Discovery of a second-generation planet candidate accreting onto a white dwarf
Jamie T. Williams, Boris T. Gänsicke, Nicholas C. Stone +10
Many white dwarfs accrete the debris of disrupted planetary bodies, detected in the form of metal-enrichment in their atmospheres, dusty or gaseous circumstellar discs, and photome…
Parametric excitation of rotational soft modes of the buckled discrete elastic ring
Panagiotis Koutsogiannakis, Massimo Ruzzene
In the present study, we explore the existence and characteristics of a rotating vibrational mode in a discrete buckled ring that manifests under transverse harmonic forcing. The s…
Efficient LOS-Sampled GNSS Direct Position Estimation: An Information-Loss CRB Analysis
Wei Gao, Rong Yang, Jihong Huang +1
Conventional Global Navigation Satellite System (GNSS) Direct Position Estimation (DPE) exploits raw intermediate-frequency (IF) data and provides a full-information Cramér-Rao Bou…
Spatial sparse sampling-based iterative optimization framework for GNSS Direct Position Estimation
Wei Gao, Rong Yang, Jihong Huang +2
Direct position estimation (DPE), a promising technique in Global Navigation Satellite Systems (GNSS) receivers, enables estimation of position, velocity, and time (PVT) solutions…
Precision Neutron Skins of Pb and Ca from Parity-Violating Electron Scattering
PREX Collaboration, D. Adhikari, H. Albataineh +100
We have measured the parity-violating elastic electron scattering asymmetry in the PREX and CREX experiments on Pb and Ca respectively; these are both doubly-mag…
Systematic and Statistical Properties of Prominence Eruptions on the M-dwarf YZ CMi
Yuto Kajikiya, Kosuke Namekata, Yuta Notsu +4
M-dwarfs produce frequent flares, and their associated mass ejections are expected to significantly affect the habitability of close-in exoplanets. Recent spectroscopic observation…
The relationship between solar and stellar tachoclines, dynamos, and spin-down
Loren I. Matilsky, Lydia Korre, Nicholas Brummell
The solar tachocline, a thin shear layer separating the differentially rotating convective zone (CZ) from the underlying rigidly rotating radiative zone (RZ), remains a dynamical m…
Robots Influencing Humans to Reveal their Goals during Collaboration and Competition
Debasmita Ghose, Oz Gitelson, Michal Lewkowicz +3
We propose a unified strategy for fast goal inference in human-robot interaction. The core idea is to drive the human toward Critical Decision Points (CDPs)-states where competing…
ACES VII. Compact Continuum Source Catalog of the Central Molecular Zone
Jennifer Wallace, Cara Battersby, Nazar Budaiev +58
The Central Molecular Zone (CMZ) resides in the inner few hundred parsecs of our Galaxy, and despite being the largest reservoir of dense molecular gas in the Milky Way, it has a r…
The MegaWave Radio Surveyor
T. Joseph W. Lazio, Evgenya Shkolnik, James Aguirre +40
Several Decadal-level questions in astrophysics, exoplanets, astrobiology, and cosmology can be addressed only at low radio frequencies inaccessible from Earth. The MegaWave Radio…
Overmassive supermassive black holes in SDSS close galaxy pairs
Maggie C. Huber, Julia M. Comerford, Joseph Simon
Supermassive black holes (SMBHs) and their host-galaxies coevolve through channels such as hierarchical merging and AGN feedback, establishing tight scaling relations between SMBH…
Black hole singularity is a surface not a point
Andrew J. S. Hamilton, Tyler McMaken
It is widely repeated in the popular literature and elsewhere that the singularity at the center of a black hole is a point. It is not true. Two observers who free-fall into a sphe…
ChainForge: Characterizing Embedding as the Bottleneck in Quantum Annealer Workloads
Kanishka Jayathilake, Cordelia Brumley, Tanner Smith +1
Quantum Annealers (QAs) are among the first commercially scaled quantum computing systems designed for large-scale optimization. Unlike digital systems that execute sequences of co…
Large-Scale Dynamos Driven by Shear-Flow-Induced Jets
B. Tripathi, A. E. Fraser, P. W. Terry +3
At every scale they occupy, magnetic fields affect various phenomena, including star formation, cosmic ray transport, charged particle acceleration, space weather, transport in pla…
Stable Glasses of Organic Semiconductor Resist Crystallization
Kushal Bagchi, Marie E. Fiori, Camille Bishop +2
The instability of glassy solids poses a key limitation to their use in several technological applications. Well-packed organic glasses, prepared by physical vapor deposition (PVD)…
Using Deposition Rate and Substrate Temperature to Manipulate Liquid Crystal-like Order in a Vapor-deposited Hexagonal Columnar Glass
Camille Bishop, Zhenxuan Chen, Michael F. Toney +3
We investigate vapor-deposited glasses of a phenanthroperylene-ester, known to form an equilibrium hexagonal columnar phase, and show that liquid crystal-like order can be manipula…
Drone-Assisted UAV-UGV Collaboration for Autonomous Navigation in Snow-Covered Terrain
Shreyam Gupta, P. Agrawal, Priyam Gupta +1
This paper presents a collaborative UAV-UGV navigation framework for high-altitude, snow-covered terrain, where reduced visibility and unstable ground render conventional methods i…
Simultaneous Mars-orbit observations reveal Kelvin-Helmholtz instability-driven bulk atmospheric ion escape
Chi Zhang, Chuanfei Dong, Gangkai Poh +11
Atmospheric ion escape driven by the solar wind is a key process controlling the long-term loss of the Martian atmosphere. Localized plasma clouds can carry substantial fluxes of p…
From Prompt to Embodied Simulation: Using Generative AI to Create AR Physics Learning Tools
Ofek Levy, Joshua Glazer, Noah D. Finkelstein +1
Spread your thumb and index finger in the air, and a virtual lamp in the room changes color. Computer simulations have a long and well-documented record of supporting physics learn…
A Probabilistic Framework for Population Studies of the Solar Neighborhood: Application to SDSS-V and Gaia
Ilija Medan, Keivan G. Stassun, Zachary Way +8
Studies of the Solar Neighborhood require spectroscopic follow-up of stars identified in astrometric surveys to fully characterize their physical properties. The SDSS-V Solar Neigh…
