All-Sky Ultra-Narrowband Spectral Imaging with the OVRO-LWA: Technosignature Constraints and Axion-Like Particle Prospects
Nikita Kosogorov, Gregg Hallinan, Greg Hellbourg +46
We present an imaging-domain search for technosignatures at decametric wavelengths with the OVRO-LWA, targeting ultra-narrowband continuous-wave signals between 50 and 86 MHz. We i…
Implementation of a Near-Realtime Recording and Reporting System of Solar Radio Bursts
Peijin Zhang, Anastasia Kuske, Bin Chen +48
Strong solar activity is often accompanied by a variety of radio bursts. These bursts are valuable diagnostics of coronal and heliospheric processes and also have potential applica…
Estimating Electron Densities in the Middle Solar Corona using White-light and Radio Observations
Surajit Mondal, Shaheda Begum Shaik, Russell A. Howard +45
The electron density of the solar corona is a fundamental parameter in many areas of solar physics. Traditionally, routine estimates of coronal density have relied exclusively on w…
Searches for Prompt Low-Frequency Radio Counterparts to Gravitational Wave Event S250206dm with the OVRO-LWA Time Machine
Nikita Kosogorov, Gregg Hallinan, Casey Law +46
We report on a search for prompt, low-frequency radio emission from the gravitational-wave (GW) merger S250206dm using the Owens Valley Radio Observatory Long Wavelength Array (OVR…
Enigmatic centi-SFU and mSFU nonthermal radio transients detected in the middle corona
Surajit Mondal, Bin Chen, Sijie Yu +43
Decades of solar coronal observations have provided substantial evidence for accelerated particles in the corona. In most cases, the location of particle acceleration can be roughl…
Possible First Detection of Gyroresonance Emission from a Coronal Mass Ejection in the Middle Corona
Surajit Mondal, Bin Chen, Xingyao Chen +45
Routine measurements of the magnetic field of coronal mass ejections (CMEs) have been a key challenge in solar physics. Making such measurements is important both from a space weat…
Measuring the Magnetic Field of a Coronal Mass Ejection from Low to Middle Corona
Xingyao Chen, Bin Chen, Sijie Yu +44
A major challenge in understanding the initiation and evolution of coronal mass ejections (CMEs) is measuring the magnetic field of the magnetic flux ropes (MFRs) that drive CMEs.…
Probing the Turbulent Corona and Heliosphere Using Radio Spectral Imaging Observation during the Solar Conjunction of Crab Nebula
Peijin Zhang, Surajit Mondal, Bin Chen +41
Measuring plasma parameters in the upper solar corona and inner heliosphere is challenging because of the region's weakly emissive nature and inaccessibility for most in situ obser…
Detection of Echoes in PSR B1508+55 at frequencies below 100 MHz using the LWA1
Karishma Bansal, Greg Taylor, Kevin Stovall +1
PSR B1508+55 is known to have a single component profile above 300 MHz. However, when we study it at frequencies below 100 MHz using the first station of the Long Wavelength Array,…
New Limits on the Low-frequency Radio Transient Sky Using 31 hr of All-sky Data with the OVRO-LWA
M. M. Anderson, G. Hallinan, M. W. Eastwood +11
We present the results of the first transient survey from the Owens Valley Radio Observatory Long Wavelength Array (OVRO-LWA) using 31 hr of data, in which we place the most constr…
The Radio Sky at Meter Wavelengths: m-Mode Analysis Imaging with the Owens Valley Long Wavelength Array
Michael W. Eastwood, Marin M. Anderson, Ryan M. Monroe +17
A host of new low-frequency radio telescopes seek to measure the 21-cm transition of neutral hydrogen from the early universe. These telescopes have the potential to directly probe…
