Blandford-Znajek jets in galaxy formation simulations: exploring the diversity of outflows produced by spin-driven AGN jets in Seyfert galaxies

Kavli Affiliate: Debora Sijacki | First 5 Authors: Rosie Y. Talbot, Debora Sijacki, Martin A. Bourne, , | Summary: Recent observations of Seyfert galaxies indicate that low power, misaligned jets can undergo significant interaction with the gas in the galactic disc and may be able to drive large-scale, multiphase outflows. We apply our novel sub-grid […]

Effect of the cosmological transition to metal-enriched star-formation on the hydrogen 21-cm signal

Kavli Affiliate: George Efstathiou | First 5 Authors: Mattis Magg, Itamar Reis, Anastasia Fialkov, Rennan Barkana, Ralf S. Klessen | Summary: Mapping Cosmic Dawn with 21-cm tomography offers an exciting new window into the era of primordial star formation. However, self-consistent implementation of both the process of star formation and the related 21-cm signal is […]

What drives the scatter of local star-forming galaxies in the BPT diagrams? A Machine Learning based analysis

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Mirko Curti, Connor Hayden-Pawson, Roberto Maiolino, Francesco Belfiore, Filippo Mannucci | Summary: We investigate which physical properties are most predictive of the position of local star forming galaxies on the BPT diagrams, by means of different Machine Learning (ML) algorithms. Exploiting the large statistics from the Sloan […]

Momentum deposition of supernovae with cosmic rays

Kavli Affiliate: Debora Sijacki | First 5 Authors: Francisco Rodríguez Montero, Sergio Martin-Alvarez, Debora Sijacki, Adrianne Slyz, Julien Devriendt | Summary: The cataclysmic explosions of massive stars as supernovae are one of the key ingredients of galaxy formation. However, their evolution is not well understood in the presence of magnetic fields or cosmic rays (CRs). […]

A disturbing FABLE of mergers, feedback and mass biases

Kavli Affiliate: Debora Sijacki | First 5 Authors: Jake S Bennett, Debora Sijacki, , , | Summary: The use of galaxy clusters as cosmological probes often relies on understanding the properties and evolution of the intracluster medium (ICM). However, the ICM is a complex plasma, regularly stirred by mergers and feedback, with non-negligible bulk and […]

Assessing the sources of reionisation: a spectroscopic case study of a 30$times$ lensed galaxy at $z sim 5$ with Lyα, CIV, MgII, and [NeIII]

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Joris Witstok, Renske Smit, Roberto Maiolino, Mirko Curti, Nicolas Laporte | Summary: We present a detailed spectroscopic analysis of a galaxy at $z simeq 4.88$ that is, by chance, magnified $sim 30 times$ by gravitational lensing. Only three sources at $z gtrsim 5$ are known with such […]

The extension of the Fundamental Metallicity Relation beyond the BPT star-forming sequence: evidence for both gas accretion and starvation

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Nimisha Kumari, Roberto Maiolino, James Trussler, Filippo Mannucci, Giovanni Cresci | Summary: The fundamental metallicity relation (FMR) of galaxies is a 3D relation between the gas-phase metallicity, stellar mass and star-formation rate (SFR). It has been studied so far only for galaxies identified as star-forming (SF) on […]

Malaise and remedy of binary boson-star initial data

Kavli Affiliate: Ulrich Sperhake | First 5 Authors: Thomas Helfer, Ulrich Sperhake, Robin Croft, Miren Radia, Bo-Xuan Ge | Summary: Through numerical simulations of boson-star head-on collisions, we explore the quality of binary initial data obtained from the superposition of single-star spacetimes. Our results demonstrate that evolutions starting from a plain superposition of individual boosted […]

HERA Phase I Limits on the Cosmic 21-cm Signal: Constraints on Astrophysics and Cosmology During the Epoch of Reionization

Kavli Affiliate: George Efstathiou | First 5 Authors: The HERA Collaboration, Zara Abdurashidova, James E. Aguirre, Paul Alexander, Zaki Ali | Summary: Recently, the Hydrogen Epoch of Reionization Array (HERA) collaboration has produced the experiment’s first upper limits on the power spectrum of 21-cm fluctuations at z~8 and 10. Here, we use several independent theoretical […]
