Search for Axion-Like Particles from Nearby Pre-Supernova Stars
Saurabh Mittal, Thomas Siegert, Francesca Calore +7
Axion-like particles (ALPs) are hypothetical pseudoscalar bosons that arise in many extensions of the Standard Model and are well-motivated dark matter candidates. Nearby massive s…
Quark-model search for compact pentaquark states
Emiko Hiyama, Atsushi Hosaka, Makoto Oka +1
A potential quark model is used to search for a , pentaquark state that has recently been observed experimentally by the LHCb collabora…
Chlorine and Potassium Enrichment in the Cassiopeia A Supernova Remnant
XRISM collaboration
The elements in the universe are synthesized primarily in stars and supernovae, where nuclear fusion favors the production of even-Z elements. In contrast, odd-Z elements are less…
Nuclear Responses to Two-Body External Fields Studied with the Second Random-Phase-Approximation
Futoshi Minato
This study investigates nuclear responses to two body external fields, interpreted as double phonon excitations, within the subtracted second random phase approximation (SSRPA) for…
An introduction to monitored quantum systems and quantum trajectories: spectrum, typicality, and phases
Ryusuke Hamazaki, Ken Mochizuki, Hisanori Oshima +1
Thanks to recent experimental advances in simulating and detecting quantum dynamics with high precision and controllability, our understanding of the physics of monitored quantum s…
Thermal liquid-gas phase transition in a quasi-one-dimensional dipolar Fermi gas
Lanxuan Gao, Koki Takayama, Hiroyuki Tajima +2
We theoretically investigate the thermodynamic properties of a quasi-one-dimensional single-component dipolar Fermi gas at finite temperatures. A self-bound fermionic droplet can b…
Mass-imbalance effect on the cluster formation in a one-dimensional Fermi gas with coexistent - and -wave interactions
Yixin Guo
We consider the mass-imbalance effect on the clustering in a one-dimensional two-component Fermi gas with coexistent even- and odd-wave interactions resulting in different configur…
Accuracy and Applicability of the Hartle-Thorne and Komatsu-Eriguchi-Hachisu Methods for Modeling Rotating Neutron Stars
Hyukjin Kwon, Kenta Yoshimura, Tsuyoshi Miyatsu +2
Neutron stars, which are composed of extremely dense nuclear matter, serve as natural laboratories to study nuclear interactions beyond the terrestrial experiments. Recent research…
The First Star-by-star -body/Hydrodynamics Simulation of Our Galaxy Coupling with a Surrogate Model
Keiya Hirashima, Michiko S. Fujii, Takayuki R. Saitoh +9
A major goal of computational astrophysics is to simulate the Milky Way Galaxy with sufficient resolution down to individual stars. However, the scaling fails due to some small-sca…
XRISM constraints on the velocity power spectrum in the Coma cluster
D. Eckert, M. Markevitch, J. A. ZuHone +6
The velocity field of intracluster gas in galaxy clusters contains key information on the virialization of infalling material, the dissipation of AGN energy into the surrounding me…
Mapping the Perseus Galaxy Cluster with XRISM: Gas Kinematic Features and their Implications for Turbulence
Congyao Zhang, Irina Zhuravleva, Annie Heinrich +19
In this paper, we present extended gas kinematic maps of the Perseus cluster by combining five new XRISM/Resolve pointings observed in 2025 with four Performance Verification datas…
Unlocking the initial neutron density distribution from the two-pion HBT correlation function in heavy-ion collisions
Pengcheng Li, Manzi Nan, Haojie Zhang +8
Revealing the neutron density distribution in the nucleus is one of the crucial tasks of nuclear physics. Within the framework of the ultrarelativistic quantum molecular dynamic mo…
The beta decay of Tz=-2 64Se and its descendants: the T=2 isobaric multiplet
P. Aguilera, F. Molina, B. Rubio +49
In this paper we present our results on the decay of 64Se. It is the heaviest Tz=-2 nucleus that both beta decays and has a stable mirror partner Tz=+2, thus allowing comparison wi…
One-pion exchange potential in a strong magnetic field
Daiki Miura, Masaru Hongo, Hidetoshi Taya +1
We derive the one-pion exchange potential (OPEP) in the presence of a homogeneous magnetic field using chiral perturbation theory with nonrelativistic nucleons. Our approach is app…
Exact WKB method for radial Schrödinger equation
Okuto Morikawa, Shoya Ogawa
We revisit exact WKB quantization for radial Schrödinger problems from the modern resurgence perspective, with emphasis on how ``physically meaningful'' quantization paths should b…
Revisiting the limits on dark matter annihilation cross-section and decay lifetime in light of electron and positron fluxes
Nagisa Hiroshima, Kazunori Kohri, Partha Kumar Paul +1
We revisit the upper bound on the annihilation cross-section, of a stable dark matter (DM) of mass GeV by considering five different channels: $W^+…
FewBodyToolkit.jl: a Julia package for solving quantum few-body problems
Lucas Happ
Few-body physics explores quantum systems of a small number of particles, bridging the gap between single-particle and many-body regimes. To provide an accessible tool for such stu…
Imaging the positron annihilation line with 20 years of INTEGRAL/SPI observations
Hiroki Yoneda, Thomas Siegert, Saurabh Mittal
The e e annihilation line at 511 keV provides a unique probe for studying the distribution and origin of positrons in our Galaxy. The SPI spectrometer on INTEGRAL has obser…
Stratified wind from a super-Eddington X-ray binary is slower than expected
