The Radio Wave Polarization of Saturn Lightning Observed by Cassini
Journal of Geophysical Research: Space Physics, Volume 130, Issue 6, June 2025.Abstract We investigate the polarization of the radio waves emitted by lightning in Saturn's atmosphere, which are referred to as SEDs for Saturn Electrostatic Discharges. Using the complete SED data set retrieved by Cassini's RPWS (Radio and Plasma Wave Science) instrument we found that the circular polarization of SEDs below a frequency of 2 MHz ...

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 2, June 2025.Abstract End‐member mixing analysis (EMMA) is widely used to analyze geoscience data for their end‐members and mixing proportions. Many traditional EMMA methods depend on known end‐members, which are sometimes uncertain or unknown. Unsupervised EMMA methods infer end‐members from data, but many existing ones don't strictly follow necessary constraints ...

The peculiar radio galaxy 3C 433
, 1983 Radio, optical, and x-ray observations are presented of the peculiar radio galaxy 3C 433. Two basic features characterize the radio morphology: namely, a striking asymmetry in the strength and shape of the radio emission and an overall x-shaped structure.

Mapping the particle acceleration in the cool core of the galaxy cluster RX J1720.1+2638
, 2014 We present new deep, high-resolution radio images of the diffuse minihalo in the cool core of the galaxy cluster RX J1720.1+2638. The images have been obtained with the Giant Metrewave Radio Telescope at 317, 617 and 1280 MHz and with the Very Large ...

Black hole masses and starbursts in X-shaped radio sources
, 2011 It has been suggested that the X-shaped morphology observed in some radio sources can reflect either a recent merger of two supermassive black holes (SMBHs) or the presence of a second active black hole in the galactic nucleus. These scenarios are tested

Revealing A Head-on Major Merger in the Nearby NGC 6338 Group with Chandra and VLA observations
, 2019 By analyzing the Chandra archival data of the nearby NGC 6338 galaxy group, we identify two X-ray bright clumps (N-clump and S-clump) within the central 100 kpc, and detect an arc-like X-ray brightness discontinuity at the south boundary of the N-clump ...

Monthly Notices of the Royal Astronomical SocietyABSTRACT We present the study of multimessenger signatures of massive black hole (MBH) binaries residing in the centres of galaxy merger remnants. In particular, we first focus on the gravitational wave background (GWB) produced by an ensemble of MBH binary inspirals in the frequency range probed by the Pulsar Timing Array (PTA ...

Chandra Observation of M84, Radio Lobe Elliptical in Virgo cluster
, 2000 We analyzed a deep Chandra observation of M84, a bright elliptical galaxy in the core of the Virgo cluster. We find that the spatial distribution of the soft X-ray emission is defined by the radio structure of the galaxy.
