Ejecta Knot Flickering, Mass Ablation, and Fragmentation in Cassiopeia A
Robert A. Fesen, Jordan A. Zastrow, Molly C. Hammell +2
Ejecta knot flickering, ablation tails, and fragmentation are expected signatures associated with the gradual dissolution of high-velocity supernova (SN) ejecta caused by their pas…
The Chemical Distribution in a Subluminous Type Ia Supernova: HST Images of the SN 1885 Remnant
Robert A. Fesen, Peter A. Hoeflich, Andrew J. S. Hamilton +4
We present HST images of the remnant of SN 1885 seen in absorption against M31's bulge via resonance lines of Ca I, Ca II, Fe I, and Fe II. Viewed in CaII H & K line absorption, th…
The Expansion Asymmetry and Age of the Cassiopeia A Supernova Remnant
R. A. Fesen, M. C. Hammell, J. Morse +7
HST ACS images of the young SN remnant Cas A are used to explore the expansion and spatial distribution of its highest velocity debris. Proper motions of over 1800 outlying ejecta…
Discovery of Outlying, High-Velocity Oxygen-Rich Ejecta in Cassiopeia A
R. A. Fesen, M. C. Hammell, J. Morse +7
Hubble Space Telescope images of the young Galactic supernova remnant Cassiopeia A reveal a far larger population of outlying, high-velocity knots of ejecta with a broader range of…
Late-time X-Ray, UV and Optical Monitoring of Supernova 1979C
Stefan Immler, Robert A. Fesen, Schuyler D. Van Dyk +8
We present results from observations of SN 1979C with XMM-Newton in X-rays and in the UV, archival X-ray and HST data, and follow-up ground-based optical imaging. The XMM-Newton MO…
The Oxford-Dartmouth Thirty Degree Survey I: Observations and Calibration of a Wide-Field Multi-Band Survey
Emily C. MacDonald, Paul Allen, Gavin Dalton +13
The Oxford Dartmouth Thirty Degree Survey (ODTS) is a deep, wide, multi-band imaging survey designed to cover a total of 30 square degrees in BVRi'Z, with a subset of U and K band…
