One issue of interest pertaining to the development of a numerical model applicable to the nonlinear propagation of jet noise is the behavior of spectral predictions at large distances. In this study, a recorded noise waveform from a military jet aircraft is numerically propagated via a hybrid time-frequency domain solution to the generalized Burgers equation that incorporates spherical spreadi...

We compute the differential distributions of two three-jet event-shape observables at the next-to-leading order accuracy at fixed values of the DIS kinematic variables. The observable Kout measures the out-of-event-plane momentum. The other observable y3 is the maximum value of the ycut resolution variable for which an event is classified as three-jet event. We also show the dependence of the f...

We present the results of QCD analysis of out-of-event-plane momentum distribution in 3-jet ee annihilation events. We consider the all-order resummed perturbative prediction and the leading power suppressed non-perturbative corrections to the mean value 〈Kout〉 and the distribution and explain their non-trivial colour structure. The technique we develop aims at improving the accuracy of the the...

Microquasars (black hole X-ray binaries with relativistic jets) are first found by means of multiwavelengths observations with ground-based telescopes. Microquasars mimic, on a much smaller scale, many of their phenomena seen in quasars. The study about microquasars opens the door for better understanding of the relativistic jets elsewhere in the Universe, and may serve to determine the distanc...

We construct the eROSITA X-ray catalog of radio galaxies discovered by WERGS survey that is made cross-matching wide-area Subaru/HSC optical and VLA/FIRST 1.4 GHz survey. find 393 detected in 0.5--2 keV band eFEDS field covering 140~deg$^2$. Thanks to wide medium depth survey, sample contains rare most luminous above knee luminosity function, spanning 44<log L(0.5-2keV,abs)<46.5 at $1<z<4$. Bas...

High-pt particles produced in nucleus-nucleus collisions constitute a powerful tool to study the medium properties. The energy loss resulting from the propagation of these particles in the produced medium translates into a suppression of the high-pt yields. These effects are usually associated to medium-induced gluon radiation which, in turn, predicts a broadening of the jet-like signals. Both ...

Black hole accretion and jet production are areas of intensive study in astrophysics. Recent work has found a relation between radio luminosity, X-ray luminosity, and black hole mass. With the assumption that radio and X-ray luminosity are suitable proxies for jet power and accretion power, respectively, a broad fundamental connection between accretion and jet production is implied. In an effor...

The rovibrationally resolved Fourier transform (FT) far infrared (FIR) spectra of two intermolecular librations of (HF)3, namely the in-plane ν6 and out-of-plane ν4 bending fundamentals centered, respectively, at about 494 cm(-1) and 602 cm(-1), have been recorded for the first time under jet-cooled conditions using the supersonic jet of the Jet-AILES apparatus. The simultaneous rotational anal...
