Up, Up, and Away? Quantifying ISM Fallback using Ram Pressure Stripping Simulations
Harrison J. Souchereau, Stephanie Tonnesen, Jingyao Zhu +1
The paper uses hydrodynamical wind‑tunnel simulations of a dwarf galaxy in a Coma‑like cluster to study how cold interstellar gas cycles between outflow and inflow (fallback) durin…
The Role of Cluster Environments in Quiescent Galaxy Stellar Halo Assembly
Devin J. Williams, Ivana Damjanov, Marcin Sawicki +6
External interactions drive galaxy stellar mass growth and morphological evolution. As stellar haloes-assembled largely via hierarchical accretion-preserve signatures of these proc…
Kinematic Confirmation of a Remarkable Linear Trail of Galaxies in the NGC 1052 Field, Consistent with Formation in a High-Speed Bullet Dwarf Collision
Michael A. Keim, Pieter van Dokkum, Zili Shen +6
A unique linear trail of diffuse galaxies was recently identified in the NGC 1052 field. This trail includes the remarkable, ultra-diffuse galaxies DF2 and DF4 which lack dark matt…
ALMA-JELLY I: High Resolution CO(2-1) Observations of Ongoing Ram Pressure Stripping in NGC 4858 Reveal Asymmetrical Gas Tail Formation and Fallback
Harrison J. Souchereau, Jeffrey D. P. Kenney, Pavel Jachym +13
We present new CO(2-1) observations (resolution pc) of the Coma cluster jellyfish galaxy NGC 4858 obtained from the ALMA-JELLY large program. Analyzing this data alon…
The Growth of Galaxy Stellar Haloes Over
Devin J. Williams, Ivana Damjanov, Marcin Sawicki +9
Galaxies are predicted to assemble their stellar haloes through the accretion of stellar material from interactions with their cosmic environment. Observations that trace stellar h…
