Search algorithm for a gravitational wave signal in association with Gamma Ray Burst GRB030329 using the LIGO detectors [PDF]

, 2004
One of the brightest Gamma Ray Burst ever recorded, GRB030329, occurred during the second science run of the LIGO detectors. At that time, both interferometers at the Hanford, WA LIGO site were in lock and acquiring data.

Peccei-Quinn phase transition at LIGO

Journal of High Energy Physics, 2020
The LIGO observatories can potentially detect stochastic gravitational waves arising from phase transitions which happened in the early universe at temperatures around T ∼ 108 GeV.

Impact of Teachers With Research Experiences: Student Gains in STEM Career Awareness, Perception of Value of STEM Learning, and Persistence in STEM Course Tasks

Science Education, Volume 109, Issue 3, Page 769-795, May 2025.
ABSTRACT Research Experiences for Teachers (RET) programs are a burgeoning approach to engage teachers in STEM (science, technology, engineering, mathematics) research that they can translate into their K‐12 classrooms. Despite an increase in studies of RETs, there is a need for comparison of RET and non‐RET teachers' student outcomes.

Fractal Patch Antenna Based on Photonic Crystal for Enhanced Millimeter‐Wave Communication in Intelligent Transportation Systems

Radio Science, Volume 60, Issue 5, May 2025.
Abstract This paper introduces a Fractal Patch Antenna (FPA) integrated with Photonic Crystals (PhC) designed for Intelligent Transportation Systems (ITS) in the Millimeter‐wave bands (mmWaves) given the importance of the application of mmWaves in Vehicle‐to‐Everything (V2X) networks, we assumed, as examples, that the antenna is designed to resonate at

Disentangling the potential dark matter origin of LIGO's black holes

, 2017
The nature of dark matter remains one of the biggest open questions in physics. Intriguingly, it has been suggested that dark matter may be explained by another recently observed phenomenon: the detection of gravitational waves by LIGO.

Effects of mode degeneracy in the LIGO Livingston Observatory recycling cavity [PDF]

, 2007
We analyze the electromagnetic fields in a Pound-Drever-Hall locked, marginally unstable, Fabry-Perot cavity as a function of small changes in the cavity length during resonance.

Mirror Coating Research and Developments for Current and Future Gravitational‐Wave Detectors

Advanced Photonics Research, Volume 6, Issue 4, April 2025.
In gravitational‐wave detectors, research on mirror coatings is needed to mitigate thermal noise and enhance the detectors’ sensitivity. In this review, an overview of the latest worldwide research activities on coatings with low mechanical loss and low optical absorption is presented, including new coating designs such as multimaterial coatings and ...

Search for Gravitational Waves from Scorpius X-1 in LIGO O3 Data with Corrected Orbital Ephemeris

The Astrophysical Journal, 2023
Improved observational constraints on the orbital parameters of the low-mass X-ray binary Scorpius X-1 were recently published in Killestein et al. In the process, errors were corrected in previous orbital ephemerides, which have been used in searches ...

Situating Experience in Social Meaning: Stance, Salience, and Enregisterment

Journal of Sociolinguistics, Volume 29, Issue 2, Page 136-147, April 2025.
ABSTRACT This article uses mixed methods to establish how social meanings are situated in lived experiences. I test whether Greek listeners recognize features of Istanbul Greek (IG) and whether they associate the same social meanings with the variety as IG speakers. Results from a verbal guise experiment and metapragmatic stancetaking discourse suggest
