Light Echoes of Ancient Transients with the Blanco CTIO 4m Telescope
A. Rest, B. Sinnott, D. L. Welch +5
For over a century, light echoes have been observed around variable stars and transients. The discovery of centuries-old light echoes from supernovae in the Large Magellanic Cloud…
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…
Light Echoes of Transients and Variables in the Local Universe
A. Rest, B. Sinnott, D. L. Welch
Astronomical light echoes, the time-dependent light scattered by dust in the vicinity of varying objects, have been recognized for over a century. Initially, their utility was thou…
Light echoes reveal an unexpectedly cool Eta Carinae during its 19th-century Great Eruption
A. Rest, J. L. Prieto, N. R. Walborn +14
Eta Carinae (Eta Car) is one of the most massive binary stars in the Milky Way. It became the second-brightest star in the sky during its mid-19th century "Great Eruption," but the…
New g'r'i'z' Photometry of the NGC 5128 Globular Cluster System
B. Sinnott, A. Hou, R. Anderson +2
We present new photometry for 323 of the globular clusters in NGC 5128 (Centaurus A), measured for the first time in the filter system. The color indices are calibrated…
On the Interpretation of Supernova Light Echo Profiles and Spectra
A. Rest, B. Sinnott, D. L. Welch +5
The light echo systems of historical supernovae in the Milky Way and local group galaxies provide an unprecedented opportunity to reveal the effects of asymmetry on observables, pa…
Direct Confirmation of the Asymmetry of the Cas A Supernova with Light Echoes
A. Rest, R. J. Foley, B. Sinnott +21
We report the first detection of asymmetry in a supernova (SN) photosphere based on SN light echo (LE) spectra of Cas A from the different perspectives of dust concentrations on it…
