From Giant Envelopes to Rapidly Contracting Cores in Rotating Population III Stars from to
Devesh Nandal, John Chisholm, Daniel J. Whalen +4
Population III (Pop III) stars link the chemical enrichment of the early Universe to the formation of the first massive black holes, yet their evolution remains poorly understood a…
Tracing the evolution of galaxy environments with manifold learning
Ana Sofía M. Uzsoy, Claire Lamman, Peixin Zhu +1
We present SONDE (SOrted Neighbor Distance Embedding): a scalable manifold learning approach to create a nuanced, continuous, low-dimensional representation of the geometry of gala…
The assembly history of NGC 1365 through chemical archaeology
Lisa J. Kewley, Kathryn Grasha, Alex Garcia +8
Galaxies build through infalling gas and galaxy mergers. Tracking the dynamical history of a galaxy from a single snapshot in time is notoriously difficult. We show that the dynami…
Common Excitation Patterns of Star Formation, Active Galactic Nuclei, and Shocks in Seyfert Galaxies
Peixin Zhu, Lisa J. Kewley, Dominika Ł. Król +6
The growth of galaxies and their central supermassive black holes is closely connected, yet the net effect of active galactic nuclei (AGN) feedback on host-galaxy star formation re…
The Mass Dependence of the Fundamental Metallicity Relation in Observations and Simulations
Laura Carnevale, Alex M. Garcia, Paul Torrey +8
The metal content of galaxies provides direct insight into the underlying physical processes that drive galaxy evolution. An example of this is the three-parameter relationship bet…
A quasar hatching from a buried red phase at z = 3.7
Zheng Ma, Yongda Zhu, Zhiyuan Ji +21
We present JADES-GS 209777, previously cataloged as CANDELS J033238.02-274626.2, hereafter "the Hatchling," a red quasar at . While the source has been reported in earlier…
The Small-scale Structures in the Wind of Messier 82
Yucheng Guo, Timothy Heckman, Sanchayeeta Borthakur +10
Small-scale multiphase structure plays a central role in galactic-wind evolution, yet the parsec-scale morphology and excitation of the warm ionised gas remain poorly constrained.…
Active Galactic Nuclei-driven Metallicity Enrichment in the Interstellar Medium of Mrk 573
D. Ł. Król, P. Zhu, G. Fabbiano +5
We present the first spatially resolved at pc scale application of AGN-specific metallicity diagnostics for the nearby Compton-thick Seyfert 2 galaxy Mrk 573 ()…
The Nature of Nitrogen Enhanced High Redshift Galaxies
Peixin Zhu, James Trussler, Lisa J. Kewley
Recent JWST observations have revealed a population of high-redshift galaxies () exhibiting unexpectedly bright ultraviolet (UV) nitrogen emission lines. The strong N II…
Only Nitrogen-Enhanced Galaxies Have Detectable UV Nitrogen Emission Lines at High Redshift
Peixin Zhu, Lisa J. Kewley, Tiger Yu-Yang Hsiao +1
The detections of bright UV nitrogen emission lines in some high-redshift galaxies suggest unexpectedly high nitrogen-to-oxygen ratios () compared to loca…
Metallicity Gradients in Modern Cosmological Simulations II: The Role of Bursty Versus Smooth Feedback at High-Redshift
Alex M. Garcia, Paul Torrey, Aniket Bhagwat +22
The distribution of gas-phase metals within galaxies encodes the impact of stellar feedback on galactic evolution. At high-redshift, when galaxies are rapidly assembling, feedback-…
CLASSY XII: Nitrogen Enrichment Shaped by Gas Density and Feedback
Karla Z. Arellano-Córdova, Danielle A. Berg, Matilde Mingozzi +25
We investigate the chemical evolution of N/O using a sample of 45 local star-forming galaxies (SFGs) from the CLASSY survey. This sample spans a wide range of galaxy properties, wi…
A Theoretical Three-Dimensional Diagram to Separate Star Formation, Active Galactic Nuclei, and Shocks in Galaxies
Peixin Zhu, Lisa J. Kewley, Ralph S. Sutherland +1
The excitation sources in galaxies are frequently mixed due to AGN and stellar feedback, including star formation, active galactic nuclei (AGNs), and shock excitation. Disentanglin…
The Cosmic Evolution Early Release Science Survey (CEERS)
Steven L. Finkelstein, Micaela B. Bagley, Pablo Arrabal Haro +96
We present the Cosmic Evolution Early Release Science (CEERS) Survey, a 77.2 hour Director's Discretionary Early Release Science Program. CEERS demonstrates, tests, and validates e…
Theoretical Diagnostics for Narrow Line Regions of Active Galactic Nuclei
Peixin Zhu, Lisa J. Kewley, Ralph Sutherland
Gas metallicity, ionization parameter, and gas pressure can affect the observed ratios of specific strong emission lines within galaxies. While the theoretical strong lines diagnos…
