A study of particle acceleration, heating, power deposition, and the damping length of kinetic Alfvén waves in non-Maxwellian coronal plasma
S. Ayaz, Gary P. Zank, Imran A. Khan +2
The heating of the solar corona and solar wind, through suprathermal particles and kinetic Alfvén waves within the 0 - 10 range, has been a subject of great interest…
Broadband study of the Be X-ray binary RX J0520.5-6932 during its outburst in 2024
H. N. Yang, C. Maitra, G. Vasilopoulos +18
A new giant outburst of the Be X-ray binary RX J0520.5-6932 was detected and subsequently observed with several space-borne and ground-based instruments. This study presents a comp…
Inferred Hubble Parameter from Gravitational Waves in a Perturbative Bianchi I Background
Kevin J. Ludwick, Peter L. Williams
It is straightforward to take the gravitational wave solution to first order in far from a binary source in a Minkowski background and adapt it to the Friedmann-Lemaitre-Robe…
ESO 137-001 -- a jellyfish galaxy model
B. Vollmer, M. Sun, P. Jachym +2
Ram pressure stripping of the spiral galaxy ESO 137-001 within the highly dynamical intracluster medium (ICM) of the Norma cluster lead to spectacular extraplanar CO, optical, H…

Aaron C. Trigg, Rachael Stewart, Alex Van Kooten +22
We present the detection and analysis of GRB 231115A, a candidate extragalactic magnetar giant flare (MGF) observed by Fermi/GBM and localized by INTEGRAL to the starburst galaxy M…
Measuring the ICM velocity structure within the A3266 galaxy cluster
E. Gatuzz, J. Sanders, A. Liu +7
We present a detailed analysis of the velocity structure of the hot intracluster medium (ICM) within the A3266 galaxy cluster, including new observations taken between June and Nov…
Addressing Data Heterogeneity in Federated Learning of Cox Proportional Hazards Models
Navid Seidi, Satyaki Roy, Sajal K. Das +1
The diversity in disease profiles and therapeutic approaches between hospitals and health professionals underscores the need for patient-centric personalized strategies in healthca…
Centroiding Undersampled PSFs with a Lookup Table
Kevin J. Ludwick, Ashley Mazingo
We present a method of centroiding undersampled point spread functions (PSFs) that may be useful, especially when dithering is not an option. If the profile of the expected PSF is…
Optimized Receiver Design for Entanglement-Assisted Communication using BPSK
Rahul Bhadani, Ivan B. Djordjevic
The use of pre-shared entanglement in entanglement-assisted communication offers a superior alternative to classical communication, especially in the photon-starved regime and high…
The interface of gravity and dark energy
Kristen Lackeos, Richard Lieu
At sufficiently large radii dark energy modifies the behavior of (a) bound orbits around a galaxy and (b) virialized gas in a cluster of galaxies. Dark energy also provides a natur…
High-resolution imaging of the evolving bipolar outflows in symbiotic novae: The case of the RSOphiuchi 2021 nova outburst
R. Lico, M. Giroletti, U. Munari +6
The recurrent and symbiotic nova RS Ophiuchi (RSOph) underwent a new outburst phase during August 2021, about 15 years after the last event that occurred in 2006. This outburst rep…
Interstellar Neutral Hydrogen in the Heliosphere: New Horizons Observations in the Context of Models
P. Swaczyna, M. Bzowski, K. Dialynas +12
Interstellar neutral (ISN) hydrogen is the most abundant species in the outer heliosheath and the very local interstellar medium (VLISM). Charge exchange collisions in the outer he…
The Camera and Readout for the Trinity Demonstrator and the EUSO-SPB2 Cherenkov Telescope
Mahdi Bagheri, Srikar Gadamsetty, Eliza Gazda +9
We developed a modular silicon photomultiplier camera to detect Earth-skimming PeV to EeV tau neutrinos with the imaging atmospheric Cherenkov technique. We built two cameras, a 25…
The EUSO-SPB2 Fluorescence Telescope for the Detection of Ultra-High Energy Cosmic Rays
James H. Adams, Denis Allard, Phillip Alldredge +79
The Extreme Universe Space Observatory on a Super Pressure Balloon 2 (EUSO-SPB2) flew on May 13 and 14 of 2023. Consisting of two novel optical telescop…
Accounting for Clock-Induced Charge Production in the EMCCD Gain Register
Kevin Ludwick
An electron-multiplying charge-coupled device (EMCCD) is often used for taking images with space telescopes and other devices. Photons hit the pixels and photo-electrons are create…
Going Beyond the MHD Approximation: Physics-Based Numerical Solution of the CGL Equations
Deepak Bhoriya, Dinshaw S. Balsara, Vladimir Florinski +1
We present a new numerical model for solving the Chew-Goldberger-Low system of equations describing a bi-Maxwellian plasma in a magnetic field. Heliospheric and geospace environmen…
The binding of cosmological structures by massless topological defects
Richard Lieu
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field equations sourced by a topological defect, \ie~a singularity o…
