Directional Search for Persistent Gravitational Waves: Results from the First Part of LIGO-Virgo-KAGRA's Fourth Observing Run

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1765

The angular distribution of gravitational-wave power from persistent sources may exhibit anisotropies arising from the large-scale structure of the Universe. This motivates directi…

Every negative amphichiral knot is rationally slice

Alessio Di Prisa, Jaewon Lee, Oğuz Şavk

In 2009, Kawauchi proved that every strongly negative amphichiral knot is rationally slice. However, as shown by Hartley in 1980, there are examples of negative amphichiral knots t…

A simple criterion for identifying slow-fast relaxation oscillations

Lucas MacQuarrie, Pei Yu

Simple conditions have been developed in [Zhang, Wahl and Yu, SIAM Rev. 2014; Yu and Wang, Math. Biosci. Eng. 2019], which are used to identify the existence of slow-fast relaxatio…

GW250114: testing Hawking's area law and the Kerr nature of black holes

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1785

The gravitational-wave signal GW250114 was observed by the two LIGO detectors with a network matched-filter signal-to-noise ratio of 80. The signal was emitted by the coalescence o…

Exponentially slow Mixing arising from Entropic Repulsion in $p$ -SOS model

Seokun Choi

We investigate the Glauber dynamics of the generalized (2+1)-dimensional $p$ -SOS model, $1 < p < \infty$ , under a hard floor constraint. This constraint induces entropic repulsion: the…

GW230814: investigation of a loud gravitational-wave signal observed with a single detector

The LIGO Scientific Collaboration, The Virgo Collaboration, The Kagra Collaboration +1783

GW230814, detected by the LIGO Livingston observatory with a signal-to-noise ratio of 42.4, represents the loudest gravitational-wave signal in the GWTC-4.0 catalog. Its source is…

All-sky search for long-duration gravitational-wave transients in the first part of the fourth LIGO-Virgo-KAGRA Observing run

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1772

We present an all-sky search for long-duration gravitational waves (GWs) from the first part of the LIGO-Virgo-KAGRA fourth observing run (O4), called O4a and comprising data taken…

Human-Guided Shade Artifact Suppression in CBCT-to-MDCT Translation via Schrödinger Bridge with Conditional Diffusion

Sung Ho Kang, Hyun-Cheol Park

We present a novel framework for CBCT-to-MDCT translation, grounded in the Schrodinger Bridge (SB) formulation, which integrates GAN-derived priors with human-guided conditional di…

Residual Connection-Enhanced ConvLSTM for Lithium Dendrite Growth Prediction

Hosung Lee, Byeongoh Hwang, Dasan Kim +1

The growth of lithium dendrites significantly impacts the performance and safety of rechargeable batteries, leading to short circuits and capacity degradation. This study proposes…

Leveraging cross-detector parameter consistency measures to enhance sensitivities of gravitational wave searches

Sayantan Ghosh, Leigh Smith, Jiyoon Sun +3

All-sky searches for generic short-duration astrophysical GW transients are often challenging because of noise transients. Developing novel signal-noise discriminators is crucial f…

On decoupling and restriction estimates

Changkeun Oh

In this short note, we prove that the restriction conjecture for the (hyperbolic) paraboloid in $R^{d}$ implies the $l^{p}$ -decoupling theorem for the (hyperbolic) paraboloid…

The probability of almost all eigenvalues being real for the elliptic real Ginibre ensemble

Gernot Akemann, Sung-Soo Byun, Yong-Woo Lee

We investigate real eigenvalues of real elliptic Ginibre matrices of size $n$ , indexed by the parameter of asymmetry $τ \in [0, 1]$ . In both the strongly and weakly non-Hermitian reg…

A Hopf index for isotropic sections of orthogonal bundles

Martijn Kool, Jeongseok Oh, Jørgen Vold Rennemo +1

The Hopf index equates the multiplicity of a zero of a section of a vector bundle with a winding number. We give eight analogues for isotropic sections of bundles with quadratic fo…

Convex cocompact groups in real hyperbolic spaces with limit set a Pontryagin sphere

Sami Douba, Gye-Seon Lee, Ludovic Marquis +1

We exhibit two examples of convex cocompact subgroups of the isometry groups of real hyperbolic spaces with limit set a Pontryagin sphere: one generated by $50$ reflections of $\ma…
