Probing the Hot X-ray Corona around the Massive Spiral Galaxy, NGC 6753, Using Deep XMM-Newton observations
Akos Bogdan, Herve Bourdin, William R. Forman +4
X-ray emitting gaseous coronae around massive galaxies are a basic prediction of galaxy formation models. Although the coronae around spiral galaxies offer a fundamental test of th…
Galaxies with Shells in the Illustris Simulation: Metallicity Signatures
Ana-Roxana Pop, Annalisa Pillepich, Nicola C. Amorisco +1
Stellar shells are low surface brightness arcs of overdense stellar regions, extending to large galactocentric distances. In a companion study, we identified 39 shell galaxies in a…
The Size Evolution of Star-forming and Quenched Galaxies in the IllustrisTNG simulation
Shy Genel, Dylan Nelson, Annalisa Pillepich +8
We analyze scaling relations and evolution histories of galaxy sizes in TNG100, part of the IllustrisTNG simulation suite. Observational qualitative trends of size with stellar mas…
The uniformity and time-invariance of the intra-cluster metal distribution in galaxy clusters from the IllustrisTNG simulations
Mark Vogelsberger, Federico Marinacci, Paul Torrey +8
The distribution of metals in the intra-cluster medium encodes important information about the enrichment history and formation of galaxy clusters. Here we explore the metal conten…
Unveiling the Role of the Magnetic Field at the Smallest Scales of Star Formation
Charles L. H. Hull, Philip Mocz, Blakesley Burkhart +7
We report ALMA observations of polarized dust emission from the protostellar source Ser-emb 8 at a linear resolution of 140 au. Assuming models of dust-grain alignment hold, the ob…
Radiative effects during the assembly of direct collapse black holes
Aaron Smith, Fernando Becerra, Volker Bromm +1
We perform a post-processing radiative feedback analysis on a 3D ab initio cosmological simulation of an atomic cooling halo under the direct collapse black hole (DCBH) scenario. W…
