The MOND Depth Index and Dynamical Maturity Clock: Toward a Universal Classification of Galaxies and Star Clusters

Robin Eappen, Pavel Kroupa

Mass discrepancies in galaxies are empirically known to appear only below a characteristic acceleration scale a0. Here we show that this behaviour is not limited to galaxies: it ex…

Model-Independent Inference of Galaxy Star Formation Histories in the Local Volume

Robin Eappen, Pavel Kroupa

Understanding the diversity of star formation histories (SFHs) of galaxies is key to reconstructing their evolutionary paths. Traditional models often assume parametric forms such…

Growth of black holes at the centre of early-type galaxies in MOND

Robin Eappen, Pavel Kroupa

The formation of supermassive black holes (SMBHs) in early-type galaxies (ETGs) is a key challenge for galaxy formation theories. Using the monolithic collapse models of ETGs forme…

Scaling relations of early-type galaxies in MOND

Robin Eappen, Pavel Kroupa

We investigate the shape and morphology of early-type galaxies (ETGs) within the framework of Modified Newtonian Dynamics (MOND). Building on our previous studies, which demonstrat…

The XMM Cluster Survey: Automating the estimation of hydrostatic mass for large samples of galaxy clusters I -- Methodology, Validation, & Application to the SDSSRM-XCS sample

D. J. Turner, P. A. Giles, A. K. Romer +16

We describe features of the X-ray: Generate and Analyse (XGA) open-source software package that have been developed to facilitate automated hydrostatic mass () measu…

The formation of compact massive relic galaxies in MOND

Robin Eappen, Pavel Kroupa

Compact massive relic galaxies are a class of galaxies that exhibit characteristics suggesting they have remained largely unchanged since their initial formation, making them 'reli…

The formation of early-type galaxies through monolithic collapse of gas clouds in Milgromian gravity

Robin Eappen, Pavel Kroupa, Nils Wittenburg +2

Studies of stellar populations in early-type galaxies (ETGs) show that the more massive galaxies form earlier and have a shorter star formation history (SFH). In this study, we inv…
