Study of nonthermal continuum patches : wave propagation and plasmapause study [PDF]

, 2011
Nonthermal continuum (NTC) radiation is believed to be emitted at the plasmapause and near the magnetic equator. We present a particular type of NTC radiation, referred to as NTC patch, which appears over a wide frequency range and within a relatively ...

Broadband VLA Spectral-line Survey of a Sample of Ionized Jet Candidates

The Astrophysical Journal Supplement Series, 2023
The study of the interaction between ionized jets, molecular outflows, and their environments is critical to understanding high-mass star formation, especially because jets and outflows are thought to be key in the transfer of angular momentum outward ...

Flat-spectrum Radio Continuum Emission Associated with ϵ Eridani [PDF]

The Astrophysical Journal, 2019
Abstract We present Very Large Array observations at 33.0 GHz that detect emission coincident with ϵ Eridani to within 0.″07 (0.2 au at the distance of this star), with a positional accuracy of 0.″05. This result strongly supports the suggestion of previous authors that the quiescent centimeter emission comes from the star and not from a

Radio continuum emission from knots in the DG Tauri jet [PDF]

Astronomy & Astrophysics, 2012
Context: HH 158, the jet from the young star DG Tau, is one of the few sources of its type where jet knots have been detected at optical and X-ray wavelengths. Aims: To search, using Very Large Array observations of this source, radio knots and if detected, compare them with the optical and X-ray knots.

Radio Continuum Emission and Optical Emission-Line Activity in the Nuclei of Spirals [PDF]

Symposium - International Astronomical Union, 1987
As a step towards the understanding of the phenomena occurring in galactic nuclei, we find that the ratio between the radio continuum emission of the nuclei of spiral galaxies and their optical luminosity is related to optical signs of nuclear activity, such as the emission line strengths of the H∝ and [NII] λ6584 lines.

Radio continuum and OH line emission of high-

, 2022
We present a study of the arcsecond-scale radio continuum and OH line emission of a sample of known OH megamaser (OHM) galaxies with z ≥ 0.15 using archival Very Large Array (VLA) data and also the results of our pilot Five-hundred-meter Aperture ...

Emerging experimental and computational methods for studying redox‐regulated structural transitions

FEBS Letters, EarlyView.
Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Radio continuum emission in ring galaxies

The Astronomical Journal, 1980
Radio emission was found in two (Arp 118 and Arp 148) of 27 ring-type galaxies searched with the NRAO interferometer to a detection limit of about 10 mJy at 11.1 cm. These two were also observed at 6 cm with the higher sensitivity and resolution of the VLA.

Effect of terahertz irradiation on DNA damage repair in living cells

FEBS Open Bio, EarlyView.
We investigated the effect of terahertz (THz) wave irradiation on DNA double‐strand break (DSB) repair in living cells. We found that THz irradiation enhanced DSB repair at specific frequencies, whereas heat treatment inhibited it, indicating that this effect is nonthermal and frequency‐specific.
