Tracking the evolution of satellite galaxies: mass stripping and dark-matter deficient galaxies
Antonio D. Montero-Dorta, Facundo Rodriguez, M. Celeste Artale +2
Satellite galaxies undergo a variety of physical processes when they are accreted by groups and clusters, often resulting in the loss of baryonic and dark matter (DM) mass. In this…
The formation of the brightest cluster galaxy and intracluster light in cosmological N-body simulations with the Galaxy Replacement Technique
Kyungwon Chun, Jihye Shin, Rory Smith +2
We investigate the formation channels of the intracluster light (ICL) and the brightest cluster galaxy (BCG) in clusters at . For this, we perform multi-resolution cosmologica…
Properties of Globular Clusters in Galaxy Clusters: Sensitivity from the Formation and Evolution of Globular Clusters
So-Myoung Park, Jihye Shin, Rory Smith +1
We investigate the properties of globular clusters in a galaxy cluster, using the particle tagging method with a semi-analytical approach in a cosmological context. We assume globu…
The First Fall is the Hardest: The Importance of Peculiar Galaxy Dynamics at Infall Time for Tidal Stripping Acting at the Centers of Groups and Clusters
Rory Smith, Paula Calderon-Castillo, Jihye Shin +2
Using dark matter only N-body cosmological simulations, we measure the pericentre distance of dark matter halos on their first infall into group and cluster halos. We find that the…
Unexpected dancing partners: Tracing the coherence between the spin and motion of dark matter halos
Yigon Kim, Rory Smith, Jihye Shin
A recent study conducted using CALIFA survey data (Lee et al, 2019b) has found that the orbital motions of neighbor galaxies are coherent with the spin direction of a target galaxy…
A New Method to Constrain the Appearance and Disappearance of Observed Jellyfish Galaxy Tails
Rory Smith, Jong-Ho Shinn, Stephanie Tonnesen +11
We present a new approach to observationally constrain where the tails of Jellyfish (JF) galaxies in groups and clusters first appear and how long they remain visible with respect…
Spatial distribution of dark matter in and around galaxy clusters traced by galaxies, gas and intracluster stars in a simulated universe
Jihye Shin, Jong Chul Lee, Ho Seong Hwang +5
To understand how well galaxies, gas and intracluster stars trace dark matter in and around galaxy clusters, we use the IllustrisTNG cosmological hydrodynamical simulation and comp…
Comparison of spatial distributions of Intracluster light and Dark Matter
Jaewon Yoo, Jongwan Ko, Cristiano G. Sabiu +7
In a galaxy cluster, the relative spatial distributions of dark matter, member galaxies, gas, and intracluster light (ICL) may connote their mutual interactions over the cluster ev…
Brought to Light III: Colors of Disk and Clump Substructures in Dwarf Early-Type Galaxies of the Fornax Cluster
Josefina Michea, Anna Pasquali, Rory Smith +3
It has been well established that dwarf early-type galaxies (ETGs) can often exhibit a complex morphology, whereby faint spiral arms, bars, edge-on disks or clumps are embedded in…
Orbital dynamics and extreme scattering event properties from long-term scintillation observations of PSR J1603-7202
Kris Walker, Daniel J. Reardon, Eric Thrane +1
We model long-term variations in the scintillation of binary pulsar PSR J16037202, observed by the 64 m Parkes radio telescope (Murriyang) between 2004 and 2016. We find that th…
Post-starburst galaxies in the centers of intermediate redshift clusters
Ariel Werle, Bianca Poggianti, Alessia Moretti +17
We present results from MUSE spatially-resolved spectroscopy of 21 post-starburst galaxies in the centers of 8 clusters from to . We measure spatially resolved…
Deep follow-up for gravitational-wave inference: a case study with GW151226
Avi Vajpeyi, Rory Smith, Eric Thrane
New analyses of gravitational wave events raise questions about the nature of some events. For example, LIGO--Virgo--KAGRA initially determined GW151226 to be a merger with a mass-…
Linking the rates of neutron star binaries and short gamma-ray bursts
Nikhil Sarin, Paul D. Lasky, Francisco H. Vivanco +4
Short gamma-ray bursts are believed to be produced by both binary neutron star (BNS) and neutron star-black hole (NSBH) mergers. We use current estimates for the BNS and NSBH merge…
