Search for continuous gravitational waves from neutron stars in five globular clusters in the first part of the fourth LIGO-Virgo-KAGRA observing run

Damon H. T. Cheung, Keith Riles, Rafel Amengual +15

We present the results of directed searches for continuous gravitational waves from unknown neutron stars in five Milky Way globular clusters. We carry out these searches in the LI…

Parameter estimation for the GWTC-4.0 catalog with phenomenological waveform models that include orbital eccentricity and an updated description of spin precession

Yumeng Xu, Jorge Valencia, Héctor Estellés Estrella +11

The GWTC-4.0 catalog of transient gravitational wave signals describes observations made in the first part of the fourth observing run of the LIGO-Virgo-KAGRA (LVK) gravitational w…

Defining eccentricity for spin-precessing binaries

Md Arif Shaikh, Vijay Varma, Antoni Ramos-Buades +4

Standardizing the definition of eccentricity is necessary for unambiguous inference of the orbital eccentricity of compact binaries from gravitational wave observations. In previou…

A numerical approach to particle creation in accelerating toy models

Pedro Duarte Baptista, Alex Vañó-Viñuales, Adrían del Río

The formation of black holes by the gravitational collapse of stars is known to spontaneously excite particle pairs out of the quantum vacuum. For the canonical vacuum state at pas…

Hyperboloidal neutron star and black hole initial data in spherical symmetry

Alex Vañó-Viñuales

The focus of this work is on the construction of initial data including a neutron star on a hyperboloidal slice. As simplest scenario for this first step, spherical symmetry is con…
