Kavli Affiliate: Debora Sijacki | First 5 Authors: Leah Bigwood, Martin A. Bourne, Vid Irsic, Alexandra Amon, Debora Sijacki | Summary: While cosmological simulations of galaxy formation have reached maturity, able to reproduce many fundamental galaxy and halo properties, no consensus has yet been reached on the impact of `baryonic feedback’ on the non-linear matter […]
Kavli Affiliate: Debora Sijacki | First 5 Authors: Xihan Ji, Roberto Maiolino, Hannah Übler, Jan Scholtz, Francesco D’Eugenio | Summary: Recent observations from JWST have revealed an abundant population of active galactic nuclei (AGN) and so-called “Little Red Dots” (LRDs) at $2lesssim z lesssim 11$, many of which are characterized by V-shaped UV-to-optical continua with […]

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Qinyue Fei, John D. Sivlerman, Seiji Fujimoto, Ran Wang, Luis C. Ho | Summary: We conduct a study of the gas kinematics of two quasar host galaxies at $zgtrsim6$ traced by the [CII] emission line using ALMA. By combining deep observations at both low and high resolution, […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: William M. Baker, Francesco D’Eugenio, Roberto Maiolino, Andrew J. Bunker, Charlotte Simmonds | Summary: We use NIRSpec MSA spectroscopy and NIRCam Photometry to explore the properties of JADES-GS8-RL-1, a rapidly quenched, $z=8.5$ galaxy with a stellar mass of $10^{8.9}M_odot$, a steep blue UV slope, a Balmer break, […]
Kavli Affiliate: Blake Sherwin | First 5 Authors: Darby Kramer, Alexander van Engelen, Christopher Cain, Niall MacCrann, Hy Trac | Summary: The kinetic Sunyaev-Zel’dovich effect (kSZ) and patchy screening effect are two complementary cosmic microwave background (CMB) probes of the reionization era. The kSZ effect is a relatively strong signal, but is difficult to disentangle […]
Kavli Affiliate: Martin Haehnelt | First 5 Authors: Adam Abdalla, Mahiro Abe, Sven Abend, Mouine Abidi, Monika Aidelsburger | Summary: This summary of the second Terrestrial Very-Long-Baseline Atom Interferometry (TVLBAI) Workshop provides a comprehensive overview of our meeting held in London in April 2024, building on the initial discussions during the inaugural workshop held at […]
Kavli Affiliate: Roberto Maiolino | First 5 Authors: Alessandro Trinca, Rosa Valiante, Raffaella Schneider, Ignas Juodžbalis, Roberto Maiolino | Summary: Early JWST observations are providing growing evidence for a ubiquitous population of accreting supermassive black holes (BHs) at high redshift, many of which appear overmassive compared to the empirically-derived local scaling relation between black hole […]
Kavli Affiliate: Anthony Challinor | First 5 Authors: Erik Rosenberg, Steven Gratton, Anthony Challinor, , | Summary: Motivated by observed discrepancies between ACT DR4 and Planck 2018 cosmic microwave background (CMB) anisotropy power spectra, particularly in the cross-correlation of temperature and E-mode polarization, we investigate challenges that may be encountered in the comparison of satellite […]
