Belfiore +11
The era of large-scale astronomical surveys demands innovative approaches for rapid and accurate analysis of extensive spectral data, and a promising direction in which to address…
SDSS-IV MaNGA: Stellar rotational support in disk galaxies vs. central surface density and stellar population age
Xiaohan Wang, Yifei Luo, S. M. Faber +10
We investigate how the stellar rotational support changes as a function of spatially resolved stellar population age () and relative central stellar surface density ($…
A tight N/O-potential relation in star-forming galaxies
Nicholas Fraser Boardman, Vivienne Wild, Natalia Vale Asari
We report a significantly tighter trend between gaseous N/O and (a proxy for gravitational potential) than has previously been reported between gaseous metallicity and $M…
Chemical evolution of local post-starburst galaxies: Implications for the mass-metallicity relation
Ho-Hin Leung, Vivienne Wild, Michail Papathomas +5
We use the stellar fossil record to constrain the stellar metallicity evolution and star-formation histories of the post-starburst (PSB) regions within 45 local post-starburst gala…
Dark matter measurements combining stellar and HI kinematics: 30% outliers with low dark matter content at
Meng Yang, Ling Zhu, Yu Lei +5
We construct the Schwarzschild dynamical models for 11 early-type galaxies with the SAURON and Mitchell stellar IFUs out to , and construct dynamical models with…
