Globular Cluster Systems of Relic Galaxies

Karla A. Alamo-Martínez, Ana L. Chies-Santos, Michael A. Beasley +6

We analyse the globular cluster (GC) systems of a sample of 15 massive, compact early-type galaxies (ETGs), 13 of which have already been identified as good relic galaxy candidates…

The inside-out formation of nuclear discs and the absence of old central spheroids in barred galaxies of the TIMER survey

Adrian Bittner, Patricia Sánchez-Blázquez, Dimitri A. Gadotti +13

The centres of disc galaxies host a variety of structures built via both internal and external processes. In this study, we constrain the formation and evolution of these central s…

Kinematic signatures of nuclear discs and bar-driven secular evolution in nearby galaxies of the MUSE TIMER project

Dimitri A. Gadotti, Adrian Bittner, Jesus Falcon-Barroso +13

The central regions of disc galaxies hold clues to the processes that dominate their formation and evolution. The TIMER project has obtained high signal-to-noise and spatial resolu…

Reconstructing the mass accretion histories of nearby Red Nuggets with their globular cluster systems

Michael A. Beasley, Ryan Leaman, Ignacio Trujillo +6

It is generally recognized that massive galaxies form through a combination of in-situ collapse and ex-situ accretion. The in-situ component forms early, where gas collapse and com…

Recovering age-metallicity distributions from integrated spectra: validation with MUSE data of a nearby nuclear star cluster

A. Boecker, M. Alfaro-Cuello, N. Neumayer +2

Current instruments and spectral analysis programs are now able to decompose the integrated spectrum of a stellar system into distributions of ages and metallicities. The reliabili…

Disentangling the formation history of galaxies via population-orbit superposition: method validation

Ling Zhu, Glenn van de Ven, Ryan Leaman +9

We present population-orbit superposition models for external galaxies based on Schwarzschild's orbit-superposition method, by tagging the orbits with age and metallicity. The mode…
