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…
