Metal abundances in the MACER simulations of the hot interstellar medium
S. Pellegrini, Z. Gan, J. P. Ostriker +1
A hot plasma is the dominant phase of the interstellar medium of early-type galaxies. Its origin can reside in stellar mass losses, residual gas from the formation epoch, and accre…
Hot Gas Flows on Parsec Scale in the Low-Luminosity Active Galactic Nucleus NGC 3115
Zhiyuan Yao, Zhaoming Gan
NGC 3115 is known as the low-luminosity active galactic nucleus which hosts the nearest () billion solar mass supermassive black hole (). Its…
CHILES VI: HI and H Observations for z < 0.1 Galaxies; Probing HI Spin Alignment with Filaments in the Cosmic Web
J. Blue Bird, J. Davis, N. Luber +15
We present neutral hydrogen (HI) and ionized hydrogen (H) observations of ten galaxies out to a redshift of 0.1. The HI observations are from the first epoch (178 hours) of the…
Formation and Evolution of Compact Object Binaries in AGN Disks
Hiromichi Tagawa, Zoltan Haiman, Bence Kocsis
The astrophysical origin of gravitational wave (GW) events discovered by LIGO/VIRGO remains an outstanding puzzle. In active galactic nuclei (AGN), compact-object binaries form, ev…
Direct Detection of Black Hole-Driven Turbulence in the Centers of Galaxy Clusters
Yuan Li, Marie-Lou Gendron-Marsolais, Irina Zhuravleva +16
Supermassive black holes (SMBHs) are thought to provide energy that prevents catastrophic cooling in the centers of massive galaxies and galaxy clusters. However, it remains unclea…
The Assembly of the First Massive Black Holes
Kohei Inayoshi, Eli Visbal, Zoltán Haiman
The existence of 10^9 Msun supermassive black holes (SMBHs) within the first billion year of the universe has stimulated numerous ideas for the prompt formation and rapid…
Chemodynamics of barred galaxies in cosmological simulations: On the Milky Way's quiescent merger history and in-situ bulge
F. Fragkoudi, R. J. J. Grand, R. Pakmor +9
We explore the chemodynamical properties of a sample of barred galaxies in the Auriga magneto-hydrodynamical cosmological zoom-in simulations, which form boxy/peanut (b/p) bulges,…
Simple Yet Powerful: Hot Galactic Outflows Driven by Supernovae
Miao Li, Greg L. Bryan
Supernovae (SNe) drive multiphase galactic outflows, impacting galaxy formation; however, cosmological simulations mostly use \textit{ad hoc} feedback models for outflows, making o…
Correlations Between Black Holes and Host Galaxies in the Illustris and IllustrisTNG Simulations
Yuan Li, Melanie Habouzit, Shy Genel +11
We study black hole - host galaxy correlations, and the relation between the over-massiveness (the distance from the average relation) of super-massive black holes (SMBH…
The Influence of Black Hole Binarity on Tidal Disruption Events
Eric R. Coughlin, Philip J. Armitage, Giuseppe Lodato +1
Mergers are fundamental to the standard paradigm of galaxy evolution, and provide a natural formation mechanism for supermassive black hole binaries. The formation process of such…
The Inside-out Growth of the Galactic Disk
Neige Frankel, Jason Sanders, Hans-Walter Rix +2
We quantify the inside-out growth of the Milky Way's low-alpha stellar disk, modelling the ages, metallicities and Galactocentric radii of APOGEE red clump stars with 6 < R < 13 kp…
Tentative Detection of the Circumgalactic Medium of the Isolated Low-Mass Dwarf Galaxy WLM
Y. Zheng, M. E. Putman, A. Emerick +7
We report a tentative detection of the circumgalactic medium (CGM) of WLM, an isolated, low-mass (log), dwarf irregular galaxy in the Local Group (LG). We an…
A Statistical Solution to the Chaotic, Non-Hierarchical Three-Body Problem
Nicholas C. Stone, Nathan W. C. Leigh
The three-body problem is arguably the oldest open question in astrophysics, and has resisted a general analytic solution for centuries. Various implementations of perturbation the…
Group pre-processing versus cluster ram-pressure stripping: the case of ESO156-G029
Robert Dzudzar, Virginia Kilborn, Chandrashekar Murugeshan +3
We report on observations of ESO156-G029, member of a galaxy group which is positioned at the virial radius of cluster Abell 3193. ESO156-G029 is located ~ 1.4 Mpc in projected dis…
Making a supermassive star by stellar bombardment
Hiromichi Tagawa, Zoltan Haiman, Bence Kocsis
Approximately two hundred supermassive black holes (SMBHs) have been discovered within the first Gyr after the Big Bang. One pathway for the formation of SMBHs is through the…
NIHAO-UHD: The properties of MW-like stellar disks in high resolution cosmological simulations
Tobias Buck, Aura Obreja, Andrea V. Macciò +3
Simulating thin and extended galactic disks has long been a challenge in computational astrophysics. We introduce the NIHAO-UHD suite of cosmological hydrodynamical simulations of…
Simulating Metal Mixing of Both Common and Rare Enrichment Sources in a Low Mass Dwarf Galaxy
Andrew Emerick, Greg L. Bryan, Mordecai-Mark Mac Low
One-zone models constructed to match observed stellar abundance patterns have been used extensively to constrain the sites of nucleosynthesis with sophisticated libraries of stella…
Probing gaseous galactic halos through the rotational kSZ effect
José Manuel Zorrilla Matilla, Zoltán Haiman
The rotational kinematic Sunyaev-Zeldovich (rkSZ) signal, imprinted on the cosmic microwave background (CMB) by the gaseous halos (spinning "atmospheres") of foreground galaxies, w…
The Impact of Type Ia Supernovae in Quiescent Galaxies: II. Energetics and Turbulence
Miao Li, Yuan Li, Greg L. Bryan +2
Type Ia supernovae (SNe Ia) provide unique and important feedback in quiescent galaxies, but their impact has been underappreciated. In this paper, we analyze a series of high-reso…
The Impact of Type Ia Supernovae in Quiescent Galaxies: I. Formation of the Multiphase Interstellar medium
Miao Li, Yuan Li, Greg L. Bryan +2
A cool phase of the interstellar medium has been observed in many giant elliptical galaxies, but its origin remains unclear. We propose that uneven heating from Type Ia supernovae…
Properties of the Simulated Circumgalactic Medium
Cassandra Lochhaas, Greg L. Bryan, Yuan Li +2
The circumgalactic medium (CGM) is closely linked to galaxy formation and evolution, but difficult to characterize observationally and typically poorly resolved in cosmological sim…
Fragmentation in Population III Galaxies formed through Ionizing Radiation
Mihir Kulkarni, Eli Visbal, Greg L. Bryan
Population III stars forming in minihalos tend to be relatively inefficient, with each minihalo hosting one or a small number of stars which are more massive than local stars but s…
