Forged by Feedback: Stellar Properties of Brightest Group Galaxies in Cosmological Simulations
Ruxin Barré, Arif Babul, Ghassem Gozaliasl +7
We investigate how different galaxy formation models impact the stellar properties of brightest group galaxies (BGGs) in four cosmological simulations: ROMULUS, SIMBA, SIMBA-C, and…
Figuring Out Gas & Galaxies in Enzo (FOGGIE). XV. Examining the Spatial and Kinematic Relationship between Circumgalactic Mg II and O VI
Mackenzie Ticoras, Brian W. O'Shea, Claire Kopenhafer +9
Understanding the thermodynamic properties of the circumgalactic medium (CGM) is key to uncovering the baryon cycle in galaxies. Here we present spatial and kinematic relationships…
Figuring Out Gas & Galaxies In Enzo (FOGGIE). XIV. The Observability of Emission from Accretion and Feedback in the Circumgalactic Medium with Current and Future Instruments
Vida Saeedzadeh, Jason Tumlinson, Molly S. Peeples +11
Observing the circumgalactic medium (CGM) in emission lines from ionized gas enables direct mapping of its spatial and kinematic structure, offering new insight into the gas flows…
Figuring Out Gas & Galaxies In Enzo (FOGGIE). XIII. On the Observability of Extended HI Disks and Warps
Cameron W. Trapp, Molly S. Peeples, Jason Tumlinson +6
Atomic Hydrogen (HI) is a useful tracer of gas in and around galaxies, and can be found in extended disk-like structures well beyond a system's optical extent. Here, we investigate…
FOGGIE: Figuring Out Gas & Galaxies In Enzo XII. The Formation and Evolution of Extended HI Galactic Disks and Warps with a Dynamic Circumgalactic medium
Cameron W. Trapp, Molly S. Peeples, Jason Tumlinson +8
Atomic hydrogen (HI) is an important component of gas in and around galaxies and forms extended disk-like structures well beyond the extent of starlight. Here we investigate the pr…
Figuring Out Gas & Galaxies In Enzo (FOGGIE) XI: Circumgalactic O VI Emission Traces Clumpy Inflowing Recycled Gas
Cassandra Lochhaas, Molly S. Peeples, Brian W. O'Shea +11
The circumgalactic medium (CGM) is host to gas flows into and out of galaxies and regulates galaxy growth, but the multiphase, diffuse gas in this region is challenging to observe.…
Core to Cosmic Edge: SIMBA-C's New Take on Abundance Profiles in the Intragroup Medium at z = 0
Aviv Padawer-Blatt, Zhiwei Shao, Renier T. Hough +9
We employ the SIMBA-C cosmological simulation to study the impact of its upgraded chemical enrichment model (Chem5) on the distribution of metals in the intragroup medium (IGrM). W…
Dual AGNs: Precursors of Binary Supermassive Black Hole Formation and Mergers
Vida Saeedzadeh, Arif Babul, Suvodip Mukherjee +3
The presence of dual active galactic nuclei (AGN) on scales of a few tens of kpc can be used to study merger-induced accretion on supermassive black holes (SMBHs) and offer insight…
Shining Light on the Hosts of the Nano-Hertz Gravitational Wave Sources: A Theoretical Perspective
Vida Saeedzadeh, Suvodip Mukherjee, Arif Babul +2
The formation of supermassive black holes (SMBHs) in the Universe and its role in the properties of the galaxies is one of the open questions in astrophysics and cosmology. Though,…
Cool and gusty, with a chance of rain: Dynamics of multiphase CGM around massive galaxies in the Romulus simulations
Vida Saeedzadeh, S. Lyla Jung, Douglas Rennehan +8
Using high-resolution {\sc Romulus} simulations, we explore the origin and evolution of the circumgalactic medium (CGM) in the region 0.1 $\leq \mathrm{R}/\mathrm{R}_\mathrm{500} \…
Massive central galaxies of galaxy groups in the Romulus simulations: an overview of galaxy properties at z=0
Seoyoung Lyla Jung, Douglas Rennehan, Vida Saeedzadeh +6
Contrary to many stereotypes about massive galaxies, observed brightest group galaxies (BGGs) are diverse in their star formation rates, kinematic properties, and morphologies. Stu…
