Constraints on gravitational waves from the 2024 Vela pulsar glitch
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1774
Among known neutron stars, the Vela pulsar is one of the best targets for gravitational-wave searches. It is also one of the most prolific in terms of glitches, sudden frequency ch…
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…
GWTC-4.0: Methods for Identifying and Characterizing Gravitational-wave Transients
The LIGO Scientific Collaboration, the Virgo Collaboration, the KAGRA Collaboration +1809
The Gravitational-Wave Transient Catalog (GWTC) is a collection of candidate gravitational-wave transient signals identified and characterized by the LIGO-Virgo-KAGRA Collaboration…
The Science of the Einstein Telescope
Adrian Abac, Raul Abramo, Simone Albanesi +485
Einstein Telescope (ET) is the European project for a gravitational-wave (GW) observatory of third-generation. In this paper we present a comprehensive discussion of its science ob…
Cosmological Probes of Structure Growth and Tests of Gravity
Jiamin Hou, Julian Bautista, Maria Berti +4
The current standard cosmological model is constructed within the framework of general relativity with a cosmological constant , which is often associated with dark energy, and…
Detecting the heterodyning of gravitational waves
Jakob Stegmann, Sander M. Vermeulen
Gravitational waves modulate the apparent frequencies of other periodic signals. Low-frequency gravitational waves could therefore be detected by observing frequency modulations in…
New universal property of cosmological gravitational wave anisotropies
Ameek Malhotra, Ema Dimastrogiovanni, Guillem Domènech +2
The anisotropies of the stochastic gravitational wave background, as produced in the early phases of cosmological evolution, can act as a key probe of the primordial universe parti…
The isotropic attractor solution of axion-SU(2) inflation: Universal isotropization in Bianchi type-I geometry
Ira Wolfson, Azadeh Maleknejad, Tomoaki Murata +2
SU(2) gauge fields coupled to an axion field can acquire an isotropic background solution during inflation. We study homogeneous but anisotropic inflationary solutions in the prese…
Resonant gravitational waves in dynamical Chern-Simons-axion gravity
Tomohiro Fujita, Ippei Obata, Takahiro Tanaka +1
In this paper, we consider dynamical Chern-Simons gravity with the identification of the scalar field coupled though the Pontryagin density with the axion dark matter, and we discu…
Effects of Gravitational Chern-Simons during Axion-SU(2) Inflation
Leila Mirzagholi, Eiichiro Komatsu, Kaloian D. Lozanov +1
In this paper, we examine the viability of inflation models with a spectator axion field coupled to both gravitational and SU(2) gauge fields via Chern-Simons couplings. Requiring…
Mukhanov-Sasaki equation in manifestly gauge-invariant linearized cosmological perturbation theory with dust reference fields
Kristina Giesel, Laura Herold, Bao-Fei Li +1
The aim of this article is to understand the role of dust reference fields, often also called clocks, on cosmological perturbations around a flat FLRW universe. We derive the Mukha…
How attractive is the isotropic attractor solution of axion-SU(2) inflation?
Ira Wolfson, Azadeh Maleknejad, Eiichiro Komatsu
The key to the phenomenological success of inflation models with axion and SU(2) gauge fields is the isotropic background of the SU(2) field. Previous studies showed that this isot…
