Kavli Affiliate: Anthony Challinor | First 5 Authors: Íñigo Zubeldia, Boris Bolliet, Anthony Challinor, William Handley, | Summary: The abundance of galaxy clusters as a function of mass and redshift is a well-established and powerful cosmological probe. Cosmological analyses based on galaxy cluster number counts have traditionally relied on explicitly computed likelihoods, which are often […]

Kavli Affiliate: George Efstathiou | First 5 Authors: Peter H. Sims, Harry T. J. Bevins, Anastasia Fialkov, Dominic Anstey, Will J. Handley | Summary: Observations of the Epoch of Reionization (EoR) have the potential to answer long-standing questions of astrophysical interest regarding the nature of the first luminous sources and their effects on the intergalactic […]

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Ignas Juodžbalis, Roberto Maiolino, William M. Baker, Emma Curtis Lake, Jan Scholtz | Summary: The depth and coverage of the first years of JWST observations have revealed low luminosity active galactic nuclei (AGN) across a wide redshift range, shedding light on black hole (BH) assembly and feedback. […]

Kavli Affiliate: R. G. McMahon | First 5 Authors: Frédéric Dux, Martin Millon, Aymeric Galan, Eric Paic, Cameron Lemon | Summary: We present new time delays, the main ingredient of time delay cosmography, for 22 lensed quasars resulting from high-cadence r-band monitoring on the 2.6 m ESO VLT Survey Telescope and Max-Planck-Gesellschaft 2.2 m telescope. […]

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Seunghwan Lim, Sandro Tacchella, Roberto Maiolino, Joop Schaye, Matthieu Schaller | Summary: Exploiting a large sample of 5.3 million galaxies with $M_ast,{=},10^{10-11},{rm M}_odot$ from the highest-resolution FLAMINGO simulation, we carry out a statistical analysis of quiescent and star-forming galaxies to explore quenching mechanisms. From redshift $z,{simeq},7$ to […]

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Pierluigi Rinaldi, Pablo G. Pérez-González, George H. Rieke, Jianwei Lyu, Francesco D’Eugenio | Summary: We present a comprehensive analysis of the MIRI Extremely Red Object Virgil, a Lyman-$alpha$ emitter at $z_{spec} = 6.6379 pm 0.0035$ with the photometric properties of a Little Red Dot. Leveraging new JWST/MIRI […]

Kavli Affiliate: George Efstathiou | First 5 Authors: Boyuan Liu, Daniel Kessler, Thomas Gessey-Jones, Jiten Dhandha, Anastasia Fialkov | Summary: The first generation of stars, known as Population III (Pop III), played a crucial role in the early Universe through their unique formation environment and metal-free composition. These stars can undergo chemically homogeneous evolution (CHE) […]
