A trail of dark matter-free galaxies from a bullet dwarf collision

Pieter van Dokkum, Zili Shen, Michael A. Keim +8

The ultra-diffuse galaxies DF2 and DF4 in the NGC1052 group share several unusual properties: they both have large sizes, rich populations of overluminous and large globular cluste…

Constraining the shape of dark matter haloes with globular clusters

Marta Reina-Campos, Sebastian Trujillo-Gomez, Joel L. Pfeffer +4

We explore how diffuse stellar light and globular clusters (GCs) can be used to trace the matter distribution of their host halo using an observational methodology. For this, we us…

Examining quasar absorption-line analysis methods: the tension between simulations and observational assumptions key to modelling clouds

Rachel Marra, Christopher W. Churchill, Glenn G. Kacprzak +3

A key assumption in quasar absorption line studies of the circumgalactic medium (CGM) is that each absorption component maps to a spatially isolated "cloud" structure that has sing…

Introducing EMP-Pathfinder: modelling the simultaneous formation and evolution of stellar clusters in their host galaxies

Marta Reina-Campos, Benjamin W. Keller, J. M. Diederik Kruijssen +5

The formation and evolution of stellar clusters is intimately linked to that of their host galaxies. To study this connection, we present the EMP-Pathfinder suite of cosmological z…

The physics governing the upper truncation mass of the globular cluster mass function

Meghan E. Hughes, Joel L. Pfeffer, Nate Bastian +5

The mass function of globular cluster (GC) populations is a fundamental observable that encodes the physical conditions under which these massive stellar clusters formed and evolve…

NGC5846-UDG1: A galaxy formed mostly by star formation in massive, extremely dense clumps of gas

Shany Danieli, Pieter van Dokkum, Sebastian Trujillo-Gomez +10

It has been shown that ultra-diffuse galaxies (UDGs) have higher specific frequencies of globular clusters on average than other dwarf galaxies with similar luminosities. The UDG N…

Using cosmological simulations and synthetic absorption spectra to assess the accuracy of observationally derived CGM metallicities

Rachel Marra, Christopher W. Churchill, Caitlin Doughty +6

We used adaptive mesh refinement hydrodynamic cosmological simulations of a Milky Way-type galaxy and a Dwarf galaxy and generated synthetic quasar absorption-line spec…

Globular clusters as tracers of the dark matter halo: insights from the E-MOSAICS simulations

Marta Reina-Campos, Sebastian Trujillo-Gomez, Alis J. Deason +5

Globular clusters (GCs) are bright objects that span a wide range of galactocentric distances, and are thus probes of the structure of dark matter (DM) haloes. In this work, we exp…

The emergence of dark matter-deficient ultra-diffuse galaxies driven by scatter in the stellar mass-halo mass relation and feedback from globular clusters

Sebastian Trujillo-Gomez, J. M. Diederik Kruijssen, Marta Reina-Campos

In addition to their low stellar densities, ultra-diffuse galaxies (UDGs) have a broad variety of dynamical mass-to-light ratios, ranging from dark matter (DM) dominated systems to…

What to expect when using globular clusters as tracers of the total mass distribution in Milky Way-mass galaxies

Meghan E. Hughes, Prashin Jethwa, Michael Hilker +8

Dynamical models allow us to connect the motion of a set of tracers to the underlying gravitational potential, and thus to the total (luminous and dark) matter distribution. They a…
