Axion-like Particle Detection in Alkali-Noble-Gas Haloscopes

Kavli Affiliate: Jia Liu | First 5 Authors: Xiaofei Huang, Xiaolin Ma, Lei Cong, Wei Ji, Jia Liu | Summary: Revealing the essence of dark matter (DM) and dark energy is essential for understanding our universe. Ultralight (rest energy $<$10 eV) bosonic particles, including pseudoscalar axions and axion-like particles (ALPs) have emerged among leading candidates […]

DeepSurveySim: Simulation Software and Benchmark Challenges for Astronomical Observation Scheduling

Kavli Affiliate: Brian Nord | First 5 Authors: Maggie Voetberg, Brian Nord, , , | Summary: Modern astronomical surveys have multiple competing scientific goals. Optimizing the observation schedule for these goals presents significant computational and theoretical challenges, and state-of-the-art methods rely on expensive human inspection of simulated telescope schedules. Automated methods, such as reinforcement learning, […]

Cosmological gravitational particle production and its implications for cosmological relics

Kavli Affiliate: Edward W. Kolb | First 5 Authors: Edward W. Kolb, Andrew J. Long, , , | Summary: Cosmological gravitational particle production (CGPP) is the creation of particles in an expanding universe due solely to their gravitational interaction. These particles can play an important role in the cosmic history through their connection to various […]

A unified accretion disc model for supermassive black holes in galaxy formation simulations: method and implementation

Kavli Affiliate: Debora Sijacki | First 5 Authors: Sophie Koudmani, Rachel S. Somerville, Debora Sijacki, Martin A. Bourne, Yan-Fei Jiang | Summary: It is well established that supermassive black hole (SMBH) feedback is crucial for regulating the evolution of massive, if not all, galaxies. However, modelling the interplay between SMBHs and their host galaxies is […]
