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 ...

Graviton mass bounds from an analysis of bright star trajectories at the Galactic Center
EPJ Web of Conferences, 2017 In February 2016 the LIGO & VIRGO collaboration reported the discovery of gravitational waves in merging black holes, therefore, the team confirmed GR predictions about an existence of black holes and gravitational waves in the strong gravitational field

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

THE PAST AND THE FUTURE OF DIRECT SEARCH OF GW FROM PULSARS IN THE ERA OF GW ANTENNAS
Acta Polytechnica, 2013 In this paper we will give an overview of the past and present status of Gravitational Wave (GW) research associated with pulsars, taking into account the target sensitivity achieved from interferometric laser GW antennas such as Tama, Geo, Ligo and ...

Can We Draw Conclusions on Supernova Shock Wave Propagation Using Short‐Lived Radioactive Isotopes?
Astronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.ABSTRACT We run a three‐dimensional Galactic chemical evolution (GCE) model to follow the propagation of 53Mn (exclusively produced from type Ia supernovae, SNIa), 60Fe (exclusively produced from core‐collapse supernovae, CCSNe), 182Hf (exclusively produced from intermediate mass stars, IMSs), and 244Pu (exclusively produced from neutron star mergers ...

Gravitational waves from supercooled phase transitions in conformal Majoron models of neutrino mass
Journal of High Energy PhysicsWe study supercooled first-order phase transitions above the QCD scale in a wide class of conformal Majoron-like U(1)′ models that explain the totality of active neutrino oscillation data and produce a detectable stochastic gravitational wave background (

Dark Energy From the Gravitational Wave Background With Scalar Field Dark Matter
Astronomische Nachrichten, Volume 346, Issue 3-4, March-May 2025.ABSTRACT Recent observational results, such as those from pulsar timing arrays (PTA), suggest a low‐frequency Gravitational Wave Background (GWB) permeates our universe. This opens the possibility that gravitational waves could span a broader spectrum, potentially impacting cosmological scales.
