Turning Points in the Age-Metallicity Relations -- Created by Late Satellite Infall and Enhanced by Radial Migration
Yuxi Lu, Melissa K. Ness, Tobias Buck +1
The present-day Age-Metallicity Relation (AMR) is a record of the star formation history of the Galaxy, as this traces the chemical enrichment of the gas over time. We use a zoomed…
Stellar Abundance Maps of the Milky Way Disk
Anna-Christina Eilers, David W. Hogg, Hans-Walter Rix +4
To understand the formation of the Milky Way's prominent bar it is important to know whether stars in the bar differ in the chemical element composition of their birth material as…
H-alpha emission in local galaxies: star formation, time variability and the diffuse ionized gas
Sandro Tacchella, Aaron Smith, Rahul Kannan +6
The nebular recombination line H is widely used as a star-formation rate (SFR) indicator in the local and high-redshift Universe. We present a detailed H radiative transfer s…
Investigating the Baryon Cycle in Interacting Dwarfs with the Very Large Array and Pan-STARRS
Nicholas Luber, Sarah Pearson, Mary Putman +3
We present resolved HI synthesis maps from the Very Large Array (VLA) of three interacting dwarf systems: the NGC 3664 dwarf pair, the NGC 3264 dwarf pair, and the UGC 4638 dwarf t…
Event Horizon Telescope observations of the jet launching and collimation in Centaurus A
Michael Janssen, Heino Falcke, Matthias Kadler +236
Very-long-baseline interferometry (VLBI) observations of active galactic nuclei at millimeter wavelengths have the power to reveal the launching and initial collimation region of e…
Supermassive black holes in cosmological simulations II: the AGN population and predictions for upcoming X-ray missions
Melanie Habouzit, Rachel S. Somerville, Yuan Li +13
In large-scale hydrodynamical cosmological simulations, the fate of massive galaxies is mainly dictated by the modeling of feedback from active galactic nuclei (AGN). The amount of…
The physics of Lyman-alpha escape from disc-like galaxies
Aaron Smith, Rahul Kannan, Sandro Tacchella +8
Hydrogen emission lines can provide extensive information about star-forming galaxies in both the local and high-redshift Universe. We present a detailed Lyman continuum (LyC), Lym…
How Binaries Accrete: Hydrodynamic Simulations with Passive Tracer Particles
Christopher Tiede, Jonathan Zrake, Andrew MacFadyen +1
Linear analysis of gas flows around orbiting binaries suggests that a centrifugal barrier ought to clear a low-density cavity around the binary and inhibit mass transfer onto it. M…
Galaxy Formation in the Santa Cruz semi-analytic model compared with IllustrisTNG -- I. Galaxy scaling relations, dispersions, and residuals at z=0
Austen Gabrielpillai, Rachel S. Somerville, Shy Genel +4
We present the first results from applying the Santa Cruz semi-analytic model (SAM) for galaxy formation on merger trees extracted from a dark matter only version of the IllustrisT…
Neutron-capture elements record the ordered chemical evolution of the disc over time
Danny Horta, Melissa K. Ness, Jan Rybizki +2
An ensemble of chemical abundances probing different nucleosynthetic channels can be leveraged to build a comprehensive understanding of the chemical and structural evolution of th…
Probing Hot Gas Components of Circumgalactic Medium in Cosmological Simulations with the Thermal Sunyaev-Zel'dovich Effect
Junhan Kim, Sunil Golwala, James G. Bartlett +8
The thermal Sunyaev-Zel'dovich (tSZ) effect is a powerful tool with the potential for constraining directly the properties of the hot gas that dominates dark matter halos because i…
The Cosmic Ultraviolet Baryon Survey (CUBS) IV: The Complex Multiphase Circumgalactic Medium as Revealed by Partial Lyman Limit Systems
Thomas J. Cooper, Gwen C. Rudie, Hsiao-Wen Chen +18
We present a detailed study of two partial Lyman limit systems (pLLSs) of neutral hydrogen column density discovered at…
Reading the CARDs: the Imprint of Accretion History in the Chemical Abundances of the Milky Way's Stellar Halo
Emily C. Cunningham, Robyn E. Sanderson, Kathryn V. Johnston +7
In the era of large-scale spectroscopic surveys in the Local Group (LG), we can explore using chemical abundances of halo stars to study the star formation and chemical enrichment…
A Young, Low-Density Stellar Stream in the Milky Way Disk: Theia 456
Jeff J. Andrews, Jason L. Curtis, Julio Chanamé +4
Our view of the variety of stellar structures pervading the local Milky Way has been transformed by the application of clustering algorithms to the Gaia catalog. In particular, sev…
The Physical Origin and the Properties of Arm Spurs/Feathers in Local Simulations of the Wiggle Instability
Yash Mandowara, Mattia C. Sormani, Emanuele Sobacchi +1
Gaseous substructures such as feathers and spurs dot the landscape of spiral arms in disc galaxies. One of the candidates to explain their formation is the wiggle instability of ga…
Real and counterfeit cores: how feedback expands halos and disrupts tracers of inner gravitational potential in dwarf galaxies
Ethan D. Jahn, Laura V. Sales, Federico Marinacci +8
The tension between the diverging density profiles in Lambda Cold Dark Matter (CDM) simulations and the constant-density inner regions of observed galaxies is a long-standing ch…
The homogeneity of the star forming environment of the Milky Way disk over time
Melissa K. Ness, Adam J. Wheeler, Kevin McKinnon +4
Stellar abundances and ages afford the means to link chemical enrichment to galactic formation. In the Milky Way, individual element abundances show tight correlations with age, wh…
Formation and evolution of young massive clusters in galaxy mergers: the SMUGGLE view
Hui Li, Mark Vogelsberger, Greg L. Bryan +3
Galaxy mergers are known to host abundant young massive cluster (YMC) populations, whose formation mechanism is still not well-understood. Here, we present a high-resolution galaxy…
