Can Reverberation-measured Quasars Be Used for Cosmology? [PDF]
Astrophysical Journal, 2019 Quasars have been proposed as a new class of standard candles analogous to supernovae, since their large redshift range and high luminosities make them excellent candidates.

Supermassive Black Holes in Active Galactic Nuclei. I. The Consistency of Black Hole Masses in Quiescent and Active Galaxies [PDF]
, 2001 We report the first results of a program to measure accurate stellar velocity dispersions in the bulges of the host galaxies of active galactic nuclei (AGNs) for which accurate black hole (BH) masses have been determined via reverberation mapping.

WFUMB position paper on reverberation artefacts in lung ultrasound: B-lines or comet-tails?
Medical ultrasonography, 2020 The analysis of vertical reverberation artefacts is an essential component of the differential diagnosis in pulmonary ultra-sound. Traditionally, they are often, but not exclusively, called B-line artefacts (BLA) and/or comet tail artefacts (CTA), but ...

Effects of virtual acoustics on dynamic auditory distance perception [PDF]
, 2017 Sound propagation encompasses various acoustic phenomena including reverberation. Current virtual acoustic methods, ranging from parametric filters to physically-accurate solvers, can simulate reverberation with varying degrees of fidelity.

Impact of Temperature and Relative Humidity on Reverberation Time in a Reverberation Room
Buildings, 2022 Changes in acoustic parameters measured in a room may depend on the location and orientation of the sound source and microphones or on the reverberation conditions of the room.

Reverberation Mapping of Luminous Quasars at High z [PDF]
Astrophysical Journal, 2018 We present reverberation mapping (RM) results for 17 high-redshift, high-luminosity quasars with good-quality R-band and emission-line light curves. We are able to measure statistically significant lags for Lyα (11 objects), Si iv (5 objects), C iv (11 ...

Tracing the reverberation lag in the hard state of black hole X-ray binaries [PDF]
, 2015 We report results obtained from a systematic analysis of X-ray lags in a sample of black hole X-ray binaries, with the aim of assessing the presence of reverberation lags and studying their evolution during outburst.

Determination of the Reverberation Time Using the Measurement of Sound Decay Curves
Applied Sciences, 2023 In the measurements of reverberation time, measurement methods of different accuracy are used depending on the room. For ordinary rooms, the measurements are made using the interrupted noise method, which consists of determining the decay curve after ...
