Fuzzy Galaxies or Cirrus? Decomposition of Galactic Cirrus in Deep Wide-Field Images
Qing Liu, Roberto Abraham, Peter G. Martin +12
Diffuse Galactic cirrus, or Diffuse Galactic Light (DGL), can be a prominent component in the background of deep wide-field imaging surveys. The DGL provides unique insights into t…
SpectAcLE: An Improved Method for Modeling Light Echo Spectra
Roee Partoush, Armin Rest, Jacob E. Jencson +17
Light echoes give us a unique perspective on the nature of supernovae and non-terminal stellar explosions. Spectroscopy of light echoes can reveal details on the kinematics of the…
A Search for Supernova Light Echoes in NGC 6946 with SITELLE
M. C. Radica, D. Welch, L. Rousseau-Nepton
We present the analysis of four hours of spectroscopic observations of NGC 6946 with the SITELLE Imaging Fourier Transform Spectrometer on the Canada-France-Hawaii Telescope, acqui…
Light Echoes of Historic Transients
A. Rest, B. Sinnott, D. L. Welch +2
Light echoes, light from a variable source scattered off dust, have been observed for over a century. The recent discovery of light echoes around centuries-old supernovae in the Mi…
Asymmetry in the Outburst of SN 1987A Detected Using Light Echo Spectroscopy
B. Sinnott, D. L. Welch, A. Rest +2
We report direct evidence for asymmetry in the early phases of SN 1987A via optical spectroscopy of five fields of its light echo system. The light echoes allow the first few hundr…
The ongoing pursuit of R Coronae Borealis stars: ASAS-3 survey strikes again
P. Tisserand, G. C. Clayton, D. L. Welch +3
R Coronae Borealis stars (RCBs) are rare, hydrogen-deficient, carbon-rich supergiant variable stars that are likely the evolved merger products of pairs of CO and He white dwarfs.…
