Kavli Affiliate: Kiyoshi Masui | First 5 Authors: CHIME Collaboration, Mandana Amiri, Kevin Bandura, Tianyue Chen, Meiling Deng | Summary: We present a detection of 21-cm emission from large-scale structure (LSS) between redshift 0.78 and 1.43 made with the Canadian Hydrogen Intensity Mapping Experiment (CHIME). Radio observations acquired over 102 nights are used to construct […]
Kavli Affiliate: Sara Seager | First 5 Authors: Néstor Espinoza, Enric Pallé, Jonas Kemmer, Rafael Luque, José A. Caballero | Summary: We report the discovery and characterization of TOI-1759~b, a temperate (400 K) sub-Neptune-sized exoplanet orbiting the M~dwarf TOI-1759 (TIC 408636441). TOI-1759 b was observed by TESS to transit on sectors 16, 17 and 24, […]
Kavli Affiliate: Alexander P. Ji | First 5 Authors: Li-Hsin Chen, Mattis Magg, Tilman Hartwig, Simon C. O. Glover, Alexander P. Ji | Summary: We study the stellar mass-to-halo mass relation at $z=0$ in 30 Milky Way-like systems down to the ultra-faint ($M_* < 10^5 M_odot$) regime using the semi-analytic model A-SLOTH. A new model […]
Kavli Affiliate: Claudio Ricci | First 5 Authors: Nikita Kamraj, Murray Brightman, Fiona A. Harrison, Daniel Stern, Javier A. García | Summary: The corona is an integral component of Active Galactic Nuclei (AGN) which produces the bulk of the X-ray emission above 1–2 keV. However, many of its physical properties and the mechanisms powering this […]
Kavli Affiliate: Mohammad Mirhosseini | First 5 Authors: Alkim Bozkurt, Chaitali Joshi, Mohammad Mirhosseini, , | Summary: Optomechanical crystals provide coupling between phonons and photons by confining them to commensurate wavelength-scale dimensions. We present a new concept for designing optomechanical crystals capable of achieving unprecedented coupling rates by confining optical and mechanical waves to deep […]
Kavli Affiliate: Kristin A. Persson | First 5 Authors: Jimmy-Xuan Shen, Haoming Howard Li, Ann Rutt, Matthew K. Horton, Kristin A. Persson | Summary: To accelerate the development of novel ion-conducting materials, we present a general graph-theoretic analysis framework for ion migration in any crystalline structure. The nodes of the graph represent metastable sites of […]
Kavli Affiliate: Steven Allen | First 5 Authors: Eric D. Miller, Catherine E. Grant, Marshall W. Bautz, Silvano Molendi, Ralph Kraft | Summary: The Wide Field Imager (WFI) flying on Athena will usher in the next era of studying the hot and energetic Universe. WFI observations of faint, diffuse sources will be limited by uncertainty […]

Kavli Affiliate: Adam Mantz | First 5 Authors: Xuejian Shen, Thejs Brinckmann, David Rapetti, Mark Vogelsberger, Adam Mantz | Summary: We perform cosmological zoom-in simulations of $19$ relaxed cluster-mass haloes with the inclusion of adiabatic gas in the cold dark matter (CDM) and self-interacting dark matter (SIDM) models. These clusters are selected as dynamically relaxed […]
