Constraints on multifield inflation from the BOSS galaxy survey

Giovanni Cabass, Mikhail M. Ivanov, Oliver H. E. Philcox, Marko Simonovic, Matias Zaldarriaga

Summary: This study uses redshift-space galaxy clustering data from the BOSS survey to constrain local primordial non-Gaussianity (LPNG). The results show no evidence for primordial non-Gaussianity. The addition of the bispectrum analysis tightens the constraints and breaks degeneracies with non-Gaussian galaxy bias.

Black holes in galaxies: Environmental impact on gravitational-wave generation and propagation

Vitor Cardoso, Kyriakos Destounis, Francisco Duque, Rodrigo Panosso Macedo, Andrea Maselli

Summary: The study presents a family of solutions describing asymptotically flat black holes with hair and a regular horizon, useful for constraining the surrounding environment of astrophysical black holes using gravitational-wave or electromagnetic observations. The main properties of the geometry, including corrections induced by external matter and fluxes from orbiting particles, are computed for future characterization with upcoming observatories.

Geometrization of light bending and its application to SdS w spacetime

Zhen Zhang

Summary: The mysterious dark energy remains one of the greatest puzzles of modern science, and its spacetime effects can be locally described by the SdS( w ) metric. Understanding these local effects exactly is an essential step toward the direct probe of dark energy. Through mathematical and conceptual analysis, it has been proven that dark energy can exert a repulsive dark force on astrophysical scales, which is different from the Newtonian attraction of both visible and dark matter.

Reactor antineutrino anomaly in light of recent flux model refinements

C. Giunti, Y. F. Li, C. A. Ternes, Z. Xin

Summary: This study investigates the reactor antineutrino anomaly in light of recent reactor flux models obtained with conversion and summation methods. The results show that the predictions of the Kurchatov Institute (KI) conversion model and the Estienne-Fallot (EF) summation model are consistent with the reactor rates and fuel evolution data, leading to a plausible solution to the reactor antineutrino anomaly.

Summary: The Laser Interferometer Space Antenna (LISA) is an innovative experiment for gravitational wave astronomy, offering unique opportunities to address key astrophysical questions in a novel way. By synergizing with ground-based and space-born instruments, LISA enables multi-messenger observations, enhancing its discovery potential. This review highlights the extensive landscape of astrophysical theory, numerical simulations, and astronomical observations necessary for modeling and interpreting LISA's upcoming datastream. It also discusses open issues, gaps in understanding, and potential research avenues that LISA can contribute to in combination with electromagnetic domain studies.

Isotropization of locally rotationally symmetric Bianchi-I universe in f(Q)-gravity

Avik De, Sanjay Mandal, J. T. Beh, Tee-How Loo, P. K. Sahoo

Summary: This study is based on a new theory of gravity and explores the early evolution of the universe. The research finds that the universe exhibits an anisotropic spatial geometry and may contain anisotropic fluid during its early phase. However, as time goes on and due to inflation, the universe tends to become isotropic, leading to the disappearance of anisotropy in the fluid.

Primordial gravitational waves from NANOGrav: A broken power-law approach

Micol Benetti, Leila L. Graef, Sunny Vagnozzi

Summary: This study revisits the possibility that the stochastic common-spectrum process detected by the NANOGrav pulsar timing array experiment could be due to primordial gravitational waves. By considering a broken power-law parametrization for the stochastic gravitational wave background (SGWB) spectrum, the authors find that this phenomenological model is able to explain the NANOGrav signal while remaining consistent with a variety of cosmological and gravitational wave observations. Further exploration of connections to specific well-motivated early-Universe models is warranted.

Doubly heavy tetraquarks in an extended chromomagnetic model

Xin-Zhen Weng, Wei-Zhen Deng, Shi-Lin Zhu

Summary: Using an extended chromomagnetic model, the masses of doubly heavy tetraquarks are systematically studied, revealing the dominance of color-triplet configurations in the ground states. It is found that the importance of color-triplet configurations increases with the mass difference between quarks and antiquarks. Three stable states below the pseudoscalar meson thresholds are identified.

Entanglement phase structure of a holographic BCFT in a black hole background

Hao Geng, Andreas Karch, Carlos Perez-Pardavila, Suvrat Raju, Lisa Randall, Marcos Riojas, Sanjit Shashi

Summary: In this study, we compute holographic entanglement entropy for subregions of a BCFT thermal state living on a nongravitating black hole background. We find that entanglement islands do not exist when the brane lies below a critical angle at zero temperature, but they do exist at finite temperature in the context of a black string, restricted to a finite connected region on the brane called the atoll. The behavior of entanglement entropy depends on two parameters - the size of the subregion and the brane angle.

Impact of the CDF W-mass anomaly on two Higgs doublet model

Yongtae Heo, Dong-Won Jung, Jae Sik Lee

Summary: In this study, the implication of the recent CDF W-mass anomaly is considered within the framework of the two Higgs doublet model. It is found that the large deviation of the Sand T parameters from their SM values leads to an upper limit of about 1 TeV on the heavy charged and neutral Higgs bosons.

Full-shape cosmology analysis of the SDSS-III BOSS galaxy power spectrum using an emulator-based halo model: A 5% determination of σ8

Yosuke Kobayashi, Takahiro Nishimichi, Masahiro Takada, Hironao Miyatake

Summary: In this study, the authors present the results of their cosmology analysis based on the redshift-space power spectra of galaxy samples from the SDSS-III BOSS DR12 galaxy catalog. They use an emulator built from N-body simulations to compute the redshift-space power spectrum of halos, and model the galaxy-halo connection using the halo occupation distribution. The authors validate their analysis pipeline using mock catalogs of BOSS-like galaxies and find that their model reproduces the observed power spectra well. They obtain values for cosmological parameters such as Omega(m), H-0, and sigma(8) that are consistent with the Planck CMB results.

Dynamics of binary systems to fourth Post-Minkowskian order from the effective field theory approach

Christoph Dlapa, Gregor Kaelin, Zhengwen Liu, Rafael A. Porto

Summary: This paper investigates the contribution of potential interactions to the dynamics of non-spinning binaries at fourth Post-Minkowskian order. By computing the scattering angle and deriving the bound radial action, the authors analyze the effects of potential interactions using the effective field theory approach. The results are consistent with recent findings from scattering amplitudes and align with the state-of-the-art in Post-Newtonian theory.

Field sources for Simpson-Visser spacetimes

Kirill A. Bronnikov, Rahul Kumar Walia

Summary: Simpson-Visser (SV) spacetimes are the simplest modifications of black hole solutions in general relativity, connecting black holes and traversable wormholes. This study shows that any static, spherically symmetric SV metric can be obtained as a solution to the Einstein field equations with a combination of a scalar field and a magnetic field. The specific forms of the metrics are presented for Schwarzschild-like and Reissner-Nordsrom-like cases.

Post-Newtonian gravitational and scalar waves in scalar-Gauss-Bonnet gravity

Banafsheh Shiralilou, Tanja Hinderer, Samaya M. Nissanke, Nestor Ortiz, Helvi Witek

Summary: This paper models the gravitational wave emission of inspiralling binaries in scalar Gauss-Bonnet gravity theories, providing ready-to-implement gravitational wave and scalar waveforms as well as conducting a parameter space study. The study emphasizes the crucial role of black hole scalar charges in the detectability of deviation from general relativity, laying important foundations for future precision tests of gravity.
