The change of the total mass density slope, , of early-type galaxies through cosmic time is a probe of evolutionary pathways. Hydrodynamical cosmological simulations show that…
The SLUGGS survey: a new mask design to reconstruct the stellar populations and kinematics of both inner and outer galaxy regions
Nicola Pastorello, Duncan A. Forbes, Adriano Poci +7
Integral field unit spectrographs allow the 2D exploration of the kinematics and stellar populations of galaxies, although they are generally restricted to small fields-of-view. Us…
The SAMI Galaxy Survey: a statistical approach to an optimal classification of stellar kinematics in galaxy surveys
Jesse van de Sande, Sam P. Vaughan, Luca Cortese +22
Large galaxy samples from multi-object IFS surveys now allow for a statistical analysis of the z~0 galaxy population using resolved kinematics. However, the improvement in number s…
The SAMI Galaxy Survey: The internal orbital structure and mass distribution of passive galaxies from triaxial orbit-superposition Schwarzschild models
Giulia Santucci, Sarah Brough, Jesse van de Sande +17
Dynamical models are crucial for uncovering the internal dynamics of galaxies, however, most of the results to date assume axisymmetry, which is not representative for a significan…

Adriano Poci, Russell J. Smith
We present a dynamical and chemical study of the centre of a massive early-type strong-lens galaxy ESO286-G022 (SNL-1). Analysing new data obtained through the adaptive-optics-assi…
Evolution in the orbital structure of quiescent galaxies from MAGPI, LEGA-C and SAMI surveys: direct evidence for merger-driven growth over the last 7 Gy
Francesco D'Eugenio, Arjen van der Wel, Joanna M. Piotrowska +37
We present the first study of spatially integrated higher-order stellar kinematics over cosmic time. We use deep rest-frame optical spectroscopy of quiescent galaxies at redshifts…
Lopsidedness in Early-Type Galaxies: the role of the multipole in Isophote Fitting and Strong Lens Modelling
Aristeidis Amvrosiadis, James W. Nightingale, Qiuhan He +6
The surface brightness distribution of massive early-type galaxies (ETGs) often deviates from a perfectly elliptical shape. To capture these deviations in their isophotes during an…
The MAGPI Survey: Impact of environment on the total internal mass distribution of galaxies in the last 5 Gyr
Caro Derkenne, Richard M. McDermid, Adriano Poci +20
We investigate the impact of environment on the internal mass distribution of galaxies using the Middle Ages Galaxy Properties with Integral field spectroscopy (MAGPI) survey. We u…
The Fornax3D project: discovery of ancient massive merger events in the Fornax cluster galaxies NGC 1380 and NGC 1427
Ling Zhu, Glenn van de Ven, Ryan Leaman +16
We report the discovery of ancient massive merger events in the early-type galaxies NGC 1380 and NGC 1427, members of the Fornax galaxy cluster. Both galaxies have been observed by…
The distribution of stellar orbits in Eagle galaxies -- the effect of mergers, gas accretion, and secular evolution
Giulia Santucci, Claudia Del P. Lagos, Katherine E. Harborne +9
The merger history of a galaxy is thought to be one of the major factors determining its internal dynamics, with galaxies having undergone different types or mergers (e.g. dry, min…
On the robustness of triaxial Schwarzschild modelling: The effects of correcting the orbit mirroring
Sabine Thater, Prashin Jethwa, Behzad Tahmasebzadeh +13
In the past 15 years, the triaxial Schwarzschild orbit-superposition code by van den Bosch et al. (2008) has been widely applied to study the dynamics of galaxies. Recently, Quenne…
