I., Rigamonti, F., Yang, M., Fahrion, K., & van de Ven, G. (2022). Testing the robustness of DYNAMITE triaxial Schwarzschild modelling: The effects of correcting the orbit mirroring. Astronomy & Astrophysics, 667, Article A51. https://doi.org/10.1051/0004-6361/202243926

In the past 15 yr, the triaxial Schwarzschild orbit-superposition code developed by van den Bosch and van de Ven in Leiden has been widely applied to study the dynamics of galaxies. Recently, a bug was reported in the orbit calculation of this code,...

This work is based on high-quality integral-field spectroscopic data obtained with the Multi Unit Spectroscopic Explorer (MUSE) on the Very Large Telescope (VLT). The 21 brightest (mB ≤ 15 mag) early-type galaxies (ETGs) inside the virial radius of t...

Monthly Notices of the Royal Astronomical Society, 514(3), 3660-3669. https://doi.org/10.1093/mnras/stac1514

Variations of the stellar initial mass function (IMF) in external galaxies have been inferred from a variety of independent probes. Yet the physical conditions causing these variations remain largely unknown. In this work, we explore new spatially re...

The SAMI Galaxy Survey: The Internal Orbital Structure and Mass Distribution of Passive Galaxies from Triaxial Orbit-superposition Schwarzschild Models (2022)
Journal Article
Santucci, G., Brough, S., van de Sande, J., McDermid, R. M., van de Ven, G., Zhu, L., D’Eugenio, F., Bland-Hawthorn, J., Barsanti, S., Bryant, J. J., M. Croom, S., Davies, R. L., Green, A.

Astrophysical Journal, 930(2), Article 153. https://doi.org/10.3847/1538-4357/ac5bd5

Dynamical models are crucial for uncovering the internal dynamics of galaxies; however, most of the results to date assume axisymmetry, which is not representative of a significant fraction of massive galaxies. Here, we build triaxial Schwarzschild o...

Comparing lensing and stellar orbital models of a nearby massive strong-lens galaxy (2022)
Journal Article
Poci, A., & Smith, R. J. (2022). Comparing lensing and stellar orbital models of a nearby massive strong-lens galaxy. Monthly Notices of the Royal Astronomical Society, 512(4), 5298-5310. https://doi.org/10.1093/mnras/stac776

Exploiting the relative proximity of the nearby strong-lens galaxy SNL-1, we present a critical comparison of the mass estimates derived from independent modelling techniques. We fit triaxial orbit-superposition dynamical models to spatially resolved... Read More about Comparing lensing and stellar orbital models of a nearby massive strong-lens galaxy.
