TL;DR: In this paper, the authors used the Karl G. Jansky Very Large Array (VLA) in the C-array configuration and a large program to observe the HI 21 cm line, four OH lines, nineteen Hn alpha radio recombination lines as well as the continuum emission from 1 to 2 GHz in full polarization over a large part of the first Galactic quadrant.

TL;DR: In this article, the authors presented the first half of the HI/OH/Recombination line survey of the Milky Way (THOR) and compared the results from the different datasets.
Journal ArticleDOI
Binary orbits as the driver of γ-ray emission and mass ejection in classical novae
Laura Chomiuk,Justin D. Linford,Jun Yang,Tim O'Brien,Zsolt Paragi,Amy J. Mioduszewski,Robert Beswick,C. C. Cheung,Koji Mukai,T. J. N. Nelson,Valério A. R. M. Ribeiro,Michael P. Rupen,J. L. Sokoloski,Jennifer Weston,Yong Zheng,Michael F. Bode,S. P. S. Eyres,Nirupam Roy,G. B. Taylor +18 more
TL;DR: High-resolution radio imaging of the γ-ray-emitting nova V959 Mon finds that its ejecta were shaped by the motion of the binary system: some gas was expelled rapidly along the poles as a wind from the white dwarf, while denser material drifted out along the equatorial plane, propelled by orbital motion.
Journal ArticleDOI
Galactic Supernova Remnant Candidates Discovered by THOR
L. D. Anderson,L. D. Anderson,Yi-Fan Wang,S. Bihr,Michael Rugel,Henrik Beuther,Frank Bigiel,Ed Churchwell,Simon C. O. Glover,Alyssa A. Goodman,Th. Henning,Mark H. Heyer,Ralf S. Klessen,H. Linz,Steven N. Longmore,Karl M. Menten,Juergen Ott,Nirupam Roy,Juan D. Soler,Jeroen Stil,James Urquhart,James Urquhart +21 more
TL;DR: In this paper, the authors used the combination of high-resolution 1-2 GHz continuum data from The HI, OH, Recombination line survey of the Milky Way (THOR) and lower-resolution VLA 14 GHz Galactic Plane Survey (VGPS) continuum data, together with MIR data from the Spitzer GLIMPSE, Spitzer MIPSGAL, and WISE surveys to identify SNR candidates.

TL;DR: In this article, a large-scale survey of the Milky Way has been conducted to study the atomic, molecular and ionized emission of giant molecular clouds (GMCs) at 20" resolution, and the authors have shown that the column densities are as high as N(HI)~150 M_sun/pc^2 ~ 1.9x10^22 cm^-2.
