On the Detection of QCD Axion Dark Matter by Coherent Scattering

Kavli Affiliate: Satoshi Shirai | First 5 Authors: Hajime Fukuda, Satoshi Shirai, , , | Summary: The QCD axion is a promising candidate of the dark matter. In this paper, we discuss elastic scattering processes between nucleons and the QCD axion dark matter. We point out that the cross section can be enhanced by more […]

TOI 560 : Two Transiting Planets Orbiting a K Dwarf Validated with iSHELL, PFS and HIRES RVs

Kavli Affiliate: Avi Shporer | First 5 Authors: Mohammed El Mufti, Peter P. Plavchan, Howard Isaacson, Bryson L. Cale, Dax L. Feliz | Summary: We validate the presence of a two-planet system orbiting the 0.2–1.4 Gyr K4 dwarf TOI 560 (HD 73583). The system consists of an inner moderately eccentric transiting mini-Neptune (TOI 560 b, […]

A Linear Relation Between the Color Stretch $s_{BV}$ and the Rising Color Slope $s_0^*(B-V)$ of Type Ia Supernovae

Kavli Affiliate: Subo Dong | First 5 Authors: Ping Chen, Subo Dong, Chris Ashall, S. Benetti, D. Bersier | Summary: Using data from the Complete Nearby ($z_{host}<0.02$) sample of Type Ia Supernovae (CNIa0.02), we discover a linear relation between two parameters derived from the $B-V$ color curves of Type Ia supernovae: the "color stretch" $s_{BV}$ […]

Sensitivity of the Roman Coronagraph Instrument to Exozodiacal Dust

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Ewan S Douglas, John Debes, Bertrand Mennesson, Bijan Nemati, Jaren Ashcraft | Summary: Exozodiacal dust, warm debris from comets and asteroids in and near the habitable zone of stellar systems, reveals the physical processes that shape planetary systems. Scattered light from this dust is also a source […]

Primordial Black Hole Formation in Non-Minimal Curvaton Scenario

Kavli Affiliate: Misao Sasaki | First 5 Authors: Shi Pi, Misao Sasaki, , , | Summary: In the curvaton scenario, the curvature perturbation is generated after inflation at the curvaton decay, which may have a prominent non-Gaussian effect. For a model with a non-trivial kinetic term, an enhanced curvature perturbation on a small scale can […]
