The dust masses of powerful radio galaxies: clues to the triggering of their activity [PDF]
, 2014 We use deep Herschel Space Observatory observations of a 90% complete sample of 32 intermediate-redshift 2Jy radio galaxies (0.05 < z < 0.7) to estimate the dust masses of their host galaxies and thereby investigate the triggering mechanisms for their ...

ChemistryOpen, EarlyView.N‐terminal betaine conjugation modifies β‐peptide helices, influencing folding and self‐organization. For [1S, 2S]‐ACPC, folding to an H12 helix was unaffected, while [1R, 2R]‐ACHC formed an H14 helix instead of H10. Alternating heterochiral oligomers made of enantiomeric pairs of trans‐ACPC showed enhanced solubility and E‐strand formation.

Radio Emission of Nearby Early-type Galaxies in the Low and Very Low Radio Luminosity Range
The Astrophysical Journal, 2023 We analyze radio continuum emission of early-type galaxies with dynamical measurements of central supermassive black hole (SMBH) masses and well-characterized large-scale environments, but regardless of the exact level of the nuclear activity.

Radio Galaxy Zoo : host galaxies and radio morphologies derived from visual inspection [PDF]
, 2015 We present results from the first twelve months of operation of Radio Galaxy Zoo, which upon completion will enable visual inspection of over 170,000 radio sources to determine the host galaxy of the radio emission and the radio morphology.

Prioritized Real‐Time UAV‐Based Vessel Detection for Efficient Maritime Search
Journal of Field Robotics, EarlyView.ABSTRACT Real‐time vessel detection in maritime environments is crucial for diverse applications requiring speed and accuracy. Static camera views often introduce blind spots, compromising detection efficiency. This paper proposes a novel, real‐time UAV‐based system that uses a dynamic camera control strategy to address this limitation.

Hunting Gamma-Ray-emitting FR0 Radio Galaxies in Wide-field Sky Surveys
The Astrophysical Journal, 2023 The latest entry in the jetted active galactic nuclei (AGN) family is the Fanaroff–Riley type 0 (FR0) radio galaxies. They share several observational characteristics, e.g., nuclear emission and host galaxy morphology, with FR I sources; however, they ...

Radio Sources in the 2dF Galaxy Redshift Survey. I. Radio Source Populations [PDF]
, 1999 We present the first results from a study of the radio continuum properties of galaxies in the 2dF Galaxy Redshift Survey, based on thirty 2dF fields covering a total area of about 100 square degrees.

High-energy neutrinos from radio galaxies [PDF]
, 2014 The IceCube experiment has recently reported the first observation of high-energy cosmic neutrinos. Their origin is still unknown. In this paper, we investigate the possibility that they originate in active galaxies.

High‐Contrast Colorless‐to‐Colored Thermochromic Materials
Small, EarlyView.We developed new three‐component thermochromic systems showing reversible colorless‐to‐colored transition. Our general empirical rule applies to diverse fatty acid phase change materials and leuco dyes, enabling easily tunable transition temperature and activated colors (blue, cyan, green, pink, grey). Solid particles of these materials were integrated
