Kavli Affiliate: Tom Abel | Summary:We investigate how differences in the stellar feedback produce disks with different morphologies in Milky Way-like progenitors over 1 $leq z leq 5$, using eight state-of-the-art cosmological hydrodynamics simulation codes in the textitAGORA project. In three of the participating codes, a distinct, rotation-dominated inner core emerges with a formation timescale […]

Kavli Affiliate: Eric Charles | First 5 Authors: The RAIL Team, Jan Luca van den Busch, Eric Charles, Johann Cohen-Tanugi, Alice Crafford | Summary: Virtually all extragalactic use cases of the Vera C. Rubin Observatory’s Legacy Survey of Space and Time (LSST) require the use of galaxy redshift information, yet the vast majority of its […]

Kavli Affiliate: Eric Charles | First 5 Authors: The RAIL Team, The RAIL Team, , , | Summary: Virtually all extragalactic use cases of the Vera C. Rubin Observatory’s Legacy Survey of Space and Time (LSST) require the use of galaxy redshift information, yet the vast majority of its sample of tens of billions of […]

Kavli Affiliate: Chao-Lin Kuo | First 5 Authors: J. A. Zebrowski, C. L. Reichardt, A. J. Anderson, B. Ansarinejad, M. Archipley | Summary: We present a measurement of the $B$-mode polarization power spectrum of the cosmic microwave background anisotropies at 32 $le$ $ell$ $<$ 502 for three bands centered at 95, 150, and 220 GHz […]

Kavli Affiliate: Zeeshan Ahmed | Summary:We develop randomized quantum algorithms to simulate quantum collision models, also known as repeated interaction schemes, which provide a rich framework to model various open-system dynamics. The underlying technique involves composing time evolutions of the total (system, bath, and interaction) Hamiltonian and intermittent tracing out of the environment degrees of […]

Kavli Affiliate: Andrew Rasmussen| First 5 Authors: M. Benedikt, M. Benedikt, , , | Summary:Volume 1 of the FCC Feasibility Report presents an overview of the physics case, experimental programme, and detector concepts for the Future Circular Collider (FCC). This volume outlines how FCC would address some of the most profound open questions in particle […]

Kavli Affiliate: Andrew Rasmussen| First 5 Authors: M. Benedikt, M. Benedikt, , , | Summary:Volume 3 of the FCC Feasibility Report presents studies related to civil engineering, the development of a project implementation scenario, and environmental and sustainability aspects. The report details the iterative improvements made to the civil engineering concepts since 2018, taking into […]

Kavli Affiliate: Nicola Omodei | Summary:In the multimessenger era, the association of high-energy transients with their $γ$-ray counterparts can be obscured by magnetized large-scale structure surrounding the source. We analyze models for delayed off-axis $γ$-rays, arising from the injection of ultrahigh-energy cosmic rays ($Egtrsim 10^18$ eV) and $γ$-rays ($varepsilon_γgtrsim10^18$ eV), and very-high-energy $γ$-rays ($varepsilon_γgtrsim 100$ […]

Kavli Affiliate: Vahe Petrosian | Summary:We investigate the cosmological evolution of the luminosity and redshift of FRBs. As is the case for all extragalactic sources, we are dealing with data that are truncated by observational selection effects, the most important being the flux limit, which introduces the so-called Eddington-Malmquist bias. In addition, for FRBs, there […]

Kavli Affiliate: Risa H. Wechsler | First 5 Authors: Christian Aganze, Vedant Chandra, Risa H. Wechsler, Ting S. Li, Sergey E. Koposov | Summary: The census of stellar streams and dwarf galaxies in the Milky Way provides direct constraints on galaxy formation models and the nature of dark matter. The DESI Milky Way survey (with […]
