A Hierarchical Shock Model of Ultra-High-Energy Cosmic Rays
Paul Simeon, Noémie Globus, Kirk S. S. Barrow +1
We propose that a hierarchical shock model$\unicode{x2014}$including supernova remnant shocks, galactic wind termination shocks, and accretion shocks around cosmic filaments and ga…
The First Billion Years, According to JWST
Angela Adamo, Hakim Atek, Micaela B. Bagley +46
With stunning clarity, JWST has revealed the Universe's first billion years. The scientific community is analyzing a wealth of JWST imaging and spectroscopic data from that era, an…
The AGORA High-resolution Galaxy Simulations Comparison Project IV: Halo and Galaxy Mass Assembly in a Cosmological Zoom-in Simulation at
Santi Roca-Fàbrega, Ji-hoon Kim, Joel R. Primack +25
In this fourth paper from the AGORA Collaboration, we study the evolution down to redshift and below of a set of cosmological zoom-in simulations of a Milky Way mass galaxy b…
The AGORA High-resolution Galaxy Simulations Comparison Project. VI. Similarities and Differences in the Circumgalactic Medium
Clayton Strawn, Santi Roca-Fàbrega, Joel R. Primack +26
We analyze the circumgalactic medium (CGM) for eight commonly-used cosmological codes in the AGORA collaboration. The codes are calibrated to use identical initial conditions, cosm…
A Hierarchical Framework for explaining the Cosmic Ray Spectrum using Diffusive Shock Acceleration
Roger Blandford, Paul Simeon, Noémie Globus +3
The hypothesis that the entire cosmic ray spectrum, from to energy, can be accounted for by diffusive shock acceleration on increasin…
The Galaxy Assembly and Interaction Neural Networks (GAINN) for high-redshift JWST observations
Lillian Santos-Olmsted, Kirk Barrow, Tilman Hartwig
We present the Galaxy Assembly and Interaction Neural Networks (GAINN), a series of artificial neural networks for predicting the redshift, stellar mass, halo mass, and mass-weight…
JWST reveals a possible galaxy merger in triply-lensed MACS0647JD
Tiger Yu-Yang Hsiao, Dan Coe, Abdurro'uf +63
MACS0647JD is a triply-lensed galaxy originally discovered with the Hubble Space Telescope. Here we report new JWST imaging, which clearly resolves MACS0647JD as ha…
The Lyman Continuum Escape Survey: Connecting Time-Dependent [OIII] and [OII] Line Emission with Lyman Continuum Escape Fraction in Simulations of Galaxy Formation
Kirk S. S. Barrow, Brant E. Robertson, Richard S. Ellis +4
Escaping Lyman continuum photons from galaxies likely reionized the intergalactic medium at redshifts . However, the Lyman continuum is not directly observable at these…
Blue galaxies: modelling nebular He II emission in high redshift galaxies
Kirk S. S. Barrow
Using cosmological simulations to make useful, scientifically relevant emission line predictions is a relatively new and rapidly evolving field. However, nebular emission lines hav…
Induced metal-free star formation around a massive black hole seed
Aycin Aykutalp, Kirk S. S. Barrow, John H. Wise +1
The direct formation of a massive black hole is a potential seeding mechanism of the earliest observed supermassive black holes. We investigate how the existence of a massive black…
Observational signatures of massive black hole formation in the early universe
Kirk S. S. Barrow, Aycin Aykutalp, John H. Wise
Space telescope observations of massive black holes during their formation may be key to understanding the origin of supermassive black holes and high-redshift quasars. To create d…
First Light II: Emission Line Extinction, Population III Stars, and X-ray Binaries
Kirk S. S. Barrow, John H. Wise, Aycin Aykutalp +3
We produce synthetic spectra and observations for metal-free stellar populations and high mass X-ray binaries in the Renaissance Simulations at a redshift of 15. We extend our meth…
First Light: exploring the Spectra of High-Redshift Galaxies in the Renaissance Simulations
Kirk S. S. Barrow, John H. Wise, Michael L. Norman +2
We present synthetic observations for the first generations of galaxies in the Universe and make predictions for future deep field observations for redshifts greater than 6. Due to…
