Reply to Comment by Lamy et al. on “Locating the source field lines of Jovian decametric radio emissions”

open access: yesEarth and Planetary Physics, 2022
Locating the source of decametric (DAM) radio emissions is a key step in the use of remote radio observations to understand the Jovian magnetospheric dynamics and their interaction with the planet’s moons. Wang YM et al.

Cassini observations of ion and electron beams at Saturn and their relationship to infrared auroral arcs [PDF]

open access: yes, 2005
We present Cassini Visual and Infrared Mapping Spectrometer observations of infrared auroral emissions from the noon sector of Saturn's ionosphere revealing multiple intense auroral arcs separated by dark regions poleward of the main oval.

Cyclotron absorption of radio emission within pulsar magnetospheres [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2001
ABSTRA C T Absorption of radio emission through normal cyclotron resonance within pulsar magnetospheres is considered. The optical depth for cyclotron damping is calculated using a plasma distribution with an intrinsically relativistic spread. We argue that such a broad distribution is plausible for pulsar plasmas and that it implies that a class of ...

Radio Emission from UV Cet: Auroral Emission from a Stellar Magnetosphere

open access: yesThe Astrophysical Journal, 2022
Abstract The archetypical flare star UV Cet was observed by MeerKAT on 2021 October 5–6. A large radio outburst with a duration of ∼2 hr was observed between 886 and 1682 MHz, with a time resolution of 8 s and a frequency resolution of 0.84 MHz, enabling sensitive dynamic spectra to be formed. The emission is characterized by three peaks

Radio emission from mini‐magnetospheres on the Moon [PDF]

open access: yesGeophysical Research Letters, 2004
Small‐scale, localized magnetic anomalies on the surface of planetary satellites effectively create “mini‐magnetospheres”, which can lead to standoff shocks analogous to planetary bow shocks. This gives rise to the tantalizing possibility that radio emission can be produced in the vicinity of such mini‐magnetospheres, since it is well known that radio ...

Constraints on magnetospheric radio emission from Y dwarfs [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2019
Abstract As a pilot study of magnetism in Y dwarfs, we have observed the three known infrared variable Y dwarfs WISE J085510.83−071442.5, WISE J140518.40+553421.4, and WISEP J173835.53+273258.9 with the NSF’s Karl G. Jansky Very Large Array in the 4–8 GHz frequency range.

Electromagnetic Precursors to Black Hole–Neutron Star Gravitational Wave Events: Flares and Reconnection-powered Fast Radio Transients from the Late Inspiral

open access: yesThe Astrophysical Journal Letters, 2023
The presence of magnetic fields in the late inspiral of black hole–neutron star binaries could lead to potentially detectable electromagnetic precursor transients.

Stellar wind-magnetosphere interaction at exoplanets: computations of auroral radio powers

open access: yes, 2016
We present calculations of the auroral radio powers expected from exoplanets with magnetospheres driven by an Earth-like magnetospheric interaction with the solar wind.

High-latitude propagation studies using a meridional chain of LF/MF/HF receivers [PDF]

open access: yesAnnales Geophysicae, 2004
For over a decade, Dartmouth College has operated programmable radio receivers at multiple high-latitude sites covering the frequency range 100-5000kHz with about a 1-s resolution. Besides detecting radio emissions of auroral origin, these receivers
