Imaging X-ray Polarimetry Explorer
Brian Ramsey, Paolo Soffitta, Martin C. Weisskopf
In 1971 a group from Columbia University detected polarized X rays from the Crab Nebula at about 3 sigma level during a short sounding rocket flight (Novick et al. (1972)). This me…
X-ray polarization of Z-type neutron star low-mass X-ray binaries -- II. Spectropolarimetric analysis
Andrea Gnarini, Francesco Ursini, Giorgio Matt +8
IXPE has provided for the first time detailed energy- and time-resolved X-ray polarimetry of Z-type neutron star low-mass X-ray binaries (NS-LMXBs) as they move along their color-c…
General Relativistic Shock Wave Solutions with Black Hole Formation: The Singular Isothermal Sphere Case
Chien-Ting J. Chen, Michael J. Cai, Fabio Pacucci
The rapid emergence at of ubiquitous populations of supermassive black holes (SMBHs) revealed by JWST and of quasars with estimated masses $M_\bullet > 10^{10} M_\odot…
Science of High Resolution X-ray Imaging
H. L. Marshall, K. Weaver, M. Schattenburg +34
This report summarizes potential studies of the Hi-ReX Science Analysis Group for an Ultra-High Angular Resolution X-ray Observatory. Many potential science cases are presented, sp…
The performance of the TA4 surface detector array: 4.3 years of the first-half expansion
Telescope Array Collaboration, R. U. Abbasi, T. Abu-Zayyad +126
The Telescope Array (TA) experiment aims to reveal the origin of ultra-high-energy cosmic rays (UHECRs) by observing air showers using surface detectors (SDs), which spread over an…
Advancing Heliophysics and Space Weather Modeling through Open Science
C. Corti, M. M. Kuznetsova, M. A. Reiss +85
We present a community-wide effort to develop a strategy and action plan to advance heliophysics and space weather modeling through open science. While open science has the potenti…
IXPE Polarizations of the Lighthouse Pulsar, Trail, and Filament
Jack T. Dinsmore, Roger W. Romani, S. Zhang +9
The Lighthouse pulsar (PSR J11016101) sports a bright X-ray trail and filament. The synchrotron emission from both structures is expected to be polarized, with electric vector p…
A Statistical Survey of Faint Solar X-ray Transients Observed by NuSTAR
Reed B. Masek, Lindsay Glesener, Jessie Duncan +14
In this paper, we use a highly sensitive telescope to characterize solar X-ray transients ranging from microflares in active regions down to weakly energetic brightenings in the qu…
Collaborative Agent Reasoning Engineering (CARE): A Three-Party Design Methodology for Systematically Engineering AI Agents with Subject Matter Experts, Developers, and Helper Agents
Rahul Ramachandran, Nidhi Jha, Muthukumaran Ramasubramanian
We present Collaborative Agent Reasoning Engineering (CARE), a disciplined methodology for engineering Large Language Model (LLM) agents in scientific domains. Unlike ad-hoc trial-…
X-Ray Polarization from the Atoll 4U 1735-44 Suggests a Low Inclination
M. A. Díaz Teodori, A. Bobrikova, A. Gnarini +17
X-ray polarimetry is a new tool capable of probing the geometry of accretion onto weakly magnetized neutron stars. Here we present the first X-ray spectropolarimetric results from…
IXPE view of the Crab pulsar following the 17 July and 6 August 2025 glitches
Paolo Soffitta, Niccolò Bucciantini, Josephine Wong +19
The Crab pulsar experienced two relatively small glitches separated by only 20 days in September and October 2025. IXPE observed the source twice, with delay times since the glitch…
Where within the 3C 84 jet are -rays produced?
Georgios F. Paraschos, Ioannis Liodakis, Svetlana Jorstad +49
The location of -ray creation and emission within extra-galactic jets is a matter of active debate. One particularly well-suited source to pinpoint the location is the nearby, b…
Observations of a Twin Pair of Atypical Solar Flares and a Magnetic-reconnection Scenario
Satyam Agarwal, Alphonse C. Sterling, Shibu K. Mathew +3
We present observations and a magnetic-reconnection scenario of a twin pair of "atypical flares" that occurred on 2022 April 22 in a quadrupolar magnetic configuration formed by tw…
