All-sky search for short gravitational-wave bursts in the second Advanced LIGO and Advanced Virgo run
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1186
We present the results of a search for short-duration gravitational-wave transients in the data from the second observing run of Advanced LIGO and Advanced Virgo. We search for gra…
H(II) centers in natural silica under repeated UV laser irradiations
F. Messina, M. Cannas, R. Boscaino
We investigated the kinetics of H(II) centers (=Ge'-H) in natural silica under repeated 266nm UV irradiations performed by a Nd:YAG pulsed laser. UV photons temporarily destroy the…
Nd:YAG laser induced E' centers probed by in situ absorption measurements
M. Cannas, F. Messina
We investigated various types of commercial silica irradiated with a pulsed Nd:YAG laser radiation (4.66 eV), with exposure time ranging up to 10000 s. Transient E' centers were pr…
An Optically Targeted Search for Gravitational Waves emitted by Core-Collapse Supernovae during the First and Second Observing Runs of Advanced LIGO and Advanced Virgo
The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +1195
We present the results from a search for gravitational-wave transients associated with core-collapse supernovae observed within a source distance of approximately 20 Mpc during the…
Optical properties of Ge-oxygen defect center embedded in silica films
F. Messina, S. Agnello, R. Boscaino +3
The photo-luminescence features of Ge-oxygen defect centers in a 100nm thick Ge-doped silica film on a pure silica substrate were investigated by looking at the emission spectra an…
Bleaching of optical activity induced by UV Laser exposure in natural silica
M. Cannas, F. Messina
We report experimental data on two types of natural silica, differing for their OH content, irradiated with UV photons (4.66 eV) from a pulsed Nd:YAG laser. Irradiation induces a r…
