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 […]
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 […]
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). […]
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 […]

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 […]
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 […]
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 […]
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 […]
Kavli Affiliate: E. P. S. Shellard | First 5 Authors: C. J. A. P. Martins, Patrick Peter, I. Yu. Rybak, E. P. S. Shellard, | Summary: We apply a recently developed formalism to study the evolution of a current-carrying string network under the simple but generic assumption of a linear equation of state. We demonstrate […]
