VLASS Discovery of a Luminous Galactic Radio Transient Evolving on Decade Timescales
Jessie M. Miller, Gregg Hallinan, Dillon Dong +10
We present a multiwavelength analysis of the radio transient VT J1906+0849, discovered as a 70 mJy source in Epoch 1 of the Very Large Array Sky Survey (VLASS), 21 yr after an NRAO…
A spectacular multi-wavelength transient associated with an off-axis relativistic jet
Delina Levine, Gregg Hallinan, Jean J. Somalwar +10
Many of the most luminous extragalactic transients originate from the accretion of material onto a black hole (BH) via core-collapse, stellar mergers, or the tidal disruption of a…
The Karl G. Jansky Very Large Array Sky Survey (VLASS). Data Products
Amy Kimball, Mark Lacy, Juergen Ott +5
The VLA Sky Survey (VLASS) is a radio continuum survey of the entire sky visible to the VLA (dec > -40deg) at ~2.5 arcsecond resolution over 2-4 GHz with full polarization. Data pr…
Fast Luminous Extragalactic Transients in the VLA Sky Survey: Implications for the rates of Accretion-Induced Collapse Events, Fast Blue Optical Transients and Gamma Ray Burst Afterglows
Kritti Sharma, Vikram Ravi, Dillon Z. Dong +7
Radio wavelengths offer a unique window into high-energy astrophysical phenomena that may be obscured or too rapidly evolving to be captured at other wavelengths. Leveraging data f…
Detection of Radio Emission from Super-flaring Solar-Type Stars in the VLA Sky Survey
Ivey Davis, Gregg Hallinan, Carlos Ayala +2
Solar-type stars have been observed to flare at optical wavelengths to energies much higher than observed for the Sun. To date, no counterparts have been observed at longer wavelen…
VLASS tidal disruption events with optical flares I: the sample and a comparison to optically-selected TDEs
Jean J. Somalwar, Vikram Ravi, Dillon Z. Dong +11
In this work, we use the Jansky VLA Sky Survey (VLASS) to compile the first sample of six radio-selected tidal disruption events (TDEs) with transient optical counterparts. While w…
