Stellar-mass microlensing of gravitational waves

Mark H. Y. Cheung, Joseph Gais, Otto A. Hannuksela +1

When gravitational waves pass through the nuclear star clusters of galactic lenses, they may be microlensed by the stars. Such microlensing can cause potentially observable beating…

Response to sudden surge in human movement by an urban-adapted animal

Debottam Bhattacharjee, Anindita Bhadra

Interaction with its immediate environment determines the ecology of an organism. Species present in any habitat, wild or urban, may face extreme pressure due to sudden perturbatio…

Galaxy shape statistics in the effective field theory

Zvonimir Vlah, Nora Elisa Chisari, Fabian Schmidt

Intrinsic galaxy alignments yield an important contribution to the observed statistics of galaxy shapes. The general bias expansion for galaxy sizes and shapes in three dimensions…

Modelling nonlinear dynamics of interacting tipping elements on complex networks: the PyCascades package

Nico Wunderling, Jonathan Krönke, Valentin Wohlfarth +6

Tipping elements occur in various systems such as in socio-economics, ecology and the climate system. In many cases, the individual tipping elements are not independent from each o…

Real-time imputation of missing predictor values in clinical practice

Steven WJ Nijman, Jeroen Hoogland, T Katrien J Groenhof +6

Use of prediction models is widely recommended by clinical guidelines, but usually requires complete information on all predictors that is not always available in daily practice. W…

HateCheck: Functional Tests for Hate Speech Detection Models

Paul Röttger, Bertram Vidgen, Dong Nguyen +3

Detecting online hate is a difficult task that even state-of-the-art models struggle with. Typically, hate speech detection models are evaluated by measuring their performance on h…

Diving below the spin-down limit: Constraints on gravitational waves from the energetic young pulsar PSR J0537-6910

The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1589

We present a search for continuous gravitational-wave signals from the young, energetic X-ray pulsar PSR J0537-6910 using data from the second and third observing runs of LIGO and…

All-sky search in early O3 LIGO data for continuous gravitational-wave signals from unknown neutron stars in binary systems

The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1369

Rapidly spinning neutron stars are promising sources of persistent, continuous gravitational waves. Detecting such a signal would allow probing of the physical properties of matter…

The role of AGN on the structure, kinematics and evolution of ETGs in the Horizon simulations

M. S. Rosito, S. E. Pedrosa, P. B. Tissera +7

Feedback processes play a fundamental role in the regulation of the star formation (SF) activity in galaxies and, in particular, in the quenching of early-type galaxies (ETGs) as h…

Black Hole S-matrix for a scalar field

Panos Betzios, Nava Gaddam, Olga Papadoulaki

We describe a unitary scattering process, as observed from spatial infinity, of massless scalar particles on an asymptotically flat Schwarzschild black hole background. In order to…

Nonlinear curvature effects in gravitational waves from inspiralling black hole binaries

Banafsheh Shiralilou, Tanja Hinderer, Samaya Nissanke +2

Gravitational waves (GWs) from merging black holes allow for unprecedented probes of strong-field gravity. Testing gravity in this regime requires accurate predictions of gravitati…
