Decoupling the rotation of stars and gas -- II: the link between black hole activity and MaNGA kinematics in TNG
Christopher Duckworth, Tjitske K. Starkenburg, Shy Genel +4
We study the relationship between supermassive black hole (BH) feedback, BH luminosity and the kinematics of stars and gas for galaxies in IllustrisTNG. We use a sample of galaxies…
SPECULATOR: Emulating stellar population synthesis for fast and accurate galaxy spectra and photometry
Justin Alsing, Hiranya Peiris, Joel Leja +6
We present SPECULATOR - a fast, accurate, and flexible framework for emulating stellar population synthesis (SPS) models for predicting galaxy spectra and photometry. For emulating…
Decoupling the rotation of stars and gas -- I: the relationship with morphology and halo spin
Christopher Duckworth, Rita Tojeiro, Katarina Kraljic
We use a combination of data from the MaNGA survey and MaNGA-like observations in IllustrisTNG100 to determine the prevalence of misalignment between the rotational axes of stars a…
The VIMOS Public Extragalactic Redshift Survey (VIPERS) -- Environment-size relation of massive passive galaxies at 0.5 < z < 0.8
A. Gargiulo, O. Cucciati, B. Garilli +36
We use the statistics of the VIPERS survey to investigate the relation between the surface mean stellar mass density Sigma=Mstar/(2*pi*Re^2) of massive passive galaxies (MPGs, Msta…
