The First Detection of Gravitational Waves
Universe, 2017 This article deals with the first detection of gravitational waves by the advanced Laser Interferometer Gravitational Wave Observatory (LIGO) detectors on 14 September 2015, where the signal was generated by two stellar mass black holes with masses 36

Gravitational wave denoising of binary black hole mergers with deep learning
Physics Letters B, 2020 Gravitational wave detection requires an in-depth understanding of the physical properties of gravitational wave signals, and the noise from which they are extracted.

Gravitational Wave Direct Detection does not Constrain the Tensor Spectral Index at CMB Scales
The Open Journal of Astrophysics, 2021 I discuss constraints on the power spectrum of primordial tensor perturbations from a combination of Cosmic Microwave Background (CMB) measurements and the gravitational wave direct detection experiments LIGO/Virgo and DECIGO. There are two main points: (

The Fermi GBM and LAT follow-up of GW150914
EPJ Web of Conferences, 2017 As the first detection of Gravitation Wave (GW) event arising from the coalescence of two stellar-mass Black Holes (BH) was announced by LIGO, a new era for astronomy began.

GW200105 and GW200115 are compatible with a scenario of primordial black hole binary coalescences
European Physical Journal C: Particles and Fields, 2022 Two gravitational wave events, i.e. GW200105 and GW200115, were observed by the Advanced LIGO and Virgo detectors recently. In this work, we show that they can be explained by a scenario of primordial black hole binaries that are formed in the early ...

The updated DESGW processing pipeline for the third LIGO/VIRGO observing run [PDF]
EPJ Web of Conferences, 2020 The DESGW group seeks to identify electromagnetic counterparts of gravitational wave events seen by the LIGO-VIRGO network, such as those expected from binary neutron star mergers or neutron star-black hole mergers.

Mind and Cosmos as Throughput Systems: A Convergence Through the Throughput Model
Systems Research and Behavioral Science, EarlyView.ABSTRACT This paper advances a conceptual and mathematical foundations approach by applying the throughput model (TPM) to cosmic phenomena, reframing the universe as an extended information processing system. TPM's four stages, Perception, Information, Judgement and Decision Choice, are reformulated in explicit information‐theoretic and dynamical ...

Axion Black Hole Solution in Non‐Metricity Gravity
Fortschritte der Physik, Volume 74, Issue 2, February 2026.Abstract A static, spherically symmetric black hole solution in symmetric teleparallel (non‐metricity) gravity sourced by an axion field is constructed. Starting from the modified field equations, exact configurations are obtained characterized by the mass M$M$ and an axion–geometry coupling β$\beta$, with temporal metric function A(r)=1−2Mr+βr$A(r)=1-\

Journal of Physics: Conference Series, 2008 LIGO successfully acquired more than one year of three-way coincident observation data using all three detectors during its fifth science run from November 2005 to the end of September 2007. All detectors reached sensitivity better than the design. For the two 4km detectors, the all-sky averaged detection range exceeded 15 Mpc with a signal-to-noise ...
