Mapping the dynamics, star-formation rates, and chemical properties of galaxies with integral field spectroscopy [PDF]

, 2005
Major advances in the development of instruments for eight and ten meter class telescopes are revolutionising our understanding of galaxy formation. In particular, Integral Field Spectrographs (which produce a three dimensional {x, y, velocity) map of a ...

A Chandra Study of the Radio Galaxy NGC 326: Wings, Outburst History, and AGN Feedback [PDF]

, 2011
NGC 326 is one of the most prominent "X"- or "Z"-shaped radio galaxies (XRGs/ZRGs) and has been the subject of several studies attempting to explain its morphology through either fluid motions or reorientation of the jet axis. We examine a 100 ks

A Critical Eddington Ratio for X-shaped Radio Galaxies

The Astrophysical Journal
Abstract We derive a quantitative condition for the formation of X-shaped radio galaxies (XRGs) by evaluating the competition between black hole spin evolution and the radiative fading of relic plasma within our previously proposed framework.

Blackbody Quasar and Radio Source (BBQSORS): A Candidate of Transitional Little Red Dots with a T ∼ 104 K Blackbody Spectrum

The Astrophysical Journal Letters
JWST surveys have identified a new class of active galactic nuclei (AGNs) called little red dots (LRDs). Their observational properties challenge the canonical AGN paradigm and provide key insights into the early growth phase of the supermassive black ...

Removing the Effect of Source Structure From Correlated VLBI Data

Radio Science, Volume 61, Issue 10, October 2026.
Abstract Recent studies suggest that in geodetic very long baseline interferometry (VLBI) the assumption of sources being point‐like results in a significant residual error introduced by the effect of source structure. Our aim is to remove the impact of source structure from geodetic VLBI data right after the correlation step. For this purpose, we have

Features of Ground Level Enhancement (GLE #74) Event on 11 May 2024

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract Ground Level Enhancement (GLE #74) occurred on 11 May 2024 following an X5.8 solar flare from active region AR 13668 and the associated halo coronal mass ejection. The event was observed by both ground‐based neutron monitors (NMs) and space‐borne instruments and occurred during a deep Forbush decrease and one of the strongest geomagnetic ...

Radio sources in the Chandra Galactic Bulge Survey [PDF]

, 2012
We discuss radio sources in the Chandra Galactic Bulge Survey region. By cross-matching the X-ray sources in this field with the NRAO VLA Sky Survey archival data, we find 12 candidate matches.

Type‐III Solar Radio Bursts at Mars: A 16.5‐Year Catalog From Mars Express‐MARSIS at 0.1–5.5 MHz

Space Weather, Volume 24, Issue 10, October 2026.
Abstract The most intense radio feature in the Solar System are the solar Type‐III radio bursts, which are associated with electron beams that propagate along open magnetic field lines. Although solar radio bursts have been studied since the 1940s, observations remain mainly restricted within 1 AU.

A low‐cost, portable polarizing digital light microscope for monitoring crystal growth and for crystal harvesting

Journal of Applied Crystallography, Volume 59, Issue 5, Page 1693-1706, October 2026.
A low‐cost, portable, medium‐resolution polarizing digital light microscope device for monitoring crystal growth and for crystal harvesting is described. The device can be used with a cell phone or a personal computer for real‐time imaging by professional and amateur scientists alike.Motivated by the need for a convenient way to demonstrate the growth ...

Treadmill or Overground? Cognitive–Motor Interference Effects in Healthy Older Individuals

European Journal of Neuroscience, Volume 64, Issue 8, October 2026.
Although treadmill walking is widely used to study cognitive–motor interactions, its reflection of natural gait remains unclear. We compared dual‐tasking during treadmill and natural gait using mobile EEG and an auditory Go/No‐Go task. Natural gait imposed greater demands, increasing competition between cognitive and motor processes for shared ...
