Accelerated inference of microlensed gravitational waves with machine learning
Marienza Caldarola, Srashti Goyal, Nihar Gupte +2
Gravitational waves (GWs) within the LIGO-Virgo-KAGRA sensitivity band can be microlensed by stellar and intermediate-mass black holes, producing a frequency-dependent modulation o…
Cosmo-Learn: code for learning cosmology using different methods and mock data

We present cosmo_learn, an open-source python-based software package designed to simulate cosmological data and perform data-driven inference using a range of modern statistical an…
Simulating a Gaussian stochastic gravitational wave background signal in pulsar timing arrays
Reginald Christian Bernardo, Kin-Wang Ng
We revisit the theoretical modeling and simulation of a Gaussian stochastic gravitational wave background (SGWB) signal in a pulsar timing array (PTA). We show that the correlation…
Listening Across the Cosmic Time: Standard Sirens from Ground- and Space-Based Missions in the Next Decade
Alberto Salvarese, Hsin-Yu Chen, Alberto Mangiagli +1
Precise measurement of the Hubble parameter will enable stringent tests of the standard model for cosmology. Standard sirens, using the luminosity distances measured by gravitation…
Probing Ultralight Axion-like Dark Matter: A Pulsar Timing Arrays-Pulsar Polarization Arrays Synergy
Ximeng Li, Yonghao Liu, Zu-Cheng Chen +9
Ultralight axionlike dark matter (ALDM) is a leading candidate in the dark matter realm, characterized by its prominent wave properties on astronomical scales. Pulsar timing arrays…
The Topology of Rayleigh-Levy Flights in Two Dimensions
Reginald Christian Bernardo, Stephen Appleby, Francis Bernardeau +1
Rayleigh-Lévy flights are simplified cosmological tools which capture certain essential statistical properties of the cosmic density field, including hierarchical structures in hig…
Gravitational wave lensing: probing Fuzzy Dark Matter with LISA
Shashwat Singh, Guilherme Brando, Stefano Savastano +1
Gravitational lensing is a universal phenomenon: it affects both gravitational waves (GWs) and electromagnetic signals travelling through the gravitational field of a massive objec…
Accurate pulsar timing array residual variances and correlation of the stochastic gravitational wave background
Reginald Christian Bernardo, Kin-Wang Ng
Pulsar timing arrays have reported a compelling evidence of a nanohertz stochastic gravitational wave background. However, the origin of the signal remains undetermined, largely be…
DarkGEO: A Large-Scale Laser-Interferometric Axion Detector
Joscha Heinze, Alex Gill, Artemiy Dmitriev +8
Axions and axion-like particles (ALPs) are leading candidates for dark matter. They are well motivated in many extensions of the Standard Model and supported by astronomical observ…
Searching for scalar field dark matter with LIGO
Alexandre S. Göttel, Aldo Ejlli, Kanioar Karan +4
We report on a direct search for scalar field dark matter using data from LIGO's third observing run. We analyse the coupling of size oscillations of the interferometer's beamsplit…
No-go guide for the Hubble tension: late-time or local-scale new physics
Lu Huang, Shao-Jiang Wang, Wang-Wei Yu
The standard model of modern cosmology might be cracked by the recent persistent hot debate on the Hubble-constant () tension, which manifests itself as the sound-horizon ($r_…
Massive black hole binaries in LISA: constraining cosmological parameters at high redshifts
Alberto Mangiagli, Chiara Caprini, Sylvain Marsat +3
One of the scientific objectives of the Laser Interferometer Space Antenna (LISA) is to probe the expansion of the Universe using gravitational wave observations. Indeed, as gravit…
Constraints on cosmologically coupled black holes from gravitational wave observations and minimal formation mass
Luca Amendola, Davi C. Rodrigues, Sumit Kumar +1
We test the possibility that the black holes (BHs) detected by LIGO-Virgo-KAGRA (LVK) may be cosmologically coupled and grow in mass proportionally to the cosmological scale factor…

Guilherme Brando, Kazuya Koyama, Hans A. Winther
We revisit a method to incorporate the Vainshtein screening mechanism in N-body simulations proposed by R. Scoccimarro in~\cite{Scoccimarro:2009eu}. We further extend this method t…
Gravitational wave lensing as a probe of halo properties and dark matter
Giovanni Tambalo, Miguel Zumalacárregui, Liang Dai +1
Just like light, gravitational waves (GWs) are deflected and magnified by gravitational fields as they propagate through the Universe. However, their low frequency, phase coherence…
