Kavli Affiliate: Sara Seager | First 5 Authors: TRAPPIST-1 JWST Community Initiative, :, Julien de Wit, René Doyon, Benjamin V. Rackham | Summary: Ultra-cool dwarf stars are abundant, long-lived, and uniquely suited to enable the atmospheric study of transiting terrestrial companions with JWST. Amongst them, the most prominent is the M8.5V star TRAPPIST-1 and its […]
Kavli Affiliate: George Efstathiou | First 5 Authors: Rajesh Mondal, Rennan Barkana, Anastasia Fialkov, , | Summary: The 21-cm signal from the dark ages is a powerful tool for fundamental cosmology and for probing new physics. While it can be used for precision measurements within standard cosmology, here we study two non-standard models: an excess […]
Kavli Affiliate: George Efstathiou | First 5 Authors: Rajesh Mondal, Rennan Barkana, Anastasia Fialkov, , | Summary: The dark ages 21-cm signal is a powerful tool for precision cosmology and probing new physics. We study two non-standard models: an excess radio background (ERB) model (possibly generated by dark matter decay) and the millicharged dark matter […]
Kavli Affiliate: Igor V. Moskalenko | First 5 Authors: Igor V. Moskalenko, , , , | Summary: The last two decades have brought spectacular advances in astrophysics of cosmic rays (CRs) and space- and ground-based astronomy. Launches of missions that employ forefront detector technologies enabled measurements with large effective areas, wide fields of view, and […]
Kavli Affiliate: Huawei Zhang | First 5 Authors: Weixiang Sun, Yang Huang, Han Shen, Chun Wang, Huawei Zhang | Summary: We present a comprehensive study of the kinematic properties of the different Galactic disk populations, as defined by the chemical abundance ratios and stellar ages, across a large disk volume (4.5 $leq$ R $leq$ 15.0 […]

Kavli Affiliate: David Spergel | First 5 Authors: Pablo Lemos, Liam Parker, ChangHoon Hahn, Shirley Ho, Michael Eickenberg | Summary: We present the first simulation-based inference (SBI) of cosmological parameters from field-level analysis of galaxy clustering. Standard galaxy clustering analyses rely on analyzing summary statistics, such as the power spectrum, $P_ell$, with analytic models based […]
Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Nick Ekanger, Shunsaku Horiuchi, Hiroki Nagakura, Samantha Reitz, | Summary: The sensitivity of current and future neutrino detectors like Super-Kamiokande (SK), JUNO, Hyper-Kamiokande (HK), and DUNE is expected to allow for the detection of the diffuse supernova neutrino background (DSNB). However, the DSNB model ingredients like the […]
