MOA-2020-BLG-108Lb: A Giant Planet Beyond the Snow Line of a Low-Mass Lens Near the Lower Boundary of the Mass-Ratio Desert
Yuki K. Satoh, David P. Bennett, Takahiro Sumi +21
We present an analysis of the microlensing event MOA-2020-BLG-108, which was discovered in June 2020 by the MOA collaboration toward the Galactic bulge. The observed light curve sh…
Directional Cluster Migration Driven by Escape-Rate Asymmetry in Multi-Compartment Granular Systems
Kai Kono, Hiroyuki Ebata, Shio Inagaki
Granular materials are inherently out-of-equilibrium systems due to energy dissipation through inelastic collisions and friction. When driven by mechanical agitation such as vibrat…
The line modulations of H-like Fe, Ca, Ar, and S observed with /Resolve in Cyg X-3
Tomohiro Hakamata, Hirokazu Odaka, Ryota Tomaru +13
Cygnus X-3, hosting a Wolf-Rayet (WR) star whose dense wind produces various spectral lines due to photoionization by X-rays from a compact object, provides an ideal laboratory for…
A XRISM Study of Highly Ionized Iron Emission Lines from the Low-Eddington-ratio AGN in NGC 7213
Kaito Murakami, Taiki Kawamuro, Ryota Tomaru +10
We present an analysis of XRISM and NuSTAR data obtained for the nearby low-Eddington active galactic nucleus NGC 7213. Our goal is to examine whether its He-like and H-like iron e…
Refined Constraints on the Hard X-ray Polarization of the Crab Pulsar and Nebula Derived from an Extended XL-Calibur Dataset
Matthew G. Baring, Jacob Casey, Sohee Chun +26
We present updated hard X-ray polarization measurements of the Crab pulsar and nebula obtained with the balloon-borne polarimeter XL-Calibur in the ~19-64 keV energy range. During…
Anomalous phonon dispersion near yielding in athermal crystals
Fumiaki Nakai, Michio Otsuki, Kuniyasu Saitoh +1
Vibrational properties of ordered athermal solids near yielding remain poorly understood. We show that yielding in a sheared crystal is governed not by a single localized instabili…
